how do I upload a image to cloudinary via Unity c#. 502 Bad Gateway

Ferrrari177

this is a test upload to get it working. The cloudName ,apikey, apiSecret are fake.

Error Code 502 Bad Gateway on calling UploadImage();

using System.Collections;

using UnityEngine;

using UnityEngine.Networking;

public class ImageUploader : MonoBehaviour

{

  public string cloudName = "ddfthjydfn"; // 

  public string apiKey = "34546345345353";

  public string apiSecret = "acQakere7d6gdfdfgFLJQPU_Te4y7QY";

  public string uploadPreset = "default"; // The upload preset defined in your Cloudinary account

  public string imagePath; // The local path of the image you want to upload

  public void UploadImage(Texture2D Textureimage)

  {

    StartCoroutine(UploadImageCoroutine(ConvertTextureToByteArray(Textureimage)));

  }

  private IEnumerator UploadImageCoroutine(byte[] imageBytes)

  {

    // Read the image file bytes

    //byte[] imageBytes = System.IO.File.ReadAllBytes(imagePath);

    // Construct the URL for the upload API endpoint

        string uploadUrl = $"https://api.cloudinary.com/v1_1/{cloudName}/image/upload";

    // Create a new UnityWebRequest instance

    UnityWebRequest request = new UnityWebRequest(uploadUrl, UnityWebRequest.kHttpVerbPOST);

    // Set the request method and headers

    request.method = UnityWebRequest.kHttpVerbPOST;

    request.SetRequestHeader("Content-Type", "multipart/form-data");

    // Set the form data parameters

    WWWForm form = new WWWForm();

    form.AddBinaryData("file", imageBytes, "image.png", "image/png");

    form.AddField("upload_preset", uploadPreset);

    form.AddField("api_key", apiKey);

    // Attach the form data to the request

    request.uploadHandler = new UploadHandlerRaw(form.data);

    request.downloadHandler = new DownloadHandlerBuffer();

    // Send the request

    yield return request.SendWebRequest();

    // Check for errors

    if (request.result == UnityWebRequest.Result.Success)

    {

      Debug.Log("Image uploaded successfully!");

    }

    else

    {

      Debug.LogError($"Error uploading image: {request.error}");

    }

  }

  public byte[] ConvertTextureToByteArray(Texture2D texture)

  {

    // Encode the texture to PNG format

    byte[] byteArray = texture.EncodeToPNG();

    return byteArray;

  }

}

Hi @Ferrrari177,

In order to investigate, could you share your cloud_name?

Thanks in advance.

Best,

Hi @Ferrrari177,

I believe the 502 is coming from Unity.

In our logs, I can see 1 upload on our side that is failing with an error 400 because you are setting the upload_preset to default which doesn't exist in your account.

Can you try to set it to test_cld and see if that works? It is a preset I just created.

Thanks,

Loic

Hi Loic,

I changed the uploadPreset = "test_cld", but still have a 502 error.

Thanks

Hi Loic,

The apiSecret is no used on the upload, should this be?

Hi Lee,

Thank you for the update. Unsigned Upload is a mechanism in the Upload process which is controlled via upload preset. Please check the aforementioned link for detailed documentation.

Thank you Anthony,

I can see that the test_cld has been made for me by Loic and is unsigned. This still had the 502 error.

I will spend a few days adjusting setting on the setting page and see If I can get it to upload.

I will look though the documentation and try to work it out myself.

Thanks

Hi Lee,

Thank you for the update. Please do not hesitate to reach out again if have any questions. I have similar integration but in Blender, in which I use the same unsigned upload mechanism to directly upload the 3D model to Cloudinary. Here's my repo: https://github.com/tdatu/cloudinary_exporter

I hope that helps.
