Embodiment Construction
[0029] The following description serves to disclose the present invention to enable those skilled in the relevant art to carry out the present invention. The embodiments in the following description are only examples, and those skilled in the relevant art can conceive of other obvious modifications that fall within the protection scope of the present invention.
[0030] In programming languages, loop nesting is a common method for batch processing instructions, and loop nesting can also be used to generate certain regular strings. First, set the variable for the inner loop, and use the characteristic that the upper and lower limits change with the variable, so that the loop nesting will automatically update the upper and lower limits of the inner loop after executing a loop and enter the next loop, so as to reach the limit of the inner loop. The upper and lower limits follow up the effect of the upper and lower limits according to the outer loop to complete the creation of tas...

The invention discloses a method for scheduling tasks in batches based on a programming language, which includes obtaining access links from target webpages, creating links in batches, analyzing the rules of similar links, creating and executing them in batches through an upper limit following algorithm, and linking the links Store it in the mongoDB database, and update the link in the database through the task execution result. The present invention implements the creation of coroutine tasks in batches through loop nesting, optimizes the memory occupied by the creation of coroutine tasks, effectively reduces the failure of returning results caused by the interruption of coroutine tasks, and causes the loss of business processing and time; Strings are converted and directly stored in the database as KEY values, which effectively shortens the retrieval time of necessary strings required for task processing, thereby improving the stability and efficiency of completing coroutine tasks.
Description
technical field [0001] The invention relates to the technical field of computer software, in particular to a method for scheduling tasks in batches based on a programming language. Background technique [0002] Coroutine is a lightweight thread, and its scheduling switching is faster than multi-threading and multi-process. However, the execution method of the coroutine is to execute the unblocked part of all tasks, and then return the execution results of all tasks uniformly after the unblocked part of all tasks is executed. In the process of coroutine executing tasks, it is necessary to store a specific string in the database first, and then obtain it from the database when needed, and instantiate the coroutine. When the number of strings is large, this process will take up a lot of storage space. Furthermore, when all the non-blocking parts are executed, the execution result is returned, and the execution result is updated to the database by traversal. When the amount o...
