[英]NSURLSession HTTP basic auth delegate does not work
I used NSURLConnection
with challenge delegate, and it worked. 我将NSURLConnection
与质询委托一起使用,并且有效。 I now migrate my code to session, and challenge not called. 现在,我将代码迁移到会话,并且未调用挑战。 On server side I see 401 response, but no delegate called. 在服务器端,我看到401响应,但未调用任何委托。
@interface MyDelegate : NSObject<NSURLSessionDelegate, NSURLSessionTaskDelegate>
@end
@implementation MyDelegate
- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge
completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential * __nullable credential))completionHandler {
// Break point here NOT called
}
- (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task
didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge
completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential * __nullable credential))completionHandler {
// Break point here NOT called
}
@end
int main(int argc, char * argv[]) {
@autoreleasepool {
//return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
NSURL *url = [NSURL URLWithString:@"http://127.0.0.1:8000/upload/123"];
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
req.HTTPMethod = @"PUT";
[req setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
NSError *err;
NSURLResponse *resp;
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration] delegate:[MyDelegate new] delegateQueue:nil];
[[session uploadTaskWithRequest:req fromData:[NSData new]]resume];
sleep(10000);
}
}
Do I miss something? 我想念什么吗?
Just in case: please do not advice me to create Basic HTTP auth header manually, I want to use delegate. 以防万一:请不要建议我手动创建Basic HTTP auth标头,我想使用委托。
PS: Could it be my delegate released since delegate not retained in session? PS:那是因为未派代表参加会议而释放了我的代表吗? I will try to make it static, then. 然后,我将尝试使其变为静态。
I think NSURLSession requests have to be running in a run loop. 我认为NSURLSession请求必须在运行循环中运行。 I'm not certain of this, however. 但是,我不确定。
And of course, if you were doing this in a real app, you probably would not want to block the main thread with a sleep call. 当然,如果您在真实的应用程序中执行此操作,则可能不希望通过sleep调用来阻塞主线程。 This might also be part of the problem. 这也可能是问题的一部分。
