Question

我正在寻找本机响应的方法，以使用户使用他的电话号码进行注册，然后添加他的电子邮件和密码。但是，当用户登录时，他只能使用电子邮件和密码登录。

电话号码仅出于安全原因。

我在用户验证其号码后执行signInWithPhoneNumber（），我调用了createUserWithEmailAndPassword（），但这是在控制台Auth中进行的两次同时进行的独立身份验证 “电子邮件”和“电话号码”

代码

// I just pass the result into separate screen then use it to confirm all stuff is work :D

...
auth()
        .signInWithPhoneNumber(phoneWithAreaCode, true)
        .then(confirmResult => {
          console.log('2', phoneWithAreaCode);
          console.log('confirmResult', confirmResult);
          this.setState({
            confirmResult,
            loading: false,
          });
        })
...

confirmCode = codeInput => {
    const {confirmResult, email, password} = this.state;
    console.log('codeInput Is:', codeInput.length);
    if (confirmResult && codeInput.length) {
      confirmResult
        .confirm(codeInput)
        .then(async () => {
          clearInterval(this.interval);
          const {params} = this.props.navigation.state;
          await auth()
            .createUserWithEmailAndPassword(email, password)
            .then(({user}) => {
              console.log('hey u');
              let uid = user.uid;
              params.createUser(uid);
            })
            .catch(error => {
              // Handle Errors here.
              var errorCode = error.code;
              switch (errorCode) {
                case 'auth/email-already-in-use':

如果要为同一用户使用多个身份验证提供程序，则需要链接它们以防止创建单独的用户。要链接它们，您可以使用linkWithCredential()例如：

var credential = firebase.auth.EmailAuthProvider.credential(email, password);

此处将电子邮件和密码传递给EmailAuthProvider.credential方法，然后可以将AuthCredential对象传递给已登录用户的linkWithCredential方法：

firebase.auth().currentUser.linkWithCredential(credential).then(function(usercred) {
  var user = usercred.user;
  console.log("Account linking success", user);
}, function(error) {
  console.log("Account linking error", error);
});

您可以检查文档中是否有其他方法链接多个提供程序：

https://firebase.google.com/docs/auth/web/account-linking

https://firebase.google.com/docs/auth/web/account-linking#link-email-address-and-password-credentials-to-a-user-account

如何在Firebase中使用电子邮件和电话进行身份验证？
