This sample source code contains the sample source code of GoClass Client and GoClass Server. This article describes how to run the sample source code. It is recommended that the client and server be used together. The guidelines are divided into two parts:

1. Guidelines for running the sample source code of the GoClass client.
2. Guidelines for running the example source code of GoClass server (Golang).

1 GoClass Client Sample Code Operation Guidelines

1.1 Prepare the Environment

1. Node has been installed.

2. A browser supported by ZEGO SDK has been installed, as shown in the following table:

1.2 Prerequisites

Please go to ZEGO Management Console to register an account and apply for the AppID and Server required to initialize the SDK. For the application process, please refer to Project Management.

1.3 Notes

• The downloaded sample source code lacks the APP_ID required for SDK initialization, so you need to modify the src/go_class_web/src/utils/config_data.js file. Please use the AppID obtained in the "Prerequisites" of this article to fill in correctly.

• In the sample source code, please refer to Room Login Security to obtain the token required to log in to the room, and fill in the interface for obtaining the token correctly in src/go_class_web/src/utils/config_data.js YOUR_SDK_TOKEN_URL.

• You need to configure the host address of the locally deployed GoClass server in the corresponding field of src/go_class_web/src/utils/config_data.js. After the background service is deployed successfully, the access address is assumed to be http://127.0.0.1:7779, and the background service address must be filled in as http://127.0.0.1:7779 +'/edu_room'.

• Obtaining the camera microphone must be run in the HTTPS environment. Before integrating the SDK, please ensure that the final project can run in the HTTPS environment.

• Both the project deployment environment and the background environment need to be consistent.

1.4 Run Sample Code

1. Switch to the directory where the project is located in Terminal and execute yarn install or npm install command to install dependencies.

2. Execute the yarn serve or npm run serve command in the Terminal to run the sample source code. After running successfully, access the local server (https://***) in the browser. The example is as follows:

​  Project is running at https://localhost:8080/

2 GoClass Server (Golang) Sample Code Operation Guidelines

2.1 Environmental Preparation

• Golang 1.11 or above has been installed (recommended 1.13 or above).

• Redis 2.6 or above has been installed.

2.2 Prerequisites

Please go to ZEGO Management Console to register an account and apply for AppID and ServerSecret. Refer to Project Management.

2.3 Run Sample Code

1. Download the GoClass source code.

git clone https://github.com/zegoim/go-class.git

2. Enter the configuration directory src/go_class_server/go_class_room/conf/.

cd src/go_class_server/go_class_room/conf/

3. Modify the relevant configuration items in the app.conf file.

RedisAddr = "192.168.100.62:6379" # redis host
RedisPassword = "" # redis password
RedisIndex = 8 # redis database

[SmallClass] # Small class class appid related configuration If you don’t need small class scene, you don’t need to care about related configuration
AppId = 123456789
AppSecret = "eb2280544902dc1b7ab1fde3985bd083" # ServerSecret obtained from ZEGO console
...
MaxPeopleNum = 10 # The maximum number of people online at the same time in the classroom
MaxJoinLiveNum = 4 # The maximum number of simultaneous microphones in the small class classroom

[LargeClass] # Large class class appid related configuration If you don’t need large class scenario, you don’t need to care about related configuration
AppId = 987654321
AppSecret = "13nce767a02dc1b7bd083ab1fde3985" # ServerSecret obtained from ZEGO console
...
MaxPeopleNum = 50 # Maximum number of simultaneous online people in large classes
MaxJoinLiveNum = 1 # Maximum number of simultaneous microphones in the classroom

4. Enter the go_class_room directory and start the service.

cd ../go_class_room
go run main.go
