[iOS] 不合法的伺服器憑證問題
這是個很奇妙的議題，明明是用去年人家寫的案子呼叫API的程式碼，連第三方套件也一模一樣，所帶入的方法和參數一模一樣，但是卻跑不出相同的結果⋯⋯
不知怎麼命名這篇文章，暫且以不合法的伺服器憑證問題為名吧！似乎跟http和https有關聯？還有什麼SSL？
然後就跑出這幾行訊息：
The certificate for this server is invalid. You might be connecting to a server that is pretending to be “xxx.ooo.com.tw” which could put your confidential information at risk.
查了網路前人的解法，原來只要在兩個delegate改成這樣⋯⋯
- (BOOL)connection:(NSURLConnection *)connection
canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace
{
return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
}
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
[challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}
起初還想要請負責server端的人改安全性程度，不過既然去年的project都可以成功跑出結果，還是由我app端來處理問題吧！
寫了以上的code，還是不太明白意義⋯⋯知道的人請跟我說一下＞＜；
