NSHTTPCookieStorage 数组 - 解析出值

Question

我在一个数组 (NSHTTPCookieStorage) 中有数据...

NSARRAY *httpCookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:aHttpUrl];

我知道有 3 个 cookie 被存储（我可以在 NSLog 中看到它们）。

我不知道如何根据“名称”获取 1 个特定的 cookie 值。

示例：<NSHTTPCookie version:0 name:\"username\" value:\"namehere\" expiresDate:2035-08-3 23:12:50 +0000 created:2015-08-08 23:12:49 +0000 (4.60768e+08) sessionOnly:FALSE domain:\"somedomain.com\" path:\"/example\" isSecure:FALSE>

...如何获取“value”的内容，以便将其作为字符串处理？

Answer 1

像这样

NSArray* cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:[NSURL URLWithString:YOUR_NETWORK_URL]];
for (NSHTTPCookie* cookie in cookies)
{
    NSLog(@"%@, ", [cookie valueForKey:@"version"]);
    NSLog(@"%@, ", [cookie valueForKey:@"name"]);

    NSString * this = [cookie valueForKey:@"name"];

    NSLog(@"%@, ", [cookie valueForKey:@"value"]);
    NSLog(@"%@, ", [cookie valueForKey:@"expiresDate"]);
    NSLog(@"%@, ", [cookie valueForKey:@"created"]);
    NSLog(@"%@, ", [cookie valueForKey:@"sessionOnly"]);
    NSLog(@"%@, ", [cookie valueForKey:@"domain"]);
    NSLog(@"%@, ", [cookie valueForKey:@"path"]);
    NSLog(@"%@, ", [cookie valueForKey:@"isSecure"]);
}

或 三个饼干，

 NSString * this1 =  [cookies[0] valueForKey:@"name"]
 NSString * this2 =  [cookies[1] valueForKey:@"name"]
 NSString * this3 =  [cookies[2] valueForKey:@"name"]

等等，等等，等等，这样做会使用键值的所有 cookie

操作 cookie：

NSString *alipaySetCookieString = @"CAKEPHP=nil; path=#; domain=#; expires=Wed, 30-Nov-2001 01:01:01 GMT";
NSHTTPCookie * clok  = [alipaySetCookieString cookie];

使用这个： 类别“NSString+Cookie.h”的标题

@interface NSString(Cookie)


- (NSHTTPCookie *)cookie;

@end

类别“NSString+Cookie.m”的实现文件

#import "NSString+Cookie.h"

@implementation NSString(Cookie)

- (NSDictionary *)cookieMap{
    NSMutableDictionary *cookieMap = [NSMutableDictionary dictionary];

    NSArray *cookieKeyValueStrings = [self componentsSeparatedByString:@";"];
    for (NSString *cookieKeyValueString in cookieKeyValueStrings) {
        NSRange separatorRange = [cookieKeyValueString rangeOfString:@"="];

        if (separatorRange.location != NSNotFound &&
            separatorRange.location > 0 &&
            separatorRange.location < ([cookieKeyValueString length] - 1)) { 
            NSRange keyRange = NSMakeRange(0, separatorRange.location);
            NSString *key = [cookieKeyValueString substringWithRange:keyRange];
            NSString *value = [cookieKeyValueString substringFromIndex:separatorRange.location + separatorRange.length];

            key = [key stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
            value = [value stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
            [cookieMap setObject:value forKey:key];

        }
    }
    return cookieMap;
}

- (NSDictionary *)cookieProperties {

    NSDictionary *cookieMap = [self cookieMap];

    NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];

            }
            [cookieProperties setObject:value forKey:NSHTTPCookieDomain];
        }else if ([uppercaseKey isEqualToString:@"VERSION"]) {

    if (![cookieProperties objectForKey:NSHTTPCookiePath]) {
