如何在Azure Functions中使用HttpTrigger进行ModelBinding？

Question

我需要创建一个响应HTTP POST的Azure功能,并利用集成的模型绑定.

我该怎么修改呢

    [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);
    }

以这种方式,我的客户端POST的对象,我有正常的ASP.NET样式模型绑定？

Answer 1

HttpRequestMessage您可以使用自定义类型，而不是使用参数。绑定将尝试将请求正文解析为 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

根据代码中HTTP触发器的文档，您可以简单地接受自己的对象：

对于自定义类型（例如POCO），Functions将尝试将请求正文解析为JSON，以填充对象属性。

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);
}
