React-native fbsdk获取名称和电子邮件

Question

我正在使用react-native-fbsdk。我想获取用户名和电子邮件，以便在用户注册到应用时向用户显示，以便为应用创建配置文件，但不会显示任何数据。如何获取这些数据以及如何在不同的屏幕中显示它们。

这是我的代码

import FBSDK from 'react-native-fbsdk'
import { LoginButton,AccessToken,GraphRequest,GraphRequestManager} from 'react-native-fbsdk';


const {
  LoginManager,
} = FBSDK;

<LoginButton
        readPermissions={['public_profile']}
          onLoginFinished={
            (error, result) => {
              if (error) {
                alert("login has error: " + result.error);
              } else if (result.isCancelled) {
                alert("login is cancelled.");
              } else {
                AccessToken.getCurrentAccessToken().then(
                  (data) => {
                    const infoRequest = new GraphRequest(
                      '/me?fields=name,picture',
                      null,
                      this._responseInfoCallback
                    );
                    // Start the graph request.
                    new GraphRequestManager().addRequest(infoRequest).start();
                  }
                )
              }
            }
          }
          onLogoutFinished={() => alert("logout.")}/>
      </View>
    );
  }
  _responseInfoCallback = (error, result) => {
    if (error) {
      alert('Error fetching data: ' + error.toString());
    } else {
      alert('Result Name: ' + result.name);
    }
  }

}

谢谢朋友

我使用firebase时检索facebook登录。

1. 导入此文件： 从“react-native-firebase”导入firebase; 从“react-native-fbsdk”导入{AccessToken，LoginManager};
2. 单击按钮时，Firebase登录代码有效： export const fbLogin =（）=> {

   LoginManager.logInWithReadPermissions(["public_profile", "email"])
     .then(result => {
       if (result.isCancelled) {
         console.log("Login was cancelled");
       }
       return AccessToken.getCurrentAccessToken();
     })
     .then(data => {
       const credential = firebase.auth.FacebookAuthProvider.credential(
         data.accessToken
       );
      firebase
       .auth()
       .signInWithCredential(credential)
       .then(result => {
        Toast.show({
         text: "Sucessfully",
         position: "top"
       });
      console.log("Successfully Login", result);
    })
     .catch(error => {
      console.log("Failed", error);
        });
     })
     .catch(err => {
       console.log("fail", err);
     }); 

   };

我检索我的facebook登录数据

 console.log("Successfully Login", result);

结果包含用户名，电子邮件，图片和..ect凭据

如果你不想使用firebase，

const infoRequest = new GraphRequest(
        '/me?fields=name,email,picture.type(large)',
        null,
        this._responseInfoCallback
      );
      new GraphRequestManager().addRequest(infoRequest).start();


_responseInfoCallback = (error, result) => {
    if (error) {
      alert('Error fetching data: ' + error.toString());
    } else {
      this.setState({ userName: result.name, userEmail: result.email ,userPic:result.picture.data.url});
              AsyncStorage.setItem("UserName",this.state.userName);
                    AsyncStorage.setItem("Email", this.state.userEmail);
                    AsyncStorage.setItem("UserPic", this.state.userPic);

      //  SharedPreferences.setItem("UserName", this.state.userName);
      //       SharedPreferences.setItem("Email", this.state.userEmail);
      //       SharedPreferences.setItem("UserPic", this.state.userPic);
      console.log("Picture"+ this.state.userPic + "Name" + this.state.userName + "Email" + this.state.userEmail);
    }
  }
