I'm use host to request https://MyHost/ the networkProtocolName return "h3"
assumesHTTP3Capable = YES
- (void)URLSession:(NSURLSession *)session
task:(NSURLSessionTask *)task
didFinishCollectingMetrics:(NSURLSessionTaskMetrics *)metrics AF_API_AVAILABLE(ios(10), macosx(10.12), watchos(3), tvos(10))
{
for (NSURLSessionTaskTransactionMetrics * m in metrics.transactionMetrics){
if(m.networkProtocolName.length > 0){
NSLog(@"networkProtocolName %@", m.networkProtocolName);
break;
}
}
}
but when I use ip replace MyHost to request, and add MyHost to http header @{@"host": "ip"}, the networkProtocolName return "h2"
- (void)URLSession:(NSURLSession *)session
task:(NSURLSessionTask *)task
didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge
completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler
{
NSURLSessionAuthChallengeDisposition disposition = NSURLSessionAuthChallengePerformDefaultHandling;
NSURLCredential *credential = nil;
//get header host replace ip
NSString *host = [[task.currentRequest allHTTPHeaderFields] objectForKey:@"host"];
if (!host) {
host = task.currentRequest.URL.host;
}
if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) {
if ([weak evaluateServerTrust:challenge.protectionSpace.serverTrust forDomain:host]) {
disposition = NSURLSessionAuthChallengeUseCredential;
credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];
} else {
disposition = NSURLSessionAuthChallengePerformDefaultHandling;
}
} else {
disposition = NSURLSessionAuthChallengePerformDefaultHandling;
}
// 对于其他的 challenges 直接使用默认的验证方案
completionHandler(disposition,credential);
}
-(BOOL)evaluateServerTrust:(SecTrustRef)serverTrust forDomain:(NSString *)domain {
//创建证书校验策略
NSMutableArray *policies = [NSMutableArray array];
if (domain) {
[policies addObject:(__bridge_transfer id)SecPolicyCreateSSL(true, (__bridge CFStringRef)domain)];
} else {
[policies addObject:(__bridge_transfer id)SecPolicyCreateBasicX509()];
}
//绑定校验策略到服务端的证书上
SecTrustSetPolicies(serverTrust, (__bridge CFArrayRef)policies);
//评估当前 serverTrust 是否可信任，
//官方建议在 result = kSecTrustResultUnspecified 或 kSecTrustResultProceed 的情况下 serverTrust 可以被验证通过，
//https://developer.apple.com/library/ios/technotes/tn2232/_index.html
//关于SecTrustResultType的详细信息请参考SecTrust.h
SecTrustResultType result;
SecTrustEvaluate(serverTrust, &result);
return (result == kSecTrustResultUnspecified || result == kSecTrustResultProceed);
}
https://ip/ networkProtocolName return "h2"
does ip request do not supprt HTTP/3?
hope to respone thank you.
