Question

因此，我正在使用Dailymotion API上传视频，并使用从GitHub获得的代码，它可以正常工作，但在播放4个视频后会出现例外：

{“远程服务器返回错误：（403）禁止。”}

我在PublishVideo方法中遇到错误

var response = request.GetResponse（）;

主要代码

        var accessToken = GetAccessToken();
        Authorize(accessToken);

        Console.WriteLine("Access token is " + accessToken);

        var fileToUpload = @"E:\Courses\[FreeCourseSite.com] Udemy - Entity Framework in Depth The Complete Guide\3. Building a Model using Database-First Workflow\11. Summary.mp4";

        Console.WriteLine("File to upload is " + fileToUpload);

        var uploadUrl = GetFileUploadUrl(accessToken);

        Console.WriteLine("Posting to " + uploadUrl);

        var response = GetFileUploadResponse(fileToUpload, accessToken, uploadUrl);

        Console.WriteLine("Response:\n");

        Console.WriteLine(response + "\n");

        Console.WriteLine("Publishing video.\n");
        var uploadedResponse = PublishVideo(response, accessToken);

        Console.WriteLine(uploadedResponse);

        Console.WriteLine("Done. Press enter to exit.");
        Console.ReadLine();
    }

    {
        var client = new WebClient();
        client.Headers.Add("Authorization", "OAuth " + accessToken);

        var responseBytes = client.UploadFile(uploadUrl, fileToUpload);

        var responseString = Encoding.UTF8.GetString(responseBytes);

        var response = JsonConvert.DeserializeObject<UploadResponse>(responseString);

        return response;
    }

    private static UploadedResponse PublishVideo(UploadResponse uploadResponse, string accessToken)

这可能与许多原因有关。我建议您捕获错误并从我们的API获取响应流：

    try{
            var response = request.GetResponse();
            var responseStream = response.GetResponseStream();
            string responseString;
            using (var reader = new StreamReader(responseStream))
            {
                responseString = reader.ReadToEnd();
            }

            var uploadedResponse = JsonConvert.DeserializeObject<UploadedResponse>(responseString);
            return uploadedResponse;
        }
        catch(WebException e){

            var rs = e.Response.GetResponseStream();
            string errorResponseString;
            using (var reader = new StreamReader(rs))
            {
                errorResponseString = reader.ReadToEnd();
            }

            Console.WriteLine(errorResponseString);  
            return null;  
        }

您将收到一条消息，向您解释为什么禁止您的访问。我还邀请您检查我们的API速率限制规则，这可能是禁止调用的原因：https://developer.dailymotion.com/api/#rate-limit
