1、直接建一个工具类放入即可

/**
 * 发送https请求共用体 
 */
public  static jsonobject  sendpost(string url,string parame,map<string,object> pmap) throws ioexception, keymanagementexception, nosuchalgorithmexception, nosuchproviderexception{
    // 请求结果
    jsonobject json = new jsonobject();
    printwriter out = null;
    bufferedreader in = null;
    string result = "";
    url realurl;
    httpsurlconnection conn;
    string method = "post";
    //查询地址
    string querystring = url;
    //请求参数获取
    string postpar = "";
    //字符串请求参数
    if(parame!=null){
        postpar = parame;
    }
    // map格式的请求参数
    if(pmap!=null){
        stringbuffer mstr = new stringbuffer();
        for(string str:pmap.keyset()){
            string val = (string) pmap.get(str);
            try {
                val=urlencoder.encode(val,"utf-8");
            } catch (unsupportedencodingexception e) {
                e.printstacktrace();
            }
                mstr.append(str+"="+val+"&");
        }
        // 最终参数
        postpar = mstr.tostring(); 
        int lasts=postpar.lastindexof("&");
        postpar=postpar.substring(0, lasts);
    }
    if(method.touppercase().equals("get")){
        querystring+="?"+postpar;
    }
    sslsocketfactory  ssf= httpsclientutils.getssfactory();
    try {
        realurl= new url(querystring);
        conn = (httpsurlconnection)realurl.openconnection();
        conn.setsslsocketfactory(ssf);

            conn.setdoinput(true);
            conn.setusecaches(false);
            out = new printwriter(conn.getoutputstream());
            out.print(postpar);
            out.flush();
        }else{
            conn.connect();
        }
        in = new bufferedreader(

        string line;
        while ((line = in.readline()) != null) {
            result += line;
        }
        json = jsonobject.fromobject(result);
    }finally {
        try {
            if (out != null) {
