Invalid Signature - provided signature does not match

Here is my code. I am trying my angularJS app to interact with the Woocommerce API over HTTP (NOT HTTPS).

`var oauth = OAuth({ consumer:{ public: ck, secret: cs }, signature_method: ‘HMAC-SHA1’, last_ampersand: false });

var request_data = {
  url: url,
  method: 'GET'
};

var token = {
  public: '370773112-GmHxMAgYyLbNEtIKZeRNFsMKPR9EyMZeS9weJAEb',
  secret: 'LswwdoUaIvS8ltyTt5jkRh4J50vUPVVHtR2YPi5kE'
};

$http({
  url: request_data.url,
  method: request_data.method,
  params: oauth.authorize(request_data, token)
}).then(function(data){
  console.log(data);
}, function(error){
  console.log(error);
})`

I always get the following error.

errors: [ { code: "woocommerce_api_authentication_error", message: "Invalid Signature - provided signature does not match" } ]

Any help is highly appreciated.

Yes. this is weird. I don’t know if you have resolved it or not!

I am getting Invalid Signature - provided signature does not match.

I have no Idea why this is happening. I use the same cs & ck on insomnia and it works…

import { Request } from "express";
import crypto from 'crypto';

import IOAuth1Provider from "../interfaces/IOAuth1Provider";
import OAuth from "oauth-1.0a";

export default class OAuth1Provider implements IOAuth1Provider {
    oauth: OAuth;

    constructor() {
        this.oauth = new OAuth({
            consumer: { key: `${process.env.WP_CONSUMER_KEY}`, secret: `${process.env.WP_CONSUMER_SECRET}` },
            signature_method: 'HMAC-SHA1',
            hash_function(base_string, key) {
                return crypto
                    .createHmac('sha1', key)
                    .update(base_string)
                    .digest('base64')
            },
        })
    }
    makeHeader(request: Request): OAuth.Header {
        return this.oauth.toHeader(this.oauth.authorize(request));
    }

}
