angular - 错误 TS2345：类型为“OperatorFunction”的参数' 不能分配给 'OperatorFunction 类型的参数'

Question

我是 Angular 的新手。

我怎么解决这个问题？

我已经安装Angular CLI: 11.0.7并Node: 12.18.4

错误：

错误：src/app/_services/account.service.ts:19:7 - 错误 TS2345：“OperatorFunction<User, void>”类型的参数不可分配给“OperatorFunction<Object, void>”类型的参数。“对象”类型可分配给极少数其他类型。您的意思是改用“任何”类型吗？“对象”类型缺少“用户”类型的以下属性：用户名、令牌

 19       map((response: User) => {
          ~~~~~~~~~~~~~~~~~~~~~~~~~
 20         const user = response;
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
...
 24         }
    ~~~~~~~~~
 25       })
    ~~~~~~~~

account.service.ts

import { HttpClient } from '@angular/common/http';
import { Injectable } from '@angular/core';
import {map} from 'rxjs/operators';
import { User } from '../_models/user';
import { ReplaySubject } from 'rxjs';


export class AccountService {
  baseUrl = 'https://localhost:5001/api/';
  private currentUserSource = new ReplaySubject<User>(1);
  currentUser$ = this.currentUserSource.asObservable();

  constructor(private http: HttpClient) { }

  login(model: any) {
    return this.http.post(this.baseUrl + 'account/login', model).pipe(
      map((response: User) => {
        const user = response;
        if (user) {
          localStorage.setItem('user', JSON.stringify(user));
          this.currentUserSource.next(user);
        }
      })
    )
  }
}

用户.ts

export interface User{
    username: string;
    token: string;
}

你需要投 http.post 返回

  login(model: any) {
    //-------------- here ⇊⇊ ------
    return this.http.post<User>(this.baseUrl + 'account/login', model).pipe(
      map((user : User) => {
        if (user) {
          localStorage.setItem('user', JSON.stringify(user));
          this.currentUserSource.next(user);
        }
      })
    )
  }
