azure v4 无服务器函数如何在根上返回响应？

Question

c# odata 无服务器函数（隔离模型）需要在根返回一个清单。我在 host.json 文件中将 api 前缀替换为“”，但是当我尝试 Route="" 时，应用程序在根目录返回标准的“您的应用程序已准备就绪”响应。我怎样才能覆盖这种行为？

Answer 1

您可以使用

Route="{ignored:maxlength(0)?}"

在根端点返回响应。

感谢您的见解bredd。

我创建了一个 C# OData 隔离的 Azure 函数，并且能够在根上返回响应。

函数.cs：

[Function("GetProducts")]
public async Task<HttpResponseData> GetProducts([HttpTrigger(AuthorizationLevel.Function, "get","post", Route = "{ignored:maxlength(0)?}")] HttpRequestData req, string ignored = "")
{

var response = req.CreateResponse(HttpStatusCode.OK);
    var manifest = new
    {
        name = "My OData Service",
        version = "1.0.0",
        description = "This is the manifest for my OData service."
    };

    await response.WriteAsJsonAsync(manifest);
    return response;
}

程序.cs：

var host = new HostBuilder()
    .ConfigureFunctionsWebApplication()
   .ConfigureFunctionsWorkerDefaults()
    .ConfigureServices(services =>
    {
        services.AddControllers()
            .AddOData(options => options.Select()
       .Filter()
       .OrderBy()
       .Count()
       .Expand()
       .SetMaxTop(100)
       .AddRouteComponents("odata", GetEdmModel()));
    })
    .Build();

host.Run();
IEdmModel GetEdmModel()
{
    var builder = new ODataConventionModelBuilder();
    builder.EntitySet<Products>("Products");
    return builder.GetEdmModel();
}

主机.json：

 "extensions": {
   "http": {
     "routePrefix": ""
   }
 }

控制台输出：

Functions:

        GetProducts: [GET,POST] http://localhost:7220/{ignored:maxlength(0)?}

For detailed output, run func with --verbose flag.
