HttpWebRequest发送post请求问题
HttpWebRequest request = WebRequest.Create(uri) as HttpWebRequest;
//请求方式
request.Method = "POST";
//超时时间
//request.Timeout = 300000;
request.ContentType = "text/xml";
byte[] payload = Encoding.UTF8.GetBytes(message);
request.ContentLength = payload.Length;
//获得请求流
writer = request.GetRequestStream();
////将请求参数写入流
writer.Write(payload, 0, payload.Length);
//关闭请求流
writer.Flush();
writer.Close();
reader = new StreamReader(response.GetResponseStream());
string responseData = reader.ReadToEnd();
response.Close();
reader.Close();
代码如上所示，当我循环执行多次这个代码时，导致连接无法释放
查看端口效果如下：
求大神指教啊，急啊，当什么都不发的时候，循环多次没有任何问题
[解决办法]
response 那里冒出来的？你的代码完整
[解决办法]
public class Http
{
static Encoding m_Encoding = Encoding.Default;
public static string Get(string url)
{
return Proc(url, string.Empty);
}
public static string Post(string url, string data)
{
return Proc(url, data);
}
public static string Get(string url, List<NameValue> nameValues)
{
if (nameValues != null && nameValues.Count > 0)
{
string data = string.Join("&", nameValues.Select(o => string.Format("{0}={1}", o.Name, o.Value)).ToArray());
url = string.Format("{0}?{1}", url, data);
}
return Get(url);
}
public static string Post(string url, List<NameValue> nameValues)
{
string data = string.Empty;
if (nameValues != null && nameValues.Count > 0)
{
data = string.Join("&", nameValues.Select(o => string.Format("{0}={1}", o.Name, o.Value)).ToArray());
}
return Post(url, data);
}
private static HttpWebRequest CreateRequest(string url, string postData)
{
HttpWebRequest request = null;
request = (HttpWebRequest)WebRequest.Create(url);
request.Accept = "*/*";
request.ProtocolVersion = HttpVersion.Version11;
request.AllowAutoRedirect = true;
request.Timeout = 1000 * 30;
request.KeepAlive = true;
if (!string.IsNullOrEmpty(postData))
{
request.ContentType = "application/x-www-form-urlencoded";
request.Method = "POST";
byte[] bytes = m_Encoding.GetBytes(postData);
request.ContentLength = bytes.Length;
Stream requestStream = null;
try
{
requestStream = request.GetRequestStream();
requestStream.Write(bytes, 0, bytes.Length);
}
catch (Exception exception)
{
}
finally
{
if (requestStream != null)
{
requestStream.Close();
}
}
}
return request;
}
private static string Proc(string url, string postData)
{
HttpWebRequest request = CreateRequest(url, postData);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
using (StreamReader reader = new StreamReader(response.GetResponseStream(), m_Encoding))
{
string reHtml = reader.ReadToEnd();
reader.Close();
return reHtml;
}
}
}
public class NameValue
{
public NameValue(string name, string value)
{
this.Name = name;
this.Value = value;
}
public string Name { get; set; }
public string Value { get; set; }
}
DEMO
List<NameValue> list = new List<NameValue>();
list.Add(new NameValue("AreaID", macInfo.AreaID));
list.Add(new NameValue("Code", macInfo.Code));
list.Add(new NameValue("SortIndex", (macInfo.Index + 1).ToString()));
list.Add(new NameValue("Table", table));
list.Add(new NameValue("Slot", slot));
list.Add(new NameValue("SubSlot", subSlot));
list.Add(new NameValue("Lane", lane));
Http.Post(url,list)就是了
private static string Proc(string url, string postData)
{
HttpWebRequest request = CreateRequest(url, postData);
using( HttpWebResponse response = (HttpWebResponse)request.GetResponse()){
using (StreamReader reader = new StreamReader(response.GetResponseStream(), m_Encoding))
{
string reHtml = reader.ReadToEnd();
reader.Close();
return reHtml;
}
}}
