Download the server-side installation file:

There are two versions: windows version and linux version. The linux version I downloaded can also run on windows.

After opening, there are these files:

You can put this file on the server or in the project. What needs to be run is the last start_for_win.bat file .

Run successfully.

Modify the start_gateway.php file:

Line 24, change the tcp protocol to websocket protocol;

Lines 38 and 40, set the server direction The heartbeat time sent by the client to detect whether the client is connected. If not connected, it will be disconnected.

The following content is commented out by default. You can open or modify it according to your needs.

Run the start_for_win.bat file again:

The protocol will change to the websocket protocol, and you can now perform operations within the project.

You need to download another file: https://github.com/walkor/GatewayClient

Put these files into the thinkphp extend file Fold it (I am using thinkphp5.0 version):

Almost all the methods have been written in the Gateway.php file.

Write a simple front-end page:

Lines 42-52 pass the client_id to the background and bind it to the user in the user table.

Send the message and store it in the database, and the page will be displayed.
