如何识别用于调用Azure函数的HTTP方法(动词)

问题描述

从Azure门户，我们可以轻松创建Function App.一旦创建了功能应用程序，我们就可以向该应用程序添加功能.

From the Azure Portal, we can easily create Function Apps.Once the Function App is created, we can add functions to the app.

就我而言，从自定义模板中，我选择的是C#，API和Webhooks，然后选择通用Webhook C#模板.

In my case, from the custom templates, I'm selecting C#, API & Webhooks, and then selecting the Generic Webhook C# template.

在集成"菜单的" HTTP标题"标题下，有一个下拉框，其中有两个选项:所有方法"和选定方法".然后，我选择 Selected Methods (选择的方法)，然后可以选择该功能可以支持的HTTP方法.我希望我的功能支持GET，PATCH，DELETE，POST和PUT.

From the Integrate menu, under the HTTP Header heading, there is a drop down box to with 2 selections: All Methods and Selected Methods. I then choose Selected Methods, and then have the option to select which HTTP methods the function can support. I would like my function to support GET, PATCH, DELETE, POST and PUT.

在C#run.csx代码中，如何确定使用了哪种方法来调用该方法?我希望能够基于用于调用函数的HTTP方法在函数代码中采取不同的操作.

From within the C# run.csx code, how can I tell what method was used to invoke the method? I would like to be able to take different actions within the function code based on the HTTP method that was used to invoke the function.

这可能吗?

谢谢您的帮助.

推荐答案

回答我自己的问题...您可以检查HttpRequestMessage的Method属性，该属性的类型为HttpMethod.

Answering my own question... you can examine the HttpRequestMessage's Method property, which is of type HttpMethod.

这是MSDN文档:

• HttpRequestMessage MSDN文档

HttpMethod MSDN文档

获取或设置HTTP请求消息使用的HTTP方法.

Gets or sets the HTTP method used by the HTTP request message.

• 命名空间:System.Net.Http
• 组装:System.Net.Http(在System.Net.Http.dll中)

• Namespace: System.Net.Http
• Assembly: System.Net.Http (in System.Net.Http.dll)

和一个快速示例:

#r "Newtonsoft.Json"

using System;
using System.Net;
using Newtonsoft.Json;

public static async Task<object> Run(HttpRequestMessage req, TraceWriter log)
{
    log.Info($"Webhook was triggered!");

    if (req.Method == HttpMethod.Post)
    {
        log.Info($"POST method was used to invoke the function ({req.Method})");
    }
    else if (req.Method == HttpMethod.Get)
    {
        log.Info($"GET method was used to invoke the function ({req.Method})");
    }
    else
    {
        log.Info($"method was ({req.Method})");
    }
}
