我正在尝试通过在headers
中传递一些values
来进行http get()
请求,现在我正在这样替换headers
:
import { HttpClient, HttpHeaders } from '@angular/common/http';
import { Injectable } from '@angular/core';
import {ICustomer} from 'src/app/models/app-models';
@Injectable({
providedIn: 'root'
})
export class MyService {
private baseUrl = '....api url....';
public authKey = '....auth_key......';
constructor(private http: HttpClient) { }
public async AllCustomers(): Promise<ICustomer[]> {
const apiUrl = `${this.baseUrl}/customers`;
return this.http.get<ICustomer[]>(apiUrl ,
{headers: new HttpHeaders({Authorization: this.authKey})}).toPromise();<=====
}
}
当我这样替换标题时:
headers: new HttpHeaders({Authorization: this.authKey})
默认头部值(即Content-Type:application/json)将被上述标题替换。
public async AllCustomers(): Promise<ICustomer[]> {
const apiUrl = `${this.baseUrl}/courses`;
const headers = new HttpHeaders();
headers.append('Authorization', this.authKey);
headers.append('x-Flatten', 'true');
headers.append('Content-Type', 'application/json');
return this.http.get<ICustomer[]>(apiUrl).toPromise();
}
我的方法有什么问题,我是angular
的新手,需要帮助吗?
