是否可以使用HttpClient下载PDF等文件？

Question

I found some examples here on how to download a file but most of them seem to be using HttpURLConnection. is it possible to download files with HttpClient?

Answer 1

Using httpclient is pretty easy. Here's a link to it's tutorial.

http://hc.apache.org/httpcomponents-client-ga/tutorial/html/fundamentals.html#d5e43

HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(urltofetch);
HttpResponse response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
if (entity != null) {
    long len = entity.getContentLength();
    InputStream inputStream = entity.getContent();
    // write the file to whether you want it.
}

您可以使用HttpURLConnection做的任何事情，通常更好，使用HttpClient查看有关文件传输的示例，您将看到如何做。
