我有以下简单的代码来连接到 SSL 网页

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

如果证书是自签名证书则会出错Error Domain=NSURLErrorDomain Code=-1202 UserInfo=0xd29930 "untrusted server certificate"。 有没有办法将其设置为接受连接无论如何(就像在浏览器中可以按接受一样)或绕过它的方法？

最佳答案

有一个支持的 API 可以实现这一点!将这样的内容添加到您的 NSURLConnection 委托(delegate)中:

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

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
  if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
    if ([trustedHosts containsObject:challenge.protectionSpace.host])
      [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];

  [challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}

请注意，connection:didReceiveAuthenticationChallenge: 可以稍后将其消息发送给challenge.sender(很多)，在必要时向用户显示对话框等之后。
