问题描述
我希望有人能够阐明以下几点，我想我正在朝着正确的方向前进。我想用一个用户/密码组合登录到我的服务器，然后我需要能够告诉我是否正确登录（应该删除一个cookie），如果是这种情况，我会提出另一个请求。
任何帮助表示感谢，继承人我正在使用的代码：
[[ NSHTTPCookieStorage sharedHTTPCookieStorage] setCookieAcceptPolicy：NSHTTPCookieAcceptPolicyAlways]; NSString * post = [NSString stringWithFormat：@name =％@&pass =％@，@foo，@bar]; NSData * postData = [post dataUsingEncoding：NSASCIIStringEncoding allowLossyConversion：YES]; NSString * postLength = [NSString stringWithFormat：@％d，[postData length]]; NSMutableURLRequest * request = [[[[NSMutableURLRequest alloc] init] autorelease]; [request setURL：[NSURL URLWithString：@www.mywebserver/login.php]]; [request setHTTPMethod：@POST]; [request setValue：postLength forHTTPHeaderField：@Content-Length]; [request setValue：@application / x-www-form-urlencodedforHTTPHeaderField：@Content-Type]; [request setHTTPBody：postData]; NSError *错误; NSURLResponse *响应; NSData * urlData = [NSURLConnection sendSynchronousRequest：request returningResponse：& response error：& error]; NSString * data = [[NSString alloc] initWithData：urlData encoding：NSUTF8StringEncoding]; NSLog（data）; //如何检查Cookie是否被删除？ //发出另一个请求..解决方案
这应该可以工作：
NSDictionary * headerFields = [（NSHTTPURLResponse *）response allHeaderFields]; NSURL * url = [NSURL URLWithString：@www.mywebserver/login.php]; NSArray * cookies = [NSHTTPCookie cookiesWithResponseHeaderFields：headerFields forURL：url];然后您就可以知道 cookies 数组包含你想要的cookie。
您也可以在收到回复后调用它：
NSArray * cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL：url];
I'm hoping someone can shed some light on the following, I think I am heading in the right direction with this. I want to login to my server with a user/pass combo, then I need to be able to tell If I logged in correctly (a cookie should be dropped), then I will make another request if this is the case.
Any help appreciated, heres the code I am working with:
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways]; NSString *post =[NSString stringWithFormat:@"name=%@&pass=%@",@"foo", @"bar"]; NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:@"www.mywebserver/login.php"]]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; NSError *error; NSURLResponse *response; NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; NSString *data=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding]; NSLog(data); // HOW to Check if there was a Cookie dropped?? // Make another request..解决方案
This should work:
NSDictionary *headerFields = [(NSHTTPURLResponse*)response allHeaderFields]; NSURL *url = [NSURL URLWithString:@"www.mywebserver/login.php"]; NSArray *cookies = [NSHTTPCookie cookiesWithResponseHeaderFields:headerFields forURL:url];Then you can know if the cookies array contains the cookie you want.
You could also call this after receiving the response:
NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:url];
