  .net core mvc update call API with httpclientfactory

  Dec 27, 2020 03:35 PM|ExceedingLife|LINK

  Hello all

  I have been able to call my api with Create, Get, GetAll, and Delete. But I am having troubles with only Update. I thought it would be the same as Create but It seems not. I tried with HttpPut and HttpPost but nether called my API method.

  My API is a separate project than my UI. I am eventually going to be using a GateWay making it into a microservice.
  Currently I call my client.SendAsync(httpRequest);
  and it does not reach my API method at all, It does not call the API but all the other CRUD methods call it and works perfectly.
  I get a 400 bad request and 404 not found.

  // Here is my MVC View Controller that calls the API.
  public async Task<IActionResult> UpdateAppUser(string guid)
          {
              AppUser user = new AppUser();
              HttpRequestMessage httprequest = new HttpRequestMessage(HttpMethod.Post, $"https://localhost:5001/api/account/GetUserByID/{guid}");
              // httprequest.Content = new StringContent(guid);
  
              var client = apiClient.CreateClient();
              var response = await client.SendAsync(httprequest);
  
              if (response.IsSuccessStatusCode)
              {
                  var responseString = await response.Content.ReadAsStringAsync();
                  user = JsonConvert.DeserializeObject<AppUser>(responseString);
                 // return View("AppUser", user);
              }/**/
  
  
              return View(user);
          }
          //[Bind("FirstName,LastName,Email")]
          [HttpPost]
          [ValidateAntiForgeryToken]
          public async Task<IActionResult> UpdateAppUser(AppUser user)
          {
              if (ModelState.IsValid)
              {
                  RegisterModel registerModel = new RegisterModel
                  {
                      Username = user.userName,
                      FirstName = user.firstName,
                      LastName = user.lastName,
                      DateCreated = user.dateCreated,
  
                  };
                  //var model = JsonConvert.SerializeObject(user);
                  var model = JsonConvert.SerializeObject(registerModel);
  
                  HttpRequestMessage httpRequest = new HttpRequestMessage(HttpMethod.Post, $"https://localhost:5001/api/account/UpdateUser/");
                  httpRequest.Content = new StringContent(model, Encoding.UTF8, "application/json");
  
                  var client = apiClient.CreateClient();
                  var response = await client.SendAsync(httpRequest);
                  
                  if (response.IsSuccessStatusCode)
                  {
                      return View("AppUserIndex");
                  }
              }
              return View(user);
          }
  // Here is the API
  [HttpPost("UpdateUser")]
          //[Route("UpdateUser")]
          public async Task<IActionResult> UpdateUser(RegisterModel registerModel)
          {
              if (ModelState.IsValid)
              {
                  var user = await userManager.FindByEmailAsync(registerModel.Email);
                  if (user != null)
                  {
                      user.Email = registerModel.Email;
                      user.UserName = registerModel.Username;
                      user.FirstName = registerModel.FirstName;
                      user.LastName = registerModel.LastName;
  
                      IdentityResult validEmail = null;
                      if (!string.IsNullOrEmpty(registerModel.Email))
                      {
                        //  validEmail = await 
                      }
  
                      IdentityResult identityResult = await userManager.UpdateAsync(user);
                      if (identityResult.Succeeded)
                      {
                          return Ok();
                      }
                  }
                  else
                      return NotFound();
              }
              return BadRequest();
          }

  Hi,ExceedingLife

  I tried with HttpPut and HttpPost but nether called my API method.

  • Make sure the port is correct and it can find the action correctly.

  HttpRequestMessage httpRequest = new HttpRequestMessage(HttpMethod.Post, $"https://localhost:44306/account/UpdateUser/");

  • I tested these code without the 'gateway' and they works well, so the problem may lies on it, you should check whether your gateway can work well

  I get a 400 bad request and 404 not found.

  Could you please tell us about their scenes?

  • 400 bad request  often caused by the bad request, means the request can not access the action.
  • 404 error often means can not find the url.

  You can set break point to check whether you have these mistakes.

  Best Regards,

  When I use PostMan or Swagger my Update API call works and updates the data.

  Making sure I have the correct port and uri it gets 'BadRequest 400'

  I am currently not using a gateway I am using a MVC UI to call my API Project. Everything works Except Update.

  Looking at this some more, I am thinking it could be something with the page possibly itself..

  I switched my  form from UpdateUser to CreateUser and it calls the CreateUser action then when I call my httprequest for CreateUser it gets 'BadRequest 400' but when I do create User on my Create page it works with the 200 success.

  I found the issue!!!

  It looks like you CaNNOT convert object types.

  I was inserting AppUser in the view. and the API method took RegisterUser.

  In the mvc method i would convert appuser to registeruser and pass it in.

  that was my bad request.
