每当我尝试使用react-native-firebase sdk登录电话号码时,我都会通过短信接收OTP代码,并且当我提交收到的代码时,会出现错误消息:“短信代码已过期。请重新发送验证码再试一次。”这里要注意的是,即使有错误,各个电话号码的条目也会写入firebase的“用户”部分。
我正在使用以下内容:
NodeJS: v8.11.1,
NPM: v5.6.0,
react-native: "^0.59.9",
react-native-firebase: "^5.5.3"

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:应该验证代码,并且应该在firebase的“用户”部分中输入一个条目,然后导航到SetupCoverVideo。
实际结果:遇到错误消息:“短信代码已过期。请重新发送验证码,然后重试。”这里要注意的是,即使有错误,各个电话号码的条目也会写入firebase的“用户”部分。
我想知道解决方案。任何人都可以帮助我。

显然,某些最新版本的Android足够聪明,可以接收SMS验证码并使用它来验证用户身份。此身份验证发生在后台,而用户仍通过SMS接收验证码。。当用户尝试输入验证码时,他/她会收到一条消息,提示验证码已过期,因为Android已在后台使用它并已登录用户!要再次检查,请检查Firebase控制台。您应该发现此新用户已添加到用户列表中。
为避免收到验证码过期消息,我们需要为身份验证更改设置侦听器。 Android在后台登录用户后,此侦听器应立即将用户从登录屏幕中移出,该用户应在该登录屏幕中输入验证码。下面演示了如何实现。我将以下代码添加到登录屏幕。
与功能组件一起使用的示例代码:
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" });
}
});
}, []);
与类组件一起使用的示例代码:
// 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,
});
}
});
};
