Whenever I make a POST request to the API in Ionic 2, I encounter a "Connection refused (x192)" error

Question

Whenever I make a POST request to the API in Ionic 2, I encounter a "Connection refused (x192)" error

I have been struggling with an error in my code for the past two days and I can't seem to find a solution. Can someone please help me with this?

The error message is as follows:

[Error] WebSocket network error: The operation couldn’t be completed. Connection refused (x192)
[Error] ERROR – Response {_body: XMLHttpRequestProgressEvent, status: 0, ok: false, …}
Response {_body: XMLHttpRequestProgressEvent, status: 0, ok: false, statusText: “”, headers: Headers, …}Response

Here is a snippet of the code that is causing the issue:

import { Http, Headers, RequestOptions } from ‘@angular/http’;
import { Injectable } from ‘@angular/core’;
import ‘rxjs/add/operator/map’;

/*
Generated class for the RestapiServiceProvider provider.

See https://angular.io/guide/dependency-injection for more info on providers
  and Angular DI.
*/

@Injectable()
export class RestapiServiceProvider {

    apiUrl = ‘http://localhost:8100/development/abc/public/api/v1/apiName’;

    constructor(public http: Http) {
        console.log(‘Hello RestapiServiceProvider Provider’);
    }

    getUsers() {
    
    // Code block goes here
    
    }
}

Answer №1

Here's a suggestion you could try to see if it helps:

Rather than using:

apiUrl = ‘http://localhost:8100/development/abc/public/api/v1/apiName’;

Make sure there is a port associated with it, like 8100 for Ionic. Check if your API is running on a different port and make the necessary adjustments:

apiUrl = ‘http://localhost:<some_other_port_number>/development/abc/public/api/v1/apiName’;

Another Approach:

I'm not sure how you're handling post data on your server side, but consider this:

Your current code:

               `let data1 = JSON.stringify({
                    user_id: 14,
                    token: “dsfdsffsfsffsdfffsdffsfs”
                });`

Instead, change it to:

               `let data1 = {
                    user_id: 14,
                    token: “dsfdsffsfsffsdfffsdffsfs”
                }`

The issue may be that you are sending just a string without any label or key:

this.http.post(this.apiUrl, data1, options)

So, data1 should be sent as a JSON Object, not a string

You can try this with or without using proxies, depending on how your client side operates.
