导读：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.PostingD

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();
