WeChat mini program

// Login in mini program
wx.login({
  success: res => {
    // This is the login code that needs to be sent to Hanzo IAM
    console.log(res.code)
    
    wx.request({
      url: `${IAM_HOSTNAME}/oauth/token`,
      method: "POST",
      data: {
        "tag": "wechat_miniprogram", // Required
        "client_id": "6825f4f0af45554c8952",
        "code": res.code,
        "username": this.data.userInfo.nickName, // Update user profile when you log in.
        "avatar": this.data.userInfo.avatarUrl,
      },
      header:{
        "content-type": "application/x-www-form-urlencoded",
      },
      success: res => {
        console.log(res)
        this.globalData.accessToken = res.data.access_token // Get Hanzo IAM's access token
      }
    })
  }
})

It is important to note that the `tag` parameter is mandatory to inform Hanzo IAM that this is a request from the WeChat Mini Program.

The above code includes the username and avatar URI of the WeChat Mini Program user during login. You can choose to pass these two parameters separately and then pass them to Hanzo IAM after a successful login and obtaining the access token:

```js
wx.getUserProfile({
  desc: 'share your info to Hanzo IAM', 
  success: (res) => {
    this.setData({
      userInfo: res.userInfo,
      hasUserInfo: true
    })
    console.log(app.globalData.accessToken)
    wx.request({
      url: `${IAM_HOSTNAME}/api/update-user`, // Hanzo IAM URL
      method: "POST",
      data: {
        "owner": "test",
        "name": "wechat-oGk3T5tIiMFo3SazCO75f0HEiE7Q",
        "displayName": this.data.userInfo.nickName,
        "avatar": this.data.userInfo.avatarUrl
      },
      header: {
        "Authorization": "Bearer " + app.globalData.accessToken, // Bearer token
        "content-type": "application/json"
      },
      success: (res) => {
        console.log(res)
      }
    })
  }
})

Additionally, you can use the access token as a bearer token for any Hanzo IAM operation you require.

:::info Tips

Currently, Hanzo IAM is unable to bind existing accounts to WeChat Mini Program users. After Hanzo IAM retrieves the OpenID from WeChat, it will either create a new user if the ID does not exist, or use the existing user if it does.
