Figure 2 is a schematic flowchart of a file downloading method provided by an embodiment of the present application. As shown in Figure 2, the method includes the following steps S110-S150.

S110. Obtain at least one target download task sent by the target application in the target device.

In this embodiment, when there are multiple target download tasks, the multiple target download tasks may come from one or more target applications in the target device.

Specifically, when the target application needs to download target file data, the corresponding target download task will be sent to the file download device in the target device.

S120: Determine the priority of each target download task according to a preset priority policy.

In some embodiments, the priority policy includes a first priority policy, a second priority policy, or a third priority policy, wherein:

The first priority strategy includes: determining the priority of the target download task according to a preset priority correspondence, wherein the priority correspondence includes a correspondence between a data type identifier and a priority.

At this time, each target download task carries a target data type identifier. The target data type identifier can be the data attribute identifier of the data itself, or the scene type identifier of the data generation, that is, in the priority correspondence relationship, for different data Generation scenarios or different data attributes are set with different priorities. Among them, the data generation scenarios include application page opening scenarios, chat box receiving file scenarios, and file active download scenarios. Among them, data attributes include pictures, word documents, and ppt documents. And h5 page data, etc.

The second priority strategy includes: determining the priority of the target download task according to the priority information carried in the target download task.

At this time, each target download task carries priority information, which is set by the user when the user triggers the corresponding download task, or is preset by the user in the corresponding target application, where, The priority information includes a level of priority.

The third priority strategy includes: if the target download task carries priority information, the priority will be determined based on the priority information carried. If the target download task does not carry priority information, then the target of the target download task will be further obtained. data type identifier, and then determine the priority of the target download task according to the corresponding relationship between the target data type identifier and the priority (if no priority information is carried, refer to the first priority policy).

At this time, step S120 includes: if the target download task carries priority information, determining the priority of the target download task according to the priority information; if the target download task does not carry priority information, Then, the priority of the target download task is determined according to the corresponding relationship between the target data type identifier of the target download task and the preset priority. At this time, the target download task may carry priority information (if the user has set it, it will be carried), or it may not carry priority information.

S130. Add each target download task to the download operation queue of the target device according to the priority of each target download task.

Wherein, the download tasks in the download operation queue are arranged in order from high to low priority, and those with priority are downloaded first.

In this embodiment, the download operation queue is used to sort candidate download tasks to be executed according to priority. Before adding the target download task, one or more candidate download tasks may already exist in the download operation queue. Each candidate download task Tasks have their corresponding priorities. At this time, the target download task can be inserted into the download operation queue according to the priority; in addition, if there are no candidate download tasks in the download operation queue before adding the target download task, at this time, Sort directly according to the priority of each target download task in the download operation queue.

S140. For each target download task, determine whether the current download task in the download operation queue includes the target download task.

In this embodiment, the downloader will report the download status to the download operation queue in real time. For example, it will report the current number of idle download locations to the download operation queue in real time. The download operation queue will select the current idle download with the highest priority from the download operation queue. The download task with the number of locations is regarded as the current download task, and the current download task is the task that currently needs to be downloaded.

At this time, before determining whether the current download task in the download operation queue includes the target download task, it is necessary to first obtain the number of current idle download locations sent by the downloader; The number determines the current download task from the download operation queue;

Among them, if the current downloader is idle, the current number of idle download locations is the target concurrency number of tasks. The target concurrency number minus the number of tasks currently being executed by the downloader is the current number of idle download locations. The target concurrency number is The maximum number of concurrent downloads of the downloader. This target number of concurrent tasks can be set by the user, or it can be the default configuration of the downloader.

S150. If the current download task includes the target download task, download the target file data corresponding to the target download task through the downloader of the target device.

In this embodiment, if the current download task includes a target download task, it means that the download operation of the target download task currently needs to be performed by the downloader.

Specifically, in some embodiments, the target download task carries a target download address, a target download header, and a target file name, and the target file data corresponding to the target download task is downloaded through the downloader of the target device, include:

Generate a target download request according to the target download address and the target download header; send the target download request to the server through the downloader; receive the target file data returned by the server based on the target download request, and The target file data is stored in a target cache file corresponding to the target file name. The target cache file may be a file in the tmp cache path.

After sending the target download request to the server, the corresponding download task will be deleted from the download operation queue. Specifically, the file download device sends the target download request to the downloader through the http session. The target download request includes the target download address and the request header, the request header is an http header, and the request header includes a range value, which is determined based on the target download header.

In some embodiments, the file download device in the embodiment of the present application also provides a breakpoint resume function for files. If it is found that a file corresponding to the download task already exists by matching the local cache directory, at this time, it means that the file has been downloaded. After passing the download task, if the task is not completely downloaded, the breakpoint resume function will be executed for the task by adjusting the corresponding download interval.

For the target download task, specifically, in some embodiments, before generating a target download request according to the target download address and the target download header, the method further includes:

Detect whether the target file name is included in the local cache directory. The local cache directory includes cache file names corresponding to multiple cache files. The cache files are files that have not been downloaded; if the local cache directory includes the cache file names, If the target file name is specified, the file size of the target cache file corresponding to the target file name is obtained; and the target download header is adjusted according to the file size.

At this time, the target download request is generated based on the adjusted target download header, and the target download task can be resumed at a breakpoint, thereby saving the download traffic of the target download task and improving the download efficiency of the target download task.

For example, the target application requests to download a 1024K file, of which 512K has been downloaded. Due to the network interruption, the target application requests to resume the download. At this time, the target application will also send a target download task to the file download device. At this time, by matching the local It is found that the target cache file corresponding to the target download task already exists in the local cache directory, and the file size of the target cache file is 512K. At this time, the range value of the download header is adjusted from the default "bytes=0" to "bytes= 512000", after the server receives the target download request, it will start transmission from the 512K position of the file, and add: bytes512000-/1024000 to the HTTP header.

If it is found that the size of the target cache file is the size of the target file, then the download completion information will be returned and the download process of the target download task will be ended.

Specifically, in some embodiments, the following steps are used to detect whether the target file name is included in the local cache directory:

Perform hash value conversion processing on the target file name to obtain the target hash value corresponding to the target file name; determine whether there is a cache file name with the same target hash value in the local cache directory; if there is If the cache file name is the same as the target hash value, it is determined that the local cache directory contains the target file name; if there is no cache file name that is the same as the target hash value, it is determined that the local cache The target file name is not included in the directory.

That is, the hash of the file name stored in the local cache directory.

Wherein, after storing the target file data in the target cache file corresponding to the target file name, the method further includes:

Determine whether the target file data has been downloaded according to the file size of the target cache file and the task size corresponding to the target download task; if it is determined that the target file data has been downloaded, convert the target cache file into a target available file, and then returns the target file data, such as the file path and metadata, of the file available to the target to the target application.

Among them, this embodiment converts the target cache file into a target available file by modifying the suffix of the file.

If an exception occurs during the download, the target downloads the target cache file corresponding to the task and returns the exception information.

To sum up, the file download method provided by the embodiment of the present application is applied to the file download device in the target device. After the file download device obtains at least one target download task sent by the target application in the target device, it will download the file according to the preset The priority policy determines the priority of each target download task; and then adds each target download task to the download operation queue of the target device according to the priority of each target download task, and the download operation The download tasks in the queue are arranged in order from high to low priority; for each target download task, it is determined whether the current download task of the download operation queue includes the target download task; if the current download task includes the Target download task, then download the target file data corresponding to the target download task through the downloader of the target device. In the embodiment of this application, before the downloader downloads the task, it will first add the task to the download operation queue according to the priority of the task, and then request the downloader to perform file download in sequence according to the order of tasks in the download operation queue.
