Android通过post请求发送一个xml，解析返回xml数据

 

工作的时候需要往后台发送一个post数据请求

 

其中发送的xml数据为：

<?xml version = “1.0” ?> 
<SSOMessage version=”1.0”>
<SSOParas>
<SeqID>SeqID</SeqID> 
<CommandID>CommandID</CommandID> 
<MSISDN>ABSCDSDF</MSISDN>
<ChargeMSISDN>ChargeMSISDN</ChargeMSISDN>
<SPID>SPID</SPID>
<Code> Code </ Code >
< IDtype > IDtype 0</ IDtype >
<ID> ID 0</ID>
</SSOParas>
</SSOMessage>

返回的xml数据为：

<?xml version = “1.0” ?> 
<SSOMessage version=”1.0”> 
<SSOParas> 
<SeqID>SeqID</SeqID> 
<ResultCode>ResultCode0</ResultCode>
</SSOParas>
</SSOMessage>

然后进行解析，代码如下，参考一下，对于以后再做post请求的时候，做参考

class httpThread implements Runnable {

    /* (non-Javadoc)
     * @see java.lang.Runnable#run()
     */
    @Override
    public void run() {
        // TODO Auto-generated method stub
        //组建xml数据
        StringBuilder xml = new StringBuilder();
        xml.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
        xml.append("<SSOMessage version=\"1.0\">");
        xml.append("<SSOParas>");
        xml.append("<SeqID>13333333333</SeqID>");
        xml.append("<CommandID>1</CommandID>");
        xml.append("<MSISDN>1333333333</MSISDN>");
        xml.append("<ChargeMSISDN>1333333333</ChargeMSISDN>");
        xml.append("<SPID>3510127</SPID>");
        xml.append("<Code></Code>");
        xml.append("<IDtype>0</IDtype>");
        xml.append("<ID>135000000000000216559</ID>");
        xml.append("</SSOParas>");
        xml.append("</SSOMessage>");

        try {
            byte[] xmlbyte = xml.toString().getBytes("UTF-8");
            
            System.out.println(xml);

            URL url = new URL("http://118.85.194.28:8080/sotpms_server/GetSSOMessage");
            
            
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setConnectTimeout(5000);
            conn.setDoOutput(true);// 允许输出
            conn.setDoInput(true);
            conn.setUseCaches(false);// 不使用缓存
            conn.setRequestMethod("POST");
            conn.setRequestProperty("Connection", "Keep-Alive");// 维持长连接
            conn.setRequestProperty("Charset", "UTF-8");
            conn.setRequestProperty("Content-Length",
                    String.valueOf(xmlbyte.length));
            conn.setRequestProperty("Content-Type", "text/xml; charset=UTF-8");
            conn.setRequestProperty("X-ClientType", "2");//发送自定义的头信息

            conn.getOutputStream().write(xmlbyte);
            conn.getOutputStream().flush();
            conn.getOutputStream().close();


            if (conn.getResponseCode() != 200)
                throw new RuntimeException("请求url失败");

            InputStream is = conn.getInputStream();// 获取返回数据
              

            // 使用输出流来输出字符(可选)
            ByteArrayOutputStream out = new ByteArrayOutputStream();
            byte[] buf = new byte[1024];
            int len;
            while ((len = is.read(buf)) != -1) {
                out.write(buf, 0, len);
            }
            String string = out.toString("UTF-8");
            System.out.println(string);
            out.close();
                 
                     
            // xml解析
            String version = null;

            XmlPullParser parser = Xml.newPullParser();
            try {
