Question

尝试将图片上传到eBay，以获取AddFixedPriceItem调用中的产品变体。

我已将代码复制到我的程序表单中：https://ebay.custhelp.com/app/answers/detail/a_id/1093/~/.net-sample-in-c%23-for-uploadsitehostedpictures

在调试过程中，我仔细检查了令牌，密钥和eBay（沙盒）URL是否全部用于沙箱并正确加载到变量中。我不确定我还需要做什么？

代码在遇到resp = (HttpWebResponse)req.GetResponse();

时会抛出异常

WebException：“远程服务器返回错误：（500）内部服务器错误”

这是我的代码（没有密钥）：

静态字符串UploadSiteHostedPicture（string imageUrl） { string response = string.Empty;

    string token = ConfigurationManager.AppSettings["UserAccount.ApiToken"];
    string SandboxOrProductionURL = ConfigurationManager.AppSettings["Environment.ApiServerUrl"];
    string PictureURL = imageUrl;
    string DevID = "Keys were removed before posting on stackoverflow";
    string AppID = "Keys were removed before posting on stackoverflow";
    string CertID = "Keys were removed before posting on stackoverflow";
    string payload = "<?xml version=\"1.0\" encoding=\"utf-8\"?> " +
    "<UploadSiteHostedPicturesRequest xmlns=\"urn:ebay:apis:eBLBaseComponents\">" +
    "<ExternalPictureURL>" + PictureURL + "</ExternalPictureURL>" +
    "<RequesterCredentials><eBayAuthToken>" + token + "</eBayAuthToken></RequesterCredentials>" +
    "</UploadSiteHostedPicturesRequest>";
    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(SandboxOrProductionURL);
    HttpWebResponse resp = null;
    //Add the request headers
    req.Headers.Add("X-EBAY-API-COMPATIBILITY-LEVEL", "803");
    req.Headers.Add("X-EBAY-API-SITEID", "0");
    req.Headers.Add("X-EBAY-API-CALL-NAME", "UploadSiteHostedPictures");
    req.Headers.Add("X-EBAY-API-DEV-NAME", DevID);
    req.Headers.Add("X-EBAY-API-APP-NAME", AppID);
    req.Headers.Add("X-EBAY-API-CERT-NAME", CertID);
    //set the method to POST
    req.Method = "POST";
    //Convert the string to a byte array
    byte[] postDataBytes = System.Text.Encoding.ASCII.GetBytes(payload);
    int len = postDataBytes.Length;
    req.ContentLength = len;
    //Post the request to eBay
    System.IO.Stream requestStream = req.GetRequestStream();
    requestStream.Write(postDataBytes, 0, len);
    requestStream.Close();
    try
    {
        // get response and write to console
        resp = (HttpWebResponse)req.GetResponse(); //THIS IS WHERE THE EXCEPTION OCCURS
        StreamReader responseReader = new StreamReader(resp.GetResponseStream(), Encoding.UTF8);
        string output = responseReader.ReadToEnd();
        resp.Close();
        XmlDocument xmlResponse = new XmlDocument();
        xmlResponse.LoadXml(output);
        response = xmlResponse.ToString();
        //process response
        //show them how to get the full url and specify that in the AddItem request
    }
    catch (Exception ex)
    {
        MessageBox.Show("Exception caught from UploadSiteHostedPictures method:\r\n\r\n" + ex.Message);
    }
    return response;
}

我使用的是错误的沙盒网址。通常我使用SOAP，但我没有意识到它们对于XML调用是不同的。见这里：https://developer.ebay.com/DevZone/support/knowledgebase/

此外，上面的代码是错误的，因为它没有从XML响应中正确提取上传的图像URL（并且不返回它）。如果你想看到我的noob解决方案，那么这就是应该在try块中的代码（上图）：

  try
        {
            // get response and write to console
            resp = (HttpWebResponse)req.GetResponse();
            StreamReader responseReader = new StreamReader(resp.GetResponseStream(), Encoding.UTF8);
            string output = responseReader.ReadToEnd();
            resp.Close();
            //XmlDocument xmlResponse = new XmlDocument();
            //xmlResponse.LoadXml(output);

            string[] outputArray1 = Regex.Split(output, @"<FullURL>");
            string urlNowAtFrontOfString = outputArray1[1];
            string[] outputArray2 = Regex.Split(urlNowAtFrontOfString, @"</FullURL>");
            response = outputArray2[0];
            //process response
            //show them how to get the full url and specify that in the AddItem request
        }

编译时UploadSiteHostedPictures异常错误500：resp =（HttpWebResponse）req.GetResponse（）;
