Question

我需要向Web服务发送xml请求并接受来自该Web服务的xml响应。

以下是代码：

public static void main(String[] args) throws IOException {

        String url ="http://XX.XXX.X.XX:80/test";
        String urlParameters = "";
        StringBuilder test = new StringBuilder(768);

        test.append("<?xml version='1.0'?>\n"+
    "<!DOCTYPE COMMAND PUBLIC '-//Ocam//DTD XML Command 1.0//EN' 'xml/command.dtd'>\n"+
                "<COMMAND>\n"+

                "<TYPE>EXUSRBALREQ</TYPE>\n"+
                "<DATE>14-03-17</DATE>\n"+
"<EXTNWCODE>MD</EXTNWCODE>\n"+
"<MSISDN>57625960</MSISDN>\n"+
"<PIN>47565</PIN>\n"+
"<LOGINID></LOGINID>\n"+
"<PASSWORD></PASSWORD>\n"+
"<EXTCODE>AD10001</EXTCODE>\n"+
"<EXTREFNUM>12345</EXTREFNUM>\n"+               
                "</COMMAND>\n");

        System.out.println(test);

        URL obj = new URL(url);
        HttpURLConnection con = (HttpURLConnection) obj.openConnection();
        con.setRequestMethod("POST");
        con.setRequestProperty("Content_Type", "application/xml");          
        con.setDoOutput(true);
        DataOutputStream wr = new DataOutputStream(con.getOutputStream());
        wr.writeBytes(urlParameters);
        wr.flush();
        wr.close();

        int responseCode = con.getResponseCode();
        System.out.println("Sending post on the URL"+url);      
        BufferedReader in = new BufferedReader(
                new InputStreamReader(con.getInputStream(),"UTF-8"));
        String inputLine;
        StringBuffer response = new StringBuffer();     
        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }           
        in.close();

        System.out.println(responseCode);
        System.out.println(response);


    }

每当我运行应用程序时，我都会获得200状态，但下面是我得到的响应

响应：

Sending post on the URLhttp://XXX.XXX.X.XX:80/test
200
mclass^2&pid^61:6002:Your request is invalid.  Please call 8900

有人可以帮助我。

此致

Answer 1

您的代码汇总要在名为StringBuilder的{{1}}中发送的XML。

但是，您实际上从未发送test的内容，因此服务器不接收XML也就不足为奇了。请解决这个问题。

请参阅示例Sending HTTP POST Request In Java，了解如何使用Java发送POST请求。
