2. Introduction to mobile rear end: E chat SDK provides a basic back-end community version source code. By compiling / modifying the back-end source code, you can achieve deeper business customization, such as file upload / download, online / offline monitoring, API permission function, cluster function, etc. The backend project uses springboot+mybatis for development and maven for project management. The following describes how to compile back-end projects from source.

3. Operation steps: 3.1 download the source code of broker Release v1.01

git clone https://gitee.com/dzqmeiji/echatim-server-broker-community.git
cd echatim-server-broker-community/
git checkout -b v1.01 v1.01
mvn clean package -DskipTests=true  # Compile backend Middleware

3.2 download the source code of server Release v1.01

git clone https://gitee.com/dzqmeiji/echatim-server-community.git
cd echatim-server-community/
git checkout -b v1.01 v1.01
mvn clean package -DskipTests=true  # Compile backend project

3.3 download the source code of server Release v1.01

git clone https://gitee.com/dzqmeiji/echatim-server-community.git
cd echatim-server-community/
git checkout -b v1.01 v1.01
mvn clean package -DskipTests=true  # Compile backend project

3.4 import database structure and initial data Install MySQL 5.7 data service, create echatim database in mysql, import sqls/echatim-2020-04-30.sql file to echatim database. Create mysql root user with blank password

3.5 start backend project

cd server-community-deploy/target/
java -jar server-community-deploy-1.0.jar

After successful startup, you can see:

swagger test started. http://localhost:8082/swagger-ui.html
socket.io started. http://localhost:9092

API debugging: http://localhost:8082/swagger-ui.html socketIO address: http://localhost:9092

3.6 edit Web client configuration Source address

We use the E-chat local server as the chat background, and the configuration uses the local server configuration (there is no file service function in the community version)

//      src/main.js  Document content
719     sdkConfig.host = 'localhost';  //Use local server
720     sdkConfig.httpPort = 8082;  //Use local default configuration
721     sdkConfig.socketPort = 9092;  //Use local default configuration
722     sdkConfig.key = 'TSDKTEST00001'; # View database sdk_app table
723     sdkConfig.secret = '';  // This is a reserved configuration and does not need to be changed

Use yarn start to use the local back-end project to realize the chat function

3.7 edit mobile client configuration Source address

We use the E-chat local server as the chat background, and the configuration uses the local server configuration (there is no file service function in the community version)

//      src/dev.ts  Document content
export const DevConfig = {
    HOST:'localhost',
    FILE_SERVER_URL:'http://localhost:8082',
};

//      src/AppInitializer.ts  Document content
  sdkConfig.httpPort = 8082; //Use local default configuration
  sdkConfig.socketPort = 9092; //Use local default configuration
  sdkConfig.key = 'TSDKTEST00001;
  sdkConfig.secret = ''; // This is a reserved configuration and does not need to be changed

//  . env file content
  SKIP_PREFLIGHT_CHECK=true
  # config web
  HOST=192.168.0.100 # Change to local IP address
  PORT=18088

Using yarn web, you can use the local back-end project to realize the chat function

4. Summary: The Web back-end project provides a back-end implementation with only basic functions. More functions need to be customized freely, which also brings greater expansibility and flexibility to the project.
