iphone：没有调用 didReceiveAuthenticationChallenge 和 canAuthenticateAgainstProtectionSpace 以获得安全的休息服务

Question

我正在尝试从安全的宁静服务中获取数据。我关注了许多其他帖子以及

How to use NSURLConnection to connect with SSL for an untrusted cert?

但在我的情况下 didReceiveAuthenticationChallenge 和 canAuthenticateAgainstProtectionSpace 没有被调用。

如果您能解决问题，请提供帮助，或者提供一些很好的例子来调用安全的 restful 服务。

 NSURL *url = [NSURL URLWithString:@"https://76.69.53.126:8443/jaxrs/tdgateway/getCountries"];


NSError * error = nil;   
NSMutableURLRequest *urlRequest=[NSMutableURLRequest requestWithURL:url];
[ NSURLConnection sendSynchronousRequest: urlRequest returningResponse: nil error: &error ];

NSLog(@"This is %@",url);




- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace {
    NSLog(@"This is canAuthenticateAgainstProtectionSpace");
    return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
}

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
    NSLog(@"This is didReceiveAuthenticationChallenge");
    [[challenge sender] cancelAuthenticationChallenge:challenge];
}  

Answer 1

它可能与NSURLAuthenticationMethodServerTrust 不同，所以试试这个开始吧：

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace {
    return YES;
}

您不应该立即取消它：

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
    NSLog(@"This is didReceiveAuthenticationChallenge");
    [[challenge sender] cancelAuthenticationChallenge:challenge];
}

NSString *XAPIKEY = @"myapikey";
NSString *LOGINUSER = @"login username";
NSString *LOGINPASS = @"passwords";

// Setup NSURLConnection

        [parts addObject: part];
    }
    return [parts componentsJoinedByString: @"&"];
