Help with HTTP requests - POST

Processing Libraries
1

I need some help with rest api from Processing. I’m using HTTP Request for Processing library, but I can’t get addFile() to locate my image file. Image file is saved in data folder.

Error message received: “I/O exception (java.io.FileNotFoundException) caught when processing request: image_1.jpeg (The system cannot find the file specified)”

Library reference: HTTP-Requests-for-Processing/src/http/requests/PostRequest.java at master · runemadsen/HTTP-Requests-for-Processing · GitHub

API used: https://my.plantnet.org/

My code:

import http.requests.*;

public void setup() 
{
  size(400,400);
  smooth();
  
  File img = new File("image_1.jpeg");

  PostRequest post = new PostRequest("https://my-api.plantnet.org/v2/identify/all?api-key=MY_API_KEY_REMOVED");
  post.addFile("images", img);
  post.addData("organs", "['flower']");
  post.send();
  System.out.println("Reponse Content: " + post.getContent());
  System.out.println("Reponse Content-Length Header: " + post.getHeader("Content-Length"));
}

In my opinion the error occurs in this line and has nothing to do with the post request

Are you sure the file is in the sketch directory?

please try ....File(sketchPath("image_1.jpeg"));

(Also, maybe it’s jpg or JPEG, this is not always correctly shown by Windows)

Or use loadImage(...); instead of File

in combination with PImage img; ?

Using sketchPath() works!
Thank you, I appreciate it.
