WsCancelPNR: Cancel PNR/Booking Method

Cancel PNR (WsCancelPNR) is a service method to canceling active PNR/Booking Code from Sriwijaya Air Web Service (SOAP) v.111 [1].

In this example you will learn about using Cancel PNR Method (WsCancelPNR) with Go (using sjwsdk111 package).

The following are the sections available in this guide.

• What you'll build
• Prerequisites
• Implementation
• Build and Running

What you’ll build

Let’s make a real world simple application for canceling PNR/Booking using Sriwijaya Air Web Services Endpoint. Following diagram demonstrates the cancel PNR use case.

Prerequisites

• Sriwijaya Air Web Service (SOAP) Client for Go (sjwsdk111 GoLang package)

go get github.com/ClientSDK/sriwijaya-ws-client-go/sjwsdk111

• A Text Editor or an IDE

Sriwijaya Air Agent requirements

• Sriwijaya Air Agent Credential Account (Agent Application)
• Sriwijaya Air Web Service Access (IP Whitelist) ( Production, Development )
• WSDL File ( Production, Development )

Implementation

If you want to skip the basics, you can download the git repo and directly move to the "Build and Running" section by skipping "Implementation" section.

Example structure

Go is a complete programming language that supports custom project structures. Let's use the following package structure for this example.

sjwsv111
    ├── by-features
    │   ├── 01.WsCancelPNR
    │   │   ├── README.md
    │   │   ├── build_and_run.sh
    │   │   └── main.go
    └── wsdl
        └── wsp-wsdl.eticketv111.wsdl

• Create the above directories in your local machine and also create empty main.go and build_and_run.sh files.

• Download Sriwijaya Air Web Service WSDL and saved to wsp-wsdl.eticketv111.wsdl.

Developing the application

Let's make a simple application for canceling PNR/Booking by using sjwsdk111 package.

Main code for WsCancelPNR (main.go)

package main

import (
	"crypto/tls"
	"encoding/xml"
	"fmt"
	"net/http"
	"net/url"

	"github.com/ClientSDK/sriwijaya-ws-client-go/sjwsdk111"
)

func makeHTTPClient() *http.Client {
	// Access via proxy if needed
	proxyURL, _ := url.Parse("http://proxy-ip-address:proxy-port")
	//proxyURL, _ := url.Parse("http://proxy-user:proxy-password@proxy-ip-address:proxy-port")

	// Initite transport with proxy and skip TLS (if needed)
	tr := &http.Transport{
		Proxy:           http.ProxyURL(proxyURL),
		TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
	}

	// Initiate transport without proxy and skip TLS (if needed)
	// tr := &http.Transport{
	// 	TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
	// }

	httpClient := &http.Client{Transport: tr}

	return httpClient
}

func main() {

	// Initiate http client
	httpClient := makeHTTPClient()

	// Initiate NewSoapSJClient version 111
	sjClient, err := sjwsdk111.NewSoapSJClient(httpClient, "../../wsdl/wsp-wsdl.eticketv111.wsdl", "file")
	if err != nil {
		fmt.Println(err)
	}

	// call Sriwijaya web service operation
	callWsCancelPNR(sjClient)
}

// callWsCancelPNR is a function to call WsCancelPNR method
func callWsCancelPNR(s *sjwsdk111.SoapSJClient) {
	params := []byte(
		`
			<Username xsi:type="xsd:string">SRIWIJAWA_AGENT_USERNAME</Username>
			<Password xsi:type="xsd:string">SRIWIJAWA_AGENT_PASSWORD</Password>
			<BookingCode xsi:type="xsd:string">ACTIVE_PNR_CODE_OR_BOOKING_CODE_FROM_WS_GENERATE_PNR_RESPONSE</BookingCode>
			`)
	wsResp, errC := s.CallWsCancelPNR(params, false)

	if errC != nil {
		fmt.Println(errC)
		return
	}

	// Access response variable
	// fmt.Println()
	// fmt.Println("ReturnData-WsCancelPNR:")
	// fmt.Printf("%#v\n", wsResp.Return)

	// Marshal response variable to XML
	myXML, _ := xml.MarshalIndent(wsResp, " ", "  ")
	fmt.Println(string(myXML))
}

Bash code for building and running the example application (build_and_run.sh)

echo "Clean..."
rm ./WsCancelPNR
echo "Build..."
go build -o WsCancelPNR main.go 
echo "Build Done."
echo "Run..."
./WsCancelPNR > WsCancelPNR-Result.xml
echo "Done."

Build and Running

You can build and running by execute the "build_and_run.sh" bash files.

   $ sh build_and_run.sh 

After the application is running, you will get the xml response in WsCancelPNR-Result.xml files.

Sample Response

 <WsCancelPNRResponse>
   <return>
     <Username>SRIWIJAWA_AGENT_USERNAME</Username>
     <BookingCode>ABMNYZ</BookingCode>
     <ErrorCode>CANCEL0000</ErrorCode>
     <ErrorMessage>Success.</ErrorMessage>
   </return>
 </WsCancelPNRResponse>
