在 .Net CORE 中实现 GitHub webhooks 的 OAuth2 webapp答案

【问题标题】：OAuth2 webapp implementing GitHub webhooks, in .Net CORE在 .Net CORE 中实现 GitHub webhooks 的 OAuth2 webapp
【发布时间】：2018-08-13 09:27:54
【问题描述】：

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

这似乎只有使用AspNetCore 2.1 才能实现。

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

这会产生错误，因为 MvcCore() 未配置为使用 Razor 页面。

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，如果需要，我可以发布它

错误：

@chuex Okej，感谢您的评论。相应地更新了线程。
我真的没有答案，但是在注册 Serilog 后构建我的 Autofac 容器时，我在 Asp.Net Core Webhooks 预览中遇到了同样的错误。删除 Serilog 会删除错误。我使用的所有其他服务似乎都可以在 Asp .Net Core Webhook 预览中正常工作 - 只是 Serliog 导致 System.TypeLoadException：无法加载类型“Microsoft.AspNetCore.Mvc.Internal.IHttpResponseStreamWriterFactory”错误。也许看看你的 startup.cs 中的其他代码有什么不满意的地方。

【解决方案1】：

如果您查看code for AddMvc()，您会看到它是如何添加 Razor Pages 支持的。具体这段代码：

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

也就是说，AddMvcCore() 在概念上是AddMvc() 的子集。鉴于Microsoft.AspNetCore.WebHooks 项目同时包含IMvcBuilder 和IMvcCoreBuilder 扩展（又名AddMvc 和AddMvcCore），您应该只需要更换您的方法：

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