如何編寫Azure函數以從Web門戶接收數據？

Question

如何編寫Azure功能以從門戶網站（前端）接收數據，如患者姓名，年齡，性別等，並在從前端請求數據時發回數據

使用Visual Studio我創建了Azure函數HTTP觸發器

Answer 1

總的想法是使用Azure功能的HttpTrigger，可以通過發布http請求從Web應用程序觸發實習生，之后可以在功能端解密。

以下示例顯示了一個C＃函數，該函數在查詢字符串或HTTP請求正文中查找名稱參數。 請注意，返回值用於輸出綁定，但不需要返回值屬性。

[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");
}

這是相同的綁定：

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

另外，這是綁定到HttpRequest的C＃腳本代碼：

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");
}
