使用httplistener监听来自客户端的http请求，对于Get请求的数据可以通过Request.QueryString["参数"]获取
而对于来自客户端的Post请求则不能使用Request[""]获取，需要将获取分析请求流中的数据拿到参数

开启监听，获取Post请求的参数
class Program
{
private static HttpListener httpPostRequest = new HttpListener();
static void Main(string[] args)
{
httpPostRequest.Prefixes.Add("http://10.0.0.217:30000/posttype/");
httpPostRequest.Start();
Thread ThrednHttpPostRequest = new Thread(new ThreadStart(httpPostRequestHandle));
ThrednHttpPostRequest.Start();
}
private static void httpPostRequestHandle()
{
while (true)
{
HttpListenerContext requestContext = httpPostRequest.GetContext();
Thread threadsub = new Thread(new ParameterizedThreadStart((requestcontext) =>
{
HttpListenerContext request = (HttpListenerContext)requestcontext;
//获取Post请求中的参数和值帮助类
HttpListenerPostParaHelper httppost=new HttpListenerPostParaHelper (request);
//获取Post过来的参数和数据
List<HttpListenerPostValue> lst=httppost.GetHttpListenerPostValue();
string userName = "";
string password = "";
string suffix = "";
string adType = "";
//使用方法
foreach (var key in lst)
{
if (key.type == 0)
{
string value = Encoding.UTF8.GetString(key.datas).Replace("\r\n", "");
if (key.name == "username")
{
userName = value;
Console.WriteLine(value);
}
if (key.name == "password")
{
password = value;
Console.WriteLine(value);
}
if (key.name == "suffix")
{
suffix = value;
Console.WriteLine(value);
}
if (key.name == "adtype")
{
adType = value;
Console.WriteLine(value);
}
}
if (key.type == 1)
{
string fileName = request.Request.QueryString["FileName"];
if (!string.IsNullOrEmpty(fileName))
{
string filePath = AppDomain.CurrentDomain.BaseDirectory + DateTime.Now.ToString("yyMMdd_HHmmss_ffff") + Path.GetExtension(fileName).ToLower();
if (key.name == "File")
{
FileStream fs = new FileStream(filePath, FileMode.Create);
fs.Write(key.datas, 0, key.datas.Length);
fs.Close();
fs.Dispose();
}
}
}
}
//Response
request.Response.StatusCode = 200;
request.Response.Headers.Add("Access-Control-Allow-Origin", "*");
request.Response.ContentType = "application/json";
requestContext.Response.ContentEncoding = Encoding.UTF8;
byte[] buffer = System.Text.Encoding.UTF8.GetBytes(Newtonsoft.Json.JsonConvert.SerializeObject(new {success="true",msg="提交成功" }));

HttpListener 类一定要在程序结束时手动结束掉（有时调试时，明明程序已经停止，但是监听事件却在后台默默运行），建议把监听事件写在一个线程中，这样的话假如线程停掉，里面的监听事件也就停掉了。 特别注意，因为是新手，我就自以为需要把IIS网站开启才能监听，但是在调试的时候却一直报”占用”错误，后来才慢慢试明白！ 另外，因为这次是做微信域名的验证，在微信请求时给微信相应的回复，刚开始就返回一个 true 可是微信说不行，后来整明白啦，原来需要回复的是微信绑定域名时的TXT文档中内容！ 这个大坑用了两天终于过去了
