C# HttpClient Cookie驗證解決方案

自實現的cookie 驗證，遠程取值的例子

以下代碼配合HttpClient使用可以實現跨域(cookie的讀寫)
//驗證 複製代碼 代碼如下:HttpClient httpClient = new HttpClient(url, null, true);
httpClient.PostingData.Add(key,value);//登入使用者名稱
httpClient.PostingData.Add(key,value);//密碼
string str = httpClient.GetString();

----寫檔案 序列化傳回來的cookie 複製代碼 代碼如下:CookieCollection cookies = httpClient.Context.Cookies;//儲存一個全域的cookie檔案
FileStream fileStream = new FileStream("xxx.dat", FileMode.Create);
BinaryFormatter b = new BinaryFormatter();
b.Serialize(fileStream, cookies);
fileStream.Close();

--讀檔案 還原序列化cookies 賦給httpClient的cookies 複製代碼 代碼如下: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();
