这段代码
using (WebClient webClient = new WebClient())
{
string address = "https://www.any.com/name.htm";
byte[] postData = Encoding.ASCII.GetBytes("login=123");
webClient.Headers[HttpRequestHeader.Accept] = "text/html, application/xhtml+xml, */*";
webClient.Headers[HttpRequestHeader.AcceptLanguage] = "ru-RU";
webClient.Headers[HttpRequestHeader.UserAgent] = "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)";
webClient.Headers[HttpRequestHeader.AcceptEncoding] = "gzip, deflate";
webClient.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
webClient.UploadData(address, postData);
}
产生这个请求(postData 双打):
POST /name.htm HTTP/1.1
Accept-Language: ru-RU
Accept-Encoding: gzip, deflate
Accept: text/html, application/xhtml+xml, */*
Content-Type: application/x-www-form-urlencoded
User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)
Host: [url]www.any.com[/url]
Content-Length: 9
Connection: Keep-Alive
login=123login=123
如果我改变
string address = "https://www.any.com/name.htm"
至
string address = "http://www.any.com/name.htm"
那么数据不会翻倍。
HTTPS发送请求时如何避免数据翻倍?
