响应如下所示：
<?xml version="1.0" encoding="ISO-8859-1"?>
<stat directory="/182232">

</stat>
这是我的Java代码：
Here is My Java Code:
final HttpHost targetHost = new HttpHost("a.host.com", 80, "http");
final DefaultHttpClient httpClient = new DefaultHttpClient();
final Credentials credentials = new UsernamePasswordCredentials("user","pass");
httpClient.getCredentialsProvider().setCredentials(new AuthScope(targetHost.getHostName(), targetHost.getPort()), credentials);
final HttpPost httpPostRequest = new HttpPost("akamai/182232");
//Add your Data
final List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(6);
nameValuePairs.add(new BasicNameValuePair("Host: ", "a.host.com");
nameValuePairs.add(new BasicNameValuePair("Accept-Encoding: ", "identity"));
nameValuePairs.add(new BasicNameValuePair("Content-Length: ", "6"));
httpPostRequest.setEntity(new UrlEncodedFormEntity(nameValuePairs));
final HttpResponse response = httpClient.execute(targetHost, httpPostRequest);
if (response.getStatusLine().getStatusCode() != 200) {
throw new RuntimeException("Failed : HTTP error code : " + response.getStatusLine().getStatusCode());
}
My回复看起来像这样。
My response looks like this.

我想将Accept-Encoding另一个标题作为一部分的帖子，我该如何添加它们？它应该是我相信的帖子请求的一部分而不是http标题。
I want Accept-Encoding another headers as part of post, how do i add them ? It hast to be part of the post request i believe and not http header.
推荐答案
Accept-Encoding是HTTP标头的一部分，除了你错误地作为POST参数发送的参数：
Accept-Encoding is part of the HTTP Header, in addition to the parameters that you mistakenly sent as POST parameters:
以下是使用HTTP客户端发送它的方法：
Here is how to send it using HTTP Client:
httpPostRequest.setHeader("Content-Length", "6");
httpPostRequest.setHeader("Accept-Encoding", "identity");
httpPostRequest.setHeader("Host", "a.host.com");
