角：不能将类型'void'的参数分配给类型'（value：UserCredential）=> UserCredential | PromiseLike <usercredential>'

Question

注册成功后，我尝试启动一种新方法。不幸的是，webstorm显示此错误：

  

不能将类型'void'的参数分配给类型'（value：UserCredential）=> UserCredential | PromiseLike'。

这是我的代码：

@Injectable()
export class AuthService {

    constructor(private router: Router) {}

    signUp(email: string, password: string) {

        firebase.auth().createUserWithEmailAndPassword(email, password)
            .then(this.goPersonalData());
    }

    login(email: string, password: string) {
        firebase.auth().signInWithEmailAndPassword(email, password)
            .then(success => console.log('its working todo next, goto Main PAge'));
    }

    goPersonalData() {
        this.router.navigate(['/personalData']);
    }
}

它发生在这一行：

      this.goPersonalData()

Answer 1

将signup方法修改为：

@Injectable()
export class AuthService {

    ...

    signUp(email: string, password: string) {

        firebase.auth().createUserWithEmailAndPassword(email, password)
            .then((res) => {
                this.goPersonalData();
            });
    }

    ...
}
