HTTP接口POST方式调用实例

客户端请求HTTP接口（POST）：

方法一：

String url ="http://IP:端口/usi-sep/services/SqmScapService?wsdl";//请求接口地址

URL wsUrl = new URL(url);

HttpURLConnection conn = (HttpURLConnection) wsUrl.openConnection();

conn.setDoInput(true);

conn.setDoOutput(true);

conn.setRequestMethod("POST");

conn.setConnectTimeout(5*1000);

conn.setRequestProperty("Content-Type", "text/xml;charset=UTF-8");

conn.setRequestProperty("SOAPAction",

url);

String req = "<soapenv:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:sqm=\"http://www.chinatelecom.com/oss/sqmws/services/SqmService\">";//命名空间

req+="<soapenv:Header>";

req+="<Esb>";

req+="<Route>";

req+="<EsbId/>";

req+="</Route>";

req+="<Business/>";

req+="</Esb></soapenv:Header>";

req+="<soapenv:Body>";

req+="<sqm:platformQry soapenv:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\">";//platformQry方法名

req+="<xmlInfo xsi:type=\"soapenc:string\" xmlns:soapenc=\"http://schemas.xmlsoap.org/soap/encoding/\"><![CDATA[" ;

req+="<root>";

req+="<interfaceCode>IPTV_zzyw_select</interfaceCode>";

req+="<queryInfo>"; //

req+="<attrInfo>"; //

req+="<attrCode>iptv_num</attrCode>"; //

req+="<attrValue>12345678@ott</attrValue>"; //

req+="</attrInfo>";

req+="</queryInfo>";

req+="</root>";

req+="]]></xmlInfo>";

req+="</sqm:platformQry>";

req+="</soapenv:Body>";

req+="</soapenv:Envelope>";

PrintStream ps = new PrintStream(conn.getOutputStream(),true,"utf-8");

ps.print(req);

ps.close();

BufferedReader bReader = new BufferedReader(new InputStreamReader(conn.getInputStream(),"UTF-8"));

String line, resultStr = "";

while (null != (line = bReader.readLine())) {

resultStr += line;

}

bReader.close();

String xml =StringEscapeUtils.unescapeXml(resultStr);//把xml还原

/***********************************************开始解析xml报文*******************************************/

Map map;

try {

map = CommonService.parseXmlToMap(xml);//见其他commonService文件

System.out.println("返回解析xml"+map);

List response =(List) map.get("response");

String result = (String) ((Map)response.get(0)).get("result");

String desc = (String) ((Map)response.get(0)).get("desc");//返回信息

List record =(List) map.get("record");

for(int i=0;i<record.size();i++){

String ZD = (String) ((Map)record.get(i)).get("ZD");

String TYPE = (String) ((Map)record.get(i)).get("TYPE");

String IPTV_NUM = (String) ((Map)record.get(i)).get("IPTV_NUM");

String BEGINTIME = (String) ((Map)record.get(i)).get("BEGINTIME");

String CONTENTNAME = (String) ((Map)record.get(i)).get("CONTENTNAME");

System.out.println("******************************************"+i+"***********************************");

System.out.println("ZD++++:"+ZD);

System.out.println("TYPE++++:"+TYPE);

System.out.println("IPTV_NUM++++:"+IPTV_NUM);

System.out.println("BEGINTIME++++:"+BEGINTIME);

System.out.println("CONTENTNAME++++:"+CONTENTNAME);

}

} catch (Exception e) {

// List<NameValuePair> list = new ArrayList<>();

list.add(new BasicNameValuePair("sign",sign));

list.add(new BasicNameValuePair("page",page));

try {

post.setEntity(new UrlEncodedFormEntity(list));

CloseableHttpResponse response;

response = client.execute(post);

resultString=EntityUtils.toString(response.getEntity());

} catch (UnsupportedEncodingException e) {
