This article guides you through setting up WeChat as an identity provider, enabling your Android game to access Player Network authentication services.

Prerequisites

1. Set up the WeChat app on the WeChat Open Platform

1. Create a WeChat app

Register an account on the WeChat Open Platform and create a mobile app in the Admin Center according to the prompts.

2. Get the app information

1. Log in to WeChat Open Platform.

2. At the top navigation bar, click Admin Center.

3. In the Mobile App tab, click View in the Actions column of the corresponding application.

   

4. On the app details page, check the AppID and AppSecret.

   

3. Apply for permissions for your project to obtain AppName

When configuring for a single WeChat channel, AppName is optional. However, when adding multiple WeChat channels, AppName is required and permission has to be obtained from the WeChat management system.

Applying for permissions on WeChat requires internal Tencent access, reach out to the Player Network representative for further assistance.

2. Create an account for Player Network Console.
3. Create a new project for your game, or join an existing one.
4. Download the SDK.
5. Integrate the SDK.
6. Add WeChat as an authentication method for your project on Player Network Console.

Step 1: Configure the SDK for WeChat login

1. Open the project's INTLConfig.ini:

   INTLConfig.ini

   [INTL environment]
   # WARNING: You should change this URL to the production environment when you release your game.
   INTL_URL = https://test.intlgame.com
   GAME_ID = {INTL_GAME_ID}
   SDK_KEY = {INTL_SDK_KEY}
   [INTL Log]
   LOG_LEVEL = 1
   LOG_CONSOLE_OUTPUT_ENABLE = 1
   LOG_FILE_OUTPUT_ENABLE = 1
   LOG_ENCRYPT_ENABLE = 0
   LOG_COMPRESS_ENABLE = 0
   
   [Android LifeCycle]
   LIFECYCLE = WeChat
   [WeChat]
   WECHAT_APP_ID = {INTL_WECHAT_APP_ID}
   • Set the SDK backend environment to INTL_URL = https://test.intlgame.com.
   • Replace {INTL_GAME_ID} and {INTL_SDK_KEY} with the GAME_ID and SDK_KEY assigned by Player Network Console.
   • Set LOG_LEVEL = 1, LOG_CONSOLE_OUTPUT_ENABLE = 1, LOG_FILE_OUTPUT_ENABLE = 1, LOG_ENCRYPT_ENABLE = 0, and LOG_COMPRESS_ENABLE = 0 to output console logs and log files without encrypting or compressing the output.
   • Add WeChat to LIFECYCLE. For more information, see SDK Environment.
   • Replace {INTL_WECHAT_APP_ID} with the AppID assigned by WeChat.

Step 2: Add WeChat login

Permissions are configured when INTLAPI.Login is called. The list of known permissions for WeChat Android is as follows (the official document does not have a clear permission description):

Permissions	Description
snsapi_userinfo	Obtains user information (Player Network SDK's default permission)
snsapi_friend	Gets friend list
snsapi_message	Sends message

1. Add an observer to handle authentication callbacks.

   Unity

   // Add callbacks
   public void AddAuthObserver()
   {
       INTLAPI.AddAuthResultObserver(OnAuthResultEvent);
   }
   
   // Remove callbacks
   public void RemoveAuthObserver()
   {
       INTLAPI.RemoveAuthResultObserver(OnAuthResultEvent);
   }
   
   // Process the INTLAuthResult callback
   public void OnAuthResultEvent(INTLAuthResult ret)
   {
       Debug.Log($"MethodID: {ret.MethodId}");
       
       string methodTag = "";
       if (authRet.MethodId == (int)INTLMethodID.INTL_AUTH_LOGIN)
       {
           methodTag = "Login";
       }
       else if (authRet.MethodId == (int)INTLMethodID.INTL_AUTH_BIND)
       {
           methodTag = "Bind";
       }
       else if (authRet.MethodId == (int)INTLMethodID.INTL_AUTH_AUTOLOGIN)
       {
           methodTag = "AutoLogin";
       }
       else if (authRet.MethodId == (int)INTLMethodID.INTL_AUTH_QUERY_USER_INFO)
       {
           methodTag = "QueryUserInfo";
       }
       else if (authRet.MethodId == (int)INTLMethodID.INTL_AUTH_GET_AUTH_RESULT)
       {
           methodTag = "GetAuthResult";
       }
   }

   Unreal Engine

   C++ Event Handling (above v1.15)

   //configure callback
   FINTLAuthEvent authEvent;
   authEvent.AddUObject(this, &OnAuthResult_Implementation);
   UINTLSDKAPI::SetAuthResultObserver(authEvent);
   // Remove callbacks
   UINTLSDKAPI::GetAuthResultObserver().Clear();

   void OnAuthResult_Implementation(FINTLAuthResult ret)
   { 
       UE_LOG(LogTemp, Warning, TEXT("MethodID: %d"), ret.MethodId);
   }

   Unreal Event Handling

   void OnAuthResult_Implementation(FINTLAuthResult ret)
   { 
       UE_LOG(LogTemp, Warning, TEXT("MethodID: %d"), ret.MethodId);
   }

2. Call the AutoLogin method.

   Unity

   INTLAPI.AutoLogin();

   Unreal Engine

   UINTLSDKAPI::AutoLogin();

3. Call the Login method to ask for user input if auto-login fails.

   Unity

   INTLAPI.Login(INTLChannel.WeChat, "", "");

   Unreal Engine

   UINTLSDKAPI::Login(EINTLLoginChannel::kChannelWeChat, "", "");

4. Sync client authentication state with the game's backend and wait for the final authentication result.

Step 3: Test the login function

Search for the keyword "AuthResult" in the Player Network SDK logs to verify if the correct channel name and OpenID are returned. If they are, it indicates a successful configuration and the login function has been added successfully.
