Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The HTTP2.0 protocol is a relatively new communication protocol, and when a client communicates with a web server, if the HTTP2.0 protocol is to be implemented, it is also an important consideration that, on one hand, the client can support and use the protocol, and on the other hand, how the server specifies the behavior of the client, so that the client can be used in a relatively safe range to ensure the overall service quality.
In view of the problems that the conventional mode for starting the HTTP2.0 service for a specific domain name is poor in operation convenience and can reduce the stability of the network service of the server, the method, the apparatus, and the electronic device for processing an access request according to the embodiments of the present invention may be applied to various application scenarios of the domain name access service. For the convenience of understanding the present embodiment, a method for processing an access request disclosed in the embodiment of the present invention will be described in detail first.
Referring to fig. 1, there is shown a flow chart of a method for processing an access request, as seen in fig. 1, the method comprising the steps of:
step S102: an access request of a client for a specified domain name is received.
Here, the method may be executed on a web server, and the web server may be a device of a certain node in a Content Delivery Network (CDN) and is used to provide a domain name access service for a client.
The access request includes a specified domain name requested to be accessed by the client, for example, if the access request requests to access the hundred-degree homepage, the domain name corresponding to the hundred-degree homepage is carried in the access request, that is, https:// www.baidu.com/.
Step S104: and if the access request carries the communication protocol requirement, determining whether the current protocol configuration of the specified domain name conforms to the communication protocol requirement.
Here, the protocol configuration refers to a communication protocol configured in advance in the server, and for example, for web page access, the communication protocol may be an http protocol. The http protocol is a simple request-response protocol, which typically runs on top of TCP, and specifies what messages a client may send to a server and what responses to get.
In one possible implementation, it may be determined whether the current protocol configuration of the specified domain name meets the communication protocol requirement according to a preset static domain name configuration. Here, the static domain name refers to a domain name pointing to a fixed IP address, and communication protocols are configured for the specified static domain name in the server, so that when a client accesses any one of the static domain names, communication is performed using a pre-configured communication protocol.
In this embodiment, after receiving an access request from a client, a server determines whether the access request carries a communication protocol requirement, and if so, determines whether the current protocol configuration of the specified domain name meets the communication protocol requirement; if not, the access request is responded according to the communication protocol in the current protocol configuration. The communication protocol requirement may be a communication protocol of a specified version, for example, the communication protocol requirement is an HTTP1.0 protocol, an HTTP1.1 protocol, an HTTP2.0 protocol, or the like. And when the client requests the domain name access with the communication protocol of the specified version, the client is indicated to support the communication protocol of the specified version. For example, assuming that a client requires access to a specified domain name in the HTTP2.0 protocol, the client itself must support conditions (including requirements of software and hardware, etc.) required for communication in the HTTP2.0 protocol.
Step S106: if the current protocol configuration does not meet the communication protocol requirement, judging whether the user is pre-configured with a standby protocol configuration aiming at the specified domain name.
For example, assume that the current protocol is configured to: for an access request of any domain name, an HTTP1.1 protocol is configured; and if the communication protocol requirement carried in the access request received from the client side is that the specified domain name is required to be accessed by the HTTP1.1 protocol, judging that the current protocol configuration conforms to the communication protocol requirement, and responding to the access request according to the communication protocol in the current protocol configuration.
Similarly, under the current protocol configuration, if the client requests to access the specified domain name by the HTTP2.0 protocol, it is determined that the current protocol configuration does not meet the requirement of the communication protocol, and at this time, it is determined whether the user has preconfigured a standby protocol configuration for the specified domain name. Here, the backup protocol configuration is configured by a user, for example, in the CDN network service, a server side may provide a platform, to which a communication protocol corresponding to a domain name is configurable, for a server tenant side, so that the tenant side may set a backup communication protocol for specifying the domain name according to its own service requirement, so that when a client accesses the specified domain name, the client may access the specified domain name according to the set backup communication protocol in a case where the client supports the backup communication protocol. Therefore, the user can more flexibly and conveniently configure the communication protocol corresponding to the domain name.
Step S108: if a backup protocol configuration is configured and the backup protocol configuration conforms to the communication protocol requirements, the access request is responded to according to the communication protocol in the backup protocol configuration.
In actual operation, if the user does not configure the standby protocol configuration for the specified domain name, or, although the user configures the standby protocol configuration for the specified domain name, the standby protocol configuration does not meet the communication protocol requirement, for example, the communication protocol version in the standby protocol configuration is higher or lower than the communication protocol version required by the communication protocol, the access request is still responded according to the communication protocol in the current protocol configuration.
And if the user configures the standby protocol configuration for the specified domain name and the standby protocol configuration meets the requirements of the communication protocol, responding to the access request according to the communication protocol in the standby protocol configuration. For example, the communication protocol requires HTTP2.0 communication protocol, and the backup protocol configuration for the specified domain name is also HTTP2.0, then the access request of the client is responded according to the HTTP2.0 communication protocol, that is, communication is performed between the client and the server according to the HTTP2.0 communication protocol.
It can be seen that, in this embodiment, if the client performs domain name access and requests a specific protocol to perform domain name access, when the server determines which protocol is used to respond to the access request, the priority of the current protocol configuration (such as static domain name configuration) in the server is higher than the priority of the standby protocol configuration configured by the user; and the standby protocol configuration has a higher priority than the protocol configuration indicated by the client to be supported in the access request.
The method for processing the access request provided by the embodiment of the invention receives the access request of the client aiming at the specified domain name; if the access request carries a communication protocol requirement, determining whether the current protocol configuration of the specified domain name meets the communication protocol requirement; if the current protocol configuration does not meet the communication protocol requirement, judging whether the user is pre-configured with a standby protocol configuration aiming at the specified domain name; if a backup protocol configuration is configured and the backup protocol configuration conforms to the communication protocol requirements, the access request is responded to according to the communication protocol in the backup protocol configuration. In the mode, a user presets the standby protocol configuration of the specified domain name, and when the current protocol configuration accessed to the specified domain name in the web server does not meet the communication protocol requirement of the client, the communication protocol meeting the requirement of the client can be configured according to the standby protocol configuration, so that the communication protocol configuration of the domain name can be configured more flexibly.
On the basis of the method for processing an access request shown in fig. 1, the present embodiment further provides another method for processing an access request, and the method mainly describes a specific implementation process of step S106 (if the current protocol configuration does not meet the communication protocol requirement, determine whether the user is preconfigured with the standby protocol configuration for the specified domain name) in the foregoing embodiment.
Referring to fig. 2, a flow chart of another method for processing an access request is shown, wherein the method includes the following steps:
step S202: an access request of a client for a specified domain name is received.
Here, step S202 in this embodiment corresponds to step S102 in the foregoing embodiment, and corresponding descriptions may refer to corresponding parts of the foregoing embodiment, which are not described herein again.
Step S204: judging whether the access request carries a communication protocol requirement or not; if yes, go to step S206; if not, step S216 is performed.
If the access request carries a communication protocol requirement, further judging whether the current protocol configuration of the specified domain name meets the communication protocol requirement; and if the access request does not carry the communication protocol requirement, responding to the access request according to the communication protocol in the current protocol configuration.
Step S206: judging whether the current protocol configuration of the specified domain name meets the requirement of the communication protocol; if yes, go to step S216; if not, step S208 is performed.
If the current protocol configuration of the specified domain name meets the requirement of the communication protocol, responding the access request according to the communication protocol in the current protocol configuration; and if the current protocol configuration of the specified domain name does not meet the requirement of the communication protocol, reading the user configuration loaded in advance in the specified memory, and acquiring the standby protocol configuration of the specified domain name according to the user configuration.
Step S208: and reading the user configuration preloaded in the appointed memory.
Here, the user configuration preloaded in the specified memory may be read through a callback function, where the callback function is a function called through a function pointer, and the specified memory may be a shared memory in the server.
In at least one possible embodiment, the loading of the user configuration into the specified memory may be implemented by the following steps 11-13:
(11) and acquiring user configuration generated by a preset terminal.
In actual operation, a server leasing party can provide a platform for a tenant party, so that the tenant can log in the platform for operation through the terminal to configure access parameters in a designated server according to self requirements, and user configuration is obtained.
Here, the user configuration may or may not include the standby protocol configuration of the specified domain name, and if the standby protocol configuration of the specified domain name is included, it indicates that the user configures the standby protocol for the specified domain name. In other possible embodiments, the user configuration may also include other configurations, such as a configuration of access rights of the client, and the like, which is not limited herein.
In one possible implementation manner, a communication protocol switch associated with a specified domain name may be set in a preset interactive interface of the terminal, and when the terminal receives an on instruction for the communication protocol switch, a standby protocol configuration of the specified domain name is generated. As shown in fig. 3, which is an operation interface diagram of a standby protocol configuration, in the embodiment shown in fig. 3, a selection switch of the HTTP2.0 protocol for specifying a domain name a is provided, and a user can select to turn on or off the selection switch to obtain the standby protocol configuration for the domain name a. Here, the format of the user configuration may be a json string, for example, in the example of fig. 3, after clicking on the open option of HTTP2.0, a service configuration in the form of a json string of the domain name a is generated as follows:
{"host":"xxx.yyy.zzz","conf":[{"http2":"on","location":"\\/","loc_conf":{...}}]}。
(12) the user profile is saved as a profile with a fixed file name.
In actual operation, the server may read the user configuration generated by the preset terminal from the specified memory through a preset protocol. And, the read user configuration is saved to the configuration file with the fixed file name in the server.
(13) And loading the configuration file to a specified memory.
In one possible implementation, the update state of the configuration file is monitored, and if the configuration file is monitored to be updated, the updated configuration file is loaded to a specified memory. Therefore, if the communication protocol of the user aiming at the domain name is modified, the server can timely acquire the latest user configuration so as to respond the access request of the client to the specified domain name according to the communication protocol required by the user.
Step S210: determining whether the user configuration contains a standby protocol configuration for the specified domain name; if yes, go to step S212; if not, step S216 is performed.
If the user configuration comprises a standby protocol configuration aiming at the specified domain name, judging that the standby protocol configuration meets the communication protocol requirement, and responding to the access request based on the judgment result; if the user configuration does not contain a backup protocol configuration for the specified domain name, the access request is responded to according to the communication protocol in the current protocol configuration.
Step S212: judging that the standby protocol configuration meets the communication protocol requirement; if yes, go to step S214; if not, step S216 is performed.
If the standby protocol configuration conforms to the communication protocol requirement, responding to the access request according to the communication protocol in the standby protocol configuration; if the standby protocol configuration does not meet the communication protocol requirements, the access request is responded according to the communication protocol in the current protocol configuration.
Step S214: the access request is responded to according to a communication protocol in the standby protocol configuration.
And establishing a communication connection between the client and the server according to the communication protocol of the specified domain name configured in the standby protocol configuration, so that the client can access the specified domain name through the communication protocol.
Step S216: the access request is responded to according to a communication protocol in the current protocol configuration.
And establishing communication connection between the client and the server according to the communication protocol of the specified domain name configured in the current protocol configuration, and providing domain name access service for the client.
In this embodiment, the server responding to the client access request may be a Nginx web server, and the web server pulls the user configuration from the user terminal through a protocol, and stores the user configuration in the device as a configuration file with a fixed name, and when the configuration file is read and found to be changed, reloads the configuration file, and places the configuration file in a shared memory of the Nginx. When an access request of a client aiming at a specified domain name reaches a Nginx server, if the static server block configuration of the specified domain name cannot be found on the server, entering a default _ server block, wherein the default _ server block is used for reading the domain name configuration so as to select whether to start a corresponding protocol service.
Referring to fig. 4, which is a schematic diagram illustrating a process of selecting an HTTP2.0 protocol in a hello phase of a server, in an embodiment shown in fig. 4, after a client sends a client hello packet to a server, the server reads the packet and performs corresponding processing, for example, selecting a version of the protocol (TLS1.0, TLS1.1, TLS1.2, etc.), and then selects an ALPN protocol through a function, where the protocols such as HTTP1.0, HTTP1.1, HTTP2.0, etc. may be selected, where a callback function is redefined in the function, and a user configuration in a shared memory is called and loaded in s- > ctx- > set _ ALPN _ cb; and when selecting a protocol, the callback function refers to the static domain name configuration and the standby protocol configuration of the domain name, and determines the final application layer protocol in tls1_ alpn _ handle _ client _ hello _ late.
In the method for processing an access request provided by this embodiment, a user may quickly configure the standby protocol configuration through an external device (e.g., a user terminal) in communication connection with the web server, so as to meet a communication protocol requirement when the client accesses the specified domain name, without operating a static domain name configuration on the web server or reloading the configuration of the server, thereby improving the stability of the network service of the server.
