在 app.module.ts 中引入 HttpClientModule 并注入
import {HttpClientModule} from '@angular/common/http';
imports: [
BrowserModule,
HttpClientModule
]
Angular get 请求数据
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) { }
get 请求数据
var api = "http://a.itying.com/api/productlist";
this.http.get(api).subscribe(response => {
console.log(response);
});
Angular post 提交数据
在用到的地方引入 HttpClient、HttpHeaders 并在构造函数声明 HttpClient
import {HttpClient,HttpHeaders} from "@angular/common/http";
constructor(public http:HttpClient) { }
post 提交数据
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
在 app.module.ts 中引入 HttpClientModule、HttpClientJsonpModule 并注入
import {HttpClientModule,HttpClientJsonpModule} from
'@angular/common/http';
imports: [
BrowserModule,
HttpClientModule,
HttpClientJsonpModule
]
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) { }
jsonp 请求数据
var api = "http://a.itying.com/api/productlist";
this.http.jsonp(api,'callback').subscribe(response => {
console.log(response);
});
Angular 中使用第三方模块 axios 请求数据
安装 axios
cnpm install axios --save
用到的地方引入 axios
import axios from 'axios';
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
});
封装service作为http服务
import { Injectable } from '@angular/core';
import axios from 'axios';
@Injectable({
providedIn: 'root'
})
export class HttpserviceService {
constructor() { }
axiosGet(api){
return new Promise((resolve,reject)=>{
axios.get(api)
.then(function (response) {
// handle success
resolve(response)
});
})
}
}
