我的应用程序使用NSURLConnection
与服务器进行通信。我们使用https进行通信。为了处理来自所有请求的身份验证,我使用了NSURLProtocol
,并在该类的代理中处理身份验证。现在我决定使用NSURLSession
而不是NSURLConnection
。我想做得到NSURLProtocol
与NSURLSession
工作,我创建了一个任务,并通过使用NSURLProtocol与NSURLSession
NSMutableURLRequest *sampleRequest = [[NSMutableURLRequest alloc]initWithURL:someURL];
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
configuration.protocolClasses = @[[CustomHTTPSProtocol class]];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
NSURLSessionDataTask *task = [session dataTaskWithRequest:checkInInfoRequest];
[task resume];
CustomHTTPSProtocol
这是我的NSURLProtocol
类看起来像这样
static NSString * const CustomHTTPSProtocolHandledKey = @"CustomHTTPSProtocolHandledKey";
@interface CustomHTTPSProtocol() <NSURLSessionDataDelegate,NSURLSessionTaskDelegate,NSURLSessionDelegate>
@property (nonatomic, strong) NSURLSessionDataTask *connection;
@property (nonatomic, strong) NSMutableData *mutableData;
@end
@implementation CustomHTTPSProtocol
+ (BOOL)canInitWithRequest:(NSURLRequest *)request {
if ([NSURLProtocol propertyForKey:CustomHTTPSProtocolHandledKey inRequest:request]) {
return NO;
}
return [[[[request URL]scheme]lowercaseString]isEqualToString:@"https"];
}
+ (NSURLRequest *)canonicalRequestForRequest:(NSURLRequest *)request {
return request;
}
- (void) startLoading {
NSMutableURLRequest *newRequest = [self.request mutableCopy];
[NSURLProtocol setProperty:@YES forKey:CustomHTTPSProtocolHandledKey inRequest:newRequest];
NSURLSession*session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration] delegate:self delegateQueue:nil];
self.connection = [session dataTaskWithRequest:newRequest];
[self.connection resume];
self.mutableData = [[NSMutableData alloc] init];
}
- (void) stopLoading {
[self.connection cancel];
self.mutableData = nil;
}
-(void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler {
NSLog(@"challenge..%@",challenge.protectionSpace.authenticationMethod);
if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) {
[challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
}
else {
[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}
}
- (void)URLSession:(NSURLSession *)session dataTask:(NSURLSessionDataTask *)dataTask didReceiveData:(NSData *)data {
[self.client URLProtocol:self didLoadData:data];
NSLog(@"data ...%@ ",data); //handle data here
[self.mutableData appendData:data];
}
- (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task didCompleteWithError:(NSError *)error {
if (!error) {
[self.client URLProtocolDidFinishLoading:self];
}
else {
NSLog(@"error ...%@ ",error);
[self.client URLProtocol:self didFailWithError:error];
}
}
@end
启动加载使用NSURLProtocol
被调用,也验证挑战完成后立即调用停止加载。
错误代码-999“取消”在一段时间后返回。 didReceiveData不被调用。
Note:NSURLProtocol and the Authentication Process worked fine with NSURLConnection.
我在想什么?我的问题是
注册[NSURLProtocol的registerClass:[CustomHTTPSProtocol类];在NSURLConnection中运行良好,但是如何在NSURLession中全局地注册NSURLProtocol?
为什么使用URLSession的NSURLProtocol(相同的URL和逻辑与URL一起工作)以及如何获得NSURLProtocol与URLSession一起工作?
请帮助我,让我知道如果你想的更多细节。
