IOS:proposalCredentials 和 URLCredential 之间的信任差异

Question

在 URLSession:task:didReceiveChallenge:completionHandler: ，使用.proposedCredential有区别吗？与 URLCredential(trust:)挑战保护空间中的服务器信任对象是什么？

这将作为委托(delegate)方法的完成处理程序中的第二个参数与 .useCredentials 一起传回。 .

Realistically there’s no difference here. For server trust authentication challenges, the system does not actually look at the trust object embedded in the credential you pass to the completion handler; all that matters is that you pass in something.

Having said that, I recommend that you stick on the well-trodden path and construct a new credential. I’m actually quite surprised that proposedCredential is even populated in this case.
