我实施了firebase auth phone身份验证。 我想在使用verifyPhoneNumber之前通过身份验证表中的电话号码检查用户是否已经存在。
因为我有问题,如果用户已经存在于此表中,并且我使用带有现有电话号码的verifyPhoneNumber函数,则已向他发送短信。我想要做的是,如果用户已经存在于此表中,那么就不要发送他和短信并获得此用户!
confirmPhone = async (phoneNumber) => {
return new Promise((res, rej) => {
firebase.auth().verifyPhoneNumber(phoneNumber)
.on('state_changed', async (phoneAuthSnapshot) => {
console.log('phoneAUTH',phoneAuthSnapshot)
switch (phoneAuthSnapshot.state) {
case firebase.auth.PhoneAuthState.AUTO_VERIFIED:
console.log('PhoneAuthState.AUTO_VERIFIED',phoneAuthSnapshot)
await this.confirmCode(phoneAuthSnapshot.verificationId, phoneAuthSnapshot.code, phoneAuthSnapshot)
res(phoneAuthSnapshot)
break
case firebase.auth.PhoneAuthState.CODE_SENT:
console.log('code send',phoneAuthSnapshot)
// await userSettings.set(AUTH_KEYS.VERIFICATION_ID, phoneAuthSnapshot.verificationId)
UserStore.setVerificationId(phoneAuthSnapshot.verificationId)
res(phoneAuthSnapshot)
break
case firebase.auth.PhoneAuthState.AUTO_VERIFY_TIMEOUT: // or 'timeout'
console.log('AUTO_VERIFY_TIMEOUT',phoneAuthSnapshot)
UserStore.setVerificationId(phoneAuthSnapshot.verificationId)
res(phoneAuthSnapshot)
case firebase.auth.PhoneAuthState.ERROR:
console.log('APhoneAuthState.ERROR',phoneAuthSnapshot)
UserStore.setErrorConfirmationCode(phoneAuthSnapshot.error)
rej(phoneAuthSnapshot)
break
}
})
})
}
confirmCode = async (verificationId, code, phoneAuthSnapshot) => {
try{
const credential = await firebase.auth.PhoneAuthProvider.credential(UserStore.verificationId, code)
UserStore.setCodeInput(code)
UserStore.setUserCredentials(credential)
AppStore.setAlreadyRegister(true)
await this.authenticate(credential)
return credential
} catch(e){
throw new Error(e)
}
}
authenticate = async (credential) => {
await firebase.auth().signInAndRetrieveDataWithCredential(credential)
}

您可以在admin sdk中使用getUserByPhoneNumber()。但对于前端框架,我认为我们不喜欢这样,建议你在firestore中创建记录并检查相同的内容。
