无论做什么，都请记得那是为自己而做，那就毫无怨言。不刻意的装饰自己，那些都是给别人看的，而真的在乎我的人不会在乎这些。
从angular 4.3.0 以后的版本开始使用httpclient，替换了之前的http，引用的包路径已经变为了angular/common/http了
一个基础的 httpclient 样例
import { Injectable } from '@angular/core';
import { HttpClient, HttpResponse } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import { HttpDefaultOptions } from './http.default.options';
@Injectable()
export class Service {
private static METHOD_DELTE = 'DELETE';
private static METHOD_POST = 'POST';
private static METHOD_GET = 'GET';
private static METHOD_PUT = 'PUT';
constructor(private httpClient: HttpClient) {
}
/**
* 将数据上传
* @param data
* @param {Function} func
*/
uploadDataPost(data: any, func: Function) {
let url = '/api/test';
this.apiPost(url, data)
.subscribe((response: HttpResponse) => {
func(response);
}, error => {
func(undefined);
});
}
/**
* 返回json 格式的obj 对象
* @param url
* @param body
* @param urlSearchParams
* @returns {Observable<{}>}
*/
apiPost(url, body, urlSearchParams?: any): Observable<{}> {
let options = {
body: body ? body : null,
params: urlSearchParams,
responseType: 'json'
};
return this.httpClient.request(Service.METHOD_POST, url, options);
}
/**
* 返回一个obj 对象
* @param url
* @param urlSearchParams url 的查询参数
* @returns {Observable<{}>}
*/
apiGet(url, urlSearchParams?: any): Observable<{}> {
let options = {
params: urlSearchParams,
responseType: 'json'
};
return this.httpClient.request(Service.METHOD_GET, url, options);
}
}
本文angular5 httpclient的示例实战到此结束。被嘲笑的梦想就越有实现的价值。小编再次感谢大家对我们的支持！
