Swift 正在重置URLSession.shared凭据

我正在尝试使用URLSession.shared执行一些api请求（使用凭据），但它的行为与预期不符

当用户第一次输入他们的凭据时，我使用以下命令将其设置为会话的默认值

let credential = URLCredential(user: username, password: password, persistence: .forSession)
URLCredentialStorage.shared.setDefaultCredential(credential, for: myProtectionSpace)

然后，我将使用此命令发出第一个url请求。对于本例，假设请求正在尝试访问

这很好用，凭证会被传递，直到我需要用户注销为止。当我存储不同的凭据时，即使密码不正确，对的请求仍然会返回OK，并且似乎不会发出401质询

我尝试了以下所有方法，但似乎没有任何方法可以清除该特定URL的会话凭据

// Attempt #1: doesn't work
URLSession.shared.reset {
     // I confirmed this eliminates all credentials in the URLCredentialStorage.shared
     // store updated credentials and fire off new request here
}

// Attempt #2: doesn't work
URLCredentialStorage.shared.remove(credential, for: myProtectionSpace)
URLSession.shared.invalidateAndCancel()
// store updated credentials and fire off new request here 

// Attempt #3: doesn't work
URLCredentialStorage.shared.remove(credential, for: myProtectionSpace)
URLSession.shared.finishTasksAndInvalidate()
// store updated credentials and fire off new request here

在第一次成功请求后，服务器似乎没有发出401质询，因此没有使用修改后的凭据。我是否因为这个原因而被迫使用自定义URLSession

您是否尝试过使用

URLCredentialStorage.shared.set（credential，for:myProtectionSpace）

而不是setDefault？我也尝试过，同样的结果我发现我必须调用它来“重置”会话，从而重置凭据。

// Attempt #1: doesn't work
URLSession.shared.reset {
     // I confirmed this eliminates all credentials in the URLCredentialStorage.shared
     // store updated credentials and fire off new request here
}

// Attempt #2: doesn't work
URLCredentialStorage.shared.remove(credential, for: myProtectionSpace)
URLSession.shared.invalidateAndCancel()
// store updated credentials and fire off new request here 

// Attempt #3: doesn't work
URLCredentialStorage.shared.remove(credential, for: myProtectionSpace)
URLSession.shared.finishTasksAndInvalidate()
// store updated credentials and fire off new request here
