Description

Multi-thread segment downloading method, device, client device, electronic device and storage medium Technical field

The present application relates to network download technology, and in particular to a multi-thread segment download method, a multi-thread segment download device, a client device, an electronic device, and a storage medium.

Background technique

With the development of network technology, in many cases, users need to download files from the network.

Multi-threaded segmentation download technology is a very common download solution. In the multi-thread segmentation downloading technique, a file to be downloaded is divided into a plurality of section segments. This technique takes advantage of multithreading by initiating multiple download requests for multiple interval segments through multiple threads during the same time period. Each thread is responsible for downloading one of the multiple interval segments. Then, the data of each interval segment after the download is merged into a complete file. This greatly speeds up the download efficiency. With multi-threaded segmentation download technology, you can grab more bandwidth and achieve faster download speeds.

Common multi-threaded download client devices include Thunder, QQ Cyclone, PP Assistant client and so on. In addition, multi-threaded segment download devices are integrated into many applications such as browsers. For example, users can download files directly from a browser.

In the prior art, the steps of multi-threaded segment downloading are as follows. First, a heuristic request is made to the network to request a download of the file. When a download response is received, the file size is obtained based on the header of the download response. Disconnect the probe request. The file is equally divided into N interval segments based on the file size. A plurality of download requests are respectively initiated for the N interval segments for downloading.

In the prior art solution, if the file is divided into N interval segments, N+1 requests, including a probe request and N download requests, need to be sent. In prior art solutions, the heuristic request is only used to obtain the file size for partitioning the file. Each time you initiate a request to the server, you need to re-establish a TCP connection. The probe request is not used for actual downloads, but it puts pressure on the processing of the server. If multiple download tasks are initiated at the same time, the probe request may add a lot of burden to the server.

For example, in the prior art, the probe request A is initiated and the number of bytes of the file is 600. Next, disconnect the probe request A. Suppose that it takes 5 seconds to send a probe request and receive its response. The file is divided into three interval segments equally, which are [0 to 200], [200 to 400], and [400 to 600]. Three download requests are initiated for the three interval segments, respectively. It is assumed that the time taken to initiate the three download requests is also 5 seconds. Therefore, during the download process, four requests were initiated and the actual download of the data started after 10 seconds.

In addition, in the prior art, it is necessary to wait for the download response of the probe request to obtain the file size before each download task actually starts. After that, a download request can be initiated to begin downloading the file. This means that from the user's click to download to the actual start of the download, an additional request is required, extending the operating time. Suppose the download response of the probe request takes 5 seconds, and it takes 5 seconds to initiate the download request. Then the download is actually started 10 seconds after the user clicks the download. This delays the start of the download and reduces the user's download experience.

Therefore, there is a need to provide a new technical solution for improving at least one of the above-mentioned prior art problems.

<method>

FIG. 1A is a schematic flowchart of a multi-thread segment downloading method according to an embodiment of the present application.

As shown in FIG. 1A, in step S1100, a probe request is initiated. The heuristic request is for requesting to download a file from the network.

The heuristic request can request a complete file. For example, the value of the "range" field in the request header of the probe request is "bytes=0-", which means that the section of the data stream of the requested file is from the 0th byte to the last.

For example, a user sends a heuristic request to a server or device on the network through a client device in the electronic device or a multi-threaded segment download device in the application software. The server or device on the network returns the download response to the user after receiving the request, so that the user can start the download operation.

At step S1200, a download response is received to obtain the size of the file.

For example, based on the prior art scheme, the size of the file can be obtained based on the "content-range" or "content-length" field in the response header of the download response. As the technology evolves, the size of the file can also be obtained based on other fields or information.

In step S1300, the file is divided into a plurality of section segments according to the size of the file. The interval segment in which the probe request is located is the first interval segment. Here, the first interval segment does not indicate that the interval segment is the position of the interval segment, but represents the interval segment in which the trial request is located.

At step S1400, a download request is initiated for other interval segments other than the first interval segment.

In one example, a plurality of interval segments are equally divided, and the plurality of interval segments have the same size. For example, the total number of bytes of a file is 600, and the file is equally divided into three sections, which are [0 to 200], [200 to 400], and [400 to 600], respectively.

Here, the thread in which the probe request is located is not terminated, but continues to be downloaded. For example, when the download amount of the thread reaches the size of the first interval [0 to 200], the thread is disconnected and the download is stopped.

For example, a download request can be initiated for other interval segments [200-400] and [400-600], so the values of the "range" field in the request header of the download request are set to "bytes=200-400" and "bytes", respectively. =400-600" to download the data of the corresponding interval segment.

Moreover, the difference from the prior art is that the embodiment of the present application does not stop the download of the probe request. Therefore, when a download request for another interval segment is initiated, the heuristic request has already downloaded a portion of the data. Since the probe request is disconnected in the prior art, the prior art does not need to be considered for the case where the probe request has downloaded a part of the data. In the embodiment of the present application, considering the case, the size of the first interval segment may be larger than the size of each of the other interval segments.

Further, with the development of network technology, the network speed is getting faster and faster. When other download requests are initiated, a large amount of data may have been downloaded through the heuristic request. If the average segmentation interval is in accordance with the prior art, the advantages of multi-threaded segmentation download may not be fully utilized. For example, when the data of other interval segments is being downloaded, the first interval segment has been downloaded. In addition, if the network speed is fast, when dividing a plurality of interval segments, the amount of data downloaded through the heuristic request has exceeded the size of the first interval segment, which may cause repeated downloading or waste of network resources.

Therefore, the difference between the first interval segment and each of the other segment segments can be set based on the network speed. Thus, for example, in general, the download of the first interval segment can be consistent with the download of other interval segments to be completed simultaneously or substantially simultaneously. For example, based on the network speed prediction, when the download of the other interval segments is started, the difference between the first interval segment and each of the other segment segments is determined by the download amount of the probe request.

Optionally, the difference between the first interval segment and each of the other interval segments may also be set based on the amount of data that has been downloaded by the heuristic request when the download request is initiated.

At step S1500, the data of the first section segment downloaded by the heuristic request and the data of the other section segments are merged into the file.

In the described embodiment, the download process of the probe request is not terminated. This way, the number of times a download request is initiated can be reduced. This can reduce the processing pressure of the server. In addition, this speeds up downloads and improves the user's download experience.
