android - How can I POST "string request" and get data? -

i have tried application on android 23 , stuck somewhere.

i have request not url format!!!! string format. post on server , return data.

for example url is=http://api.someurl/app_dev.php/tr/content

and need post string parameter

 {   "command":"read",   "ctrl":"summaryofday",   "data":{"date":"08.04.2016"},   "order":null,   "limit":null  } 

and should return json data. because this request search parameter !

my code is

httpurlconnection connection=null; bufferedreader reader=null;  try {     url url=new url(params[0]);     connection=(httpurlconnection)url.openconnection();      inputstream stream=connection.getinputstream();     reader=new bufferedreader(new inputstreamreader(stream));     stringbuffer buffer=new stringbuffer();     string line = "";      while ((line = reader.readline())!= null){         buffer.append(line);     }     string sjson = buffer.tostring();     jsonobject mjson = new jsonobject(sjson);     } catch (malformedurlexception e) {     e.printstacktrace(); } catch (ioexception e) {     e.printstacktrace(); } catch (jsonexception e) {     e.printstacktrace(); }  return null; 

so how can post these string , json date.

regards.

i have solved :)

searched many hours, tried many thinks , got :)

if have parameter json data example have weather apı , need somewhere weather.

this way explain how sending string request on api url , json data.

for example request is,

 {   "command":"read",   "ctrl":"summaryofday",   "data":{"date":"08.04.2016"},   "order":null,   "limit":null  } 

i need info data.

after code work.

private class downloadapi extends asynctask<string,string,string>{      string datestr;      progressdialog pdialog;     @override     protected void onpreexecute() {         super.onpreexecute();          pdialog = new progressdialog(mainactivity.this);         pdialog.setmessage("akış bilgileri getiriliyor...");         pdialog.setindeterminate(true);         pdialog.setcancelable(false);         pdialog.show();     }      @override     protected string doinbackground(string... params) {         httpurlconnection connection = null;         bufferedreader reader = null;          date timenow = new date();         dateformat df = new simpledateformat("dd.mm.yyyy");          datestr=df.format(timenow)+"";          string data="{\"command\":\"read\",\"ctrl\":\"summaryofday\",\"data\":{\"date\":\""+datestr+"\"},\"order\":null,\"limit\":null}";           try {             url url = new url(params[0]);             connection = (httpurlconnection) url.openconnection();             connection.setdooutput(true);             connection.setrequestproperty("content-type", "application/json");             connection.setrequestproperty("accept", "application/json");             connection.setrequestmethod("post");             connection.connect(); // still works without line, don't know why               outputstream os = connection.getoutputstream();             bufferedwriter writer = new bufferedwriter(new outputstreamwriter(os, "utf-8"));             writer.write(data);             writer.close();             os.close();              inputstream stream = connection.getinputstream();              reader = new bufferedreader(new inputstreamreader(stream));              stringbuffer buffer = new stringbuffer();              string line = "";             while ((line = reader.readline())!= null){                 buffer.append(line);             }             string sjson = buffer.tostring();             jsonobject mjson = new jsonobject(sjson);              return sjson;          } catch (malformedurlexception e) {             e.printstacktrace();         } catch (ioexception e) {             e.printstacktrace();         } catch (jsonexception e) {             e.printstacktrace();         } {             if(connection != null) {                 connection.disconnect();             }             if(reader != null){                 try {                     reader.close();                 } catch (ioexception e) {                     e.printstacktrace();                 }             }         }         return null;     }      @override     protected void onpostexecute(string result) {         super.onpostexecute(result);         pdialog.dismiss();         mtext.settext(result.tostring());     } } 

thanks helped me :)
