在使用文字识别时，在ios10.0以下的系统，运行demo是可以进行扫描，但是在10.3.1上使用时出现以下错误：

Error Domain=com.baidu.aipocr Code=283504 "Fail to connect to authentication server(The certificate for this server is invalid. You might be connecting to a server that is pretending to be “verify.baidubce.com” which could put your confidential information at risk.)" UserInfo={NSLocalizedDescription=Fail to connect to authentication server(The certificate for this server is invalid. You might be connecting to a server that is pretending to be “verify.baidubce.com” which could put your confidential information at risk.)}

请问在10.3.1上，怎么解决证书验证？
