Hi,
I have a question about upload big size file on imgur.
I found a source code for uploading images on imgur.com using api
It works for small size image file but it doesn't work for big size image file
I have tested with 488kb size image file.
The error returns 400 bad request server error.
Here is my source code and please give me an advice
Thank you

private string upload_img(string img_name)
       {
           string img_url = "";
           try
           {
               string api_url_image = "https://api.imgur.com/3/image";
             //  string api_url = "https://api.imgur.com/3/upload";

               HttpWebRequest request = (HttpWebRequest)WebRequest.Create(api_url_image);
               request.Headers.Add("Authorization", "Client-ID <<My client ID Here>>");    //authorized id
          

               request.Method = "POST";
Folder name\\" + img_name;

               FileStream file = new FileStream(filePath, FileMode.Open);
               byte[] image = new byte[file.Length];
               file.Read(image, 0, (int)file.Length);
               ASCIIEncoding enc = new ASCIIEncoding();
               string postData = Convert.ToBase64String(image);
               byte[] bytes = enc.GetBytes(postData);

               request.ContentType = "application/x-www-form-urlencoded";
               request.ContentLength = bytes.Length;

               Stream writer = request.GetRequestStream();
               writer.Write(bytes, 0, bytes.Length);

               HttpWebResponse response = (HttpWebResponse)request.GetResponse();
               response.GetResponseStream();

               if (response.StatusCode == HttpStatusCode.OK)
               {

                   Stream responseStream = response.GetResponseStream();
                   string responseStr = new StreamReader(responseStream).ReadToEnd();

                   img_url = responseStr.Remove(0, responseStr.IndexOf("link") + 7);
                   img_url = img_url.Substring(0, img_url.IndexOf("success") - 4);
                   img_url = img_url.Replace("\\","");
                   responseStream.Close();
               }
               response.Close();
           }
           catch (Exception ex)
           {
               MessageBox.Show(ex.Message);
           }
         
           return img_url;
       }

我的尝试：



我已将api密钥从匿名密钥更改为授权密钥，但它返回相同的错误

What I have tried:

I have changed the api key to authorized key from anonymous key but it returns same error

推荐答案

问题是我限制了我下载时的文件大小

The problem was I limited the file size when I download it

您正在尝试上传表单数据，但使用的是URL编码。检查您的内容类型。

You're trying to upload form data, but using URL encoding. Check your content type.
