}
错误的会返回
--------------------编程问答-------------------- 代码还存在如下问题：他得POST 编码是gzip(Accept-Encoding:gzip,deflate,sdch)
request.Headers[HttpRequestHeader.AcceptEncoding] = "gzip,deflate,sdch";
但是看它的内容大小又是18，如果不对 cardcode:z3c26b82f 这串字符进行 GZipStream 编码，大小刚好是18
如果对其压缩，压缩后会有一些特定的头,byte[] 数组大小为137。
我不是很明白 他发送出去POST 数据是否压缩过，我压缩和不压缩这种方式都试了，依然返回结果是报该代金卷不存在
--------------------编程问答--------------------
public void SetHeaderValue(WebHeaderCollection header, string name, string value)
{
var property = typeof(WebHeaderCollection).GetProperty("InnerCollection",
System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
if (property != null)
{
var collection = property.GetValue(header, null) as NameValueCollection;
collection[name] = value;
}
}
反射那段方法发掉了 --------------------编程问答--------------------
补充：.NET技术 , ASP.NET
