S110: Receive a Web request and establish a connection for the Web request; the Wi-Fi chip in the embodiment of the present invention, such as the ESP8266 chip, is divided into two operating modes, namely the configuration mode and the working mode. The two modes are switched by a switch . The device must enter the configuration mode when it is used for the first time. The operation method is to set the switch to the 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 HTTP requests. The client connects to the WI-FI network of the device and accesses the Web service through the browser. The web server listens to the http request and processes it, and returns the processed result to the client. The configuration mode supports the configuration of Wi-Fi information and cloud server information. After the configuration is complete, set the switch to off, and restart the device to enter the working mode. In the working mode, the device first connects to Wi-Fi, then performs time calibration on the device, and then connects to the cloud server. After completing the above tasks, the device starts to transmit data. The workflow is shown in Figure 2.

S120: Remotely call the LUA script, select the processing function corresponding to the Web request for processing; parse the Web request to obtain the corresponding processing function for data processing, such as data query, data calculation, data packaging, etc., to form the processing result .

S130: Return the processing result data; after the processing result is obtained, the data is packaged and sent according to the adopted data protocol, for example, the HTTP protocol is used for sending.

In the embodiment of the present invention, a Wi-Fi chip is used to build a server function. Due to the limited new capabilities of the Wi-Fi chip, there is no mature Web service framework. In order to meet the requirements of providing Web services, a set of Web service frameworks are implemented based on the LUA basic library. LUA is a lightweight and compact scripting language. The Wi-Fi chip can carry such scripting language functions to run, and realize server functions by remotely calling LUA scripts.

The key technologies of the Web server include creating a TCP server (Transmission Control Protocol Server), capturing HTTP (Hypertext Transfer Protocol) requests and establishing a connection, parsing and processing the requested data, returning the result to the client in the form of http, and closing the connection. This embodiment mainly implements the analysis and processing of http request data. According to the selection, the features are as follows:

1) Support a variety of request methods, including get (get), post (post), put (place), etc., and analyze according to different web request methods.

2) Support http access authentication.

3) Realize remote calling of LUA scripts in http mode.

4) Support multiple request codes.

5) It can correctly handle scenarios where a single request returns a large amount of data.

In the embodiment of the present invention, the steps of remotely calling the LUA script and selecting the processing function corresponding to the Web request for processing include:

Trigger the receive event, parse the requested data, obtain the LUA file name, load the file to obtain the LUA function, execute the LUA function, trigger the sent event, and send the result obtained by executing the LUA function.

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

Use dofile to load files to obtain the LUA function.

In order to realize the scenario of processing a large amount of data on a Wi-Fi chip with limited performance, the method of processing Web requests in the implementation of the present invention adopts a cooperative program to process, which can reduce the requirements for device performance without causing data transmission. mistake. Specifically, the step of selecting a processing function corresponding to the Web request for processing includes: creating a cooperative program corresponding to the Web request; specifying a processing function for the cooperative program; and processing using the processing function. Further, as shown in Figure 3, the steps of using the processing function for processing include:

S1231: Wake up the cooperative program and execute the processing function to get the return data.

S1232: Perform data slicing in response to the need to slice the returned data.

S1233: In response to obtaining the threshold number of slices, suspend the cooperative program, and send the threshold number of slices.

S1234: Responding to the fact that the data has not been sent, step S1231 to step S1233 are executed in a loop.

In the embodiment of the present invention, the return data is obtained by executing the processing function through the cooperative program. When the amount of data is large, the data is sliced and then sent. When sending, the cooperative program is suspended to reduce the performance requirements of the chip, and the data is sent in a loop until the data is sent. Sent. The aforementioned cooperative program and data sending can be carried out in a similar parallel manner. For example, the cooperative program is suspended when sending data, and after the sliced data is sent, the cooperative program is awakened to continue execution, obtain the returned data, and then adaptively select the slice and suspend The collaborative program then sends the data. The use of a cooperative program ensures that multiple processing requests can be executed, avoiding the situation that other requests are not processed due to a single request for obtaining more data. In order to reduce the requirements on the performance of the wafer, in the embodiment of the present invention, one slice may be obtained and sent immediately.

In the embodiment of the present invention, when the amount of returned data obtained is small, or when there is no other cooperative program to run, it can be sent directly. Specifically, the processing steps of the processing function further include:

S1235: Responding to the returned data without slicing, the data is sent directly.

As shown in Figure 4, in the embodiment of the present invention, a cooperative program is used to solve the problem of insufficient device memory and to ensure support for larger data access scenarios. The user sends a Web request, establishes a connection for the request, analyzes the requested data, and selects The corresponding processing function processes the request, returns the processing result data and closes the connection. The data processing process adopts a cooperative program. A cooperative program is created for each request and a processing function is specified. The processing flow is: first wake up the cooperative program, execute the processing function to obtain the returned data; then, slice the returned data in sequence, and each slice is obtained Send, suspend the cooperative program before sending, wake up after sending and continue the slicing operation until the data is sent; finally close the connection to complete a request process. The cooperative program ensures that the returned data of the same request can be sent continuously and correctly.

Further, the step of processing using the processing function further includes: S1236: After the data is sent, when it is determined that the cooperative program is in a suspended state, the connection is closed. Clear the occupation of resources in time.

As shown in Figure 5, the embodiment of the present invention can remotely call the LUA script via http. After the request arrives, the receive callback function is triggered. This function parses the requested data, obtains the LUA file name, and then uses dofile Load the file in a way to get the processing function defined by the script, and pass the requested parameters to the function to complete the data processing work. This method requires the LUA script to follow the format definition: return function (connection, req, args).

The embodiment of the present invention provides a processing method for Web requests based on a Wi-Fi chip with configurable parameters. It can process larger data requests based on limited memory resources, and it can also realize remote calling of LUA scripts.
