我试图在iOS 6教程:第1/2部分中运行Apple推送通知服务中的Ray Wenderlich教程.
我在本地目录中创建了AppID和SSL证书以及密钥和PEM文件.之后,我到了测试证书是否有效的步骤,我从这个本地目录调用了以下命令:
$ openssl s_client -connect gateway.sandbox.push.apple.com:2195
-cert PushChatCert.pem -key PushChatKey.pem
这产生了很多输出.在输出的中间是以下内容:
verify error:num=20:unable to get local issuer certificate
verify return:0
这是一个错误,还是一个错误的测试？如果是错误,原因是什么或者您建议解决什么？
这是完整的输出(减去证书数据):
Enter pass phrase for PushChatKey.pem:
CONNECTED(00000003)
