DropBox Https Api Request : What should I do?

Questions & Answers
1

Hello everyone. I’m going crazy with DropBox Api Http
Never used an Api Call and don’t know how to manage it.

What should I Do :

  1. Get access to my Public Folder
  2. Find Sharable Link for images

My Question
How should be the script to “send the request”? (can’t figure out …) (need a full script)
How should be the “response” and how I should deserialize it (JsonUtily?)

Thank you a lot.

For now I only figured out that I should use WebRequest (but I don’t know how).
Already configured DropBox App and I have the Token.
From here and on I cannot understand what I should do…

I dont know how dropbox works, if they only upload changes to files or they upload the full file everytime (i imagine the first one) but you need a php script on your server (app?) to handle the upload of files, here is a small example of a zip upload (I have edited it because it is code from an old project with extra stuff you dont need so maybe I deleted something but is pretty much this)

        WWWForm formData = new WWWForm ();

        byte[] formBytes;

        formData.AddField("action", "zipupload");

        if (File.Exists("path/to/the/files/example.zip")) //HERE YOU FIND THE FILE TO UPLOAD
        {
            formBytes = File.ReadAllBytes("path/to/the/files/example.zip");
            formData.AddBinaryData("form", formBytes, "Form.zip");
        }

        string url = "http://URLtoYourSite/upload.php"; //CHANGE TO YOUR URL

        using (UnityWebRequest www = UnityWebRequest.Post (url, formData)) {

            string authorization = Authenticate (stUsername, stPassword); //only use this if you need user password
            byte[] boundary = UnityWebRequest.GenerateBoundary ();

            www.SetRequestHeader ("Authorization", authorization);

            yield return www.SendWebRequest ();

            if (www.isNetworkError || www.isHttpError) {
                Debug.LogError (www.error);
            } else {
                Debug.Log ("Files uploaded.");
                StringBuilder sb = new StringBuilder ();
                foreach (KeyValuePair<string, string> dict in www.GetResponseHeaders ()) {
                    sb.Append (dict.Key).Append (": 	[").Append (dict.Value).Append ("]

");
}

                Debug.Log ("Response headers: " + sb.ToString ());
                Debug.Log ("Response text: " + www.downloadHandler.text);
            }
        }

`then you need the php to move the files to your location in your server

AFTER ABOUT 20HR OF STUDY
I’ve managed to have a working Script…Really I fell like I was under torture :-). This script maybe is not “Super Clean” (I’ve a lot of missing info about true coding). It took the “API URL”, pass BODY PARAMETERS, pass Authorization Token. I was unable to use the WebRequest.Post because of Json Decode Warning. In the way below insted it work! Thank you for Help @xxmariofer. (Now I’m stucked in JsonDeSerialize but maybe i will use some dirty String Search, only need to find Shared_Link in Response)

public string Url = "https://api.dropboxapi.com/2/sharing/create_shared_link_with_settings";
		public string Token = "MySuperSecretToken";
		public string Path = "/Shared Folder";

// STRUCT DEI PARAMETRI DEL BODY
		public struct MyStruct
		{
			public string path;			
		}	
		// GENERO STRUCT
		public MyStruct DataFormBody;

IEnumerator Post_Easy()
			{
				// Assegno la Path
				DataFormBody.path = Path;
				// Converto in JSon
				string JSonBody = JsonUtility.ToJson(DataFormBody);
				// Passo il Parametro POST a UnityWebRequest
				var request = new UnityWebRequest(Url, "POST");
				// Codifico il Json in Byte Utf8
				byte[] bodyRaw = System.Text.Encoding.UTF8.GetBytes(JSonBody);
				// Assegno il Body in Parametro Upload
				request.uploadHandler = (UploadHandler) new UploadHandlerRaw(bodyRaw);
				// Assegno il Download del Response
				request.downloadHandler = (DownloadHandler) new DownloadHandlerBuffer();
				// Imposto l'Header di Autorizzazione
				request.SetRequestHeader ("Authorization", "Bearer " + Token);
				// Imposto la tipologia di comunicazione
				request.SetRequestHeader ("Content-Type", "application/json");
				// Invio la richiesta alla API DropBox
				yield return request.Send();
				
				// Verifica se ci sono errori di connesione
				 if (request.isNetworkError || request.isHttpError)
				 {
					 // Riporta l'errore di connesione
					 Debug.Log(request.error);
					 // Riporta ulteriori informazioni riguardo l'errore
					 string message = request.downloadHandler.text;
					 Debug.Log("response: " + message);					 
				 }
				 else
				 {
					// Scarica la risposta
					string message = request.downloadHandler.text;
					// Debug Status Code
					Debug.Log("Status Code: " + request.responseCode);
					// Debug Risposta
					Debug.Log("response: " + message);
					// Scrivo la risposta in un file
					File.WriteAllText("DropBox Response.txt",message);					
				 }				
			}
