Question

我尝试将OAuth2不记名令牌和Post请求传递到我的服务器（使用Google Apps脚本执行API）。我尝试设置授权令牌的任何方式都会导致401未经授权的错误。我确定我以某种方式设置错误，但我一直无法弄清楚错误。

以下是我目前的代码。

private static UnityWebRequest createRequest(string functionName, List<string> parameters)
{
    PostData data = new PostData();
    data.Add("function", functionName);
    data.Add("parameters", string.Join(",", parameters.ToArray()));
    data.Add("devMode", "true"); // TODO: remove before launch

    Debug.Log(data.toJsonString());
    UnityWebRequest request = new UnityWebRequest(
            "https://script.googleapis.com/v1/scripts/" + SERVER_SCRIPT_ID + ":run",
            UnityWebRequest.kHttpVerbPOST);
    UploadHandlerRaw uploadHandler = new UploadHandlerRaw(data.toJsonBytes());
    request.uploadHandler = uploadHandler;
    request.downloadHandler = new DownloadHandlerBuffer();
    request.SetRequestHeader("Content-Type", "application/json; charset=utf-8");
    request.SetRequestHeader("Authorization", "Bearer " + DriveAPI.getInstance().getAuthToken());

    yield return request.Send();
    Debug.Log(request.downloadHandler.text);
}

[Serializable]
private class PostData : Dictionary<string, string>
{
    public byte[] toJsonBytes()
    {
        return Encoding.ASCII.GetBytes(toJsonString());
    }
    public string toJsonString()
    {
        string result = "{";
        foreach (string key in this.Keys)
        {
            string value;
            TryGetValue(key, out value);
            result += "\"" + key + "\":\"" + value + "\",";
        }
        result = result.Substring(0, result.Length - 1) + "}";
        return result;
    }
}

我尝试在实际的Data对象中设置标题，但也没有运气。

尝试enconding到UTF8，将UploadHandleRaw更改为UploadHandle并将请求设置为单个帖子：

private static UnityWebRequest createRequest(string functionName, List<string> parameters)
{
    PostData data = new PostData();
    data.Add("function", functionName);
    data.Add("parameters", string.Join(",", parameters.ToArray()));
    data.Add("devMode", "true"); // TODO: remove before launch

    Debug.Log(data.toJsonString());
    UnityWebRequest request = new UnityWebRequest("https://script.googleapis.com/v1/scripts/" + SERVER_SCRIPT_ID + ":run", "POST");
    UploadHandler uploadHandler =(UploadHandler) new UploadHandlerRaw(Encoding.UTF8.GetBytes(data.toJsonString()));
    request.uploadHandler = uploadHandler;
    request.downloadHandler = new DownloadHandlerBuffer();
    request.SetRequestHeader("Content-Type", "application/json");
    request.SetRequestHeader("Authorization", "Bearer " + DriveAPI.getInstance().getAuthToken());

    yield return request.Send();

    if (www.error != null)
    {
        Debug.Log("Error: " + www.error);
    }
    else
    {
        Debug.Log("Status Code: " + request.responseCode);
    }

}

原来我的代码工作正常。

来自Apps脚本的错误消息在发送Auth令牌时具有误导性。我能够通过从我的脚本（为Execution API端点提供服务）生成一个auth令牌并在我的应用程序中对该令牌进行硬编码来测试正确性。这样做会导致请求成功。

我已经检查过脚本和我的应用中使用的云项目是否相同，但仍然收到错误，但这是另一个问题的问题：）。
