ios - NSURLErrorDomain Code=-1202 使用同步请求时

Question

我尝试发送同步请求并收到以下错误。

Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be “xx.xxxx.com” which could put your confidential information at risk."

请在下面找到代码

    NSURL *url=[[NSURL alloc]initWithString:strURL];
        NSMutableURLRequest *request=[[NSMutableURLRequest alloc]initWithURL:url];
        [url release];
        [request setTimeoutInterval:90];
        [request setHTTPMethod:@"POST"];
        [request setHTTPBody:dataForChallenge];
        [request setValue:@"application/json" forHTTPHeaderField:@"content-type"];
        [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];

        NSURLResponse *resp = nil;
        NSError *err = nil;
        NSData *response = [NSURLConnection sendSynchronousRequest: request returningResponse: &resp error: &err];


    - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
    //    NSLog(@"selector : %@",NSStringFromSelector(_cmd));
    if([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
    {
        //      NSLog(@"selector 1: %@",NSStringFromSelector(_cmd));
        [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
    }
    [challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}
- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace
{
    //    NSLog(@"selector : %@",NSStringFromSelector(_cmd));    
    if( [[protectionSpace authenticationMethod] isEqualToString:NSURLAuthenticationMethodServerTrust] )
    {
        //      NSLog(@"selector 1: %@",NSStringFromSelector(_cmd));    
        return YES;
    }
    return NO;
}

以上两种方法都没有被调用，在我的例子中，我必须只发送同步请求。

我使用了下面这行，它工作正常，但 AppStore 拒绝了我的应用程序:

    [NSURLRequest setAllowsAnyHTTPSCertificate:YES forHost:[url host]];

我该如何解决这个问题？

Answer 1

要么使用 NSURLConnection 方法的异步版本(允许您指定委托(delegate))，要么使用 trick like this像处理同步调用一样处理异步调用。

编辑:

关于使用 NSURLConnection 的异步版本，我的意思是:

self.connection = [[NSURLConnection alloc] initWithRequest:request
                                 delegate:self];

(你需要有一个 NSURLConnection* strong property)。
