HttpUrlConnection getOutputStream（）抛出java.net.SocketException：服务器上的文件意外结束

Question

我正在尝试使用Java代码调用REST Web服务。

我可以通过Rest Client Postman来执行它。

我的代码：

    URL url = new URL(appURL);
    httpCon = (HttpURLConnection) url.openConnection();
    httpCon.setRequestMethod("POST");
    httpCon.setDoInput(true);
    httpCon.setUseCaches(false);
    httpCon.setAllowUserInteraction(false);
    httpCon.setDoOutput(true);
    httpCon.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
    httpCon.setRequestProperty("Host", "www.astecanalytics.com");
    httpCon.setRequestProperty("Expect", "100-continue");

    OutputStream outstream = httpCon.getOutputStream();

我得到以下错误：

java.net.SocketException: Unexpected end of file from server
    at sun.net.www.http.HttpClient.parseHTTPHeader(HttpClient.java:772)
    at sun.net.www.http.HttpClient.parseHTTP(HttpClient.java:633)

    at com.ktt.business.keywords.webservice.ExecuteWebServiceKeyword.postHTTPRequestAndGetRespone(ExecuteWebServiceKeyword.java:618)

有人可以帮忙吗？

由于服务器的响应正常，因此服务器端没有问题。 将通过Rest Client发送的请求正文与从代码发送的请求正文进行比较。 然后尝试映射。
