是否可以使用HttpClient下载PDF等文件？

Question

我在这里找到了一些关于如何下载文件的例子,但是大多数文件似乎都在使用HttpURLConnection.是否可以使用HttpClient下载文件？

Answer 1

使用httpclient非常简单.这是教程的链接.

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.
}
