响应如下:

</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());
}
我的回复是这样的.

我想要接受编码另一个标题作为帖子的一部分，我该如何添加它们?我相信它必须是发布请求的一部分，而不是 http 标头.
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 Header 的一部分，除了你误作为 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:
这里是如何使用 HTTP 客户端发送它:
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");
