V5.2.2具有以下code：

V5.2.2 has the following code:

public HelpController()
        : this(GlobalConfiguration.Configuration)
    {
    }

    public HelpController(HttpConfiguration config)
    {
        Configuration = config;
    }

在HelpController

in the HelpController

统一使用最参数的构造函数，所以要得到它的使用参数的构造函数，我改变了第二个重载受保护的：

Unity uses the constructor with the most arguments, so to get it to use the parameterless constructor I changed the second overload to protected:

    protected HelpController(HttpConfiguration config)
    {
        Configuration = config;
    }
