我有这个错误：

core.js:1440 ERROR Error: Uncaught (in promise): FirebaseError:     
[code=invalid-argument]: Invalid document reference. 
Document references must have an even number of segments, but users has 1

FirebaseError: Invalid document reference. 
Document references must have an even number of segments, but users has 1

这是我的函数：在 firebase.service.ts

  async login() {
    let u = await this.afAuth.auth.signInWithPopup(new firebase.auth.GoogleAuthProvider())
    console.log(u);
    return this.getUserData(u.user.email);
  }

  public updateUser(UserName,phone)
  { 
    this.userRef.doc(this.getEmail()).set({
     UserName:UserName,
     phone:phone, 
    });

    this.router.navigate(["home"]);
  }

在 login.component.ts 中：

login(){

  this.firebaseService.updateUser(this.UserName,this.phone);

}

在login.component.html中：

        <input type="text" [(ngModel)]="UserName" onsubmit="myFunction()" name="UserName"  pattern="[A-Za-z]{}" placeholder="UserName">
        <div id="UserName" style="color:transparent; display:none">
          The user name is required.
        </div>

        <input type="number" [(ngModel)]="phone" name="phone" placeholder="Phone number">
        <div id="PelephoneNumber" style="color:transparent; display:none">
            The phone is required.
          </div>
        <button (click)=login() type="Submit" class="Submit" id="login-button">Login</button>

    </form>
    </div>

有什么帮助吗？

【解决方案1】：

我认为您需要在这里分享更多代码。我们不知道 this.userRef 设置为... 不假设您设置正确，我将其写为：

this.fireStore.collection('users').doc(this.getUserEmail()).update({name:'John Doe'});

1.) 请注意，我使用的是 update，而不是 set。 Set 将使用您传递的任何新数据完全覆盖文档。我假设您想使用更新，因为您的函数名称称为“updateUser()”

2.) 我还假设 this.getUserEmail() 返回一个 string。 .doc() 方法需要一个与您尝试更新的文档的 ID 匹配的字符串。

如果您提供更多服务代码，我可能会提供更多帮助...
