SDK Instruction

Log Initialization

Log Initialization function func InitLogger(log LogInterface, option interface{}). demo: common.InitLogger(common.NewCommonLogger(), common.DefaultOption())

Developers can use the custom log library by implementing the LogInterface interface

SDK Initialization

You must init app config before using SDK. You can follow these steps to do it.

1. Get necessary information, such as AppID, AppSecret, VerifyToken and EncryptKey. But you'd better not use clear text in code. Getting them from database or environment variable is a better way.
2. Init app config.
3. Get appTickey if your app is Independent Software Vendor App, otherwise you can ignore this.
4. Register events what you want.

Example code

1. get config from redis.
   demo code
2. get config from environment variable.

conf := &appconfig.AppConfig{
    AppID: os.Getenv("AppID"),              //get it from lark-voucher and basic information。
    AppType: protocol.InternalApp,          //AppType only has two types: Independent Software Vendor App（ISVApp） or Internal App.
    AppSecret:   os.Getenv("AppSecret"),    //get it from lark-voucher and basic information.
    VerifyToken: os.Getenv("VerifyToken"),  //get it from lark-event subscriptions.
    EncryptKey:  os.Getenv("EncryptKey"),   //get it from lark-event subscriptions.
}

DB-client Initialization

DBClient SDK DB Client interface.
It is used for: read/write app ticket ; read/write user session data for authentication operations; read sensitive information such as app secret.

DefaultRedisClient Default Redis Client. Need to be initialized before use.
demo:

redisClient := &common.DefaultRedisClient{}
err := redisClient.InitDB(map[string]string{"addr": "127.0.0.1:6379"})
if err != nil {
    return fmt.Errorf("init redis-client error[%v]", err)
}

Developers can use the custom db client library by implementing the DBClient interface

./botframework-go -f ./generatecode/demo.yml

Generate Code Rule

• If the code is first generated, all code files are generated by the configuration file.
• If you modify the configuration file later, and regenerate the code on the original path, only the ./handler/regist.go file will be forced updated, other files are not updated to avoid overwriting user-defined code.
• Because the ./handler/regist.go file will be forced update, you should not write your business code in the file.

demo

• Manage AppAccessToken
• Manage TenantAccessToken
• Webhook_Event
• Webhook_Card
• Send Message
• Build Card
• Authentication
