-Headers：術語“-Headers”不被識別為cmdlet的名稱，-Azure函式在cmd提示符下運行并呼叫Web請求

提前感謝您的支持和幫助！

我在VS Code 中有一個Azure 函式（堆疊：.Net - HttpTrigger 模板），代碼如下：

public static class OnPaymentReceived
    {
        [FunctionName("OnPaymentReceived")]
        public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "post", Route = null)] HttpRequest req,
            ILogger log)
        {
            log.LogInformation("Received a payment.");

            string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
            dynamic data = JsonConvert.DeserializeObject(requestBody);
           
            return new OkObjectResult($"Thank you for your purchase");
        }
    }

我知道我們可以IWR通過多種方式運行 Azure 函式，我通過 Windows PowerShell 使用以下 cmdlet：

iwr -Method POST `
-Uri http://localhost:7071/api/OnPaymentReceived
-Headers @{"Content-Type"="application/json"}`
-Body '{}'

我得到了成功的輸出，但與 cmdlet 的第 3 行相關的錯誤是：

輸出：

StatusCode        : 200
StatusDescription : OK
Content           : Thank you for your purchase
RawContent        : HTTP/1.1 200 OK
                    Transfer-Encoding: chunked
                    Content-Type: text/plain; charset=utf-8
                    Date: Fri, 24 Dec 2021 01:10:33 GMT
                    Server: Kestrel

                    Thank you for your purchase
Forms             : {}
Headers           : {[Transfer-Encoding, chunked], [Content-Type, text/plain; charset=utf-8], [Date, Fri, 24 Dec 2021
                    01:10:33 GMT], [Server, Kestrel]}
Images            : {}
InputFields       : {}
Links             : {}
ParsedHtml        : mshtml.HTMLDocumentClass
RawContentLength  : 27

例外： 當我使用第三個 cmdlet 的語法時：-Headers @{"Content-Type"="application/json"}

-Headers : The term '-Headers' is not recognized as the name of a cmdlet, function, script file, or operable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:3 char:1
  -Headers @{"Content-Type"="application/json"}`
  ~~~~~~~~
      CategoryInfo          : ObjectNotFound: (-Headers:String) [], CommandNotFoundException
      FullyQualifiedErrorId : CommandNotFoundException

當我使用第三個 cmdlet 的另一種語法時，例如： header('Content-type: application/json');

header : The term 'header' is not recognized as the name of a cmdlet, function, script file, or operable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:3 char:1
  header('Content-type: application/json');
  ~~~~~~
      CategoryInfo          : ObjectNotFound: (header:String) [], CommandNotFoundException
      FullyQualifiedErrorId : CommandNotFoundException

-Body : The term '-Body' is not recognized as the name of a cmdlet, function, script file, or operable program. Check
the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:4 char:1
  -Body '{}'
  ~~~~~
      CategoryInfo          : ObjectNotFound: (-Body:String) [], CommandNotFoundException
      FullyQualifiedErrorId : CommandNotFoundException

如何解決此例外（此 -Headers cmdlet 的正確語法是什么）？

uj5u.com熱心網友回復：

-Headers ：術語“-Headers”不被識別為 cmdlet、函式、腳本檔案或可運行程式的名稱。

該錯誤是由 cmdlet 中的語法錯誤引起的。

iwr -Method POST `
-Uri http://localhost:7071/api/OnPaymentReceived `
-headers @{"Content-Type"="application/json"} `
-Body '{} '

在每一行命令之后必須有一個空格和撇號符號，如下面的格式 (-cmdlet cmdends ` )。

我已經嘗試過上面的 cmdlet ，你可以看到沒有任何錯誤的輸出。
