My function:

 post(link, data): Promise<any> {
    return new Promise((resolve, reject) => {
      if (this.isOnline()) {

        data = Object.assign(data, {rnd: new Date().getTime()});

        if (this.debug_mode) {
          console.log("datadata", data);
        }

        let params = " params: ";
        for (let field in data) {
          if (field == "p") {
            params += " p:*****"
          }
          else
            params += " " + field + ":" + data[field];
        }

        if (this.debug_mode) {
          console.log('data_params', data);
          console.log("params", params);
        }

        this.logProvider.writeLog("RETRIEVE: start post on link " + link + " " + params);

        this.http.sendRequest(link,
            {
              method: 'post',
              data: data,
              timeout: 30000
            }
        ).then(result => {

          // prints 200
          console.log(result.status);


          try {
            result.data = JSON.parse(result.data);
            // prints test
            console.log(result.data.message);
          } catch (e) {
            console.error('JSON parsing error');
          }

          this.logProvider.writeLog("RETRIEVE: finish post on link " + link);

          if (this.debug_mode) {
            console.log("result.data", result.data);
          }

          //console.log("result", result);
          resolve(result.data);

          // prints 200
          console.log(result.status);
        }).catch(err => {

          // A client-side or network error occurred. Handle it accordingly.

          if (this.debug_mode) {
            console.log('An error occurred post:', err);
          }

          this.logProvider.writeLog("ERROR: error in answer from server " + err.error + " status " + err.status + " link " + link + params);

          reject(err.error);

          // prints 403
          console.log(err.status);

          // prints Permission denied
          console.log(err.error);
        });


     
      } else {
        this.logProvider.writeLog("going to post on link " + link + " but device is offline");
        reject({text: "device is offline"});
      }

    });
