HTTP Method Not Allowed in REST API Post

问题

I am using UnityWebRequest to POST a string on the JSON that is accessible online. Unfortunately I am getting HTTP/1.1 405 Method Not Allowed error in Unity. It is definitely not the API key error otherwise I would get unauthorized message.

I have seen some examples where PUT was used instead of POST, so I am not sure if what I am doing for POST here is right or not. Kindly help me out.

IEnumerator POSTURL()
    {
        WWWForm form = new WWWForm();
        form.AddField("ID", "Lemon");

        using (UnityWebRequest request = UnityWebRequest.Post("website_url", form))
        {
            request.SetRequestHeader("api-key", KEY);
            yield return request.SendWebRequest();

            if (request.isNetworkError || request.isHttpError)
            {
                Debug.Log(request.error);
            }
            else
            {
                Debug.Log("Form upload complete!");
            }
        }
    }

{
    "ID": "Orange",
    "Category": "Fruits",
}

Still just a guess but easier to explain what I mean here ^^

You probably have to use UnityWebRequest.Put

// You could pass these as parameters dynmically
IEnumerator POSTURL(string id, string category)
{
    // This is string interpolation and will dynamically fill in the 
    // id and category value
    var data = Encoding.UTF8.GetBytes($"{{\"ID\":\"{id}\",\"Category\":\"{category}\"}}");

    using (UnityWebRequest request = UnityWebRequest.Put("website_url", data))
    {
        request.SetRequestHeader("api-key", KEY);

        yield return request.SendWebRequest();

        if (request.isNetworkError || request.isHttpError)
        {
            Debug.Log(request.error);
        }
        else
        {
            Debug.Log("Form upload complete!");
        }
    }
}

Or as mentioned before you might also be able to follow this post and use Post but without a form but directly using raw data

var data = Encoding.UTF8.GetBytes($"{{\"ID\":\"{id}\",\"Category\":\"{category}\"}}");
UnityWebRequest webRequest = UnityWebRequest.Post(uri, "");

// Fix: Add upload handler and pass json as bytes array
webRequest.uploadHandler = new UploadHandlerRaw(data);

webRequest.SetRequestHeader("Content-Type", "application/json");
yield return webRequest.SendWebRequest();
