先建立一个WebApplication
Web.config
<?xml version="1.0" encoding="utf-8"?><configuration><system.web><!--<globalization requestEncoding="gb2312" responseEncoding="gb2312" fileEncoding="gb2312"/>--><compilation debug="true" /><authentication mode="Windows" /></system.web> </configuration>
Server.ashx
using System; using System.Data; using System.Web; using System.Collections; using System.Web.Services; using System.Web.Services.Protocols; using System.IO; using System.Text;namespace WebApplication1 {[WebService(Namespace = "http://tempuri.org/")][WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]public class Server : IHttpHandler{public void ProcessRequest(HttpContext context){try{string saveDirectory = @"f:\temp"; string user = context.Request.Form["user"].ToString();string pass = context.Request.Form["pass"].ToString();if (!(user == "abc" && pass == "123")){context.Response.Write("验证出错!");}HttpPostedFile postFile = context.Request.Files["myFile"];string postFileName = Path.GetFileName(postFile.FileName);byte[] bufferFile = new byte[postFile.ContentLength];postFile.InputStream.Read(bufferFile, 0, postFile.ContentLength);string savePath = Path.Combine(saveDirectory, postFileName);using (FileStream stream = new FileStream(savePath, FileMode.Create, FileAccess.Write)){stream.Write(bufferFile, 0, bufferFile.Length);stream.Flush();stream.Close();}context.Response.Write("提交成功!");}catch (Exception ex){ context.Response.Write(ex.Message);}}public bool IsReusable{get{return false;}}} }
选建个html测试下
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head><title>测试提交</title> </head> <body><form action="Server.ashx" enctype="multipart/form-data" method="post"><input type="text" name="user" value="abc" /><input type="text" name="pass" value="123"/><input type="file" name="myFile" /><input type="submit" /></form></body> </html>
再用C#按Http协议提交：
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.Net; using System.IO;namespace WinFormHttpPost {public partial class Form1 : Form{private Encoding currentEncode = Encoding.GetEncoding("utf-8");public Form1(){InitializeComponent();}private void Submit(string url, string user, string pass, string filePath){string boundary = Guid.NewGuid().ToString();string beginBoundary = "--" + boundary;string endBoundary = "--" + boundary + "--";HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);request.ContentType = "multipart/form-data; boundary=" + boundary;request.Method = "POST";request.KeepAlive = true;StringBuilder sbBody = new StringBuilder();sbBody.AppendLine(beginBoundary);sbBody.AppendLine("Content-Disposition: form-data; name=\"user\"");sbBody.AppendLine();sbBody.AppendLine(user);sbBody.AppendLine(beginBoundary);sbBody.AppendLine("Content-Disposition: form-data; name=\"pass\"");sbBody.AppendLine();sbBody.AppendLine(pass);sbBody.AppendLine(beginBoundary);sbBody.AppendLine(string.Format("Content-Disposition: form-data; name=\"myFile\"; filename=\"{0}\"", filePath));sbBody.AppendLine("Content-Type: application/octet-stream");sbBody.AppendLine();byte[] bufferContent = currentEncode.GetBytes(sbBody.ToString());byte[] bufferFile = GetFileByte(filePath);byte[] bufferEndBoundary = currentEncode.GetBytes("\r\n" + endBoundary);byte[] bufferBody = new byte[bufferContent.Length + bufferFile.Length + bufferEndBoundary.Length];int startIndex = 0;bufferContent.CopyTo(bufferBody, startIndex);startIndex += bufferContent.Length;bufferFile.CopyTo(bufferBody, startIndex);startIndex += bufferFile.Length;bufferEndBoundary.CopyTo(bufferBody, startIndex);request.ContentLength = bufferBody.Length;using (Stream requestStream = request.GetRequestStream()){requestStream.Write(bufferBody, 0, bufferBody.Length);}HttpWebResponse response = (HttpWebResponse)request.GetResponse();Stream receiveStream = response.GetResponseStream();StreamReader readStream = new StreamReader(receiveStream, currentEncode);tbResult.Text = readStream.ReadToEnd();response.Close();readStream.Close();}private byte[] GetFileByte(string filePath){byte[] bufferFileInfo = null;using (FileStream stream = new FileStream(filePath, FileMode.Open, FileAccess.Read)){bufferFileInfo = new byte[stream.Length];stream.Read(bufferFileInfo, 0, bufferFileInfo.Length);}return bufferFileInfo;}private void btnSubmit_Click(object sender, EventArgs e){Submit("http://localhost.:3558/Server.ashx", "abc", "123", "F:\\报表下载清单2.xls");}} }
