NSMutableURLRequest和重定向 [英] NSMutableURLRequest and redirection

问题描述

所以我正在尝试创建一个请求，该请求将自动跟踪其进程中的重定向。由于某种原因，这不起作用，这是我的委托方法的样子。我还需要做其他事情才能正常运作吗？谢谢！

   - （NSURLRequest *）连接：（NSURLConnection *）连接
 willSendRequest：（NSURLRequest *）request 
 redirectResponse：（NSURLResponse *）redirectResponse {
 NSLog（@RedirectResponse：％@，[redirectResponse URL]）; 
 NSLog（@发送请求：％@，[请求URL]）; 
 
 NSHTTPCookieStorage * cookieDict = [NSHTTPCookieStorage sharedHTTPCookieStorage]; 
 NSLog（@CURRENT COOKIES：％@，[cookieDict cookies]）; 
 
 / * NSHTTPURLResponse * httpResponse =（NSHTTPURLResponse *）redirectResponse; 
 if（[redirectResponse respondsToSelector：@selector（allHeaderFields）]）{
 NSDictionary * dictionary = [httpResponse allHeaderFields]; 
 NSLog（[字典描述]）; 
} * / 
 
 NSURLRequest * newRequest = request; 
返回newRequest; 
  

}

解决方案

文档说：

委托可以返回未修改的请求以允许重定向

所以一个简单的返回请求; 就足够了。

<你确定它不起作用吗？你看到了什么？

So I am trying to create a request that will automatically follow the redirects in its process. For some reason this is not working, this is what my delegate method looks like. Do I need to do anything else for this to function properly? Thanks!

-(NSURLRequest *)connection:(NSURLConnection *)connection
        willSendRequest:(NSURLRequest *)request
       redirectResponse:(NSURLResponse*)redirectResponse {
NSLog(@"RedirectResponse:%@", [redirectResponse URL]);
NSLog(@"send request:%@", [request URL]);

NSHTTPCookieStorage *cookieDict = [NSHTTPCookieStorage sharedHTTPCookieStorage];
NSLog(@"CURRENT COOKIES: %@", [cookieDict cookies]);

/*NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*)redirectResponse;
if ([redirectResponse respondsToSelector:@selector(allHeaderFields)]) {
    NSDictionary *dictionary = [httpResponse allHeaderFields];
    NSLog([dictionary description]);
}*/

NSURLRequest *newRequest=request; 
return newRequest;

}

解决方案

The documentation says:

The delegate may return request unmodified to allow the redirect

So a simple return request; should be enough.

Are you sure it is not working? What do you see?
