最近需要一个短信业务的接口，发送http请求来发送短信，因为网上给的代码混乱不统一，自己实现了一个，以便自己以后自己使用java发送http请求。

import org.apache.commons.httpclient.Header;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.PostMethod;/*** Created by yan on 2016/8/5.*/
public class HttpUtil {public static void main(String[] args){HttpUtil httpUtil = new HttpUtil();httpUtil.SendMessage("http://sms.coocaatv.com/sms/down/",httpUtil.getXmlInfo("13012345678","发送的信息"));}public void SendMessage(String url,String xmlFilename){HttpClient httpClient = new HttpClient();PostMethod postMethod = new PostMethod(url);postMethod.addRequestHeader("Content-Type", "application/x-www-form-urlencoded;charset=utf-8");postMethod.setRequestBody(xmlFilename);try {httpClient.executeMethod(postMethod);Header[] headers = postMethod.getResponseHeaders();int statusCode = postMethod.getStatusCode();System.out.println("code:"+statusCode);for(Header h : headers){System.out.println(h.toString());}String result = new String(postMethod.getResponseBodyAsString().getBytes("GBK"));//打印返回的结果System.out.println(result);postMethod.releaseConnection();}catch (Exception e){e.printStackTrace();}}public String getXmlInfo(String phonenumber,String message) {StringBuilder sb = new StringBuilder();//可能每个运营商要求的发送后缀格式不一致，需要自己判断手机号int state = matchesPhoneNumber(phonenumber);if(state==2){message = message+"[]";}else{message = message+"【】";}sb.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");sb.append("<data>");sb.append("</data>");return sb.toString();}public static int matchesPhoneNumber(String phone_number) {//移动String cm = "^((13[4-9])|(147)|(15[0-2,7-9])|(18[2-3,7-8]))\\d{8}$";//联通String cu = "^((13[0-2])|(145)|(15[5-6])|(186))\\d{8}$";//电信String ct = "^((133)|(153)|(18[0,9]))\\d{8}$";int flag = 0;if (phone_number.matches(cm)) {flag = 1;} else if (phone_number.matches(cu)) {flag = 2;} else if (phone_number.matches(ct)) {flag = 3;} else {flag = 4;}return flag;}}
