如何在 Azure Functions 中使用 Http 触发器进行模型绑定？

Question

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

我该如何修改这个

    [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);
    }

我的客户 POST 是对象，而我有正常的 ASP.NET 样式模型绑定？

Answer 1

您可以使用自定义类型来代替 HttpRequestMessage 参数。绑定将尝试将请求主体解析为 JSON 并在调用函数之前填充该对象。这里有一些细节：https://docs.microsoft.com/azure/azure-functions/functions-bindings-http-webhook-trigger?tabs=csharp#payload

Answer 2

根据 HTTP trigger from code 的文档，您可以简单地接受您自己的对象：

For a custom type (such as a POCO), Functions will attempt to parse the 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);
}
