I am trying to use the openai API in a new unity project. However try whatever I try I always get the same 400 bad request error
I have tried both options interleaving between simple JSOM and using wwwform but always the same error. The reason why I use classes is to be able to use the utility to transform to JSON because otherwise it can't be done.
I have a two versions of my code:
Version1
using UnityEngine;
using UnityEngine.Networking;
using System.Collections;
using System.Collections.Generic;
public class OpenAICommunication : MonoBehaviour
{
private string apiKey = "sk-....."; // hide apikey
private string apiUrl = "https://api.openai.com/v1/completions";
private void Update()
{
if(Input.GetButtonDown("Jump"))
AskQuestion("Hola! Este es un juego de unity!");
}
IEnumerator SendQuestion(string question)
{
MessagesList messages = new MessagesList();
messages.list = new Message[] { new Message() };
messages.list[0].role = "user";
messages.list[0].content = question;
ApiCall apiCall = new ApiCall();
apiCall.model = "text-davinci-003";
apiCall.prompt = question;
string json = JsonUtility.ToJson(apiCall);
Debug.Log("JSON: " + json);
// Configurar el encabezado de autorizaci�n
Dictionary<string, string> headers = new Dictionary<string, string>
{
{ "Content-Type", "application/json" },
{ "Authorization", "Bearer " + apiKey }
};
// headers.Add("Authorization", "Bearer " + apiKey);
// Enviar la solicitud POST a la API de OpenAI
using (UnityWebRequest www = UnityWebRequest.PostWwwForm(apiUrl, json))
{
foreach (var header in headers)
{
Debug.Log("HEADER: " + header.Key + header.Value);
www.SetRequestHeader(header.Key, header.Value);
}
yield return www.SendWebRequest();
if (www.result == UnityWebRequest.Result.ConnectionError || www.result == UnityWebRequest.Result.ProtocolError)
{
Debug.LogError("Error en la solicitud: " + www.error);
}
else
{
string responseJson = www.downloadHandler.text;
// Procesar la respuesta JSON aqu� (extraer y mostrar la respuesta del asistente)
Debug.Log("Response: " + responseJson);
}
}
}
public void AskQuestion(string question)
{
StartCoroutine(SendQuestion(question));
}
}
[System.Serializable]
public class Message
{
public string role;
public string content;
}
public class MessagesList
{
public Message[] list;
}
public class ApiCall
{
public string model;
public string prompt;
}
Version2
using UnityEngine;
using UnityEngine.Networking;
using System.Collections;
using System.Collections.Generic;
public class OpenAICommunication : MonoBehaviour
{
private string apiKey = "sk-...."; // hide apikey
private string apiUrl = "https://api.openai.com/v1/chat/completions";
private void Update()
{
if (Input.GetButtonDown("Jump"))
AskQuestion("Hola! Este es un juego de unity!");
}
IEnumerator SendQuestion(string question)
{
// Configurar el encabezado de autorizaci�n
Dictionary<string, string> headers = new Dictionary<string, string>
{
{ "Content-Type", "application/json" },
{ "Authorization", "Bearer " + apiKey }
};
// headers.Add("Authorization", "Bearer " + apiKey);
MessagesList messages = new MessagesList();
messages.list = new Message[] { new Message() };
messages.list[0].role = "user";
messages.list[0].content = question;
string json = JsonUtility.ToJson(messages);
// elimino la parte del string que no corresponde para formatear bien el json.
// lo eliminado es: { list: .... y el final }
json = json.Substring(8, json.Length - 8 - 1);
// verifico y es correcto.
Debug.Log("JSON: " + json);
// Preparar los datos para la solicitud POST utilizo la de chat también para probar pero no cambia nada...
WWWForm form = new WWWForm();
form.AddField("model", "gpt-3.5-turbo");
form.AddField("messages", json);
// Enviar la solicitud POST a la API de OpenAI
using (UnityWebRequest www = UnityWebRequest.Post(apiUrl, form))
{
foreach (var header in headers)
{
Debug.Log("HEADER: " + header.Key + header.Value);
www.SetRequestHeader(header.Key, header.Value);
}
yield return www.SendWebRequest();
if (www.result == UnityWebRequest.Result.ConnectionError || www.result == UnityWebRequest.Result.ProtocolError)
{
Debug.LogError("Error en la solicitud: " + www.error);
}
else
{
string responseJson = www.downloadHandler.text;
// Procesar la respuesta JSON aqu� (extraer y mostrar la respuesta del asistente)
Debug.Log("Response: " + responseJson);
}
}
}
public void AskQuestion(string question)
{
StartCoroutine(SendQuestion(question));
}
}
[System.Serializable]
public class Message
{
public string role;
public string content;
}
public class MessagesList
{
public Message[] list;
}
I use both variations of the code with two of the openai urls but always get the same error.

I tried the API in my terminal and it worked fine with the -k prefix.
I don't know why I have the 400 error in unity.
I ended up generating a server with NodeJS to see what I got from unity. Then I discovered that the POST was sending this information in data:
Received data: %7b%22model%22%3a%22gpt-3.5-turbo%22%2c%22messages%22%3a%5b%7b%22role%22%3a%22s ystem%22%2c%22content%22%3a%22Tu%20heres%20el%20master%20en%20un%20juego%20de%20roles%22%7d%2c %7b%22role%22%3a%22user%22%2c%22content%22%3a%22Hola%21%20Este%20es%20un%20juego%20de%20unity% 21%22%7d%5d%7d Erorr al formatear el json
Then I found a comment on the web that someone said that sometimes it was better to generate the byte string personally and not automatically, the answer was the following:
Received data: {"model":"gpt-3.5-turbo","messages":[{"role":"system","content":"Tu heres el ma ster en un juego de roles"},{"role":"user","content":"Hola! Este es un juego de unity!"}]}
This is the code that finally worked for any of the options in the original post.
using (UnityWebRequest www = UnityWebRequest.PostWwwForm(apiUrl, json))
{
www.method = "POST"; //alternative
//funtional code
byte[] jsonToSend = new System.Text.UTF8Encoding().GetBytes(json);
www.uploadHandler = (UploadHandler)new UploadHandlerRaw(jsonToSend);
www.downloadHandler = (DownloadHandler)new DownloadHandlerBuffer();
//end funtional code
foreach (var header in headers)
{
www.SetRequestHeader(header.Key, header.Value);
}
yield return www.SendWebRequest();
if (www.result == UnityWebRequest.Result.ConnectionError || www.result == UnityWebRequest.Result.ProtocolError)
{
Debug.LogError("Error en la solicitud: " + www.error);
}
else
{
string responseJson = www.downloadHandler.text;
// Procesar la respuesta JSON aqu� (extraer y mostrar la respuesta del asistente)
Debug.Log("Response: " + responseJson);
}
}
