高手帮我测试下吧,我需要通过程序来登录网页
地址是:http://www.inang.cn/blog/login.asp
用户名:test
密码:testtest代码如下,为什么手工可以登录,代码却登录不了
string uriString = "http://www.inang.cn/blog/login.asp?act=login";
string postString = "userName=test&password=testtest&Login=Login&CookiesDay=1";WebClient webClient = new WebClient();
webClient.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
byte[] postData = Encoding.ASCII.GetBytes(postString);
byte[] responseData = webClient.UploadData(uriString, "POST", postData);
string srcString = Encoding.UTF8.GetString(responseData);
