Angular get 请求数据
Angular5.x 以后 get、post 和和服务器交互使用的是 HttpClientModule 模块。
- 1、在 app.module.ts 中引入 HttpClientModule 并注入
import {HttpClientModule} from '@angular/common/http';
imports: [ BrowserModule, HttpClientModule ]
- 2、在用到的地方引入 HttpClient 并在构造函数声明
import {HttpClient} from "@angular/common/http";
constructor(public http:HttpClient) { }
- 3、get 请求数据
var api = "http://a.itying.com/api/productlist";
this.http.get(api).subscribe(response => { console.log(response); });
- 4、POST提交
const httpOptions = { headers: new HttpHeaders({ 'Content-Type': 'application/json' }) };
var api = "http://127.0.0.1:3000/doLogin";
this.http.post(api,{username:'张三',age:'20'},httpOptions).subscribe(response => {
console.log(response);
});
Angular Jsonp 请求数据
- 1、在 app.module.ts 中引入 HttpClientModule、HttpClientJsonpModule 并注入
import {HttpClientModule,HttpClientJsonpModule} from '@angular/common/http';
imports: [ BrowserModule, HttpClientModule, HttpClientJsonpModule ]
- 2、在用到的地方引入 HttpClient 并在构造函数声明
import {HttpClient} from "@angular/common/http";
constructor(public http:HttpClient) { }
- 3、jsonp 请求数据
var api = "http://a.itying.com/api/productlist";
this.http.jsonp(api,'callback').subscribe(response => { console.log(response); });
使用axios
1、安装 axios
cnpm install axios --save
2、用到的地方引入 axios
import axios from 'axios';
3、看文档使用
axios.get('/user?ID=12345') .then(function (response) {
// handle success console.log(response);
}).catch(function (error) {
// handle error console.log(error);
}).then(function () {
// always executed
});
