C# 利用HttpClient解決Cookie驗證問題

自實現的cookie 驗證，遠程取值的例子   http://www.cnblogs.com/deerchao/archive/2007/08/09/849361.html 該地址下載HttpClient類   以下代碼配合HttpClient使用可以實現跨域(cookie的讀寫)  //驗證 HttpClient httpClient = new HttpClient(url, null, true); httpClient.PostingData.Add(key,value);//登錄用戶名 httpClient.PostingData.Add(key,value);//密碼 string str = httpClient.GetString(); ----寫文件 序列化傳回來的cookie  CookieCollection cookies = httpClient.Context.Cookies;//保存一個全局的cookie文件 FileStream fileStream = new FileStream("xxx.dat", FileMode.Create); BinaryFormatter b = new BinaryFormatter(); b.Serialize(fileStream, cookies); fileStream.Close();   --讀文件 反序列化cookies 賦給httpClient的cookies FileStream fileStream = new FileStream("xxx.dat", FileMode.Open, FileAccess.Read, FileShare.Read); BinaryFormatter b = new BinaryFormatter(); CookieCollection cookies = b.Deserialize(fileStream) as CookieCollection; HttpClient httpClient = new HttpClient("url");//取值的url httpClient.Context.Cookies = cookies; string str = httpClient.GetString();
