前段时间开发公司项目遇到了https信任问题，请求之后报了以下错误：
The certificate for this server is invalid. You might be connecting to a server that is pretending to be “xxx” which could put your confidential information at risk.
解决之后在此记录一下，本人用swift开发，请求库用的是Alamofire，只需在Alamofire请求之前写上一段代码即可

Alamofire.SessionManager.default.delegate.sessionDidReceiveChallenge = { session,challenge in
            return  (URLSession.AuthChallengeDisposition.useCredential,URLCredential(trust:challenge.protectionSpace.serverTrust!))
        }
Alamofire.request(encodedURLString, method: method, parameters: para, headers: headers).responseJSON{ (response) in
            switch response.result{
            case .success:
               
                }
            case .failure(let error):
                
            }
        }

运行之后发现解决了
