尝试将 XML 发布到 HTTPS URL 时出现 HTTP 403 服务错误

Question

我正在尝试使用 Apache HttpClient 库编写一个小类，该类将向指定的 URL 发送 HTTPS 请求，发送一些 XML。当我运行代码时，我收到的 HTTP 状态行是“403 服务错误”。这是返回的完整错误 HTML：

$errorDump  java.net.SocketTimeoutException:Read timed out
$errorInfo  
$errorDump  java.net.SocketTimeoutException:Read timed out
$error  Read timed out
$localizedError Read timed out
$errorType  java.net.SocketTimeoutException
$user   
$time   2011-10-25 09:39:29 EDT
$error  Read timed out
$errorType  java.net.SocketTimeoutException

这是我正在使用的代码：

import java.io.ByteArrayInputStream;
import java.io.InputStreamReader;
import java.io.BufferedReader;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.InputStreamEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;

public class HttpXmlPost {

    public static void main(String[] args)
    {
        String url = "https://someurlhere.com";
        String xmlStr = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?><xmlTag></xmlTag>";

        String content = request(xmlStr, url);
        System.out.println(content);
    }

    private static String request(String xmlStr, String url) {
        boolean success = false;
        String content = "";

        HttpClient httpclient = new DefaultHttpClient();

        try {
            HttpPost httpPost = new HttpPost(url.trim());

            InputStreamEntity reqEntity = new InputStreamEntity(new ByteArrayInputStream(xmlStr.getBytes() ), -1);
            reqEntity.setContentType("application/xml");
            reqEntity.setChunked(true);

            httpPost.setEntity(reqEntity);

            System.out.println("Executing request " + httpPost.getRequestLine());
            HttpResponse response = httpclient.execute(httpPost);
            HttpEntity resEntity = response.getEntity();

            System.out.println("----------------------------------------");
            System.out.println(response.getStatusLine());
            if(response.getStatusLine().getStatusCode() == 200){
                success = true;
            }
            if (resEntity != null) {
                System.out.println("Response content length: " + resEntity.getContentLength());
                System.out.println("Chunked?: " + resEntity.isChunked());
            }

            BufferedReader reader = new BufferedReader(new InputStreamReader(resEntity.getContent()));
            StringBuilder buf = new StringBuilder();
            char[] cbuf = new char[ 2048 ];
            int num;

            while ( -1 != (num=reader.read( cbuf ))) {
                buf.append( cbuf, 0, num );
            }

            content = buf.toString();

            EntityUtils.consume(resEntity);
        } 
        catch (Exception e) {
            System.out.println(e);
        }
        finally {
            httpclient.getConnectionManager().shutdown();
        }

        return content;
    }
}

无论我传入什么 XML 似乎都不重要，无论如何它都会给出相同的错误。请注意，这实际上适用于某些 URL。例如，如果我输入 https://www.facebook.com，它就会通过。但是，它不适用于我指定的 URL。我认为这可能是一个证书问题，尝试添加一些代码来信任任何证书，似乎也不起作用，尽管我可能做错了。任何帮助表示赞赏。

基于 SocketTimeoutException 在响应 HTML 的第一行中，我猜测实现您要发布到的 URL 的处理程序的组件与生成响应数据所需的源系统存在一些连接问题。

基本上，问题似乎出在服务器上，而不是您的客户端上。
