[0002] With the development of data communication technology, there are more and more scenarios where users interact with servers through browsers. For example, users can download files from servers through browsers. However, when users use browsers to download data, the download task may encounter various interruption scenarios such as long pauses, browser restarts, and special processing logic on the server.

[0107] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0108] One of the core concepts of the embodiments of the present invention is that in an interruption scenario where the download process of the target data is briefly paused, the data receiving window length of the browser and the data sending window length of the server can be adjusted to 0, thereby achieving the effect of pausing the data download. When a trigger operation for resuming the download is detected after a short pause, the data receiving window length of the browser and the data sending window length of the server are restored to the original length, thereby resuming the data download process. In an interruption scenario where the download process of the target data is paused for a long time, the browser can disconnect from the server, and then when a trigger operation for resuming the download is detected, the browser can re-establish a connection with the server, and resume the data download through a resume request, so that after the above interruption scenario occurs, the data download process can be resumed, and the remaining data can be continued to be downloaded on the basis of retaining the original downloaded content.

[0109] Reference Figure 1 , shows a flowchart of a method for downloading data based on a browser according to an embodiment of the present invention, the method for downloading data is applied to a system including a browser and a server, and may specifically include the following steps:

[0110] Step 101: When the browser detects a trigger operation for pausing downloading during the process of downloading target data from the server, the browser adjusts the length of the data receiving window from a first initial length to 0 and starts timing; sends a first response message to the server; the first response message carries information that the length of the data receiving window is 0.

[0111] In the embodiment of the present invention, a TCP (Transmission Control Protocol) connection can be established between the browser and the server. TCP is a connection-oriented, reliable, byte-stream-based transport layer communication protocol defined by IETF RFC 793. When the application layer sends a data stream represented by 8-bit bytes for Internet transmission to the TCP layer, the TCP layer divides the data stream into segments of appropriate lengths. The maximum transmission segment size (MSS) is usually limited by the maximum transmission unit (MTU) of the data link layer of the network to which the computer is connected. The TCP layer then passes the data packet to the IP layer, which transmits the data packet to the TCP layer of the receiving entity through the network.

[0112] In order to ensure the reliability of message transmission, TCP gives each data packet a sequence number, which also ensures that the data packets transmitted to the receiving entity are received in order. The receiving entity then sends back a corresponding confirmation (ACK) for the bytes that have been successfully received. If the sending entity does not receive an acknowledgment for a data packet within a reasonable round-trip time (RTT), the data (considered to be lost) will be retransmitted.

[0113] There is a Window Size field in the TCP message header, which refers to the window of the receiving end, that is, the data receiving window, which is used to inform the sending end of the amount of data it can receive, thereby achieving a part of the flow control purpose. During the entire data transmission process, TCP also measures the current network status in order to maintain a healthy and stable transmission process. Therefore, data is transmitted under the control of certain mechanisms, which is the window mechanism.

[0114] For the sender of a TCP session, the data in its send buffer at any time can be divided into four categories, including "sent and received ACK from the other end", "sent but not received ACK from the other end", "not sent but allowed by the other end", and "not sent and not allowed by the other end". Among them, "sent but not received ACK from the other end" and "not sent but allowed by the other end" can be called the data sending window.

[0115] TCP is a duplex protocol. Both parties in a session can send and receive data. Both parties in a TCP session maintain a data send window and a data receive window. The length of the data receive window depends on the limitations of the application, system, and hardware (the TCP transmission rate cannot be greater than the data processing rate of the application), and the requirements for the data send window depend on the data receive window announced by the other end.

[0116] It should be noted that, in the embodiment of the present invention, for a data download process, the browser is the data receiver and the server is the data sender. Therefore, the data receiving window mentioned in the embodiment of the present invention refers to the data receiving window of the browser, and the data sending window mentioned in the embodiment of the present invention refers to the data sending window of the server.

[0117] In an embodiment of the present invention, when a browser needs to download target data from a server, the browser can establish a TCP connection with the server and send a download request for the target data to the server. When the server receives the download request, it can respond and start sending the target data, thereby starting the download process of the target data. In the process of the browser downloading the target data from the server, when the browser detects a trigger operation for pausing the download, for example, when the user clicks the pause icon of the target data download progress in the browser interface, the browser can adjust the length of its own data receiving window from the current first initial length to 0, and start a timer to start timing. At the same time, the browser can also send a first response message to the server to inform the server of the information that the length of the data receiving window is adjusted to 0.

[0118] Wherein, the download request of the target data can be an HTTP (Hypertext Transfer Protocol) request. HTTP is a simple request-response protocol, which usually runs on the basis of TCP connection. It specifies the request sent by the browser to the server and the response returned by the server to the browser. The header of the request and response message is given in ASCII code, and the message content has a format similar to MIME (Multipurpose Internet Mail Extensions). The HTTP protocol communicates based on the B / S (Browser / Server) architecture. The implementation programs of the server using the HTTP protocol include httpd, nginx, etc. The implementation programs of the browser using the HTTP protocol are mainly Web browsers, such as Firefox, Google, chrome, Safari, Opera, etc. Optionally, in an embodiment of the present invention, the server can be a browser server, or a third-party server corresponding to the third-party data requested by the browser. For example, when the third-party data requested by the browser is video data, the server is a third-party video server.

[0119] Step 102: When the server receives the first response message, it adjusts the length of the data sending window from the second initial length to 0 to suspend downloading.

[0120] In this step, when the server receives the first response message sent by the browser, it can be determined that the length of the current data receiving window is adjusted to 0, and then the server can adjust the length of its own data sending window from the current second initial length to 0. So far, the lengths of the data sending window and the data receiving window are both 0, the server cannot send data, and the browser cannot receive data, so the download process is suspended.

[0121] Step 103: When the browser detects a trigger operation for resuming downloading and the timing duration does not exceed the preset duration, the browser stops timing and restores the length of the data receiving window to the first initial length; and sends a second response message to the server; the second response message carries the information that the length of the data receiving window is the first initial length.

[0122] In this step, if the timing duration does not exceed the preset duration, a trigger operation for resuming downloading is detected, that is, the download task is suspended for a short time and then resumed. In this case, the browser can stop timing and restore the length of the data receiving window from 0 to the original first initial length. At the same time, the browser can also send a second response message to the server to inform the server of the information that the length of the data receiving window is restored to the first initial length.

[0123] The trigger operation for resuming downloading may be, for example, a click operation performed by the user on a continue downloading icon of the target data download progress in the browser interface.

[0124] In a standard protocol, data is encapsulated into data packets according to a certain byte length when being sent. Therefore, in the embodiment of the present invention, the first initial length and the second initial length may both refer to the number of data packets.

[0125] Step 104: When the server receives the second response message, it restores the length of the data sending window to the second initial length to resume downloading.

[0126] In this step, when the server receives the second response message sent by the browser, it can be determined that the length of the current data receiving window is restored to the first initial length, and then the server can restore the length of its own data sending window from 0 to the original second initial length. At this point, the lengths of the data sending window and the data receiving window are restored to their original lengths, the server can continue to send data, and the browser can also continue to receive data, so the download process is restored.

[0127] In existing applications, some browsers will actively disconnect from the server when the data download process is paused for a short time. If the user manually resumes the download later, the browser will reconnect with the server to continue the download process. For some servers, the URL (Uniform Resource Locator) address, that is, the download address, provided by the server is the same after the connection is reestablished and before the connection is disconnected for the same downloaded data. Therefore, by adopting the above method, the download can be continued after reconnecting to the server. However, some servers have special processing logic. For example, some servers reallocate URL addresses according to different connections. In this way, if the above method is adopted, the original download task cannot be continued after reconnecting to the server, because the URL address of the downloaded data has changed after reconnecting. In this case, the browser can only restart the download according to the new URL address, but cannot continue the download from the original progress, thereby causing the original download task to fail and increasing the download time.

[0128] In an embodiment of the present invention, when the data download process is briefly paused, the effect of pausing the data download can be achieved by adjusting the data receiving window length of the browser and the data sending window length of the server to 0, so that the browser does not need to disconnect from the server. In this way, when the download process is resumed, the URL address of the downloaded data will not change. Therefore, the remaining data can be continued to be downloaded from the original progress, thereby being compatible with the server with special processing logic for the URL address change after reconnection, and being able to ensure that the download task can be successfully resumed in the scenario of a short pause, and the remaining data can be incrementally downloaded on the basis of retaining the original downloaded content.

[0129] Step 105: When the timing duration exceeds the preset duration, the browser disconnects from the server; when the trigger operation for resuming downloading is detected, the browser re-establishes the connection with the server; and sends a resume request to the server; the resume request is used to request the server to send the remaining data in the target data to the browser to resume downloading.

[0130] In this step, when the timing duration exceeds the preset duration, that is, when the download task is suspended for a long time, the browser can actively send a RST (reset) packet to the server, thereby actively disconnecting from the server. Afterwards, when a trigger operation for resuming the download is detected, the browser can re-establish a connection with the server and send a resume request to the server to request the remaining data.

[0131] In an embodiment of the present invention, when the data download process is paused for a long time, the browser can actively disconnect from the server, and then re-establish the connection with the server when it is necessary to continue downloading, and request the remaining data from the server through a resume request. In this way, after the data download process is paused for a long time, the data download process can be resumed, and the remaining data can be incrementally downloaded on the basis of retaining the original downloaded content.

[0132] Step 106: When the server receives the resume request, it sends the remaining data in the target data to the browser to resume downloading.

[0133] Optionally, this step can be implemented in the following ways:

[0134] When the server receives the resume request, the server sends a resume response message to the browser; the resume response message is used to indicate that the server will send the remaining data in the target data to the browser;

[0135] The server sends the remaining data in the target data to the browser to resume downloading.

[0136] Optionally, the retransmission request may be an HTTP request, and the retransmission request may include a Range field, where the Range field includes a receivable data range in the remaining data.

[0137] Optionally, the resume response message may be an HTTP request, and the resume response message may include a Content-Range field, and the Content-Range field includes a data range that can be sent in the remaining data and a data amount of the remaining data.

[0138] In actual applications, the HTTP 1.1 protocol can support obtaining partial content of a file. This function can be implemented through two parameters in the header. When the browser sends a request, it carries the Range field in the header to specify the location of the first byte and the last byte of the requested data in the file. After receiving a resume request carrying the Range field, the server can carry the Content-Range field in the resume response to return the current data range that can be returned and the total size of the remaining data. Among them, the header content of the resume response message can be HTTP / 1.1 206Partial Content, indicating the use of breakpoint resume mode.

[0139] Further optionally, the method may further include the following steps:

[0140] When the browser completes the restart and the timing duration does not exceed the preset duration, the browser re-establishes a connection with the server;

[0141] The browser sends the resume request to the server.

[0142] Among them, when the timing duration does not exceed the preset duration, that is, when the download task is suspended for a short time, when the browser restarts and completes the restart, the browser can re-establish a connection with the server and send a resume request carrying the Range field to the server. In this way, when the browser restarts during the pause of the data download process, the download can be resumed, and the remaining data can be incrementally downloaded on the basis of retaining the original downloaded content.

[0143] Further optionally, the method may further include the following steps:

[0144] The browser re-establishes a connection with the server when the browser completes the restart during the process of downloading the target data from the server;

[0145] The browser sends the resume request to the server.

[0146] Among them, during the process of downloading the target data on the server side, that is, during the execution of the download task, when the browser restarts and completes the restart, the browser can re-establish the connection with the server and send a resume request carrying the Range field to the server, so that during the data download process, if the browser restarts, the download can be resumed, and the remaining data can be incrementally downloaded on the basis of retaining the original downloaded content.

[0147] In an embodiment of the present invention, in an interruption scenario where the download process of the target data is briefly paused, the data receiving window length of the browser and the data sending window length of the server can be adjusted to 0, thereby achieving the effect of pausing the data download. When a trigger operation for resuming the download is detected after a short pause, the data receiving window length of the browser and the data sending window length of the server are restored to the original length, thereby resuming the data download process. In an interruption scenario where the download process of the target data is paused for a long time, the browser is restarted during the pause of the data download process, and the browser is restarted during the data download process, the browser can re-establish a connection with the server and resume the data download through a resume request, so that after the above interruption scenario occurs, the data download process can be resumed, and the remaining data can be continued to be downloaded on the basis of retaining the original downloaded content, thereby improving the success rate of data download.

[0148] Reference Figure 2 , shows a flowchart of another embodiment of a data download method based on a browser of the present invention. The data download method is applied to a browser and may specifically include the following steps:

[0149] Step 201: in the process of downloading target data from a server, when a trigger operation for pausing downloading is detected, the length of the data receiving window is adjusted from a first initial length to 0, and timing is started;

[0150] Step 202: Send a first response message to the server, so that when the server receives the first response message, it adjusts the length of the data sending window from the second initial length to 0 to suspend downloading; the first response message carries information that the length of the data receiving window is 0;

[0151] Step 203: When the timing duration does not exceed the preset duration and a trigger operation for resuming downloading is detected, the timing is stopped and the length of the data receiving window is restored to the first initial length;

[0152] Step 204: Send a second response message to the server, so that when the server receives the second response message, it restores the length of the data sending window to the second initial length to resume downloading; the second response message carries information that the length of the data receiving window is the first initial length;

[0153] Step 205: When the timing duration exceeds the preset duration, disconnecting from the server;

[0154] Step 206: When the trigger operation for resuming downloading is detected, re-establishing a connection with the server;

[0155] Step 207: Send a resume request to the server to resume downloading; the resume request is used to request the server to send the remaining data in the target data to the browser.

[0162] Optionally, the resume request is an HTTP request, and the resume request includes a Range field, and the Range field includes a receivable data range in the remaining data.

[0163] In one embodiment, the preset duration is shorter than the first duration set by the server, and when the server stops transmitting for more than the first duration, the server will actively disconnect from the browser. In this embodiment, before the browser pauses data downloading and the server actively disconnects from the browser, the browser actively disconnects from the server to ensure the preservation of the current download information for the necessary information contained in the subsequent generation of the resume request.

[0164] In an embodiment of the present invention, in an interruption scenario where the download process of the target data is briefly paused, the data receiving window length of the browser and the data sending window length of the server can be adjusted to 0, thereby achieving the effect of pausing the data download.
