我使用Npgsql 2.1和EntityFramework 6.0来使用PostgreSQL（Code First）。 一切正常。这是我的Web.config的一部分：
<configuration>
<configSections>
//---
<connectionStrings>
<add name="MovieDBContext" connectionString="Server=127.0.0.1;Port=5432;Database=postgres;User Id=postgres;Password=123;"
providerName="Npgsql" />
</connectionStrings>
//---
<entityFramework>
<defaultConnectionFactory type="Npgsql.NpgsqlFactory, Npgsql" />
<providers>
<provider invariantName="Npgsql" type="Npgsql.NpgsqlServices, Npgsql.EntityFramework"></provider>
</providers>
</entityFramework>
<system.data>
<DbProviderFactories>
<remove invariant="Npgsql" />
<add name="Npgsql Data Provider" invariant="Npgsql" support="FF" description=".Net Framework Data Provider for Postgresql"
type="Npgsql.NpgsqlFactory, Npgsql" />
</DbProviderFactories>
</system.data>
</configuration>
一切正常，10个相关表格。但现在我需要授权。
我当然读了这篇文章 PostgreSQL + Npgsql connector + MVC and SimpleMembership Not working Francisco Junior建议使用Daniel Nauck的AspSQLProvider。
我从NuGet安装了NauckIT.PostgreSQLProvider.2.0.0。 从包中执行脚本以为其创建表集。 将此部分配置信息添加到Web.config：
<system.web>
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" />
<authentication mode="Forms">
<forms loginUrl="~/Account/Login" timeout="2880" />
</authentication>
<machineKey validationKey="518A9D0E650ACE4CB22A35DA4563315098A96D0BB8E357531C7065D032099214A11D1CA074B6D66FF0836B35CEAAD0E7EEEFAED772754832E0A5F94EF8522222"
decryptionKey="DB5660C109E9EC70F044BA1FED99DE0C5922321C5125E84C23A1B5CA0E426909"
validation="SHA1" decryption="AES" />
<membership defaultProvider="PgMembershipProvider">
<providers>
<clear/>
<add name="PgMembershipProvider" type="NauckIT.PostgreSQLProvider.PgMembershipProvider" connectionStringName="MovieDBContext" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="true" passwordFormat="Hashed" applicationName="MvcMovie"/>
</providers>
</membership>
<roleManager enabled="true" defaultProvider="PgRoleProvider" cacheRolesInCookie="true" cookieName=".AspNetRoles" cookiePath="/" cookieProtection="All" cookieRequireSSL="false" cookieSlidingExpiration="true" createPersistentCookie="false" cookieTimeout="30" maxCachedResults="25">
<providers>

<add name="PgRoleProvider" type="NauckIT.PostgreSQLProvider.PgRoleProvider" connectionStringName="MovieDBContext" applicationName="MvcMovie"/>
</providers>
</roleManager>
<profile enabled="true" defaultProvider="PgProfileProvider">
<providers>
<clear/>
<add name="PgProfileProvider" type="NauckIT.PostgreSQLProvider.PgProfileProvider" connectionStringName="MovieDBContext" applicationName="MvcMovie"/>
</providers>
<properties>
<add name="FirstName"/>
<add name="LastName"/>
</properties>
</profile>
<sessionState mode="Custom" customProvider="PgSessionStateStoreProvider">
<providers>
<clear/>
<add name="PgSessionStateStoreProvider" type="NauckIT.PostgreSQLProvider.PgSessionStateStoreProvider" enableExpiredSessionAutoDeletion="true" expiredSessionAutoDeletionInterval="60000" enableSessionExpireCallback="false" connectionStringName="MovieDBContext" applicationName="MvcMovie" />
</providers>
</sessionState>
尝试运行时出错：
Parser Error Message: This method cannot be called during the application's pre-start initialization phase.
Source Error:
<providers>
<clear/>
<add name="PgMembershipProvider" type="NauckIT.PostgreSQLProvider.PgMembershipProvider" connectionStringName="MovieDBContext" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="true" passwordFormat="Hashed" applicationName="MvcMovie"/>
</providers>
</membership>
试图找到有关此错误的任何内容。 遵循此建议 asp.net 4.5 custom membership provider configuration throws strange exception 我将其添加到Web.config
<appSettings>
//---
<add key="enableSimpleMembership" value="false"/>
<add key="autoFormsAuthentication" value="false"/>
现在应用程序可以运行，因为SimpleMembership已被禁用。 顺便说一句，尝试注册用户我得到下一个错误

在班级
InitializeSimpleMembershipAttribute
请帮助配置Daniel Nauck的AspSQLProvider和InitializeSimpleMembershipAttribute（如果需要）。
谢谢！
答案 0 :(得分：3)
问题在于实现AccountController而不是默认。
确定。这是解决方案
我喜欢PostgreSQL的会员和角色提供者 https://code.google.com/p/pgprovider/ 因为它在启动时自己创建所有必要的表））
安装它：
Install-Package pgProvider
添加到Web.config：
<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>
<connectionStrings>
<add name="MovieDBContext" connectionString="Server=127.0.0.1;Port=5432;Database=postgres;User Id=postgres;Password=000;" providerName="Npgsql" />
<add name="pgProvider" connectionString="Server=127.0.0.1;Port=5432;Database=postgres;User Id=postgres;Password=000;" providerName="Npgsql" />
</connectionStrings>
<membership defaultProvider="pgMembershipProvider">
<providers>
<clear />
<add name="pgMembershipProvider" type="pgProvider.pgMembershipProvider, pgProvider" applicationName="MvcMovie"/>
</providers>
</membership>
<roleManager defaultProvider="pgRoleProvider">
<providers>
<clear />
<add name="pgRoleProvider" type="pgProvider.pgRoleProvider, pgProvider" applicationName="MvcMovie"/>
</providers>
</roleManager>
然后添加到Web.config：
<appSettings>
//---
<add key="enableSimpleMembership" value="false"/>
<add key="autoFormsAuthentication" value="false"/>
</appSettings>
然后删除默认创建的AccountController。
最后添加AccountController：
public class AccountController : Controller
{
public ActionResult Login(string returnUrl)
{
ViewBag.ReturnUrl = returnUrl;
return View();
}
[HttpPost]
public ActionResult Login(LoginModel model, string returnUrl)
{
if (ModelState.IsValid)
{
if (Membership.ValidateUser(model.UserName, model.Password))
{
FormsAuthentication.SetAuthCookie(model.UserName, model.RememberMe);
if (Url.IsLocalUrl(returnUrl))
{
return Redirect(returnUrl);
}
else
{
return RedirectToAction("Index", "Home");
}
}
else
{
ModelState.AddModelError("", "The user name or password provided is incorrect.");
}
}
return View(model);
}
public ActionResult LogOff()
{
FormsAuthentication.SignOut();
return RedirectToAction("Login", "Account");
}
public ActionResult Register()
{
return View();
}
[HttpPost]
public ActionResult Register(RegisterModel model)
{
if (ModelState.IsValid)
{
MembershipCreateStatus status;
MembershipUser membershipUser = (Membership.Provider).CreateUser(
model.UserName, model.Password, null,null,null, true, null, out status);
if (membershipUser != null)
{
FormsAuthentication.SetAuthCookie(model.UserName, false);
return RedirectToAction("Index", "Home");
}
else
{
ModelState.AddModelError("", "Registration error");
}
}
return View(model);
}
}
提供商的源代码在这里： https://code.google.com/p/pgprovider/source/browse/trunk/pgProvider/pgMembershipProvider.cs
就是这样。
它适用于默认创建的登录和注册视图。
