使用NSURLConnection忽略证书错误 [英] Ignoring certificate errors with NSURLConnection

问题描述

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."

我使用这种方法：

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

我可以解决这个问题吗？

How can I fix this?

我试过这个代码：

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

那么我在didReceiveResponse方法中获取EXC_BAD_ACCESS。

but then I get EXC_BAD_ACCESS in the didReceiveResponse method.

推荐答案

如果不发送任何敏感信息，您可以忽略无效的证书。 本文介绍了您可以如何做那。以下是 Alexandre Colucci 对所述方法之一的示例实现

You could simply ignore the invalid certificate if you are not sending any sensitive information. This article describes how you could do that. Here is an example implementation by Alexandre Colucci for one of the methods described in that article.

实质上，您要在 @implementation 上方定义一个虚拟接口：

Essentially you want to define a dummy interface just above the @implementation:

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

然后在调用 sendSynchronousRequest ，调用在虚拟接口中定义的私有方法：

And before you call sendSynchronousRequest, invoke the private method you defined in the dummy interface:

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