Basic authorization on createClient call

[oriolAltran]

Hi Luca,

first of all, thanks for your work with this library.

I'm trying to access to a WSDL that requires basic authorization. I added a wsdl header for do it, but don't work. If I look the request that browser sends to server, doesn't have the authorizathion header.

  this.soap.createClient('http://spolsapt50:8000/sap/bc/srt/wsdl/flv_10002A111AD1/srvc_url/sap/bc/srt/rfc/sap/z_sga_get_menu', 
    {wsdl_headers: {Authorization: `Basic ` + btoa('sc5301:xxxxxxxx')}})
  .then(client => {
    console.debug;
    client.addHttpHeader('Authorization', 'Basic ' + btoa('sc5301:xxxxxxxx'));
  })
  .catch(err => {
    console.log('Error', err);
  });  

I've debuged the call to createClient and I saw this code (I've deleted some commented lines):

function open_wsdl(uri, options) {
    return __awaiter(this, void 0, void 0, function* () {
        // initialize cache when calling open_wsdl directly
        let WSDL_CACHE = options.WSDL_CACHE || {};
        let request_headers = options.wsdl_headers;
        let request_options = options.wsdl_options;
        const httpClient = options.httpClient;
        const wsdlDef = yield httpClient.get(uri, { responseType: 'text' }).toPromise();
        const wsdlObj = yield new Promise((resolve) => {
            const wsdl = new WSDL(wsdlDef, uri, options);
            WSDL_CACHE[uri] = wsdl;
            wsdl.WSDL_CACHE = WSDL_CACHE;
            wsdl.onReady(resolve(wsdl));
        });
        return wsdlObj;
    });

I saw that http request is sent in "const wsdlDef = yield httpClient.get(uri, { responseType: 'text' }).toPromise();" line, but in this line options parameter is not used. This call already returns a 401 error.

Any idea? Is this behavior normal?

I tried to customize your module with your instructions in https://github.com/lula/ngx-soap#local-development, but "npm install" throws this error .

C:\App\ngx-soap>npm install

I'm a little frustrated, all my intents go wrong, could you help me?

Thanks in advance!!
