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.setrequestproperty("content-type","application/x-www-form-urlencoded"); conn.setrequestproperty("accept", "*/*"); conn.setrequestproperty("connection", "keep-alive"); conn.setrequestproperty("user-agent", "mozilla/4.0 (compatible; msie 6.0; windows nt 5.1;sv1)"); if(method.touppercase().equals("post")){ conn.setdooutput(true); conn.setdoinput(true); conn.setusecaches(false); out = new printwriter(conn.getoutputstream()); out.print(postpar); out.flush(); }else{ conn.connect(); } in = new bufferedreader( new inputstreamreader(conn.getinputstream(),"utf-8")); string line; while ((line = in.readline()) != null) { result += line; } json = jsonobject.fromobject(result); }finally { try { if (out != null) { out.close(); } if (in != null) { in.close(); } } catch (ioexception ex) { ex.printstacktrace(); } } return json; }
