Swift3 iOS -Firebase FIREmailPasswordAuthProvider不工作 [英] Swift3 iOS -Firebase FIREmailPasswordAuthProvider Not Working

问题描述

我刚刚将我的Firebase Cocoapods从3.15.0升级到4.0.4，并将FirebaseAuth Cocoapods从3.1.1升级到4.0.0。我使用电子邮件和放大器;密码来验证用户。当用户更改他们的电子邮件时，我在下面使用这个方法，一切工作正常：

$ p $ FIREmailPasswordAuthProviderID.credential（withEmail：emailTextField。 text !, password：passwordTextField.text！）


现在我更新了错误信息

类型'String'的值没有成员'凭证'

我查看了

$

 FIREmailAuthProviderID.credential（withEmail： emailTextField.tex t !,密码：passwordTextField.text！）
  

字符串'没有成员'凭证'

我的原始代码

 导入Firebase 
导入FirebaseAuth 
 
让用户：用户？ 
 
让凭证= FIREmailPasswordAuthProviderID.credential（withEmail：emailTextField.text !,密码：passwordTextField.text！）
 
如果let user = user {
 user.reauthenticate （with：credential，completion：{
（error）in 
 if error！= nil {
 //...do something 
 return 
} 
 //... do something else 
}）
} 
  

我做错了什么？

解决方案

FIREmailAuthProviderID 是一个包含auth提供者id的常量，并且是一个字符串（在FB 4中为EmailAuthProviderID）。没有凭证功能，这就是为什么你得到这个错误。

这是一个链接到 Firebase 4移植指南

新格式（以及正确的函数调用）是
$ b

EmailAuthProvider.credential（带电子邮件：字符串，密码：
字符串） - > AuthCredential

I just upgraded my Firebase Cocoapods from 3.15.0 to 4.0.4 and FirebaseAuth Cocoapods from 3.1.1 to 4.0.0.

I'm using email & password to authenticate users. When a user changes their email I was using this method below and everything was working fine:

FIREmailPasswordAuthProviderID.credential(withEmail: emailTextField.text!, password: passwordTextField.text!)

Now that I updated I get the error message

Value of type 'String' has no member 'credential'

I looked on the docs and it said to use the method below:

The problem is I get the same exact error:

FIREmailAuthProviderID.credential(withEmail: emailTextField.text!, password: passwordTextField.text!)

Value of type 'String' has no member 'credential'

My original code below

import Firebase
import FirebaseAuth

let user: User?

let credential = FIREmailPasswordAuthProviderID.credential(withEmail: emailTextField.text!, password: passwordTextField.text!)

        if let user = user{
            user.reauthenticate(with: credential, completion: {
                (error) in
                if error != nil{
                    //...do something
                    return
                }
                //...do something else
            })
        }

What am I doing wrong?

解决方案

Hold up

FIREmailAuthProviderID is a constant that contains the auth providers id and is a string (which is EmailAuthProviderID in FB 4). There is no credential function which is why you are getting that error.

Here's a link to the Firebase 4 Migration Guide

The new format (and the correct function call) is

EmailAuthProvider.credential(withEmail email: String, password: String) -> AuthCredential
