使用NSURLConnetion類的NSURLConnectionDataDelegate中的代理方法
- (nullable NSURLRequest *)connection:(NSURLConnection *)connection willSendRequest:(NSURLRequest *)request redirectResponse:(nullable NSURLResponse *)response
創(chuàng)建NSURLConnection對(duì)象發(fā)Request
NSURL *url = [NSURL URLWithString:@"http://c.snnd.co/api/v4/click?campaign_id=4410534&publisher_id=52&rt=170401034908&_po=4f6801b69d272e96bbb920659a2f805b&_mw=p&_c=972&_cw=c&_ad=1288&publisher_slot=260&sub_1=pst2977485&pub_gaid=&pub_idfa=ADB6E76C-6B91-455B-81BE-DB884CC17818&pub_aid=&sub_2=695-669-773_33_0.300_20131822574410534260_iOS_1491019272&sub_3=Y29tLmdtZWRhbC5nb2xkZ21lZGFsKG5hdDMp_US_hcvr.ecpm5_i-1.5.3___ADB6E76C-6B91-455B-81BE-DB884CC17818&ch=pst"];
NSMutableURLRequest *quest = [NSMutableURLRequest requestWithURL:url];
quest.HTTPMethod = @"GET";
NSURLConnection *connect = [NSURLConnection connectionWithRequest:quest delegate:self];
[connect start];
- (nullable NSURLRequest *)connection:(NSURLConnection *)connection willSendRequest:(NSURLRequest *)request redirectResponse:(nullable NSURLResponse *)response{
NSHTTPURLResponse *urlResponse = (NSHTTPURLResponse *)response;
NSLog(@"%ld",urlResponse.statusCode);
NSLog(@"%@",urlResponse.allHeaderFields);
NSDictionary *dic = urlResponse.allHeaderFields;
NSLog(@"%@",dic[@"Location"]);
return request;
}
控制臺(tái)輸出如下：request 是你要發(fā)送的請(qǐng)求 urlResponse.statusCode 則是請(qǐng)求的狀態(tài)碼,302則是重定向 。
urlResponse.allHeaderFields中保存著http的頭信息:
