在给一些客户端做服务器端支持时，发现他们提交上来的数据大都不是http请求格式，因而使用Request.Form获取不到内容，今天用C#做下模拟，并演示下数据接收。

1.发送文本

1).客户端发送文本

复制内容到剪贴板程序代码 using System;
using System.IO;
using System.Net;
using System.Text;

namespace ConsoleApplication1
{
????class Program
????{
????????static void Main(string[] args)
????????{
????????????Console.WriteLine(Post("http://localhost/Test", "木子屋", Encoding.UTF8));
????????????Console.ReadKey();
????????}

????????/// <summary>
????????/// 发送文本
????????/// </summary>
????????/// <param name="url"></param>
????????/// <param name="data"></param>
????????/// <param name="encoding"></param>
????????/// <returns></returns>
????????public static string Post(string url, string data, Encoding encoding)
????????{
????????????byte[] bytes = encoding.GetBytes(data);
????????????HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
????????????request.Method = "POST";
????????????request.ContentLength = bytes.Length;
????????????using (Stream stream = request.GetRequestStream())
????????????{
????????????????stream.Write(bytes, 0, bytes.Length);
????????????}
????????????HttpWebResponse response = (HttpWebResponse)request.GetResponse();
????????????using (StreamReader stream = new StreamReader(response.GetResponseStream(), encoding))
????????????{
????????????????return stream.ReadToEnd();
????????????}
????????}
????}
}
2).服务器端接收文本

复制内容到剪贴板程序代码 string str = "";
using (StreamReader stream = new StreamReader(Request.InputStream))
{
????str = stream.ReadToEnd();
}
说明：只需增加request.ContentType = "application/x-www-form-urlencoded"，并将文本格式改为"data=木子屋"，服务器端即可用Request.Form["data"]接收。

2.上传文件

1).客户端上传文件

复制内容到剪贴板程序代码 using System;
using System.IO;
using System.Net;
using System.Text;

namespace ConsoleApplication1
{
????class Program
????{
????????static void Main(string[] args)
????????{
????????????Console.WriteLine(UploadFile("http://localhost/Test", @"E:\test.jpg"));
????????????Console.ReadKey();
????????}

????????/// <summary>
????????/// 上传文件
????????/// </summary>
????????/// <param name="url"></param>
????????/// <param name="file"></param>
????????/// <returns></returns>
????????public static string UploadFile(string url, string file)
????????{
????????????//1.HttpWebRequest
????????????HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
????????????request.Method = "POST";
????????????using (Stream stream = request.GetRequestStream())
????????????{
????????????????using (FileStream fileStream = new FileStream(file, FileMode.Open, FileAccess.Read))
????????????????{
????????????????????byte[] buffer = new byte[4096];
????????????????????int bytesRead = 0;
????????????????????while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0)
????????????????????{
????????????????????????stream.Write(buffer, 0, bytesRead);
????????????????????}
????????????????}
????????????}
????????????//2.HttpWebResponse
????????????HttpWebResponse response = (HttpWebResponse)request.GetResponse();
????????????using (StreamReader stream = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
????????????{
????????????????return stream.ReadToEnd();
????????????}
????????}
????}
}
2).服务器端接收文件

复制内容到剪贴板程序代码 using (FileStream file = System.IO.File.Create(Request.MapPath("test.jpg")))
{
????using (BinaryReader stream = new BinaryReader(Request.InputStream))
????{
????????byte[] buffer = new byte[4096];
????????int bytesRead = 0;
????????while ((bytesRead = stream.Read(buffer, 0, buffer.Length)) != 0)
????????{
????????????file.Write(buffer, 0, bytesRead);
????????}
????}
} ?
