OAuth2 webapp在.Net CORE中实现GitHub webhooks

Question

我正在尝试构建一个实现GitHub webhooks的OAuth2 Web应用程序。

这似乎只能使用AspNetCore 2.1。

要在我的项目中实现webhooks，我首先必须将services.AddMvc()中的startup.cs重新配置为services.AddMvcCore().AddGitHubWebHooks()

这会产生错误，因为MvcCore()未配置为使用Razor Pages。

如果我想使用现有的脚手架MVC结构，我该如何解决这个问题？

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvcCore()
            .AddViews()
            .AddRazorViewEngine()
            .AddGitHubWebHooks();
    }
}

StartUp.cs包含更多代码，如有必要，我可以发布它

错误：

Answer 1

如果你看看code for AddMvc()，你可以看到它是如何添加Razor Pages支持的。特别是这段代码：

// Default framework order
builder.AddFormatterMappings();
builder.AddViews();
builder.AddRazorViewEngine();
builder.AddRazorPages();
builder.AddCacheTagHelper();

也就是说，AddMvcCore()概念性地是AddMvc()的一个子集。鉴于Microsoft.AspNetCore.WebHooks项目包含IMvcBuilder和IMvcCoreBuilder扩展（又名AddMvc和AddMvcCore），您只需要换掉你的方法：

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services
            .AddMvc()
            .AddGitHubWebHooks();
    }
}
