Socket communication tool for Android simulation server to send messages
1. Background
Background introduction:
Some scenarios need to rely on the server to send messages to the client, such as PowerMsg, the server sends the message type, and the client parses the type to take corresponding actions. For example, live answering questions needs to rely on the server to send messages, and the client gets the messages to display the questions according to the rules, etc.
2. Explanation of Pain Points
Relying on the sending of messages from the server, the client is very passive and cannot actively construct corresponding messages. So there is an urgent need for a tool that can simulate server-side message delivery, and the socket tool comes from this.
3. Tool principle
The computer simulates the Socket server, the Android application simulates the Socket client, and sends messages to the client through the socket tool.

5. Socket server tool
1. Install the software
Install software: SSokit
SSokit address
2. Step reference
1. Open the software, automatically identify the current computer address, manually enter the port number, such as: 7653
2. Shake the phone, enter the Ip, port number, click the button to set the simulated PowerMsg; turn on the switch.
3. Display connected
4. Send text in the input box on the right, format reference:
{
"type": 1,
"data": {
"uniqueKey":"1629428186122:-875441502",
"type":1304,
"body":{
"questionId":12312312312312
}
}
