我正在尝试实现一个Azure函数，它将ID作为输入并根据该ID检索数据。基本上，Azure函数将调用另一个API，并从中获取数据。我面临着无法将ID作为参数传递的问题。
应用编程接口（. NET）

[HttpGet]
        [Route("{id:guid}")]
        public async Task<IActionResult> GetContact([FromRoute] Guid id)
        {
            var contact = await dbContext.Contacts.FindAsync(id);

            if (contact == null)
            {
                return NotFound();
            }

            return Ok(contact);
        }

• • 功能**

[FunctionName("GetSingleContact")]
        public async Task<IActionResult> GetContact(
            [HttpTrigger(AuthorizationLevel.Anonymous, nameof(HttpMethods.Get), Route = null)] HttpRequest req,
            ILogger log)
        {
            try
            {

                var client = _httpClientFactory.CreateClient();
                string id = req.Query["id"];//Null
                string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
                dynamic data = JsonConvert.DeserializeObject(requestBody);
                id ??= data?.id;

                HttpResponseMessage httpResponseMessage = await client.GetAsync($"https://localhost:7209/api/Contacts/{id}");

                if (httpResponseMessage.StatusCode == System.Net.HttpStatusCode.OK)
                {
                    var content = httpResponseMessage.Content;
                    var data1 = await content.ReadAsStringAsync();
                    return new OkObjectResult(data1);
                }

            }
            catch(Exception ex)
            {
                return new BadRequestObjectResult(ex.Message);
            }
            
            return new BadRequestObjectResult("Problem");
        }

每次我传递ID时它都是空的。这是怎么回事？
