Login Functions

User Login minigameApi.login(options)

Callback Style:

// User login with callbacks
minigameApi.login({
  success: function(result) {
    console.log('Login successful:', result);
  },
  fail: function(error) {
    console.log('Login failed:', error);
  }
});

Promise Style:

// User login with Promise
minigameApi.login()
  .then(result => {
    console.log('Login successful, jwtToken:', result.data.jwtToken);
  })
  .catch(error => {
    console.log('Login failed:', error);
  });

// Or using async/await
async function handleLogin() {
  try {
    const result = await minigameApi.login();
    console.log('Login successful:', result);
  } catch (error) {
    console.log('Login failed:', error);
  }
}

Parameter Description

Parameter	Type	Required	Description
success	Function	No	Login success callback function
fail	Function	No	Login failure callback function

Note: When using Promise style, you can omit the success and fail callbacks and use .then() and .catch() instead.

Success Callback Parameters:

{
  code: 0,
  message: 'success',
  data: {
    jwtToken: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...',
    expiresIn: 3600,
    refreshToken: 'rt_xxxxxxxxxxxxxxxx'
  }
}

Failure Callback Parameters:

{
  code: -1,
  message: 'Error description',
  error: 'ERROR_CODE'
}

Best Practices: Promise-based Login Flow

// Modern async/await login flow
class GameManager {
  constructor() {
    this.minigameApi = midas.minigame(config);
    this.setupEventListeners();
  }

  async initializeGame() {
    try {
      // Wait for SDK to load
      await this.waitForSDKLoad();
      
      // Attempt login
      const loginResult = await this.minigameApi.login();
      console.log('User logged in, jwtToken:', loginResult.data.jwtToken);
      
      // Show game menu after successful login
      await this.minigameApi.showMenu({ gradually: true });
      
    } catch (error) {
      console.error('Game initialization failed:', error);
      this.handleInitError(error);
    }
  }

  waitForSDKLoad() {
    return new Promise((resolve) => {
      this.minigameApi.on('sdk:loaded', resolve);
    });
  }

  handleInitError(error) {
    // Handle initialization errors
    if (error.code === 'MODULE_NOT_LOADED') {
      console.error('SDK modules not loaded properly');
    }
  }
}
