通过C＃中的imageshack API发布图片 [英] Posting image via imageshack API in C#

问题描述

你好！我几天都在苦苦挣扎，所以任何帮助都会很明显

所以。以下是文档参考 [ ^ ]

我尝试过这样的方法

  public   static   void  UploadImage（HttpPostedFileBase image）
 {
  var  httpWReq = 
（HttpWebRequest）WebRequest.Create（  http://www.imageshack.us/upload_api.php）; 
 
 httpWReq.Method =   POST; 
 httpWReq.ContentType =   multipart / form-data; 
 httpWReq.KeepAlive =  true ; 
 
  var  stream = httpWReq.GetRequestStream（）; 
  var  encoding =  new  UTF8Encoding（）; 
  var  postData =   key = / *我的钥匙* /; 
 postData + =  & fileupload =; 
  byte  [] data = encoding.GetBytes（postData）; 
 stream.Write（data， 0 ，data.Length）; 
  var  buffer =  new   byte  [ 4096 ]; 
  int  bytesread; 
  while （（bytesread = image.InputStream.Read（buffer， 0 ，buffer.Length ））！=  0 ）
 {
 stream.Write（buffer， 0  ，bytesread）; 
} 
 stream.Close（）; 
 
 
  var  response =（HttpWebResponse）httpWReq.GetResponse（）; 
 
  string  responseString =  new  StreamReader（response.GetResponseStream（））。ReadToEnd （）; 
} 

但它给出了错误你必须提供有效的密钥。问题是密钥100％有效。当我改为

 httpWReq.ContentType =   application / x-www-form-urlencoded; 

密钥不再出错，但有错误没有上传文件或空文件。

这里是一些示例代码，我如何使用这种方法

 [HttpPost] 
  public  ActionResult SomeAction（SomeViewModel model）
 {
  //   I拍摄用户上传的图像并将其存储到imageshack  
 UploadeImage（model.Image）; 
 RedirectToAction（  Index）; 
} 

所以问题是：此代码中是否有任何错误，或者是否有通过此API发布图像的下降方法？

提前致谢！

Hi guys! I'm seriously struggling several days, so any help would be appreciable
So. Here is reference for documentation[^]
I've tried such approach

public static void UploadImage(HttpPostedFileBase image)
        {
            var httpWReq =
                (HttpWebRequest)WebRequest.Create("http://www.imageshack.us/upload_api.php");

            httpWReq.Method = "POST";
            httpWReq.ContentType = "multipart/form-data";
            httpWReq.KeepAlive = true;

            var stream = httpWReq.GetRequestStream();
            var encoding = new UTF8Encoding();
            var postData = "key=/*my key*/";
            postData += "&fileupload=";
            byte[] data = encoding.GetBytes(postData);
            stream.Write(data, 0, data.Length);
            var buffer = new byte[4096];
            int bytesread;
            while ((bytesread = image.InputStream.Read(buffer, 0, buffer.Length)) != 0)
            {
                stream.Write(buffer, 0, bytesread);
            }
            stream.Close();


            var response = (HttpWebResponse)httpWReq.GetResponse();

            string responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
}

but it gives me error "you must provide valid secret key". The problem is that key is 100% valid. And when I change to

httpWReq.ContentType = "application/x-www-form-urlencoded";

there is no longer error with key, but there is error "no file or empty file was uploaded".
Here's some sample code, how I use this method

[HttpPost] 
public ActionResult SomeAction (SomeViewModel model)
{
    //I take image uploaded by user and store it into imageshack
    UploadeImage(model.Image);
    RedirectToAction("Index");
}

So the question is: Are there any mistakes in this code or is there any more descent approach to post image via this API?
Thanks in advance!
