    TransactionRequest request = new TransactionRequest();

    request.setOrderId("1242").setCurrency("MAD").setAmount(1500);
    request.setShippingType(ShippingType.VIRTUAL);
    request.setPaymentMode(PaymentMode.SINGLE);
    request.setPaymentType(PaymentType.CREDIT_CARD);

        console.log(data);
      },
      err=>{
        console.log(err);
    });
  } 

Answer 1

You expect JSON but you get HTML:

//service : 
    public testPaiementEnLigne2(){
        return 
         this.http.get(this.baseUrl+"payzone/create").map(data=>data.text());
    }
