ios 获取head数据

NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
    NSArray *_tmpArray = [NSArray arrayWithArray:[cookieJar cookies]];
        NSLog(@"obj == %@",[_tmpArray objectAtIndex:0]);
   
    for (int i = 0; i < [_tmpArray count]; i++)
       
    {
        NSHTTPCookie *cookie = [_tmpArray objectAtIndex:i];
        NSLog(@"%@",[cookie value]);
       
        [USER_DEFAULT setObject:[cookie value] forKey:@"SID"];
        [USER_DEFAULT synchronize];
    }

self.req = [[ASIHTTPRequest alloc]initWithURL:[NSURL URLWithString:urlStr]];

        NSMutableDictionary *tempDictHead = [[NSMutableDictionaryalloc]initWithCapacity:10];

        [tempDictHead setObject:@"XMLHttpRequest"forKey:@"X-Requested-With"];

        self.req.requestHeaders = tempDictHead;

        self.req.delegate = self;

        [self.req setDidFinishSelector:@selector(success:)];

        [self.req setDidFailSelector:@selector(loginFailed:)];

        [self.reqstartAsynchronous];

 

 

 

 

+(void)creatRequest:(NSString *)urlString paramDict:(NSMutableDictionary *)paramDict delegate:(id)delegate{

//    NSLog(@"paramDict====%@",paramDict);

    ASIFormDataRequest *requestForm = [[ASIFormDataRequest alloc] initWithURL:[NSURL URLWithString:urlString]];

    if (! [delegate isKindOfClass:[UIView class]]) {

        BaseViewController *baseVc = (BaseViewController*)delegate;

        baseVc.formDataRequest = requestForm;

    }

    

    for (id key in [paramDict keyEnumerator])

    {

//        NSLog(@"===++===%@",[paramDict objectForKey:key]);

        [requestForm setPostValue:[paramDict objectForKey:key] forKey:key];

    }

//    requestForm.HEADRequest = @"X-Requested-With:XMLHttpRequest";

    

    [requestForm setDelegate:delegate];

 

    [requestForm startAsynchronous];

 

 

如果是后面一种应该在  ASIFormDataRequest.m里面的 - (void)buildURLEncodedPostBody 方法里面加入：

 

[selfaddRequestHeader:@"X-Requested-With"value:@"XMLHttpRequest"];
