使用 NSURLSession 设置 cookie

您好，我正在开发一个 Iphone 应用程序，我想在服务器响应后设置 cookie 并将其用于另一个请求。我的网络请求看起来像。

NSURLSession *session = [NSURLSession sharedSession];
[[session dataTaskWithURL:url completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
{
    NSHTTPURLResponse *httpResp = (NSHTTPURLResponse*) response;
    NSLog(@"sttaus code %i", httpResp.statusCode);
    if (error) {
        [self.delegate signinWithError:error];
    }
    else {
        [self.delegate signinWithJson:data];
    }
}] resume];

但我不知道如何设置cookie。我知道我必须使用NSHTTPCookieStorage但我不知道如何设置。我还想将该 cookie 用于另一个请求。有没有人知道这件事？需要帮忙。谢谢。

看看我尝试过这种方式

NSURLSession *session = [NSURLSession sharedSession];
[[session dataTaskWithURL:url completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
{      
    if(error) {
        [self.delegate signinWithError:error];
    }
    else {
        NSHTTPURLResponse *httpResp = (NSHTTPURLResponse*) response;

        [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];
        NSHTTPCookie *cookie;

        NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];

        NSDictionary* headers = [(NSHTTPURLResponse *)response allHeaderFields];

        for(NSString *key in [headers allKeys]) {
            NSLog(@"%@ ..PPPP ... %@",key ,[headers objectForKey:key]);
            [cookieProperties setObject:[headers objectForKey:key] forKey:key];
        }

        [cookieProperties setObject:[[NSDate date] dateByAddingTimeInterval:2629743] forKey:NSHTTPCookieExpires];

        cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];
        [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];

        [self.delegate signinWithJson:data];
    }
}] resume];

我只对一个标头字段感兴趣Set-Cookie SSID=kgu62c0fops35n6qbf12anqlo7; path=/

您可能只需使用sharedHTTPCookieStorage https://developer.apple.com/library/ios/documentation/Cocoa/Reference/Foundation/Classes/NSHTTPCookieStorage_Class/Reference/Reference.html#//apple_ref/occ/clm/NSHTTPCookieStorage/sharedHTTPCookieStorage for NSHTTPCookieStorage https://developer.apple.com/library/ios/documentation/Cocoa/Reference/Foundation/Classes/NSHTTPCookieStorage_Class/Reference/Reference.html，然后使用setCookies:forURL:mainDocumentURL: https://developer.apple.com/library/ios/documentation/Cocoa/Reference/Foundation/Classes/NSHTTPCookieStorage_Class/Reference/Reference.html#//apple_ref/occ/instm/NSHTTPCookieStorage/setCookies:forURL:mainDocumentURL:或单个setCookie: https://developer.apple.com/library/ios/documentation/Cocoa/Reference/Foundation/Classes/NSHTTPCookieStorage_Class/Reference/Reference.html#//apple_ref/doc/uid/20001703-CJBDADAC- 后者可能更适合您的需求。

如果这不起作用，您可能需要设置NSURLSessionConfiguration https://developer.apple.com/library/ios/documentation/Foundation/Reference/NSURLSessionConfiguration_class/Reference/Reference.html#//apple_ref/doc/c_ref/NSURLSessionConfiguration并设置NSHTTPCookieStorage https://developer.apple.com/library/ios/documentation/Foundation/Reference/NSURLSessionConfiguration_class/Reference/Reference.html#//apple_ref/occ/instp/NSURLSessionConfiguration/HTTPCookieStorage

文档没有说明，但是defaultSessionConfiguration https://developer.apple.com/library/ios/documentation/Foundation/Reference/NSURLSessionConfiguration_class/Reference/Reference.html#//apple_ref/occ/clm/NSURLSessionConfiguration/defaultSessionConfiguration无论如何，可能会使用共享存储。

NSURLSession *session = [NSURLSession sharedSession];
[[session dataTaskWithURL:url completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
{
    NSHTTPURLResponse *httpResp = (NSHTTPURLResponse*) response;

    NSArray *cookies = [NSHTTPCookie cookiesWithResponseHeaderFields:[response allHeaderFields] forURL:[response URL]];
    [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookies:cookies forURL:[response URL] mainDocumentURL:nil];

    NSLog(@"sttaus code %i", httpResp.statusCode);
    if (error) {
        [self.delegate signinWithError:error];
    }
    else {
        [self.delegate signinWithJson:data];
    }
}] resume];
