HTTP Native Plugin (IONIC 3) - json

Question

I'm trying to make a post request using the HTTP cordova plugin. However, for some reason, the JSON data consumed by the Server side is not being formatted correctly (json brakets). Could anyone help me please?
The import:
import { HTTP } from '#ionic-native/http';
The request implementation:
public sendData(sufix, json) {
return new Promise((resolve, reject) => {
this.http.post(URL+sufix, JSON.stringify(json), {'Content-Type': 'application/json'}).then(result => {
resolve(result.data);
}).catch(error => {
reject(error);
});
});
}
The json sended:
{name: 'Test'}
The content received by the server:
=%7B%22name%22%3A%22Test%22%7D
The server implementation:
#Path("/register")
public class RegisterEndPoint {
#POST
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
public Response registerUser(UserDTO userDTO) {
// Create DAO for persistence
FactoryDAO factory = new FactoryDAO();
UserDAO userDAO = factory.getUserDAO();
// Create user to be persisted
if (!userDAO.userExist(userDTO.getEmail())) {
User user = new User();
user.setPassword(userDTO.getPassword());
user.setEmail(userDTO.getEmail());
user.setName(userDTO.getName());
userDAO.persist(user);
userDAO.commit();
return Response.status(200).build();
}
return Response.status(405).entity(new ErrorDTO("User already registered!")).build();
}
}

The problem seems to be in Native Plugin, so I've changed to the angular http solution, and it works fine. Follow below the solution which I've perform. Thanks everyone who helped me.
The imports required:
import { Http, Headers, RequestOptions, Response } from '#angular/http';
import { Observable } from 'rxjs/Rx'
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/do';
import 'rxjs/add/operator/timeout';
AuthProvider:
public sendRequest(sufix, json) {
let headers = new Headers({ 'Content-Type': 'application/json' });
let options = new RequestOptions({ headers: headers });
return this.http.post(URL+sufix, json, options)
.timeout(TIMEOUT_REQUEST*1000)
.do(this.logResponse)
.map(this.extractData)
.catch(this.handleError)
}
private logResponse(res: Response) {
console.log(res);
}
private extractData(res: Response) {
return res.json();
}
private handleError(res: Response | any) {
return Observable.throw(res.json().error || 'Fail to connect to the server');
}
Calling the AuthProvider:
this.authProvider.sendRequest('register', this.signup).subscribe((data) => {
console.log('Success!');
}, (error) => {
console.log(error);
});
Providers included in app.module.ts
import { HttpModule, JsonpModule } from '#angular/http';

can you please try sending the body without making it a string. you can send the JSON Object without stringify. Give it a try :)
**UPDATE
After sending this
{name: 'Test'}
If you are getting name = "test"
Why dont you try like this
var data = JSON.stringify(data);
var obj = {data:data};
//send the obj Object
So it will show as data = "{name:test}"
Now Parse it from the server. Try and let me know :)

if you are trying to make post request using HTTP then try sending request in this format.
let body = new FormData();
body.append('name', 'Test');
this.http.post(<url>,body);
Try and lemme know if it works for you.

Just add this.http.setDataSerializer(‘json’) before do the post
