“ auth / network-request-failed”，尝试在React Native应用中使用Firebase登录时

Question

[当我尝试在我的本机应用程序中使用Firebase（v6）登录时遇到问题。

这是问题：

这是我的代码：

Firebase.js

这是允许我们使用firebaseConfig初始化应用的功能

    import {firebase} from '@react-native-firebase/auth';

const firebaseConfig = {
  apiKey: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
  authDomain: 'xxxxxxxx.firebaseapp.com',
  databaseURL: 'https://xxxxxxxx.firebaseio.com',
  projectId: 'xxxxxxxxx',
  storageBucket: 'xxxxxxxxx.appspot.com',
  messagingSenderId: 'xxxxxxxxxx',
  appId: 'xxxxxxxxxxx'
};

firebase.initializeApp(firebaseConfig);

export default firebase;

ModalLogin.js

这是检查登录的主要代码。

import React from 'react';
import styled from 'styled-components';
import {
  TouchableOpacity,
  Alert,
  Dimensions,
  Animated,
  TouchableWithoutFeedback,
  Keyboard,
} from 'react-native';
import {BlurView, VibrancyView} from '@react-native-community/blur';
import {connect} from 'react-redux';
import Success from './Success';
import Loading from './Loading';
import firebase from './Firebase';
import auth from '@react-native-firebase/auth';

const screenHeight = Dimensions.get('window').height;

function mapStateToProps(state) {
  return {action: state.action};
}

function mapDispatchToProps(dispatch) {
  return {
    closeLogin: () =>
      dispatch({
        type: 'CLOSE_LOGIN',
      }),
  };
}

class ModalLogin extends React.Component {
  state = {
    email: '',
    password: '',
    iconEmail: require('../Images/icon-email.png'),
    iconPassword: require('../Images/icon-password.png'),
    isSuccessful: false,
    isLoading: false,
    scale: new Animated.Value(1),
    translateY: new Animated.Value(0),
    top: new Animated.Value(screenHeight),
  };
  componentDidUpdate() {
    if (this.props.action == 'openLogin') {
      Animated.timing(this.state.top, {
        toValue: 0,
        duration: 0,
      }).start();
      Animated.spring(this.state.scale, {toValue: 1}).start();
      Animated.timing(this.state.translateY, {
        toValue: 0,
        duration: 0,
      }).start();
    }

    if (this.props.action == 'closeLogin') {
      setTimeout(() => {
        Animated.timing(this.state.top, {
          toValue: screenHeight,
          duration: 0,
        }).start();
        Animated.spring(this.state.scale, {toValue: 1.3}).start();
      }, 500);

      Animated.timing(this.state.translateY, {
        toValue: 1000,
        duration: 500,
      }).start();
    }
  }

  handleLogin = () => {
    this.setState({isLoading: true});

    const email = this.state.email;
    const password = this.state.password;

    firebase
      .auth()
      .signInWithEmailAndPassword(email, password)
      .catch(function(error) {
        Alert.alert('Error', error.message);
      })
      .then(response => {
        console.log(response);
        this.setState({isLoading: false});
        if (response) {
          // Successful
          this.setState({isSuccessful: false});
          //storage
          //this.storeName(response.user.email);
          this.fetchUser();
          this.props.updateName(response.user.email);
          //
          Alert.alert('Congrats', "You've logged in successfully!");
          setTimeout(() => {
            Keyboard.dismiss();
            this.props.closeLogin();
            this.setState({isSuccessful: false});
          }, 1000);

          console.log(response.user);
        }
      });
  };

  // change the image on tape
  focusEmail = () => {
    this.setState({

通常，它应该可以工作。我不知道问题出在哪里。您能帮我解决一个问题吗？谢谢

您需要停止远程JS调试，然后再次运行：react-native run-ios从> 0.6开始，调试中出现问题。您可以尝试：react-native log-ios进行调试或使用一堆警报。
