我有以下代码来调用网址：http://10.105.0.120/24online/servlet/ClientRegistrationResponse?action=response&phone=919638983856&actioncode=0000
代码：
StringBuffer request=new StringBuffer();
request.append(xml);
URL url = new URL(url);
HttpURLConnection obj = null;
obj = (HttpURLConnection)url.openConnection(); //create a SSL connection object server-to-server
((URLConnection)obj).setDoInput(true);
((URLConnection)obj).setDoOutput(true);
((URLConnection)obj).setUseCaches(false);
// ((URLConnection)obj).setReadTimeout(10);
((URLConnection)obj).setRequestProperty("Content-Type","application/x-www-form-urlencoded");
obj.setRequestMethod("POST");
obj.setRequestProperty("charset", "US-ASCII");
//obj.setConnectTimeout(PropertyReader.IN_REQUEST_TIMEOUT);
//obj.setReadTimeout(PropertyReader.IN_REQUEST_TIMEOUT);
// Here the HTTPS request URL is created
DataOutputStream dataoutputstream = new DataOutputStream(((URLConnection)obj).getOutputStream());
dataoutputstream.writeBytes(request.toString()); //request
//dataoutputstream.flush();
dataoutputstream.close(); //connection closed
BufferedReader bufferedreader = new BufferedReader(new InputStreamReader(((URLConnection)obj).getInputStream()));
String res = "";
while ( (res = bufferedreader.readLine()) != null ) {
conresponse += res;
}
bufferedreader.close();
但是我收到了以下错误：
java.io.IOException: Server returned HTTP response code: 500 for URL: http://10.105.0.120/24online/servlet/ClientRegistrationResponse?action=response&phone=919638983856&actioncode=0000

出现此错误的原因是什么？就像我直接从浏览器调用URL一样，它的工作非常完美。
答案 0 :(得分：1)
有问题吗？
您向服务器发送了错误请求，并且它正在响应内部服务器错误（代码500）。合乎逻辑的做法是检查您的HTTP服务器日志（它是10. * IP地址，因此它是您本地的。）
此外，JDOM异常位于不同的线程中......您显示的代码中没有与JDOM相关的代码，并且异常堆栈跟踪没有以任何方式链接到具有500状态响应的IOException。或者，您忽略了状态500响应（IOException），然后期望同一线程中的JDOM代码解析来自服务器的（可能是空的）错误响应（毫无疑问会在过早结束时结束）文件）。
你需要：
