Question

我想知道如何将您的NSURL更新为您的网址将重定向到的最后一个网址使用NSURL或NSRequest

感谢您的帮助。感谢。

Answer 1

zanque的解决方案有效，但为了避免下载“无用”数据，我将http方法更改为HEAD：

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:orinigalURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:15.0];
[request setHTTPMethod:@"HEAD"];
NSURLResponse *response = nil;
[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:nil];
NSURL *finalURL = response.URL;

Answer 2

我做到了，

这是如何

NSURL *originalUrl=[NSURL URLWithString:@"http://YourURL.com"];
NSData *data=nil;  
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:originalUrl cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10];
NSURLResponse *response;
NSError *error;
data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSURL *LastURL=[response URL];
[request release];
[error release];

Answer 3

尝试使用NSURLConnection进行连接后，您才能找到它。如果向NSURLConnection委托添加方法，-connection：willSendRequest：redirectResponse：，则会在重定向发生之前通知您。只需从传递的请求中获取URL，这就是您的答案。

Answer 4

您导致以下快速代码获取最终的重定向网址：

            let request = NSMutableURLRequest(url: url, cachePolicy: .reloadIgnoringCacheData, timeoutInterval: 15.0)
        request.httpMethod = "HEAD"
        var response: URLResponse? = nil
        do {
            try NSURLConnection.sendSynchronousRequest(request as URLRequest, returning: &response)
        } catch { //Handle exception //if any
        }
        let finalURL = response?.url
