UIWebView的cookie存储在哪里？
UIWebView的cookie存储在哪里？
提问于 2009-04-21 07:49:04
我正在使用cookies构建一个iPhone应用程序。在Safari设置中删除cookies不会删除它们。它们存储在哪里？是否可以从另一个UIWebView读取它们？
谢谢!

您的应用程序在[NSHTTPCookieStorage sharedHTTPCookieStorage]容器中有自己的"cookie jar“。
下面是如何快速查看应用程序cookie jar中的cookie的方法：
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。

谢谢你的指点，Alex！为了补充这一点，我将放入我使用Alex的示例创建的"cookie dumper“。也许这对其他人有帮助。
- (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;

Alex有一个很好的想法，可以把它归入一个类别。以下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;
@endNSHTTPCookieStorage.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使输出更像"JSON-y"...
