I’m trying to do a HTTP post request from openFrameworks and can’t seem to figure it out.
The info here doesn’t seem to work:
thank you, @underdoeg ! Never experimented with anything outside ofxAddons, but that was surprisingly easy. Cheers.
@bakercp ’s link is giving an error 404 on GitHub and @moebiussurfing code gives me a bunch of errors, copy pasting them below:
No type named 'DefaultClient' in namespace 'ofx::HTTP'
No type named 'BaseResponse' in namespace 'ofx::HTTP'; did you mean 'Response'?
No member named 'setPutFile' in 'ofx::HTTP::PostRequest'
Use of undeclared identifier 'putRequest'; did you mean 'postRequest'?
I’m being able to generate the JSON file that I need inside oF, save it to disk and now I need to send it as a http post request. I would need to read the http response as well.
Help would be appreciated
hey @ayruos ,
I do not tryed again recently but I was using 0.9.8 with the stable branch…
(It would be nice some good examples with authentication login and maybe a Google Cloud / Firebase example)

EDIT: is not what you are asking for… I can’t find the code I used for the API url POST…
I found the code I used to access Firebase server with the API / JSON with some help notes.

another way with CURL, better that your method writing the file btw.
// CURL:
// TODO: set time out and check available internet conection!
//std::string curlCommand = "curl -v -X POST -d "; //debug
std::string curlCommand = "curl -X POST -d ";
//-
// DATABASE JSON:
// std::string curlJson = "'{\"name\": \"seedName\",\"owner\": \"myUser\",\"xmlURL\": \"xmlURL\",\"pngURL\": \"pngURL\"}'";
//-
// API ENDPOINT:
std::string curlUrl = " 'https://xxxxx.firebaseio.com/seeds.json'";
std::string cmd = curlCommand + curlJson + curlUrl;
//EXAMPLE API CMD: "curl -v -X POST -d '{\"author\": \"alanisawesome\",\"title\": \"The Turing Machine\"}' 'https://xxxxx.firebaseio.com/seeds.json'";
string reply = ofSystem(cmd);
//std::cout << "==" << endl << reply << endl << "==" << std::endl;
// GET NEW SEED UUID:
//ofxJSONElement response;
ofxJSONElement jsonResponse;
jsonResponse = reply;
//cout << "JSON: " << jsonResponse << endl;
string responseName_UUID = jsonResponse["name"].asString();//UUID field
cout << endl;
cout << ">> CREATED NEW SEED! UUID: '" << responseName_UUID << "'" << endl;
