Azure 函数应用上的 routePrefix 被忽略

Question

我的函数应用程序似乎忽略了 routePrefix。它在控制台输出中显示正在成功读取配置文件：

info: Host.Startup[0]
      Host configuration file read:
      {
        "version": "2.0",
        "http": {
          "routePrefix": "",
          "maxOutstandingRequests": 20,
          "maxConcurrentRequests": 10,
          "dynamicThrottlesEnabled": false
        }
      }

但是即使它应该是“”，它仍然具有 /api 前缀

Http Functions:
        serverTrigger: http://localhost:7071/api/{*segments}

此外，将 routePrefix 更改为 '/' 或 '/apiprefixtest' 也没有任何区别。

知道为什么 Azure Functions 运行时会忽略 routePrefix 吗？

Answer 1

我看到您使用的是 2.0 版。V2 的架构已更改，因此只需添加“扩展”，如下所示：

{
    "version": "2.0",
        "extensions": {
            "http": {
                "routePrefix": "",
                "maxOutstandingRequests": 20,
                "maxConcurrentRequests": 10,
                "dynamicThrottlesEnabled": false
            }
    }
} 

V2 中有一些重大更改，因此请查看此文档，您可能会发现一些更相关的更改 -

Azure Functions Runtime 2.0.12050-alpha 重大更改通知

这是上面提到的特定于应用程序的文章中的链接 -

所有应用程序级扩展设置现在都位于“扩展”下
