为什么Post请求OpenAI在统一导致错误400?

Question

我试图在我正在制作的游戏中使用GPT3，但我似乎无法正确调用OpenAI API。我从Unity文档中获得了大部分内容。下面是我使用的代码:

public class gpt3_complete : MonoBehaviour
{
public string model;
public string prompt;
public int len;
public string temp;
public string api_key = "<key>";
void Start()
{
StartCoroutine(Upload());
}
IEnumerator Upload()
{
WWWForm form = new WWWForm();
form.AddField("model", model);
form.AddField("prompt", prompt);
form.AddField("max_tokens", len);
form.AddField("temperature", temp);
//form.headers.Add("Authorization", "Bearer "+api_key);

using (UnityWebRequest www = UnityWebRequest.Post("https://api.openai.com/v1/completions", form))
{
www.SetRequestHeader("Authorization", "Bearer " + api_key);
www.SetRequestHeader("Content-Type", "application/json");
yield return www.SendWebRequest();
if (www.result != UnityWebRequest.Result.Success)
{
Debug.Log(www.error);
}
else
{
Debug.Log(www.result);
Debug.Log("Form upload complete!");
}
}
}
}

这总是返回:400错误请求。GPT3文档可以在这里找到:https://beta.openai.com/docs/api-reference/completions/create

知道这是为什么吗?这是我第一次用unity制作网页请求，所以我可能遗漏了一些明显的东西。谢谢!

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Networking;
using System.Text;
public class OpenAIRequest : MonoBehaviour
{
public string apiKey = "YOUR_API_KEY_HERE";
public string prompt = "Once upon a time, in a land far far away, there lived a brave knight";
public string model = "text-davinci-002";
public int maxTokens = 100;
void Start()
{
StartCoroutine(GetOpenAIResponse());
}
IEnumerator GetOpenAIResponse()
{
string url = "https://api.openai.com/v1/engines/" + model + "/completions";
string requestData = "{"prompt": "" + prompt + "", "max_tokens": " + maxTokens + "}";
UnityWebRequest request = new UnityWebRequest(url, "POST");
byte[] bodyRaw = Encoding.UTF8.GetBytes(requestData);
request.uploadHandler = (UploadHandler)new UploadHandlerRaw(bodyRaw);
request.downloadHandler = (DownloadHandler)new DownloadHandlerBuffer();
request.SetRequestHeader("Content-Type", "application/json");
request.SetRequestHeader("Authorization", "Bearer " + apiKey);
yield return request.SendWebRequest();
if (request.result != UnityWebRequest.Result.Success)
{
Debug.Log(request.error);
}
else
{
string response = request.downloadHandler.text;
Debug.Log(response);
}
}
}

结果
