如何在 ASP.NET 5 MVC 6 (vNext) 中定义 Identity 的密码规则?

问题描述

ASP.NET 5 中提供的默认身份提供程序默认有非常严格的密码规则，需要一个小写字符、一个大写字符、一个非字母数字字符和一个数字.我正在寻找一种方法来更改提供商的密码要求.

The default Identity provider provided in ASP.NET 5 has very strict password rules by default, requiring a lower case character, an upper case character, a non-alphanumeric character, and a number. I am looking for a way to change the password requirements for the provider.

以前在 ASP.NET 4 中，可以通过 Web.config XML 文件配置提供程序，如 以前回答过.但是 ASP.NET 5 使用新的基于代码的配置模式，不清楚如何配置身份.

Previously in ASP.NET 4, the provider could be configured via the Web.config XML file, as previously answered. However ASP.NET 5 uses the new code based configuration pattern and it is unclear how to configure the identity.

推荐答案

我实际上最终弄清楚了这一点，事实证明您需要为 AddDefaultIdentity 提供一个合适的 lambda 表达式来配​​置它提供的 IdentityOptions.这是在 Startup 类的 ConfigureServices 方法中完成的，如下所示:

I actually ended up figuring this out, it turns out you need to supply AddDefaultIdentity with a suitable lambda expression that configures the IdentityOptions it provides. This is done inside the ConfigureServices method within the Startup class, like so:

public class Startup {
    public void ConfigureServices(IServiceCollection services) {

        // Add Identity services to the services container.
        services.AddDefaultIdentity<ApplicationIdentityDbContext, ApplicationUser, IdentityRole>(Configuration,
            o => {
                o.Password.RequireDigit = false;
                o.Password.RequireLowercase = false;
                o.Password.RequireUppercase = false;
                o.Password.RequireNonLetterOrDigit = false;
                o.Password.RequiredLength = 7;
            });
    }
}

beta5 中它略微更改为:

The above was true in the beta1 versions of the framework, in the latest beta5 it has changed slightly to:

services.AddIdentity<ApplicationUser, IdentityRole>(o => {
    // configure identity options
    o.Password.RequireDigit = false;
    o.Password.RequireLowercase = false;
    o.Password.RequireUppercase = false;
    o.Password.RequireNonAlphanumeric = false;
    o.Password.RequiredLength = 6;
})
.AddEntityFrameworkStores<ApplicationIdentityDbContext>()
.AddDefaultTokenProviders();
