每当我使用react-native-firebase sdk尝试使用手机号码登录时,我都会通过短信收到OTP代码,当我提交收到的代码时,会出现一个错误:“短信代码已过期。请重新发送验证码重试。”这里需要注意的是,即使有错误,也会在firebase的用户部分中写入相应电话号码的条目。
我正在使用以下代码:
NodeJS: v8.11.1,
NPM: v5.6.0,
react-native: "^0.59.9",
react-native-firebase: "^5.5.3"我已经尝试过的一些链接是:

auth在MobileRegistration.js中:
navigateToOtpScreen() {
console.log("Phone number: ", "+91" + this.state.phoneNumber)
firebase.auth().signInWithPhoneNumber("+91" +
this.state.phoneNumber)
.then(confirmResult => {
this.setState({ confirmResult, message: 'Code has been sent!'})
this.props.navigation.navigate('EnterOtp', { 'confirmResult':
confirmResult})
})
.catch(error => {
alert(error.message);
this.setState({ message: `Sign In With Phone Number Error:
${error.message}` })
});};
在EnterOtp.js中:
componentDidMount() {
this.unsubscribe = firebase.auth().onAuthStateChanged((user) => {
alert(JSON.stringify(user));
if (user) {
this.setState({
user: user.toJSON()
});
} else {
// User has been signed out, reset the state
this.setState({
user: null,
message: '',
otp: '',
otp1: '',
otp2: '',
otp3: '',
otp4: '',
otp5: '',
otp6: ''
});
}
});}
componentWillUnmount() {
if (this.unsubscribe) this.unsubscribe();}
verifyOTP = async () => {
const {
confirmResult,
} = this.props.navigation.state.params;
let otp = this.state.otp + "" + this.state.otp1 + "" + this.state.otp2 + "" + this.state.otp3 + "" + this.state.otp4 + "" + this.state.otp5 + "" + this.state.otp6
if (confirmResult && otp.length) {
alert(otp);
confirmResult.confirm(otp).then((user) => {
AsyncStorage.setItem('accessToken', confirmResult._verificationId);
this.props.navigation.navigate('SetupCoverVideo');
this.setState({
message: 'Code Confirmed!'
});
})
.catch(error => {
alert(error.message) && this.setState({
message: `Code Confirm Error: ${error.message}`
})
});
}}
预期结果:代码应该经过验证,在firebase的Users部分中应该有一个条目,并导航到SetupCoverVideo。
实际结果:遇到错误提示:短信已过期,请重新发送验证码重试。这里需要注意的是,即使有错误,也会在firebase的用户部分中写入相应电话号码的条目。
我想知道解决方案。任何人请帮帮我。

显然,最近的一些Android版本足够智能,可以接收短信验证码,并使用它来验证用户身份。当用户尝试输入验证码时,他/她会收到一条消息,告诉他/她验证码已经过期了,因为安卓已经在后台使用过验证码并且已经登录了用户!要再检查一遍,请检查控制台。您应该会发现此新用户已添加到用户列表中。
为了避免收到验证码过期消息,我们需要为“changes”设置一个监听器。Android在后台登录用户后,此监听器应立即引导用户离开登录屏幕,他/她应该在登录屏幕中输入验证码。下面演示了如何实现这一点。我会将以下代码添加到登录屏幕。
使用函数组件的示例代码:
useEffect( () => {
firebase.auth().onAuthStateChanged( (user) => {
if (user) {
// Obviously, you can add more statements here,
// e.g. call an action creator if you use Redux.
// navigate the user away from the login screens:
props.navigation.navigate("PermissionsScreen");
}
else
{
// reset state if you need to
dispatch({ type: "reset_user" });
}
});
}, []); 使用类组件的示例代码:
// I did NOT test this version, because I use functional components.
componentDidMount() {
firebase.auth().onAuthStateChanged( (user) => {
if (user) {
// Obviously, you can add more statements here,
// e.g. call an action creator if you use Redux.
// navigate the user away from the login screens:
props.navigation.navigate("PermissionsScreen");
}
else
{
// reset state if you need to
this.setState({
user: null,
messageText: '',
codeInput: '',
phoneNo: '',
confirmResult: null,
});
}
});

您需要使用以下命令检查后台身份验证:
conponentDidMount() {
firebase.auth().onAuthStateChanged((user) => {
if (user) {
// alert(JSON.stringify(user))
// Obviously, you can add more statements here,
// e.g. call an action creator if you use Redux.
// navigate the user away from the login screens:
}
});
}然后你需要注销你的用户,一旦你完成了它(我遇到了这个问题,旧用户会话已经存在,而新用户正在进行身份验证)
因此,在注销时使用:
if (firebase.auth().currentUser)
firebase.auth().currentUser.delete();你已经准备好了!
