It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for implementing concurrent control of an educational operating system according to a preferred embodiment of the present invention. As shown in fig. 1, it includes the steps of:
s100, acquiring a concurrency threshold value of a page data request;
step S200, acquiring a page data request of a current client, judging whether the concurrency number of the page data request is greater than a concurrency number threshold, if so, executing step S300, and if not, executing step S400;
step S300, pushing the page data request into a standby execution stack;
step S400, pushing the page data request into an execution stack, initiating the request according to the execution stack, and returning the request result to the client.
In specific implementation, more and more project modules are used in the existing education operating system, and sometimes a plurality of concurrent page data requests occur in one page, which easily causes server crash. Therefore, in the embodiment of the present invention, when the page data request of the current client is obtained, the preset concurrency number threshold of the page data request is obtained, so as to obtain the processing state of the current server, if the concurrency number of the page data request is greater than the concurrency number threshold, and if the concurrency number of the page request is greater than the concurrency number threshold, it is indicated that the processing capability of the server cannot process the current page request concurrency number. If the concurrency number of the page requests is smaller than or equal to the concurrency number threshold, the processing capability of the server can process all the current concurrent page requests.
Therefore, when the concurrency number of the page request is detected to be less than or equal to the concurrency number threshold value, the page data request is placed in the execution stack, the processor sequentially takes out the data of the execution stack, executes the data of the execution stack, initiates a request to the server according to the execution stack, and returns a request result to the client.

The method stores data according to a first-in and second-out principle, the first-in data is pressed to the bottom of a stack, the last data is on the top of the stack, and data is popped from the top of the stack when data needs to be read (the last data is read out first). The stack has a memory function, and the stack bottom pointer does not need to be changed in the inserting and deleting operation of the stack.
Further, before obtaining the concurrency threshold of the page data request, the method includes:
the concurrency number threshold of the page data request is set in advance.
In specific implementation, the concurrency number threshold is set in advance, for example, the concurrency number threshold is recorded as maxLimit, and the maxLimit can be set to 5.
Further, if the concurrency number of the request is less than or equal to the concurrency number threshold, pushing the request into an execution stack, initiating the request, and returning a request result to the client, including:
if the request concurrency number is less than or equal to the concurrency number threshold value, counting the current concurrency number, and adding 1 to the value of the current concurrency number;

and acquiring a request result and returning the request result to the client.
In specific implementation, the initial value of the current concurrency number is set to 0 in advance, and a request API of the current client is obtained, where the API (Application Programming Interface) is some predefined functions, and is used for providing the capability of an Application program and a developer to access a set of routines based on certain software or hardware without accessing source codes or understanding details of an internal working mechanism. And judging whether the API is in a callback form, and if the API is requested to be in the callback form, automatically converting the API into a promise form. The Promise object is a message used to pass asynchronous operations. If the request API is not in a callback form, initiating the request API, judging whether the current request concurrency number is greater than a threshold value, counting the current concurrency number if the request concurrency number is less than or equal to the threshold value of the concurrency number, and pushing the request into an execution stack to initiate the request, wherein the request is successful or failed to end; and returning the request result to the client.
In some other embodiments, obtaining the request result and returning the request result to the client comprises:
the client processes the request result;
and acquiring the current concurrency number, and subtracting 1 from the current concurrency number.
In specific implementation, the client processes the request result, counts the current concurrency number, and obtains the executed concurrency number from the current concurrency number-1. .
Further, counting the current concurrency number, and subtracting 1 from the current concurrency number, the method includes:
destroying the page data request and releasing the memory;
judging whether the current concurrency number is larger than a concurrency number threshold value or not;
if the current concurrency number is larger than the concurrency number threshold value, continuing to wait for calling;
and if the current concurrency number is less than or equal to the concurrency number threshold value, taking out the request of the standby execution stack for execution.
In specific implementation, the page data request is destroyed, and the memory is released; continuously judging whether the current concurrency number is larger than a concurrency number threshold value or not;
if the current concurrency number is larger than the concurrency number threshold, continuing to wait for calling until the concurrency number is smaller than or equal to the concurrency number threshold, and executing the request of the standby execution stack;
and if the current concurrency number is less than or equal to the concurrency number threshold value, taking out the request of the standby execution stack for execution.
Further, if the current concurrency number is less than or equal to the concurrency number threshold, the request of the standby execution stack is taken out for execution, including:
if the current concurrency number is less than or equal to the concurrency number threshold value, whether the standby execution stack has a request to be executed or not is inquired;
if the standby execution stack has a request to be executed, taking out the request of the standby execution stack and executing;
and if the standby execution stack has no request to be executed, clearing the information of the two execution stacks and releasing the memory.
In specific implementation, the request is destroyed, the memory is released, whether the current concurrency number is greater than a threshold value is inquired, and if so, the waiting is continued; if not, inquiring whether the standby execution stack has a request to be executed or not, if so, taking out the first request of the standby execution stack, counting the current concurrency number, wherein the value of the current concurrency number is +1, pushing the request into the execution stack, initiating the request, and finishing the request successfully or unsuccessfully; and returning the request result to the client, processing the request result by the client, counting the current concurrency number-1 of the current concurrency number, if not, clearing the information of the two execution stacks, releasing the memory, and finishing.
