POST request with curl command for android using a JSON file -


i want send post request below curl command:

curl -d @request.json --header "content-type: application/json" https://www.googleapis.com/qpxexpress/v1/trips/search?key=my_api_key

i have created json file name request.json using below code:

public void createjsonfile(view view) throws ioexception, jsonexception {  jsonobject request_hdr = new jsonobject();  jsonobject request = new jsonobject();  jsonarray slice = new jsonarray();  jsonobject data = new jsonobject();   request.put("solutions", 20);  request.put("refundable", "false");   jsonobject addl_info = new jsonobject();  addl_info.put("adultcount",num_adult);  addl_info.put("infantinlapcount",num_infant);  addl_info.put("infantinseatcount", 0);  addl_info.put("childcount",0);  addl_info.put("seniorcount", 0);  request.put("passengers",addl_info);   data.put("origin",origin);  data.put("destination",destination);  data.put("date", start_date);  slice.put(data);  request.put("slice",slice);   request_hdr.put("request",request);   text = request_hdr.tostring();   fileoutputstream fileoutputstream = openfileoutput("request.json", mode_private);  fileoutputstream.write(text.getbytes());  fileoutputstream.close(); }

now how trigger post request curl command using json file created. have found couple of examples uses name-value pairs or json objects. how use json file instead of that. please me out.

thanks in advance!
