我已经搜索了如何使用控制台应用程序将文件上传到网站,并且我已经达到某种方式,看起来是正确的方式,但我没有成功。所以我需要一些帮助!
首先,我建立的解决方案如下:
class Program
{
static void Main(string[] args)
{
//Program.Test1();
Program.Test3();
Console.ReadLine();
}
public static void Test3()
{
//Set this to dont get an Invalid Request Exception
System.Net.ServicePointManager.Expect100Continue = false;
//Set a real page for this test
string url = "http://www.toledorocket.com/perftest/uploadtest/fileselect.asp";
string[] files = { "C:\\Documents and Settings\\wkurten\\Desktop\\fogao.txt" }; //Put some real file
NameValueCollection nvc = new NameValueCollection();
nvc.Add("FILE1", "fogao.txt");
string boundary = "----------------------------" +
DateTime.Now.Ticks.ToString("x");
HttpWebRequest httpWebRequest2 = (HttpWebRequest)WebRequest.Create(url);
httpWebRequest2.ContentType = "multipart/form-data; boundary=" +
boundary;
httpWebRequest2.Method = "POST";
httpWebRequest2.KeepAlive = true;
httpWebRequest2.Credentials =
System.Net.CredentialCache.DefaultCredentials;
//Is you have an connection with proxy, uncomment and set the values bellow:
/*NetworkCredential localNetworkCredential = new NetworkCredential("user", "pass", "domain");
httpWebRequest2.Proxy = new WebProxy("server:port", false);
httpWebRequest2.Proxy.Credentials = localNetworkCredential;*/
Stream memStream = new System.IO.MemoryStream();
byte[] boundarybytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" +
boundary + "\r\n");
string formdataTemplate = "\r\n--" + boundary +
"\r\nContent-Disposition: form-data; name=\"{0}\";\r\n\r\n{1}";
foreach (string key in nvc.Keys)
{
string formitem = string.Format(formdataTemplate, key, nvc[key]);
byte[] formitembytes = System.Text.Encoding.UTF8.GetBytes(formitem);
memStream.Write(formitembytes, 0, formitembytes.Length);
}
memStream.Write(boundarybytes, 0, boundarybytes.Length);
string headerTemplate = "Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\n Content-Type: application/octet-stream\r\n\r\n";
for (int i = 0; i < files.Length; i++)
{
string header = string.Format(headerTemplate, "file" + i, files[i]);
//string header = string.Format(headerTemplate, "uplTheFile", files[i]);
byte[] headerbytes = System.Text.Encoding.UTF8.GetBytes(header);
memStream.Write(headerbytes, 0, headerbytes.Length);
FileStream fileStream = new FileStream(files[i], FileMode.Open,
FileAccess.Read);
byte[] buffer = new byte[1024];
int bytesRead = 0;
while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0)
{
memStream.Write(buffer, 0, bytesRead);
}
memStream.Write(boundarybytes, 0, boundarybytes.Length);
fileStream.Close();
}
httpWebRequest2.ContentLength = memStream.Length;
Stream requestStream = httpWebRequest2.GetRequestStream();
memStream.Position = 0;
byte[] tempBuffer = new byte[memStream.Length];
memStream.Read(tempBuffer, 0, tempBuffer.Length);
memStream.Close();
requestStream.Write(tempBuffer, 0, tempBuffer.Length);
requestStream.Close();
//Gets the response
WebResponse webResponse2 = httpWebRequest2.GetResponse();
Stream stream2 = webResponse2.GetResponseStream();
StreamReader reader2 = new StreamReader(stream2);
//Retrieve the html from response
string htmlResponse = reader2.ReadToEnd();
webResponse2.Close();
httpWebRequest2 = null;
webResponse2 = null;
}
}
我对此解决方案的问题是,当我上传文件并检索WebResponse时,我得到的页面是包含上传表单的页面,而不是上传后显示的页面,该页面成功的消息。
在我试图上传文件的页面上,我有这个html / form:
<FORM METHOD="POST" ENCTYPE="multipart/form-data" ACTION="uploadstatus.asp">
<INPUT TYPE="FILE" SIZE="40" NAME="FILE1"> <INPUT TYPE=SUBMIT VALUE="Upload!">
</FORM>
当我运行我的代码时,我每次都会得到同样的表格,好像我从来没有张贴任何东西......任何人都知道发生了什么事?
