我正在强制将成员资格提供程序添加到ASP.Net Core应用程序的配置中的问题。我必须添加它,因为它引用了包含旧代码的旧项目,并引用了System.Web.ApplicationServices
的程序集。在此程序集中,流程转到第几行,该行将检查提供程序的名称是否不为空。
if ( providerName == null || SystemWebProxy.Membership.Providers[providerName] == null )
{
throw new ArgumentException(String.Format(CultureInfo.CurrentCulture, ApplicationServicesStrings.Membership_provider_name_invalid), "providerName" );
}
但是无论如何,我在appsettings.json
中添加了必要的实现:
"Membership": {
"DefaultProvider": "blahblah",
"Providers": {
"Add": {
...
"Name": "blahblah"
...
}
}}
在启动类中,我通过以下方式配置sqlMembershipProvider
:
services.Configure<System.Web.Security.SqlMembershipProvider>(Configuration.GetSection("Membership"));
有人可以告诉我,为什么我没有将提供程序实现到配置中吗?也许我走错路了?
答案 0 :(得分:0)
您可以尝试类似的操作:
首先,定义用于处理appsettings.json的类
public class MembershipSettings{
public string DefaultProvider { get; set; }
public Provider Provider { get; set; }
}
public class Provider
{
public string Name { get; set; }
public string ConnectionStringName { get; set; } //not sure if it works
public string ApplicationName { get; set; }
//etc
}
然后从SqlMembershipProvider继承
internal class CustomeSqlMembershipProvider : SqlMembershipProvider
{
public CustomeSqlMembershipProvider(IOptions<MembershipSettings> settings)
{
InitializeProvider(settings.Value);
}
protected virtual void InitializeProvider(MembershipSettings settings)
{
base.Initialize(settings.Provider.Name, PrepareSettings(settings.Provider));
}
private NameValueCollection PrepareSettings(Provider provider) => new NameValueCollection
{
//you can use reflection to do that as well
{ nameof(provider.ApplicationName), provider.ApplicationName},
{nameof(provider.ConnectionStringName), provider.ConnectionStringName}
//...
//etc
};
}
然后在Startup.cs中添加以下行:
services.Configure<MembershipSettings>(Configuration.GetSection("Membership"));
services.AddScoped<SqlMembershipProvider, CustomSqlMembershipProvider>();
最后但并非最不重要的一点是,稍微修改一下appsettings.json(您可以调整MembershiSettings类和CustomSqlMembershiProvider来处理和初始化提供者列表)
"Membership": {
"DefaultProvider": "blahblah",
"Provider": {
...
"Name": "blahblah"
...
}
}
请注意,我对SqlMembershipProvider不太熟悉,因此可能存在一些缺陷。我认为您应该编写自己的MembershipProvider,但如果不能(由于遗留代码),则可以执行上述操作
