cocoa-touch - 使用 NSURLConnection 忽略证书错误

Question

我收到此错误

The certificate for this server is invalid. You might be connecting to a server
that is pretending to be "server addres goes here" which could put your
confidential information at risk."

我正在使用这个方法:

[NSURLConnection sendSynchronousRequest:request
                      returningResponse:&response
                                  error:&error];

我该如何解决这个问题？

我尝试了这段代码:

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

但是我在 didReceiveResponse 方法中得到了 EXC_BAD_ACCESS。

如果您不发送任何敏感信息，您可以简单地忽略无效证书。 This article描述了如何做到这一点。这是 Alexandre Colucci 的示例实现对于该文章中描述的方法之一。

本质上你想在@implementation之上定义一个虚拟接口(interface):

@interface NSURLRequest (DummyInterface)
+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString*)host;
+ (void)setAllowsAnyHTTPSCertificate:(BOOL)allow forHost:(NSString*)host;
@end

在调用 sendSynchronousRequest 之前，调用您在虚拟接口(interface)中定义的私有(private)方法:

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