Question

我正在构建一个带有cookie的iPhone应用程序。在Safari设置中删除Cookie不会删除它们。它们存放在哪里？是否可以从另一个UIWebView中读取它们？

谢谢！

Answer 1

您的应用程序在[NSHTTPCookieStorage sharedHTTPCookieStorage]容器中有自己的“cookie jar”。

以下是如何快速查看应用程序的cookie jar中的cookie：

NSHTTPCookie *cookie;
NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [cookieJar cookies]) {
   NSLog(@"%@", cookie);
}

有几种方法可用于过滤和操作。查看用于访问cookie的NSHTTPCookieStorage文档，以及用于访问各个cookie属性的NSHTTPCookie文档。

感谢指针Alex！为了补充这一点，我将放入我使用Alex的示例创建的“cookie dumper”。也许这会帮助别人。

- (void) dumpCookies:(NSString *)msgOrNil {
NSMutableString *cookieDescs    = [[[NSMutableString alloc] init] autorelease];
NSHTTPCookie *cookie;
NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [cookieJar cookies]) {
    [cookieDescs appendString:[self cookieDescription:cookie]];
}
NSLog(@"------ [Cookie Dump: %@] ---------\n%@", msgOrNil, cookieDescs);
NSLog(@"----------------------------------");
}

- (NSString *) cookieDescription:(NSHTTPCookie *)cookie {

NSMutableString *cDesc      = [[[NSMutableString alloc] init] autorelease];
[cDesc appendString:@"[NSHTTPCookie]\n"];
[cDesc appendFormat:@"  name            = %@\n",            [[cookie name] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
[cDesc appendFormat:@"  value           = %@\n",            [[cookie value] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
[cDesc appendFormat:@"  domain          = %@\n",            [cookie domain]];
[cDesc appendFormat:@"  path            = %@\n",            [cookie path]];
[cDesc appendFormat:@"  expiresDate     = %@\n",            [cookie expiresDate]];
[cDesc appendFormat:@"  sessionOnly     = %d\n",            [cookie isSessionOnly]];
[cDesc appendFormat:@"  secure          = %d\n",            [cookie isSecure]];
[cDesc appendFormat:@"  comment         = %@\n",            [cookie comment]];
[cDesc appendFormat:@"  commentURL      = %@\n",            [cookie commentURL]];
[cDesc appendFormat:@"  version         = %d\n",            [cookie version]];

//  [cDesc appendFormat:@"  portList        = %@\n",            [cookie portList]];
//  [cDesc appendFormat:@"  properties      = %@\n",            [cookie properties]];

return cDesc;
}

亚历克斯有一个很好的想法，把它放在一个类别。这是我最终使用的内容：

NSHTTPCookieStorage + Info.h

#import <Foundation/Foundation.h>

@interface NSHTTPCookieStorage (Info)

+ (NSDictionary*) describeCookies;
+ (NSDictionary *) describeCookie:(NSHTTPCookie *)cookie;

@end

NSHTTPCookieStorage.m

@implementation NSHTTPCookieStorage (Info)

+ (NSDictionary*) describeCookies {
    NSMutableDictionary *descriptions = [NSMutableDictionary new];

    [[[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies] enumerateObjectsUsingBlock:^(NSHTTPCookie* obj, NSUInteger idx, BOOL *stop) {
        [descriptions setObject:[[self class] describeCookie:obj] forKey:[[obj name] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
    }];

    NSLog(@"Cookies:\n\n%@", descriptions);
    return descriptions;
}

+ (NSDictionary *) describeCookie:(NSHTTPCookie *)cookie {
    return @{@"value" : [[cookie value] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding],
         @"domain" : [cookie domain] ? [cookie domain]  : @"n/a",
         @"path" : [cookie path] ? [cookie path] : @"n/a",
         @"expiresDate" : [cookie expiresDate] ? [cookie expiresDate] : @"n/a",
         @"sessionOnly" : [cookie isSessionOnly] ? @1 : @0,
         @"secure" : [cookie isSecure] ? @1 : @0,
         @"comment" : [cookie comment] ? [cookie comment] : @"n/a",
         @"commentURL" : [cookie commentURL] ? [cookie commentURL] : @"n/a",
         @"version" : @([cookie version]) };

}

@end

使输出更多“JSON-y”......

在sandbox:Library->Cookies->Cookies.binarycookies中但您不能直接打开.binarycookie，可以运行脚本：

下载并安装Python
下载BinaryCookieReader.py
在终端上运行“ Python BinaryCookieReader.py”

如您所见，输出日志包含详细的cookie描述

UIWebView的cookie存储在哪里？
