ios - 以 UTF-8 格式转换响应时出现问题

Question

我收到此行的错误:

Data(from: responseValue.utf8 as! Decoder)

)

Cannot convert value of type 'Data' to expected argument type 'Data'

do{
    let responseData = try JSONDecoder().decode(forget_Base.self, from: Data(from: responseValue.utf8 as! Decoder))
    if responseData.code == 200
    {
        let message = isNilValue(assignValue: responseData.message)
        let alert = UIAlertController(title: "", message: message, preferredStyle: .alert)
        let action = UIAlertAction(title: "OK", style: .default, handler: {(_action) -> Void in
            let next = self.storyboard?.instantiateViewController(withIdentifier: "SetPasswordVCSID")
            self.navigationController?.pushViewController(next!, animated: true)
        })
        alert.addAction(action)
        self.present(alert, animated: true, completion: nil)
    }
    else
    {
    }
}
catch
{
    print("error")
}

我该如何解决？我已经尝试了太多东西，但我坚持不懈。

根据报错信息，很简单

let responseData = try JSONDecoder().decode(forget_Base.self, from: Data(responseValue.utf8))

转换为 Decoder 的类型无论如何都是毫无意义的。

并且请遵守命名约定，forget_Base 太可怕了，将其命名为ForgetBase
