摘要：C# HttpClient Cookie验证解决方法

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

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

[u]复制代码[/u] 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

[u]复制代码[/u] 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();
