Angular 2:如何访问 HTTP 响应正文? [英] Angular 2: How to access an HTTP response body?

问题描述

我在 Angular 2 中编写了以下代码:

I wrote the following code in Angular 2:

this.http.request('http://thecatapi.com/api/images/get?format=html&results_per_page=10').
      subscribe((res: Response) => {
        console.log(res);
      })

当我打印响应时，我在控制台中得到:

When I print the response I get in console:

我想在代码中访问响应中的正文字段.'body' 字段以下划线开头，这意味着它是一个私有字段.当我将其更改为 'console.log(res._body)' 时，出现错误.

I want to have access in the code to body field in the response. The 'body' field starts with an underscore, which means that it's a private field. When I change it to 'console.log(res._body)' I got an error.

你知道任何可以帮助我的 getter 函数吗?

Do you know any getter function that can help me here?

推荐答案

Both Request 和 Response 扩展 正文.要获取内容，请使用 text() 方法.

this.http.request('http://thecatapi.com/api/images/get?format=html&results_per_page=10')
    .subscribe(response => console.log(response.text()))

该 API 在 Angular 5 中已弃用.新的 HttpResponse 类有一个 .body() 方法.使用 {responseType: 'text'} 应该返回一个 String.

That API was deprecated in Angular 5. The new HttpResponse<T> class instead has a .body() method. With a {responseType: 'text'} that should return a String.
