问题描述

Imgur 是一个图片上传网站谁提供的 API上传

我的代码看起来完全一样，他们提供作为PHP代码例。然而，在他们的PHP代码，他们是 http_build_query（$ pvars）;

好像他们是URL编码的查询之前张贴。编辑：请注意，我已经改变了充分.NET 3.5而不是客户端配置文件。这给了我进入的System.Web 所以我用 httputliity.urlencode（）。这使得API返回一个失败与无图像派。如果我不那么编码API返回一个好的链接到图片，但没有图片上传（像一个空白文件）。

如何解决我的代码来对他们的API正常工作？

 形象画像= Image.FromFile（C：\\Users\\Affan\\Pictures\\1509310.jpg）; 
的MemoryStream毫秒​​=新的MemoryStream（）; 
 //图像转换为byte [] 
 image.Save（MS，System.Drawing.Imaging.ImageFormat.Jpeg）; 
字节[] = imageBytes ms.ToArray（）; 
 
的WebRequest WB = WebRequest.Create（新的URI（http://imgur.com/api/upload.xml））; 
 wb.ContentType =应用/的X WWW的形式，进行了urlencoded 
 wb.Method =POST; 
 wb.Timeout = 10000; 
 Console.WriteLine（imageBytes.Length）; 
字符串参数=键= 433a1bf4743dd8d7845629b95b5ca1b4&安培;图像=+ Convert.ToBase64String（imageBytes）; 
 
 
 Console.WriteLine（参​​数：+ parameters.Length）; 
 System.Text.UTF8Encoding编码=新System.Text.UTF8Encoding（）; 
字节[]字节= encoding.GetBytes（参数）; 
 //字节[]字节= Convert.FromBase64String（参数）; 
 
的System.IO.Stream OS = NULL; 
试{//发送邮报
 wb.ContentLength = bytes.Length; //数字节发送
 OS = wb.GetRequestStream（）; 
 os.Write（字节，0，bytes.Length）; //发送它
}赶上（引发WebException前）{
 MessageBox.Show（ex.Message，HttpPost：请求错误）; 
 Console.WriteLine（ex.Message）; 
} {最后
如果（OS！= NULL）{
 // os.Close（）; 
} 
} 
 
试{//得到响应
 WebResponse类WebResponse类= wb.GetResponse（）; 
 
 StreamReader的SR =新的StreamReader（webResponse.GetResponseStream（））; 
 //MessageBox.Show(sr.ReadToEnd（）修剪（））; 
 Console.WriteLine（sr.ReadToEnd（）修剪（））; 
}赶上（引发WebException前）{
 MessageBox.Show（ex.Message，HttpPost：响应错误）; 
} 
  

解决方案

我刚刚上传了该图片

使用此代码：

 使用（VAR W =新的WebClient（））
 { 
 VAR值=新的NameValueCollection 
 {
 {键，433a1bf4743dd8d7845629b95b5ca1b4}，
 {形象，Convert.ToBase64String（File.ReadAllBytes（@hello.png ））} 
}; 
 
字节[] =响应w.UploadValues​​（http://imgur.com/api/upload.xml，值）; 
 
 Console.WriteLine（XDocument.Load（新的MemoryStream（响应）））; 
} 
  

您可能会想现在就改变你的API密钥： - ）

输出是：

 <可吸入悬浮粒子STAT =OK> 
< image_hash> IWg2O< / image_hash> 
< delete_hash> fQAXiR2Fdq< / delete_hash> 
< original_image> HTTP：//i.imgur.com/IWg2O.png< / original_image> 
< large_thumbnail> HTTP：//i.imgur.com/IWg2Ol.jpg< / large_thumbnail> 
< small_thumbnail> HTTP：//i.imgur.com/IWg2Os.jpg< / small_thumbnail>

Imgur is a image uploading website who offers an API to upload

My code looks exactly like the PHP code they provide as an example. however, in their php code they are http_build_query($pvars);

It seems like they are URLEncoding their query before posting it. edit: Note that I have changed to full .NET 3.5 rather then the client profile. This gave me access to system.web so I used httputliity.urlencode(). This made the api return a "fail" with a "no image was sent". If I don't encode then the API returns an "okay" with a link to the picture, however no picture is uploaded (like a blank file).

How can I fix my code to work properly against their API?

 Image image = Image.FromFile("C:\\Users\\Affan\\Pictures\\1509310.jpg");
        MemoryStream ms = new MemoryStream();
        // Convert Image to byte[]
        image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
        byte[] imageBytes = ms.ToArray();

        WebRequest wb = WebRequest.Create(new Uri("http://imgur.com/api/upload.xml"));
        wb.ContentType = "application/x-www-form-urlencoded";            
        wb.Method = "POST";
        wb.Timeout = 10000;
        Console.WriteLine(imageBytes.Length);
        string parameters = "key=433a1bf4743dd8d7845629b95b5ca1b4&image=" + Convert.ToBase64String(imageBytes);


        Console.WriteLine("parameters: " + parameters.Length);
        System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
        byte[] bytes = encoding.GetBytes(parameters);
        // byte[] bytes = Convert.FromBase64String(parameters);

        System.IO.Stream os = null;
        try { // send the Post
            wb.ContentLength = bytes.Length;   //Count bytes to send
            os = wb.GetRequestStream();               
            os.Write(bytes, 0, bytes.Length);         //Send it
        } catch (WebException ex) {
            MessageBox.Show(ex.Message, "HttpPost: Request error");
            Console.WriteLine(ex.Message);
        } finally {
            if (os != null) {
               // os.Close();
            }
        }

        try { // get the response
            WebResponse webResponse = wb.GetResponse();

            StreamReader sr = new StreamReader(webResponse.GetResponseStream());
            //MessageBox.Show(sr.ReadToEnd().Trim());
            Console.WriteLine(sr.ReadToEnd().Trim());
        } catch (WebException ex) {
            MessageBox.Show(ex.Message, "HttpPost: Response error");
        }       

解决方案

I've just uploaded this image

using this code:

using (var w = new WebClient())
{
    var values = new NameValueCollection
    {
        { "key", "433a1bf4743dd8d7845629b95b5ca1b4" },
        { "image", Convert.ToBase64String(File.ReadAllBytes(@"hello.png")) }
    };

    byte[] response = w.UploadValues("http://imgur.com/api/upload.xml", values);

    Console.WriteLine(XDocument.Load(new MemoryStream(response)));
}

You might want to change your API key now :-)

The output was:

<rsp stat="ok">
  <image_hash>IWg2O</image_hash>
  <delete_hash>fQAXiR2Fdq</delete_hash>
  <original_image>http://i.imgur.com/IWg2O.png</original_image>
  <large_thumbnail>http://i.imgur.com/IWg2Ol.jpg</large_thumbnail>
  <small_thumbnail>http://i.imgur.com/IWg2Os.jpg</small_thumbnail>
  <imgur_page>http://imgur.com/IWg2O</imgur_page>
  <delete_page>http://imgur.com/delete/fQAXiR2Fdq</delete_page>
</rsp>
