利用字典NSMutableDictionary 转换为键/值格式的数据
初始化字典
NSMutableDictionary *cookieDict = [NSMutableDictionary dictionary];
获取当前页面的cookie，并将其转换为字典
NSArray *nCookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
NSHTTPCookie *cookie;
for (id c in nCookies){
if ([c isKindOfClass:[NSHTTPCookie class]]){
cookie=(NSHTTPCookie *)c;
[cookieDict setObject:cookie.value forKey:cookie.name];
}
}
NSLog(@"cookie...%@", cookieDict);
将字典转换为json串
//判断当前对象是否能够转换成JSON数据
BOOL isYes = [NSJSONSerialization isValidJSONObject:cookieDict];
if (isYes) {
NSLog(@"可以转换");
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:cookieDict options:0 error:NULL];
NSLog(@"%@", [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding]);
} else {
NSLog(@"JSON数据生成失败，请检查数据格式");
}
