It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.

As shown in fig. 1, an embodiment of the present invention provides a Web request processing method applied to a Wi-Fi chip capable of configuring Wi-Fi parameters, where the method includes:

s110, receiving a Web request, and establishing connection for the Web request; the Wi-Fi chip in the embodiment of the invention, such as an ESP8266 chip, is divided into two operation modes, namely a configuration mode and a working mode, and the two modes are switched by a switch. The device is first used to enter a configuration mode by placing the switch in an on state. The execution logic of the configuration mode is to initialize the WI-FI module of the device, set it to AP mode, and then turn on the WEB service, which can process the HTTP request. The client accesses the WI-FI network of the device and accesses the Web service through the browser. The Web server monitors and processes the http request, and returns the processed result to the client. The configuration mode supports configuration of Wi-Fi information and cloud server information. After the configuration is completed, the switch is set to be closed, and the equipment can be restarted to enter the working mode. In the working mode, the device is firstly connected with Wi-Fi, then the device is calibrated, then the cloud server is connected, and the device starts to transmit data after the work is completed. The workflow is shown in fig. 2.

S120, remotely calling the LUA script, and selecting a processing function corresponding to the Web request for processing; and analyzing according to the Web request to acquire a corresponding processing function, and performing data processing, such as data query, data calculation, data packaging and the like, to form a processing result.

S130, returning processing result data; after the processing result is obtained, data packaging and sending are carried out according to the adopted data protocol, for example, the data is sent in an http protocol mode.

In the embodiment of the invention, a Wi-Fi chip is adopted to build a server function, and because the Wi-Fi chip can be limited by a Web service framework which is not mature, in order to meet the requirement of providing Web services, a set of Web service framework is realized based on a LUA base library. The LUA is a lightweight and compact scripting language, and the Wi-Fi chip can bear the functions of the scripting language to run, and the server function is realized by remotely calling the LUA script.

The key technology of the Web server comprises the steps of creating a TCP server, capturing http (hypertext transfer protocol) requests, establishing a connection, analyzing and processing request data, returning a result to a client in an http form, and closing the connection. The method and the device mainly realize analysis and processing of the http request data. The implementation can be characterized by the following according to the selection:

1) And supporting various request modes, including get, post, put and the like, and analyzing according to different Web request modes.

2) Supporting http access authentication;

3) Remotely calling the LUA script in an http mode;

4) Support multiple request encodings;

5) A scenario in which a single request returns a large amount of data can be handled correctly.

In the embodiment of the invention, the LUA script is called remotely, and the step of selecting the processing function corresponding to the Web request for processing comprises the following steps:

triggering a receive event, analyzing request data, acquiring a LUA file name, loading a file to acquire a LUA function, executing the LUA function, triggering a send event, and sending a result acquired by executing the LUA function.

In the embodiment of the present invention, the step of loading the file to obtain the LUA function includes:

loading files in a dofile mode to obtain the LUA function

In order to realize the scene of processing larger data volume in the Wi-Fi chip with limited performance, the method for processing the Web request in the implementation of the invention adopts a collaborative program to process, thereby reducing the requirement on the performance of equipment and simultaneously avoiding data transmission errors. Specifically, the step of selecting a processing function corresponding to the Web request for processing includes: creating a collaborative program corresponding to the Web request; assigning a processing function to the collaborative program; and processing with the processing function. Further, as shown in fig. 3, the step of processing with the processing function includes:

s1231, waking up the collaborative program, and executing the processing function to obtain return data;

s1232, performing data slicing in response to the returned data needing slicing;

s1233, in response to acquiring a threshold number of slices, suspending the collaborative process and transmitting the threshold number of slices;

s1234, in response to the data not being sent, steps S1231 through S1233 are performed in a loop.

In the embodiment of the invention, the returned data is obtained by executing the processing function through the collaborative program, when the data volume is large, the data is correspondingly sliced, then transmitted, and when the data is transmitted, the collaborative program is suspended, the requirement on the performance of the chip is reduced, and the data is transmitted circularly until the data is transmitted. The above-mentioned collaborative process and data transmission may be performed in a parallel manner, for example, when data is transmitted, the collaborative process is suspended, and after the data transmission of the slice is completed, the collaborative process is awakened to continue to be executed, the return data is acquired, then the slice is adaptively selected, and then the collaborative process is suspended and the data is transmitted. The adoption of the collaborative program ensures that a plurality of processing requests can be executed, and avoids the situation that other requests are not processed because a single request acquires more data. In order to reduce the requirement on the chip performance, in the embodiment of the invention, 1 slice can be acquired and then transmitted.

In the embodiment of the invention, when the acquired data volume of the returned data is smaller, or no other collaborative program needs to run, the returned data can be directly sent. Specifically, the step of processing by the processing function further includes:

s1235, responding to the returned data without slicing, and directly transmitting the data.

As shown in fig. 4, in the embodiment of the present invention, the problem of insufficient memory of the device is solved by using the collaborative program, so as to ensure the support of access scenarios with larger data volume, the user sends a Web request, establishes a connection for the request, parses the request data, selects a corresponding processing function to process the request, returns the processing result data, and closes the connection. The data processing process adopts a collaborative program, creates the collaborative program for each request and designates a processing function, and the processing flow is as follows: firstly, waking up a collaborative program, and executing a processing function to obtain return data; then, slicing the returned data in sequence, transmitting each time a slice is acquired, suspending the collaborative program before transmitting, waking up after transmitting, and continuing slicing operation until the data is transmitted; and finally closing the connection to complete a request process. The collaborative program ensures that return data of the same request can be continuously and correctly sent.

Further, the step of processing with the processing function further includes: s1236, after data transmission, when the collaborative program is judged to be in a suspended state, the connection is closed. And (5) timely emptying the occupation of resources.

As shown in FIG. 5, the embodiment of the invention can realize remote call of the LUA script in an http mode, trigger a callback function of a receiver after a request arrives, analyze request data by the function to obtain a LUA file name, load a file in a dofile mode to obtain a processing function defined by the script, and transmit the requested parameters to the function to finish data processing work. This approach requires LUA scripts to follow the format definition as: return function (connection, req, args).

The embodiment of the invention provides a Wi-Fi chip based on configurable parameters, and provides a processing method for Web requests. The method can process the scene of a larger data request based on limited memory resources and can also realize remote call of the LUA script.

As shown in fig. 6, the embodiment of the present invention further provides a Web request processing apparatus 200, which is applied to a Wi-Fi chip capable of configuring Wi-Fi parameters, where the apparatus 200 includes:

a connection establishment module 210 configured to establish a connection for a received Web request based on the Web request;

a data processing module 220 configured to remotely invoke the LUA script, and select a processing function corresponding to the Web request to process;

Further, the data processing module 220 is configured to:

Further, the data processing module 220 loads a file in a dofile manner to obtain the LUA function. Further, the data processing module 220 is further configured to create a collaborative program corresponding to the Web request; assigning a processing function to the collaborative program; and processing by using the processing function.

Further, the data processing module 202 is further configured to wake up the collaborative program, execute the processing function to obtain the returned data; responding to the returned data to be sliced, and slicing the data; in response to acquiring a threshold number of slices, transmitting, suspending the collaborative program, and transmitting the threshold number of slices; responding to the fact that the data is not sent completely, and circularly carrying out the steps of waking up and slicing sending until the sending is completed; when the returned data does not need to be sliced, the data is directly transmitted; and after the data is sent, closing the connection when the collaborative program is judged to be in a suspended state.
