释放双眼，带上耳机，听听看~！

1 NSMutableURLRequest请求时，会找到和该域名相同的cookie值，放到一起，然后请求。

2 [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie]; 不会在本地磁盘写入，只做内存缓存。

3 添加cookie

NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];

[cookieProperties setObject:@"authKey" forKey:NSHTTPCookieName];

[cookieProperties setObject:@".tabobao.com" forKey:NSHTTPCookieDomain];

[cookieProperties setObject:@"sfda" forKey:NSHTTPCookieValue];

[cookieProperties setObject:@"/" forKey:NSHTTPCookiePath];

[cookieProperties setObject:@"0" forKey:NSHTTPCookieVersion];

NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];

[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];

//添加cookie

NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];

for (NSHTTPCookie *tempCookie in cookies) {

NSLog(@"tep %@",tempCookie);

}

4 遍历cookie

NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];

for (NSHTTPCookie *tempCookie in cookies) {

NSLog(@"tep %@",tempCookie);

}

5 删除cookie

for (NSHTTPCookie *curCookie in [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]) {

[[NSHTTPCookieStorage sharedHTTPCookieStorage] deleteCookie:curCookie];

}

6测试代码

- (void)viewDidLoad {

[super viewDidLoad];

[self writeCookie];

[self testquest];

}

- (void)writeCookie{

NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];

[cookieProperties setObject:@"authKey" forKey:NSHTTPCookieName];

[cookieProperties setObject:@".taobao.com" forKey:NSHTTPCookieDomain];

[cookieProperties setObject:@"sfda" forKey:NSHTTPCookieValue];

[cookieProperties setObject:@"/" forKey:NSHTTPCookiePath];

[cookieProperties setObject:@"0" forKey:NSHTTPCookieVersion];

//添加cookie

NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];

[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];

NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];

for (NSHTTPCookie *tempCookie in cookies) {

NSLog(@"tep %@",tempCookie);

}

}

- (long long)testquest{

NSString *nsUrl = [NSString stringWithFormat:@"https://taobao.com"];

NSMutableURLRequest *nsmRequest = [[NSMutableURLRequest alloc] init] ;

[nsmRequest setURL:[NSURL URLWithString:nsUrl]];

[nsmRequest setHTTPMethod:@"HEAD"];

[nsmRequest setTimeoutInterval:30];

[nsmRequest addValue:[NSString stringWithFormat:@"text/html"] forHTTPHeaderField: @"Content-Type"];

[nsmRequest addValue:[NSString stringWithFormat:@"no-cache"] forHTTPHeaderField: @"Cache-Control"];

//get response

NSHTTPURLResponse* nsResponse = nil;

NSError *nsError = nil;

NSData *nsResponseData = nil;

@try

{

nsResponseData = [NSURLConnection sendSynchronousRequest:nsmRequest returningResponse:&nsResponse error:&nsError];

}

@catch (NSException * e)

{

return 0;

}

if( nsResponseData == nil )

{

if( -1001 == [nsError code] )

{

return 0;

}

return 0;

}

}

赋值代码后，使用Charles抓包就好。
