[英]How to code An Azure function to receive data from a web portal?
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");
}
