Question

下面是运行Azure函数所需的代码。它看起来很长而且凌乱。无论如何，我可以将其缩短吗？我还不熟练C＃。主要问题在于第一个参数。

public static async Task<IActionResult> Run(
    [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
    ILogger log)
{
    // Implementation omitted
}

@ASKYous，

这已经是模板默认随附的重构代码。

public static async Task<IActionResult> Run(
    [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
    ILogger log)
{
    // Implementation omitted
}

只有2个参数：

Httprequest
ILogger

如果不需要授权部分，可以使用以下类似内容：

使用System.Net；使用Microsoft.AspNetCore.Mvc; 使用Microsoft.Extensions.Primitives；使用Newtonsoft.Json;

public static async Task<IActionResult> Run(HttpRequest req, ILogger log)
{
    log.LogInformation("C# HTTP trigger function processed a request.");

    string name = req.Query["name"];

    string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
    dynamic data = JsonConvert.DeserializeObject(requestBody);
    name = name ?? data?.name;

    return name != null
        ? (ActionResult)new OkObjectResult($"Hello, {name}")
        : new BadRequestObjectResult("Please pass a name on the query string or in the request body");
}

还可以绑定到自定义对象，而不是HttpRequest。从请求的主体创建此对象，并将其解析为JSON。同样，可以将类型与200状态代码一起传递给HTTP响应输出绑定并作为响应正文返回。

using System.Net;
using System.Threading.Tasks;
using Microsoft.Extensions.Logging;

public static string Run(Person person, ILogger log)
{   
    return person.Name != null
        ? (ActionResult)new OkObjectResult($"Hello, {person.Name}")
        : new BadRequestObjectResult("Please pass an instance of Person.");
}

public class Person {
     public string Name {get; set;}
}

如何使此代码更短或更清晰？
