Here is my code for my GET
singleChatModel = new Dashboard.Collections.MessagesCollection();
singleChatModel.fetch({
data:{
userId: userId,
id: chatId
}
});
and here is the C#
[WebGet(UriTemplate = "?userId={userId}&id={id}")]
public MessageServiceModel[] GetAllMessages (string userId, string id)
{
....
}
the request URL
Request URL:http://localhost:1087/apps/messages/Messages/?userId=RJGILL&id=1
That all works great for the get, but I'm having trouble getting into the POST, PUT methods
Here is my POST
newMessage = new Dashboard.Models.MessagesModel;
newMessage.set(messageObj);
newMessage.save({
success: function() {...}
});
and the C#
[WebInvoke(UriTemplate = "?userId={userId}&id={id}", Method = "POST")]
public void AddNewMessage(string userId, string id, string text)
{
...
return;
}
and here is the error that I get
POST http://localhost:1087/apps/messages/Messages/ 400 (Bad Request)
I need to manipulate the URL so that it is matches my UriTemplate.
Can I perform the POST / PUT with the same setup using the 'data' object as I am with the GET?

I am in the middle of learning react/redux and decided to take an old JQuery UI that makes request to Spring REST API and rewrite it in React. I am using Axios to make the request. In my old Query UI , I do the following when a form is submitted.
var formInputs = $(form).serialize();
$.post("/addAttrItem", formInputs, function(updated){
refresh();
showRecord(updated);
displayControlMsg("Record below was added successfully");
}
This is handled by the following code below in Spring
#ResponseBody
#RequestMapping(value="/someURL", method=RequestMethod.POST)
public AttrItem restfulAdd(AttrItem item) throws Exception
{
item.setLastUpdate(new java.util.Date());
itemService.create(item);
return item;
}
When sending the request through JQuery, AttrItem item param populated with all right values sent in by JQuery
However when I try the following axios
axios.post(someUrl, data).then
(res => {
dispatch(addAttributeSync(res));
}).catch(error =>{
alert('add item failed ' + error);
}
the AttrItem item param while not null itself, is empty with none of the fields set to values from the form. I confirmed that the data object contains right data prior to the post request.
See if mapping the HTTP request body to the method argument item using #RequestBody annotation helps.
#ResponseBody
#RequestMapping(value="/someURL", method=RequestMethod.POST)
public AttrItem restfulAdd(#RequestBody AttrItem item) throws Exception
{
item.setLastUpdate(new java.util.Date());
itemService.create(item);
return item;
}
The following seems to have resolved the issue. In React I added header config
return dispatch => {
var config = {
headers: { 'Content-Type': 'application/json' },
};
axios.post(someUrl, data).then
(res => {
dispatch(addAttributeSync(res));
}).catch(error =>{
alert('add item failed ' + error);
}
And I modified my Spring Controller endpoint to set the consumes and produces attribute as follows.
#ResponseBody
#RequestMapping(value="/attributeItem", method=RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
public AttributeItem restfulAdd(#RequestBody AttributeItem attributeItem) throws Exception
{
attributeItem.setLastUpdate(new java.util.Date());
attributeItemService.create(attributeItem);
return attributeItem;
}
I am working on a project using angularjs+springboot. Am trying to send email via my application using spring-boot-starter-mail. The message and object of the email are written by the user in a form. what I want to do is to get the message and object values in my RestController using #RequestBody.
the function in my service.js
// send mail
var sendMail = function(id, objet, msg) {
var deferred = $q.defer();
$http.post(urlBase + id, objet, msg).then(
function(response) {
deferred.resolve(response.data);
}, function(errResponse) {
console.error('Error while sending email');
deferred.reject(errResponse);
});
return deferred.promise;
}
the method in my restContoller
#RestController
public class EmailController {
#Autowired
private JavaMailSender javaMailSender;
#Autowired
UtilisateurService service;
#RequestMapping(value = "/users/{id}", method = RequestMethod.POST)
public ResponseEntity<Void> sendMail(#PathVariable("id") int id, #RequestBody String objet,
#RequestBody String msg) {
Utilisateur currentUser = service.findById(id);
SimpleMailMessage message = new SimpleMailMessage();
message.setTo(currentUser.getEmailUtil());
message.setSubject(objet);
message.setText(msg);
javaMailSender.send(message);
return new ResponseEntity<Void>(HttpStatus.OK);
}}
This throws this exception :
Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing: public org.springframework.http.ResponseEntity<java.lang.Void> com.sla.utilisateur.controller.EmailController.sendMail(int,java.lang.String,java.lang.String)
How can I fix it?
thank you,
Your usage of $http.post is not correct. You should have a look at the AngularJS POST documentation. $http.post arguments are the following:
post(url, data, [config]);
AngularJS sends the data by default in JSON. So you should send the request using the following statement (for example):
$http.post(urlBase + id, {subject:objet, body:msg})
And in your controller you should define only one #RequestBody maps for the ease of the example to a Map (You could change it to a POJO. ):
#RequestMapping(value = "/users/{id}", method = RequestMethod.POST)
public ResponseEntity<Void> sendMail(#PathVariable("id") int id, #RequestBody Map<String,String> msg) {
Utilisateur currentUser = service.findById(id);
SimpleMailMessage message = new SimpleMailMessage();
message.setTo(currentUser.getEmailUtil());
message.setSubject(msg.get("subject");
message.setText(msg.get("body"));
javaMailSender.send(message);
return new ResponseEntity<Void>(HttpStatus.OK);
}}
I am using AngularJs and Resources module. I want to do a GET to obtain an object.. to do this GET I do not have to pass simply the ID to the server, but I should pass a complex object with different properties and values..
Here the code I am using:
$scope.getActivationStatus = function (event) {
event.preventDefault();
if ($scope.segui_attivazione_form.$valid) {
$scope.activationStatus =
new SeguiAttivazioneService
.seguiAttivazione()
.$get(
{
request: $scope.activationStatus
}, function () { });
}
};
On server side I have:
[HttpGet]
public IHttpActionResult GetActivationStatus(MyComplexObject request)
{
//I will do something here later...
return Ok();
}
The problem is that "request" arrive on server equals to NULL...
I have solved the problem passing two strings to the server... in this way:
$scope.getActivationStatus = function (event) {
event.preventDefault();
if ($scope.segui_attivazione_form.$valid) {
$scope.activationStatus =
new SeguiAttivazioneService
.seguiAttivazione()
.$get(
{
codiceFiscale: $scope.activationStatus.CodiceFiscale,
codiceRichiesta: $scope.activationStatus.CodiceRichiesta
}, function () { });
}
};
And server side:
[HttpGet]
public IHttpActionResult GetActivationStatus(string codiceFiscale, string codiceRichiesta)
{
return Ok();
}
In this way everything works... but I don't like this solution because I will have more than two input...
And this is a get, not a post (not a save, an update)...
How can I pass a complex object doing a GET?
Thank you...
It's best to use the POST method if you want to send data in the body of the request. While it's possible with Angular, some servers might ignore the body of GET requests.
This approach allows to send complex objects with arrays and sub objects:
Angular:
$http({
url: '/myApiUrl',
method: 'GET',
params: { param1: angular.toJson(myComplexObject, false) }
})
C#:
[HttpGet]
public string Get(string param1)
{
Type1 obj = new JavaScriptSerializer().Deserialize<Type1>(param1);
...
}
This is not an elegant solution but it works using HTTP GET:
$http.get(url + "?" + $.param(obj).replace(/%5b([^0-9].*?)%5d/gi, '.$1'))
It converts the complex object into a string with dot notation to define levels. Most of the server side frameworks like ASP.NET Core can bind it to complex objects.
This is an example of the string I send for a complex object:
StartDate=2021-06-11&EndDate=2021-06-11&TimeRange.TimeFrom.Time=07%3A00&TimeRange.TimeFrom.TimeFrame=AM&TimeRange.TimeTo.Time=10%3A00&TimeRange.TimeTo.TimeFrame=AM
Request body can only be sent by POST. With get you could at best URL Encode the OBJECT and then send it as query string params. But thats not the best solution to post some data to the server
I'm receiving a 405 error with a POST request using $http.post. What's weird is that I'm using $http.post in another area of my application and it works just fine.
I'm using AngularJS for client side, and Web API for server side. I've posted all relevant information (apart from my web.config) that I can think of. Is there something very obvious I'm missing here?
code below does not work (throws 405)
Here's the api controller method that I'm trying to hit:
public async Task<IHttpActionResult> LinkLogin(string provider)
{
Account user = await _repo.FindByNameAsync(User.Identity.Name);
if (user == null)
{
return BadRequest("User does not exist!");
}
return new ChallengeResult(provider, null, "auth/Manage/LinkLoginCallback", user.Id);
}
Here's how I'm trying to hit it on the client side:
var _linkLogin = function (provider) {
$http.post(serviceBase + 'auth/Manage/LinkLogin', provider).then(function (response) {
return response;
});
};
CODE BELOW IS CODE THAT WORKS
Api controller function that works:
// POST auth/Authorization/Register
[AllowAnonymous]
[Route("Register")]
public async Task<IHttpActionResult> Register(UserModel userModel)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
IdentityResult result = await _repo.RegisterUser(userModel);
IHttpActionResult errorResult = GetErrorResult(result);
if (errorResult != null)
{
return errorResult;
}
return Ok();
}
Calling it from the client side:
var _saveRegistration = function (registration) {
_logOut();
return $http.post(serviceBase + 'auth/Authorization/register', registration).then(function (response) {
return response;
});
};
Here is my web api configuration:
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API routes
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "AuthenticationApi",
routeTemplate: "auth/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
config.Routes.MapODataServiceRoute("ODataRoute", "api", GenerateEdmModel());
var jsonFormatter = config.Formatters.OfType<JsonMediaTypeFormatter>().First();
jsonFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
}
private static IEdmModel GenerateEdmModel()
{
ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
return builder.GetEdmModel();
}
}
Now I have tried a number of different solutions posted on the web to no avail, the following are links to things I have tried:
Web api not supporting POST method
Web API Put Request generates an Http 405 Method Not Allowed error
http://blog.dontpaniclabs.com/post/2013/01/23/That-Pesky-Requested-Resource-Does-Not-Support-HTTP-Method-POST-Error-When-Using-MVC-Web-API
I hate answering my own question. If anyone else runs into this issue it's because you're trying to send a simple string value to a web api controller.
I used this solution with success: http://jasonwatmore.com/post/2014/04/18/Post-a-simple-string-value-from-AngularJS-to-NET-Web-API.aspx
If the link is dead, you simple wrap the string value in double quotes in your POST request like so:
$http.post(Config.apiUrl + '/processfile', '"' + fileName + '"');
So I'm attempting to attach to a web api method via a WPF service, but get only a 500 error on anything other than a GET.
WPF call:
using (var client = new HttpClient())
{
var user = new MyUser
{
EntityID = Guid.NewGuid(),
FirstName = "WPF",
LastName = "test"
};
var formatter = new JsonMediaTypeFormatter();
HttpContent content = new ObjectContent<MyUser>(user, formatter);
client.BaseAddress = new Uri("http://localhost:19527/api/");
var response = await client.PostAsJsonAsync("MyUser", content);
//.ContinueWith((postTask) => result = (postTask.Result.Content == null) ? "Could not create user" : "User created successully!");
var r = response.StatusCode;
}'
...and the receiving controller:
public HttpResponseMessage Get(string badgeId)
{
return Request.CreateResponse<bool>(HttpStatusCode.OK, (service.UserByBadge(badgeId) != null));
}
public HttpResponseMessage Put(MyUser user)
{
return Request.CreateResponse<bool>(HttpStatusCode.OK, service.UpsertUser(user));
}
public HttpResponseMessage Post(MyUser user)
{
if (service.UpsertUser(user)) return Request.CreateResponse<MyUser>(HttpStatusCode.OK, service.Get<MyUser>(u => u.BadgeID == user.BadgeID));
return Request.CreateResponse<MyUser>(HttpStatusCode.NoContent, null);
}'
The service on the WebApi controller is a GenericRepository, which is working fine, since the Get method returns as expected. It's only when I use Post that I get the error. Debugging the methods throws the break point in the Get, but not in the Post, so I don't think it's ever being called.
Here's the route config:
routes.MapRoute(
name: "Default",
url: "api/{controller}/{action}/{id}",
defaults: new { controller = "{controller}", action = "{action}", id = UrlParameter.Optional }
);
I've tried different examples from other SO posts, but none appear to address this issue specifically. I'm guessing there's something wrong with how I've constructed the Post() method?
================================================================
RESOLUTION: Model being passed was failing property validations. Why this was causing a 500, not certain. But once I solved for this, API method began working.
If anybody has a "why" explanation, would love to know for future reference.
