自实现的cookie 验证，远程取值的例子



以下代码配合HttpClient使用可以实现跨域(cookie的读写)

//验证


	复制代码 代码如下:

	

	HttpClient httpClient = new HttpClient(url, null, true);

	httpClient.PostingData.Add(key,value);//登录用户名

	httpClient.PostingData.Add(key,value);//密码

	string str = httpClient.GetString();


----写文件 序列化传回来的cookie


	复制代码 代码如下:

	

	CookieCollection cookies = httpClient.Context.Cookies;//保存一个全局的cookie文件

	FileStream fileStream = new FileStream("xxx.dat", FileMode.Create);

	BinaryFormatter b = new BinaryFormatter();

	b.Serialize(fileStream, cookies);

	fileStream.Close();


--读文件 反序列化cookies 赋给httpClient的cookies


	复制代码 代码如下:

	

	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();
