c# - 如何在 Azure Functions 中使用 Http 触发器进行模型绑定(bind)？

Question

我需要创建一个响应 HTTP POST 并利用集成模型绑定(bind)的 Azure 函数。

如何修改这个

    [FunctionName("TokenPolicy")]
    public static HttpResponseMessage Run([HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = "TokenPolicy/{IssuerID}/{SpecificationID}")]HttpRequestMessage req, string IssuerID, string specificationID, TraceWriter log)
    {
        log.Info("C# HTTP trigger function processed a request. TokenPolicy");

        // Fetching the name from the path parameter in the request URL
        return req.CreateResponse(HttpStatusCode.OK, "data " +  specificationID);
    }

以这样的方式，我的客户端 POST 是对象，并且我有正常的 ASP.NET 样式模型绑定(bind)？

基于 HTTP trigger from code 的文档，你可以简单地接受你自己的对象:

For a custom type (such as a POCO), Functions will attempt to parsethe request body as JSON to populate the object properties.

public class MyModel
{
    public int Id { get; set; }
    public string Name { get; set; }
}

[FunctionName("TokenPolicy")]
public static HttpResponseMessage Run([HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = "TokenPolicy/{IssuerID}/{SpecificationID}")]MyModel myObj, string IssuerID, string specificationID, TraceWriter log)
{
    log.Info("C# HTTP trigger function processed a request. TokenPolicy");


    // Do something your your object

    return new HttpResponseMessage(HttpStatusCode.OK);
}
