ASP.NET Identity 2集成到MVC5项目--笔记01 ASP.NET Identity 2集成到MVC5项目--笔记02 继上一篇,本篇主要是实现邮件.用户名登陆和登陆前邮件认证. 1. 登陆之前 到现在为止现在,涉及到身份认证的解决方案大致完成了.需要我们在Identity2Study项目下面按照运行前面的Nuget命令.下面才是真正的用到项目中去.我们演示一个简单的登录. 在我们建立登录控制器之前,我们需要为项目添加一个Startup类和简单配置一下web.config文件.

对于刚从Oracle转向MySql的人都会为,MySql中没有Oracle里的Sequence而感到困惑.MySql中没有了Sequence,那么MySql的主键用什么方式来实现最好呢? 主要有下面几种方式: 1.自增字段作为主键. [推荐方案] MySql尽管比Oracle少了Sequence,可是多了字段的自增长特性. 插入完了以后能够通过运行[SELECT @@IDENTITY]获取上一条插入语句中生成的自增长字段的值. 这个语句非常特别,没有关联到特定的SQL语句,会 让人感觉迷糊,他究

前言 在 ASP.NET Core 中,仍然沿用了 ASP.NET里面的 Identity 组件库,负责对用户的身份进行认证,总体来说的话,没有MVC 5 里面那么复杂,因为在MVC 5里面引入了OWIN的东西,所以很多初学者在学习来很费劲,对于 Identity 都是一头雾水,包括我也是,曾经在学 identity 这个东西前后花了一个多月来搞懂里面的原理.所以大部分开发者对于 Identity 并没有爱,也并没有使用它,会觉得被绑架. 值得庆幸的是,在 ASP.NET Core 中,由于对模
