- 5. services.AddMvc()">5. services.AddMvc()
- 6. 差不多明白了区别,看一看源码吧:
1. services.AddMvcCore()
只注册路由请求和执行控制器所必要的核心服务,确保 Pipeline 程序可运转。除非是有能力并想完全去自主DIY,一般不建议直接使用这个。2. services.AddControllers()
除包含了 AddMvcCore() 所有功能,再加上:- Authorization
- ApiExplorer
- Data Annotation
- Formatter Mapping
- CORS
3. services.AddRazorPages()
包含 AddMvcCore() 所有功能,再加上:- Razor Pages
- Authorization
- Data Annotation
- Cache Tag Helper
4. services.AddControllersWithViews()
包含 AddControllers() 所有功能,再加上:- cshtml和Razor View
- Cache Tag Helper
5. services.AddMvc()
包含 AddControllersWithViews() 及 AddRazorPages() 功能。 包含的功能最为齐全,如果不想遗漏功能,直接使用这个就行。 一张图应该能准确的概括上面一堆文字叙述:6. 差不多明白了区别,看一看源码吧:
