如何编写Azure函数以从Web门户接收数据？

Question

如何编写Azure功能以从门户网站（前端）接收数据，如患者姓名，年龄，性别等，并在从前端请求数据时发回数据

使用Visual Studio我创建了Azure函数HTTP触发器

总的想法是使用Azure功能的HttpTrigger，可以通过发布http请求从Web应用程序触发实习生，之后可以在功能端解密。

以下示例显示了一个C＃函数，该函数在查询字符串或HTTP请求正文中查找名称参数。 请注意，返回值用于输出绑定，但不需要返回值属性。

[FunctionName("HttpTriggerCSharp")]
public static async Task<IActionResult> Run(
    [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] 
    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");
}

这是相同的绑定：

{
    "disabled": false,
    "bindings": [
        {
            "authLevel": "function",
            "name": "req",
            "type": "httpTrigger",
            "direction": "in",
            "methods": [
                "get",
                "post"
            ]
        },
        {
            "name": "$return",
            "type": "http",
            "direction": "out"
        }
    ]
}

另外，这是绑定到HttpRequest的C＃脚本代码：

using System.Net;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Primitives;
using 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");
}
