如何使用React Native进行Firebase Twitter身份验证？

我在参考https://www.firebase.com/docs/web/guide/login/twitter.html

时尝试了以下两个代码

var Firebase = require("firebase");

var App = React.createClass({

  render: function() {
    return (
      <View>
        <Text onPress={this._handlePress}>
          Twitter login
        </Text>
      </View>
    );
  },

  _handlePress: function () {
    var myApp = new Firebase("https://<myapp>.firebaseio.com");

    myApp.authWithOAuthRedirect("twitter", function(error) {
      if (error) {
        console.log("Login Failed!", error);
      } else {
        // We'll never get here, as the page will redirect on success.
      }
    });

  }

});

和

var Firebase = require("firebase");

var App = React.createClass({

  render: function() {
    return (
      <View>
        <Text onPress={this._handlePress}>
          Twitter login
        </Text>
      </View>
    );
  },

  _handlePress: function () {
    var myApp = new Firebase("https://<myapp>.firebaseio.com");

    myApp.authWithOAuthPopup("twitter", function(error, authData) {
      if (error) {
        console.log("Login Failed!", error);
      } else {
        console.log("Authenticated successfully with payload:", authData);
      }
    });

  }

});

当我使用authWithOAuthRedirect时，发生了错误，如

undefined is not an object (evaluating 'window.location.href')

当我使用authWithOAuthPopup时，什么也没发生。

我该如何解决这个问题？或者是不可能的？

Answer 1

这是针对网络的Firebase Twitter集成。尽管它的祖先和它使用JavaScript，React Native绝不是网络;你没有DOM，你没有浏览器，所以你没有能力重定向当前窗口，这似乎是这段代码试图做的。

因此，要回答您的问题，将无法使用此库。您可能会发现必须在Obj-C中编写扩展来执行您想要执行的操作而不使用浏览器样式的流程。

我一起解决了一个问题...我确信有一种更清洁的方法可以用来完成工作，但你可以建立在我已经完成的工作上

/**
* login in the user with the credentials, gets the whole process 
* started, [NOTE] probably can just construct the url myself?
*/
_doGitHubLogin() {
    this.props.fbRef.authWithOAuthRedirect("github", function (error) {
        if (error) {
            console.log("Authentication Failed!", error);
        } else {
            console.log("Authenticated successfully with payload:", authData);
        }
    });
}

componentDidMount() {

    // set this interval to check for me trying to redirect the window...
    var that = this
    that.inter = setInterval(function () {
        if (window.location && window.location.split) {

            // set the redirect on the url..
            var newLocation = window.location.split("redirectTo=null")[0]
            newLocation = newLocation + "redirectTo=https://auth.firebase.com/v2/clearlyinnovative-firebasestarterapp/auth/github/callback"

            // open the browser...
            that.setState({ url: newLocation })

            // clear the interval to stop waiting for the location to be set..
            clearInterval(that.inter)
        }
    }, 3000);


    this.props.fbRef.onAuth((_auth) => {
        console.log(_auth)
        this.setState({ auth: _auth })
    });
}
