将网页的HTML加载到字符串

问题描述

有没有一个简单的方法来做这个与 dart：io ？

Is there an easy way to do this with dart:io?

我看过HttpClient和HttpServer，但我没有设法创建一个函数，可以采取一个URL并返回一个网站的标记的字符串。

I've looked into HttpClient and HttpServer, but I haven't managed to create a function that can take a URL and return a String of the website's markup.

String getHtml(String URL) {
...
}

推荐答案

我更喜欢这种方法使用 HttpBodyHandler 进行解析：

I prefer to use HttpBodyHandler for parsing:

  HttpClient client = new HttpClient();
  client.getUrl(Uri.parse("http://www.example.com/"))
  .then((HttpClientRequest response) => response.close())
  .then(HttpBodyHandler.processResponse)
  .then((HttpClientResponseBody body) => print(body.body));
