如何从 reactnativefbsdk 获取用户信息(邮箱、姓名等)

发布于05月27日

当一个用户通过Facebook认证时，我试图访问该用户的邮箱和姓名以设置和帐户.我已经准备好了react native fbsdk的文档，但我哪儿都没看到.

推荐答案

你可以这样做(这是我在我的应用程序中所做的简化版本):

<LoginButton
  publishPermissions={['publish_actions']}
  readPermissions={['public_profile']}
  onLoginFinished={
    (error, result) => {
      if (error) {
        console.log('login has error: ', result.error)
      } else if (result.isCancelled) {
        console.log('login is cancelled.')
      } else {
        AccessToken.getCurrentAccessToken().then((data) => {
          const { accessToken } = data
          initUser(accessToken)
        })
      }
    }
  }
  onLogoutFinished={logout} />

//功能initUser

initUser(token) {
  fetch('https://graph.facebook.com/v2.5/me?fields=email,name,friends&access_token=' + token)
  .then((response) => response.json())
  .then((json) => {
    // Some user object has been set up somewhere, build that user here
    user.name = json.name
    user.id = json.id
    user.user_friends = json.friends
    user.email = json.email
    user.username = json.name
    user.loading = false
    user.loggedIn = true
    user.avatar = setAvatar(json.id)      
  })
  .catch(() => {
    reject('ERROR GETTING DATA FROM FACEBOOK')
  })
}
