        String url2 = "https://" + app + "/" + tenant + "/" + policy + "/SelfAsserted?tx=" + this.transId + "&p=" + policy;
        this.httpPost = new HttpPost(url2);
        List<NameValuePair> nameValuePairs = new ArrayList(3);
        nameValuePairs.add(new BasicNameValuePair("request_type", "RESPONSE"));
        nameValuePairs.add(new BasicNameValuePair("signInName", email));
        nameValuePairs.add(new BasicNameValuePair("password", password));
        nameValuePairs.add(new BasicNameValuePair("g-recaptcha-response-toms", "03AEHxwuy8mq_8jbEWU--XHGea2dF-p7F-oUmZhAgpr1Xt7XyyrzBQpJZJilwhJZPG3D-K_HldpTEEl_2Xi51xm4ICCg6-w66XfR5nE1-Cj39ytH6QZiY2yJUTy-1CJZ6qNfJBsO7EG2Kba7cSGhQgetkhAxJOBtI-FJt5WlRdjP6UHgId11rSVhSCS2kphf1Z-BO62Fu2Jm6jWxnbTiVceEVXuQTOEibtQnQ-n2ckOLI-i0GI1tFBAVi6Lu6NZkQII7m_00ZyJtSoik-1LCNNQ8GXmOxFnnVTnvm-vr3mk_RmNaLS9CT6eGlo0CfpK3DiVTLEArQDTuxY"));

}

please find the below node function which is calling the same api

    accessTokenStep2 : (obj,env,email,password) => {

    let transId = obj.transid;
    let csrfId = obj.csrfId;
    let app = env.getAppUrl();
    let tenant = env.getTenantId();



    let policy = env.getPolicy();
    let url2 = ("https://" + app + "/" + tenant + "/" + policy + "/SelfAsserted");


    var options = {
        request_type   : "RESPONSE",
        signInName : "*********",
        password : "*****",
        "g-recaptcha-response-toms" : "03AEHxwuy8mq_8jbEWU--XHGea2dF-p7F-oUmZhAgpr1Xt7XyyrzBQpJZJilwhJZPG3D-K_HldpTEEl_2Xi51xm4ICCg6-w66XfR5nE1-Cj39ytH6QZiY2yJUTy-1CJZ6qNfJBsO7EG2Kba7cSGhQgetkhAxJOBtI-FJt5WlRdjP6UHgId11rSVhSCS2kphf1Z-BO62Fu2Jm6jWxnbTiVceEVXuQTOEibtQnQ-n2ckOLI-i0GI1tFBAVi6Lu6NZkQII7m_00ZyJtSoik-1LCNNQ8GXmOxFnnVTnvm-vr3mk_RmNaLS9CT6eGlo0CfpK3DiVTLEArQDTuxY",
        tx : transId,
        p : policy,

    };


 return new Promise( (resolve, reject) => {

     request({
      headers: [{
          'User-Agent'          :  'Mozilla/5.0 (Windows NT 10.0; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0',
          'Content-Type'        : 'application/x-www-form-urlencoded',
          'Accept'              : 'application/json, text/javascript, **/*//*; q=0.01',
          'X-Requested-With'    : 'XMLHttpRequest',
          'X-CSRF-TOKEN'        : csrfId
        }],
        url: url2,
        method: "POST",
        form   : options,
        json: true          
      }, function(error, response, body){

         // console.log(error);
          //console.log(body);
         (response.statusCode == 200 ? resolve(body) : resolve(error));
    });

 });

}

Answer 1

headers is an object rather than an array, see Custom HTTP Headers .

Try:

headers: {
    'User-Agent'          :  'Mozilla/5.0 (Windows NT 10.0; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0',
    'Content-Type'        : 'application/x-www-form-urlencoded',
    'Accept'              : 'application/json, text/javascript, **/*//*; q=0.01',
    'X-Requested-With'    : 'XMLHttpRequest',
    'X-CSRF-TOKEN'        : csrfId
},
