如何构建此帖子？

我一直在使用提示from this guide (the FormUpload answer)。我发布的数据是这样的：

就个人而言，我认为问题出在以下字段中，我不知道如何复制。在上面的代码中，我在字典中添加了string.empty。

这是适用于浏览器版本的字段：

------WebKitFormBoundaryTbZqL4CZcQwC7K58
Content-Disposition: form-data; name="ctl00$ctl00$ctl00$ctl00$cphContent$cphMain$cphMain$userInfo$MultiUpload$fuFallbackGalleryImageUpload"; filename=""
Content-Type: application/octet-stream

如果有人有兴趣，我会使用以下代码发布帖子：

 public static class FormUpload
    {
        private static readonly Encoding encoding = Encoding.UTF8;
        public static HttpWebResponse MultipartFormDataPost(string postUrl, string userAgent, Dictionary<string, string> postParameters, CookieContainer container)
        {
            string formDataBoundary = String.Format("----------{0:N}", Guid.NewGuid());
            string contentType = "multipart/form-data; boundary=" + formDataBoundary;

            byte[] formData = GetMultipartFormData(postParameters, formDataBoundary);

            return PostForm(postUrl, userAgent, contentType, formData, container);
        }
        private static HttpWebResponse PostForm(string postUrl, string userAgent, string contentType, byte[] formData, CookieContainer container)
        {
            HttpWebRequest request = WebRequest.Create(postUrl) as HttpWebRequest;

            if (request == null)
            {
                throw new NullReferenceException("request is not a http request");
            }

            // Set up the request properties.
            request.Method = "POST";
            request.ContentType = contentType;
            request.UserAgent = userAgent;
            request.CookieContainer = container;
            request.UserAgent =

            request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
            request.Headers.Add("Accept-Encoding", "gzip,deflate,sdch");
            request.Headers.Add("Accept-Language", "en-US,en;q=0.8,da;q=0.6");

            request.Headers.Add("Cache-Control", "max-age=0");
            request.ContentLength = formData.Length;

            // You could add authentication here as well if needed:
            // request.PreAuthenticate = true;
            // request.AuthenticationLevel = System.Net.Security.AuthenticationLevel.MutualAuthRequested;
            // request.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(System.Text.Encoding.Default.GetBytes("username" + ":" + "password")));

            // Send the form data to the request.
            using (Stream requestStream = request.GetRequestStream())
            {
                requestStream.Write(formData, 0, formData.Length);
                requestStream.Close();
            }

            return request.GetResponse() as HttpWebResponse;
        }

        private static byte[] GetMultipartFormData(Dictionary<string, string> postParameters, string boundary)
        {
            Stream formDataStream = new System.IO.MemoryStream();
            bool needsCLRF = false;

            foreach (var param in postParameters)
            {
                // Thanks to feedback from commenters, add a CRLF to allow multiple parameters to be added.
                // Skip it on the first parameter, add it to subsequent parameters.
                if (needsCLRF)
                    formDataStream.Write(encoding.GetBytes("\r\n"), 0, encoding.GetByteCount("\r\n"));

                needsCLRF = true;

                    string postData = string.Format("--{0}\r\nContent-Disposition: form-data; name=\"{1}\"\r\n\r\n{2}",
                        boundary,
                        param.Key,
                        param.Value);
                    formDataStream.Write(encoding.GetBytes(postData), 0, encoding.GetByteCount(postData));

            }

            // Add the end of the request.  Start with a newline
            string footer = "\r\n--" + boundary + "--\r\n";
            formDataStream.Write(encoding.GetBytes(footer), 0, encoding.GetByteCount(footer));

            // Dump the Stream into a byte[]
            formDataStream.Position = 0;
            byte[] formData = new byte[formDataStream.Length];
            formDataStream.Read(formData, 0, formData.Length);
            formDataStream.Close();

            return formData;
        }

        public class FileParameter
        {
            public byte[] File { get; set; }
            public string FileName { get; set; }
            public string ContentType { get; set; }
            public FileParameter(byte[] file) : this(file, null) { }
            public FileParameter(byte[] file, string filename) : this(file, filename, null) { }
            public FileParameter(byte[] file, string filename, string contenttype)
            {
                File = file;
                FileName = filename;
                ContentType = contenttype;
            }
        }
    }

好的，很多代码和文字。任何有使用multipart / form-data制作HTTP帖子经验的人都可能会给出一些提示。 “302发现”可能是一个提示，我不知道。

非常感谢任何可以指向我方向的帮助！

答案 0 :(得分：3)

首先，正如您可能看到的那样，您正在复制参数信息。

原帖：

------WebKitFormBoundaryTbZqL4CZcQwC7K58
Content-Disposition: form-data; name="__EVENTTARGET"

你的帖子：

------------63f74b64334e4c8fad891bd1f969402b
Content-Disposition: form-data; name="Content-Disposition: form-data; name="__EVENTTARGET""

使用您正在使用的代码，您只需使用字典中的参数名称，因为代码已添加Content-Disposition: form-data; name=：

string postData = string.Format("--{0}\r\nContent-Disposition: form-data; name=\"{1}\"\r\n\r\n{2}",
                    boundary,            //^^^Right Here!^^^^
                    param.Key,
                    param.Value);

我的建议是保留FormUpload代码，只需更改构建字典的方式。

//Change this...
namValCollection.Add("Content-Disposition: form-data; name=\"__EVENTTARGET\"", "ctl00$ctl00$ctl00$ctl00$cphContent$cphMain$cphMain$userInfo$btnSend");
namValCollection.Add("Content-Disposition: form-data; name=\"__EVENTARGUMENT\"", string.Empty);
....

//...into this:
namValCollection.Add("__EVENTTARGET", "ctl00$ctl00$ctl00$ctl00$cphContent$cphMain$cphMain$userInfo$btnSend");
namValCollection.Add("__EVENTARGUMENT", string.Empty);
....


++++++++++++++++++++++++++++++++++++++
继续下一个问题，你有点删除了处理文件上传的FormUpload代码中的一个非常重要的部分。在原始POST中，即使您实际上没有上传文件，也会发送一个文件参数。您可以像使用the question you linked一样使用FormUpload.FileParameter类，只需进行一些小调整：

namValCollection.Add("ctl00$ctl00$ctl00$ctl00$cphContent$cphMain$cphMain$userInfo$MultiUpload$fuFallbackGalleryImageUpload", new FormUpload.FileParameter(new byte[0]));
//Just use 'new FormUpload.FileParameter(new byte[0])' in place of actual file information if your not uploading a file.

将其添加回FormUpload代码，但请务必更改一行：

if (param.Value is FileParameter)
{
    FileParameter fileToUpload = (FileParameter)param.Value;

    string header = string.Format("--{0}\r\nContent-Disposition: form-data; name=\"{1}\"; filename=\"{2}\";\r\nContent-Type: {3}\r\n\r\n",
                    boundary,
                    param.Key,
                    fileToUpload.FileName ?? String.Empty, //Change this line from 'fileToUpload.FileName ?? param.Key.' to 'fileToUpload.FileName ?? String.Empty,'
                    fileToUpload.ContentType ?? "application/octet-stream");

    formDataStream.Write(encoding.GetBytes(header), 0, encoding.GetByteCount(header));

    formDataStream.Write(fileToUpload.File, 0, fileToUpload.File.Length);
}
else
{
    string postData = string.Format("--{0}\r\nContent-Disposition: form-data; name=\"{1}\"\r\n\r\n{2}",
                    boundary,
                    param.Key,
                    param.Value);
    formDataStream.Write(encoding.GetBytes(postData), 0, encoding.GetByteCount(postData));
}
