HTTP Request with JSON body

Processing Libraries
1

Hello, I’m working with the TVDB API but I’m having trouble getting the access token as I normally do.

This is what the documentation says:

Authentication
Authentication to use the API is similar to the How-to section above. Users must POST to the /login route with their API key and credentials in the following format in order to obtain a JWT token.
{“apikey”:“APIKEY”,“username”:“USERNAME”,“userkey”:“USERKEY”}

And this is my code (I’m using @shiffman and @runemadsen 's library)

PostRequest post = new PostRequest("https://api.thetvdb.com/login");
post.addHeader("Content-Type", "application/json");
post.addHeader("Accept", "application/json");
post.addData("json", "{\"apikey\":\"APIKEY\",\"username\":\"USERNAME\",\"userkey\":\"USERKEY\"}");

but it’s not working.

I also tried:

post.addData("apikey", "APIKEY");
post.addData("username", "USERNAME");
post.addData("userkey", "USERKEY");

I think I have add the json to the “body” of the POST request but I can’t figure out how.

Thanks!

I figure out a solution:

  1. I downloaded the jar files of the Apache HTTPComponents library (on which HTTP Requests for Processing is based on) and added to my sketch’s folder

  2. I built an HTTP Request like this (following the examples on the website):

String authentication = "{\"apikey\":\"APIKEY\",\"username\":\"USERNAME\",\"userkey\":\"USERKEY\"}";

HttpClient httpClient = HttpClientBuilder.create().build(); //Use this instead 

try {
    HttpPost request = new HttpPost("https://api.thetvdb.com/login");
    StringEntity params =new StringEntity(authentication);
    request.addHeader("content-type", "application/json");
    request.setEntity(params);
    HttpResponse response = httpClient.execute(request);
    HttpEntity entity = response.getEntity();
    JSONObject json = parseJSONObject(EntityUtils.toString(entity));
    println(json.getString("token"));
    //handle response here...

}catch (Exception ex) {

    //handle exception here

} finally {
    //Deprecated
    //httpClient.getConnectionManager().shutdown(); 
}

and it works.

Now I’m wondering if there’s a way to do it without importing the Apache’s library or to add this feature to the Processing’s library.
