错误 TS2345：类型为“OperatorFunction”的参数<user, void> ' 不能分配给 'OperatorFunction 类型的参数<object, void> '</object,></user,>

Question

我是 Angular 的新手。

我怎么解决这个问题？

我已经安装了Angular CLI: 11.0.7和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;
}

Answer 1

你需要投 http.post return

  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);
        }
      })
    )
  }

Answer 2

http.post 可以转换为用户或任何

也试试

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

Typescript：类型'字符串| undefined' 不可分配给类型 'string'

"strict": true >>>> "strict": false
