获取“位置"来自NSHTTPURLResponse的标头 [英] Getting "Location" header from NSHTTPURLResponse

问题描述

根本无法从响应中获取"Location"标头. Wireshark说我有一个:

Can't get "Location" header from response at all. Wireshark says that i've got one:

位置: http://*/index.html#0; sid = 865a84f0212a3a35d8e9d5f68398e535

Location: http://*/index.html#0;sid=865a84f0212a3a35d8e9d5f68398e535

但是

NSHTTPURLResponse *hr = (NSHTTPURLResponse*)response;
NSDictionary *dict = [hr allHeaderFields];          
NSLog(@"HEADERS : %@",[dict description]);

产生这个:

HEADERS : {
    Connection = "keep-alive";
    "Content-Encoding" = gzip;
    "Content-Type" = "text/html";
    Date = "Thu, 25 Mar 2010 08:12:08 GMT";
    "Last-Modified" = "Sat, 29 Nov 2008 15:50:54 GMT";
    Server = "nginx/0.7.59";
    "Transfer-Encoding" = Identity;
}

在任何地方都没有位置.如何获得?我需要这个"sid"东西.

No location anywhere. How to get it? I need this "sid" thing.

推荐答案

NSHTTPURLResponse是NSURLResponse的子类，因此您可以要求它提供URL.这将返回一个NSURL对象，您可以从中获取URL组件，例如查询，参数字符串或片段.在您的情况下，您需要片段组件:

NSHTTPURLResponse is a subclass of NSURLResponse so you can just ask it for its URL. This returns an NSURL object from which you can get the URL components such as the query, parameter string or fragment. In your case you want the fragment component:

NSURL* url = [response URL];
NSString* fragment = [url fragment];
//fragment should be: 0;sid=865a84f0212a3a35d8e9d5f68398e535
