本发明的实施方式Embodiments of the invention
以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、技术之类的具体细节，以便透彻理解本申请实施例。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施例中也可以实现本申请。在其它情况中，省略对众所周知的系统、装置、电路以及方法的详细说明，以免不必要的细节妨碍本申请的描述。In the following description, for purposes of illustration and description However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the application.
为了说明本申请所述的技术方案，下面通过具体实施例来进行说明。In order to explain the technical solutions described in the present application, the following description will be made by way of specific embodiments.
请参阅图1，本申请实施例中一种下载请求处理方法第一个实施例包括：Referring to FIG. 1, a first embodiment of a download request processing method in an embodiment of the present application includes:
101、接收终端发起的下载请求；101. Receive a download request initiated by the terminal.
本实施例中，当用户需要下载某个文件时，可以通过终端向服务器发起该文件的下载请求，从而服务器可以接收到该下载请求。In this embodiment, when the user needs to download a certain file, the terminal may initiate a download request of the file to the server, so that the server can receive the download request.
102、判断所述下载请求所需的下载文件的大小是否超过预设阈值，若否，则执行步骤103，若是，则执行步骤104；102, determining whether the size of the download file required for the download request exceeds a preset threshold, if not, proceed to step 103, and if so, proceed to step 104;
可以理解的是，由于共享在服务器中的文件的数据量往往非常庞大，因此，这些文件通常是存储在与服务器连接的数据库中。在服务器根据该下载请求下载文件时，服务器需要先从对应数据库中下载该文件，然后将该文件发送给用户终端。因此，当文件较大时，服务器往往等待较长的时间才能完成该文件的下载。As can be appreciated, since the amount of data shared by files in the server is often very large, these files are usually stored in a database connected to the server. When the server downloads a file according to the download request, the server needs to first download the file from the corresponding database, and then send the file to the user terminal. Therefore, when the file is large, the server often waits for a long time to complete the download of the file.
本实施例中，通过判断该下载请求所需的下载文件的大小是否超过预设阈值，若否，则表示服务器可以在较短的时间内完成该下载文件的下载，从而执行步骤103，下载该文件然后通过当前会话链接交给用户的终端；若是，则表示服务器需要消耗较长的时间才能完成该下载文件的下载，从而执行步骤104及后续步骤，通过后台的方式完成文件的下载。In this embodiment, it is determined whether the size of the download file required by the download request exceeds a preset threshold. If not, it indicates that the server can complete the download of the downloaded file in a short time, thereby performing step 103, downloading the The file is then delivered to the user's terminal through the current session link; if so, it means that the server needs to take a long time to complete the download of the downloaded file, thereby performing step 104 and subsequent steps to complete the file download in the background manner.
103、保持与所述终端之间的当前会话链接，在下载完成所述下载文件之后，将所述下载文件通过所述当前会话链接发送至所述终端；103. Maintain a current session link with the terminal, and after downloading the download file, send the download file to the terminal by using the current session link;
当该下载文件较小时，服务器可以在短时间内完成下载文件的下载从而交给用户的终端，因此，服务器可以保持与所述终端之间的当前会话链接，直至下载文件完成后再释放。When the download file is small, the server can complete the download of the download file in a short time and hand it to the user's terminal. Therefore, the server can maintain the current session link with the terminal until the download file is completed and then released.
104、释放服务器与所述终端之间的当前会话链接；104. Release a current session link between the server and the terminal.
本实施例中，为避免当前会话链接长期占用服务器的会话链接资源，在判定所述下载请求所需的下载文件的大小超过预设阈值时，可以释放服务器与所述终端之间的当前会话链接。In this embodiment, in order to prevent the current session link from occupying the session link resource of the server for a long time, when determining that the size of the download file required for the download request exceeds a preset threshold, the current session link between the server and the terminal may be released. .
进一步地，在释放服务器与所述终端之间的当前会话链接之前，服务器还可以请求所述终端设定后台下载所述下载文件的执行时段。可以理解的是，服务器在日常使用中，存在忙时和闲时，在忙时，服务器的内存资源较为紧缺，不利于用于下载大体积的文件；而在闲时，服务器的内容资源往往较为空间，例如在半夜时段，服务器在闲时时段下载大体积的文件则更为合适。因此，在判定述下载请求所需的下载文件的大小超过预设阈值之后，服务器可以先询问用户的终端，请求用户设定一个执行时段，服务器将在设定的该执行时段建立后台线程来完成下载文件的下载。进一步地，在下述步骤105之前，若服务器获取到所述终端设定的所述执行时段，则当所述服务器的当前系统时间到达所述执行时段时，执行下述步骤105。Further, before releasing the current session link between the server and the terminal, the server may further request the terminal to set an execution period in which the download file is downloaded in the background. Understandably, in daily use, the server has busy time and idle time. When busy, the memory resources of the server are scarce, which is not conducive to downloading large files; while in idle time, the content resources of the server are often relatively small. Space, for example, in the middle of the night, it is more appropriate for the server to download large files during free time. Therefore, after determining that the size of the download file required for the download request exceeds a preset threshold, the server may first query the user's terminal, requesting the user to set an execution period, and the server will establish a background thread in the set execution period to complete. Download the download file. Further, before the step 105 is performed, if the server acquires the execution period set by the terminal, when the current system time of the server reaches the execution period, the following step 105 is performed.
105、在所述服务器上建立下载所述下载文件的后台线程；105. Establish a background thread for downloading the download file on the server.
106、通过所述后台线程下载并缓存所述下载文件；106. Download and cache the download file by using the background thread.
对于步骤105和106，服务器可以在合适的时间段建立后台线程，然后通过该后台线程完成下载文件的下载，并将下载好的文件缓存在服务器上，以便于用户的终端与服务器再次建立会话链接之后，可以快速地获取到该下载文件。For steps 105 and 106, the server may establish a background thread at a suitable time period, then complete the download of the downloaded file through the background thread, and cache the downloaded file on the server, so that the user's terminal establishes a session link with the server again. After that, the download file can be quickly obtained.
107、将已下载完成的消息通知给所述终端，以使所述终端重新建立与所述服务器之间的新的会话链接并获取所述缓存中的所述下载文件。107. Notifying the terminal that the downloaded message is completed, so that the terminal re-establishes a new session link with the server and acquires the downloaded file in the cache.
本实施例中，当服务器通过后台线程完成下载文件的下载之后，服务器可以通过邮件、短信、系统消息等方式通知终端，用户在得知该通知消息之后，可以选择在任意时候再次登录服务器，终端与服务器重新建立新的会话链接，然后获取服务器缓存中的所述下载文件。In this embodiment, after the server completes the download of the downloaded file through the background thread, the server may notify the terminal by means of mail, short message, system message, etc., after the user knows the notification message, the user may choose to log in to the server again at any time. Re-establish a new session link with the server and then get the download file in the server cache.
另外，在本实施例中，若服务器通过后台线程下载该下载文件失败，例如服务器需求的文件来自某个服务器B，但用户没有获取该服务器B的数据的权限，从而导致下载失败。此时，服务器可以向用户的终端返回相关的失败信息。In addition, in this embodiment, if the server fails to download the downloaded file through the background thread, for example, the file requested by the server is from a certain server B, but the user does not have the right to acquire the data of the server B, thereby causing the download to fail. At this point, the server can return relevant failure information to the user's terminal.
本实施例中，首先，接收终端发起的下载请求；然后，判断所述下载请求所需的下载文件的大小是否超过预设阈值；若所述下载请求所需的下载文件的大小超过预设阈值，则释放服务器与所述终端之间的当前会话链接；接着，在所述服务器上建立下载所述下载文件的后台线程；通过所述后台线程下载并缓存所述下载文件；最后，将已下载完成的消息通知给所述终端，以使所述终端重新建立与所述服务器之间的新的会话链接并获取所述缓存中的所述下载文件。这样，当终端请求下载的文件过大时，服务器可以释放与终端的会话链接，然后通过建立后台线程的方式下载并缓存终端请求的文件，由于请求的文件已缓存，终端可以在合适的时候从缓存中快速获取到该文件，不仅避免了服务器会话链接资源的长时间占用，而且提高了终端获取所请求的文件的效率。In this embodiment, first, receiving a download request initiated by the terminal; and then determining whether the size of the download file required by the download request exceeds a preset threshold; if the size of the download file required by the download request exceeds a preset threshold And releasing a current session link between the server and the terminal; then, establishing a background thread for downloading the download file on the server; downloading and caching the download file by the background thread; and finally, downloading The completed message is notified to the terminal to cause the terminal to re-establish a new session link with the server and obtain the download file in the cache. In this way, when the file requested by the terminal is too large, the server may release the session link with the terminal, and then download and cache the file requested by the terminal by establishing a background thread. Since the requested file is cached, the terminal may at the appropriate time Quickly obtaining the file in the cache not only avoids the long-term occupation of the server session link resource, but also improves the efficiency of the terminal acquiring the requested file.
请参阅图2，本申请实施例中一种下载请求处理方法第二个实施例包括：Referring to FIG. 2, a second embodiment of a download request processing method in the embodiment of the present application includes:
201、接收终端发起的下载请求；201. Receive a download request initiated by the terminal.
202、判断所述下载请求所需的下载文件的大小是否超过预设阈值，若否，则执行步骤203，若是，则执行步骤204；202, determining whether the size of the download file required for the download request exceeds a preset threshold, if not, proceed to step 203, and if so, proceed to step 204;
203、保持与所述终端之间的当前会话链接，在下载完成所述下载文件之后，将所述下载文件通过所述当前会话链接发送至所述终端；203. Keep a current session link with the terminal, and after downloading the download file, send the download file to the terminal by using the current session link.
204、释放服务器与所述终端之间的当前会话链接；204. Release a current session link between the server and the terminal.
上述步骤201~204与第一个实施例中的步骤101~104类似，此处不再赘述。The above steps 201 to 204 are similar to the steps 101 to 104 in the first embodiment, and are not described herein again.
205、根据所述下载请求新建对应的待处理的下载任务；205. Create a corresponding download task to be processed according to the download request.
本实施例中，服务器在释放当前会话链接之后，可以为该下载请求新建一个待处理的下载任务，并在合适的时候执行并完成该下载任务。In this embodiment, after the server releases the current session link, the server may create a new download task to be processed for the download request, and execute and complete the download task when appropriate.
206、获取所述服务器当前可用的内存量；206. Obtain a quantity of memory currently available to the server;
207、确定所述待处理的下载任务中预计内存使用量小于或等于所述当前可用的内存量的下载任务为可执行下载任务；207. Determine that the download task whose estimated memory usage in the to-be-processed download task is less than or equal to the currently available memory amount is an executable download task.
对于步骤206和207，可以理解的是，为了利用服务器的空闲资源来处理这些下载任务，首先需要获取服务器当前可用的内存量有多少，也即空闲的资源有多少。然后，确定这些待处理的下载任务中是否有可执行的下载任务。为此，服务器可以预先统计各种类型的下载任务在运行期间的最大内存使用量M1，从而可以估算出这些待处理的下载任务的预计内存使用量。假设某个待处理的下载任务的类型为A，服务器统计的类型为A的下载任务的最大内存使用量为M1，则该待处理的下载任务的预计内存使用量也为M1。For steps 206 and 207, it can be understood that in order to utilize the idle resources of the server to process these download tasks, it is first necessary to obtain the amount of memory currently available to the server, that is, how much free resources there are. Then, determine if there are executable download tasks in these pending download tasks. To this end, the server can pre-count the maximum memory usage M1 of various types of download tasks during operation, so that the estimated memory usage of these pending download tasks can be estimated. Assuming that the type of the download task to be processed is A, and the maximum memory usage of the download task of the server type A is M1, the estimated memory usage of the pending download task is also M1.
因此，假设服务器当前可用的内存量为M0，则可以将那些M1≤M0的下载任务确定为可执行下载任务。Therefore, assuming that the amount of memory currently available to the server is M0, those download tasks of M1 ≤ M0 can be determined as executable download tasks.
208、判断所述可执行下载任务的数量是否超过预设的数量阈值，若是，则执行步骤209，若否，则执行步骤211；208, it is determined whether the number of executable download tasks exceeds a preset number threshold, and if so, step 209 is performed, and if not, step 211 is performed;
具体地，该数量阈值可以设为1，即，当所述可执行下载任务的数量超过1个时，即2个以上时，执行步骤209；反之，所述可执行下载任务的数量为1时，则执行步骤211。Specifically, the number threshold may be set to 1, that is, when the number of the executable download tasks exceeds one, that is, two or more, step 209 is performed; otherwise, the number of executable download tasks is one. Then, step 211 is performed.
209、计算各个所述可执行下载任务的优先级；209. Calculate a priority of each of the executable download tasks.
若所述可执行下载任务的数量超过预设的数量阈值，则可以计算各个所述可执行下载任务的优先级。可以理解的是，当服务器中可执行的下载任务超过1个时，对服务器来说，按照何种顺序处理这些下载任务将关系到服务器的资源利用率和处理效率。因此，面对多个可执行下载任务时，可以先计算出各个可执行下载任务的优先级，然后按照优先级的先后顺序处理这些可执行下载任务，以便实现服务器资源的最大化利用。If the number of executable download tasks exceeds a preset number threshold, the priority of each of the executable download tasks may be calculated. It can be understood that when more than one download task can be executed in the server, processing the download tasks in the order of the server will affect the resource utilization and processing efficiency of the server. Therefore, in the face of multiple executable download tasks, the priority of each executable download task can be calculated first, and then these executable download tasks are processed in order of priority, so as to maximize the utilization of server resources.
进一步地，如图3所示，步骤209可以包括：Further, as shown in FIG. 3, step 209 may include:
301、获取所述可执行下载任务对应下载请求的第一重要性数值，所述第一重要性数值由所述终端在发起下载请求之前预先设定；301. Obtain a first importance value corresponding to the download request of the executable download task, where the first importance value is preset by the terminal before initiating a download request.
302、根据所述第一重要性数值和预设的第一权重计算所述可执行下载任务的第一优先值；302. Calculate, according to the first importance value and the preset first weight, a first priority value of the executable download task.
303、根据所述可执行下载任务的预估消耗时长和预设的第二权重计算所述可执行下载任务的第二优先值；303. Calculate, according to the estimated consumption duration of the executable download task and the preset second weight, a second priority value of the executable download task.
304、根据各个所述可执行下载任务的第一优先值和第二优先值确定各个所述可执行下载任务的优先级，其中，第一优先值与所述优先级正相关，所述第二优先值与所述优先级负相关。304. Determine, according to the first priority value and the second priority value of each of the executable download tasks, a priority of each of the executable download tasks, where the first priority value is positively related to the priority, and the second The priority value is inversely related to the priority.
对于上述步骤301~304，对于每个下载任务，用户可以预先设定其第一重要性数值，假设为p，另外，服务器可以赋予第一重要性数值p对应的第一权重Vp。从而，该可执行下载任务的第一优先值可以为p*Vp。For the above steps 301-304, for each download task, the user can preset its first importance value, assuming p, and the server can assign the first weight Vp corresponding to the first importance value p. Thus, the first priority value of the executable download task can be p*Vp.
另外，服务器可以预先统计各种类型的下载任务执行所需的耗时T1，从而可以估算出这些可执行下载任务的预估消耗时长t。假设某个可执行下载任务的类型为B，服务器统计的类型为B的下载任务的所需的耗时为T1，则该可执行下载任务的预估消耗时长t=T1。并且，服务器可以赋予所述可执行下载任务的预估消耗时长对应的第二权重Vt，从而该可执行下载任务的第二优先值可以为t*Vt。In addition, the server can pre-count the time consuming T1 required for various types of download tasks to perform, so that the estimated consumption time t of these executable download tasks can be estimated. Assuming that the type of an executable download task is B, and the time required for the download task of the server type B is T1, the estimated consumption time of the executable download task is t=T1. Moreover, the server may assign a second weight Vt corresponding to the estimated consumption duration of the executable download task, so that the second priority value of the executable download task may be t*Vt.
从而，对于一个可执行下载任务来说，其优先级可以由（p*Vp）/（t*Vt）来确定。在计算出所各个所述可执行下载任务的（p*Vp）/（t*Vt）之后，可以根据它们值的大小确定出各个可执行下载任务优先级。可知，对于（p*Vp）/（t*Vt）来说，p*Vp越大，则其值越大，优先级越高；t*Vt越大，则其值越小，优先级越低。Thus, for an executable download task, its priority can be determined by (p*Vp)/(t*Vt). After calculating (p*Vp)/(t*Vt) of each of the executable download tasks, the respective executable download task priorities can be determined according to the size of their values. It can be seen that for (p*Vp)/(t*Vt), the larger the p*Vp, the larger the value and the higher the priority; the larger the t*Vt, the smaller the value and the lower the priority. .
210、根据优先级的先后顺序依次对各个所述可执行下载任务执行步骤211；Step 210: Perform step 211 on each of the executable download tasks in order of priority;
211、在所述服务器上建立当前执行的所述可执行下载任务的后台线程；211. Establish a background thread of the currently executable executable download task on the server.
本实施例中，当所述可执行下载任务的数量未超过预设的数量阈值时，可以直接执行步骤211，若这些可执行下载任务的数量超过1个，服务器可以为这些可执行下载任务设定默认的执行顺序。例如，按照各个可执行下载任务的建立时间的先后顺序，或者按照各个可执行下载任务对应下载的下载文件从大到小或从小到大的顺序，等等。而当所述可执行下载任务的数量超过预设的数量阈值时，则可以按照上述步骤209确定出的优先级的先后顺序依次执行这些可执行下载任务。In this embodiment, when the number of the executable download tasks does not exceed the preset number threshold, step 211 may be directly performed. If the number of the executable download tasks exceeds one, the server may set the executable download tasks. The default execution order. For example, in the order of the establishment time of each executable download task, or in accordance with the order in which the download files corresponding to each executable download task are downloaded from large to small or from small to large, and the like. When the number of executable download tasks exceeds a preset number threshold, the executable download tasks may be sequentially executed in the order of priority determined in step 209 above.
对于步骤211，服务器可以按顺序依次处理这些可执行下载任务，在处理之前，先为当前执行的所述可执行下载任务建立对应的后台线程。进一步地，如图4所示，在每建立一个所述后台线程之后，还包括如下处理步骤：For step 211, the server may process the executable download tasks in sequence, and before processing, first establish a corresponding background thread for the currently executed executable download task. Further, as shown in FIG. 4, after each of the background threads is established, the following processing steps are further included:
401、获取所述服务器当前可用的内存量；401. Obtain a quantity of memory currently available to the server.
402、判断下一个执行的所述可执行下载任务的预计内存使用量是否超过所述当前可用的内存量，若是，则执行步骤207，若否，则执行步骤403；402, determining whether the expected memory usage of the executable download task that is executed next time exceeds the currently available memory amount, and if yes, executing step 207, if not, executing step 403;
403、继续建立下一个可执行下载任务的后台线程。403. Continue to establish the next background thread for the executable download task.
对于步骤401~403，可以每建立一个所述后台线程，服务器上的当前可用的内存量就会发生变化，在不考虑其它占用内存资源的任务的情况下，当前可用的内存量会变小，此时，可能出现剩下的可用内存量不足以处理下一个可执行下载任务的情况。因此，需要执行步骤402进行判断，若判断结果为否，则表示服务器还可以继续处理下一个可执行的下载任务；若判断结果为是，则应该返回执行步骤207，重新确定可执行下载任务。For steps 401 to 403, each of the background threads can be created, and the amount of currently available memory on the server changes. The amount of currently available memory becomes smaller without considering other tasks that occupy memory resources. At this point, there may be situations where the amount of free memory remaining is not enough to handle the next executable download task. Therefore, step 402 is required to perform the determination. If the determination result is no, it indicates that the server can continue to process the next executable download task; if the determination result is yes, then the process should return to step 207 to re-determine the executable download task.
212、通过所述后台线程下载并缓存所述下载文件；212. Download and cache the download file by using the background thread.
213、将已下载完成的消息通知给所述终端，以使所述终端重新建立与所述服务器之间的新的会话链接并获取所述缓存中的所述下载文件。213. Notify the terminal that the downloaded message is complete, so that the terminal re-establishes a new session link with the server and acquires the downloaded file in the cache.
上述步骤212和步骤213分别与第一个实施例中的步骤106和107类似，此处不再赘述。The above steps 212 and 213 are similar to the steps 106 and 107 in the first embodiment, respectively, and are not described herein again.
