如何使用Angular 2在http服务中发送数据

问题描述

我有一个URL数组，我需要将它们作为http服务url路径发送，并根据响应类型生成结果.示例数组如下.

I have an array of urls which I need to send as the http service url path and generate the result based on the response type. the example array is as below.

this.urlArray = ["www.test.com","www.test2.com"];

我遍历数组并生成div，并将URL作为参数发送到http服务，并根据请求类型(例如超时")，成功和错误将更改div的颜色.谁能告诉我该怎么做.

I iterate over the array and generate div and will send the url to http service as parameter and based on the request type like "time-out", success and error will change the div color. Can anybody please tell how should I proceed.

  addHero (name: string): Observable<Hero> {
    let headers = new Headers({ 'Content-Type': 'application/json' });
    let options = new RequestOptions({ headers: headers });

    return this.http.post(this.heroesUrl, /*{ name }*/ this.urlArray, options)
                    .map(this.extractData)
                    .catch(this.handleError);
  }
