.net core2.0下使用Identity改用dapper存储数据(实例讲解)

前言、

已经好多天没写博客了，鉴于空闲无聊之时又兴起想写写博客，也当是给自己做个笔记。过了这么些天，我的文笔还是依然那么烂就请多多谅解了。今天主要是分享一下在使用.netcore2.0下的实际遇到的情况。在使用webapi时用了identity做用户验证。官方文档是的是用EF存储数据来使用dapper，因为个人偏好原因所以不想用EF。于是乎就去折腾。改成使用dapper做数据存储。于是就有了以下的经验。

一、使用Identity服务

先找到Startup.cs这个类文件找到ConfigureServices方法

services.AddIdentity().AddDefaultTokenProviders();//添加Identity
services.AddTransient,CustomUserStore>();
services.AddTransient,CustomRoleStore>();
stringconnectionString=Configuration.GetConnectionString("SqlConnectionStr");
services.AddTransient(e=>newSqlConnection(connectionString));
services.AddTransient();

然后在Configure方法的app.UseMvc()前加入下列代码，netcore1.0的时候是app.UseIdentity()现在已经弃用改为以下方法。

//使用验证
app.UseAuthentication();

这里的ApplicationUser是自定义的一个用户模型具体是继承IdentityUser继承它的一些属性

publicclassApplicationUser:IdentityUser
{
publicstringAuthenticationType{get;set;}
publicboolIsAuthenticated{get;set;}
publicstringName{get;set;}
}

这里的CustomUserStore是自定义提供用户的所有数据操作的方法的类它需要继承三个接口：IUserStore，IUserPasswordStore，IUserEmailStore

IUserStore接口是在用户存储中必须实现的唯一接口。它定义了用于创建、更新、删除和检索用户的方法。

IUserPasswordStore接口定义实现以保持经过哈希处理的密码的方法。它包含用于获取和设置工作经过哈希处理的密码，以及用于指示用户是否已设置密码的方法的方法。

IUserEmailStore接口定义实现以存储用户电子邮件地址的方法。它包含用于获取和设置的电子邮件地址和是否确认电子邮件的方法。

这里跟.netcore1.0的实现接口方式有点不同。需要多实现IUserEmailStore才能不报错

具体代码如下。以供大家参考。
