Examples

Basic use

package main

import (
	"encoding/xml"
	"log"
	"net/http"
	"time"

	"github.com/tiaguinho/gosoap"
)

// GetIPLocationResponse will hold the Soap response
type GetIPLocationResponse struct {
	GetIPLocationResult string `xml:"GetIpLocationResult"`
}

// GetIPLocationResult will
type GetIPLocationResult struct {
	XMLName xml.Name `xml:"GeoIP"`
	Country string   `xml:"Country"`
	State   string   `xml:"State"`
}

var (
	r GetIPLocationResponse
)

func main() {
	httpClient := &http.Client{
		Timeout: 1500 * time.Millisecond,
	}
	soap, err := gosoap.SoapClient("http://wsgeoip.lavasoft.com/ipservice.asmx?WSDL", httpClient)
	if err != nil {
		log.Fatalf("SoapClient error: %s", err)
	}
	
	// Use gosoap.ArrayParams to support fixed position params
	params := gosoap.Params{
		"sIp": "8.8.8.8",
	}

	res, err := soap.Call("GetIpLocation", params)
	if err != nil {
		log.Fatalf("Call error: %s", err)
	}

	res.Unmarshal(&r)

	// GetIpLocationResult will be a string. We need to parse it to XML
	result := GetIPLocationResult{}
	err = xml.Unmarshal([]byte(r.GetIPLocationResult), &result)
	if err != nil {
		log.Fatalf("xml.Unmarshal error: %s", err)
	}

	if result.Country != "US" {
		log.Fatalf("error: %+v", r)
	}

	log.Println("Country: ", result.Country)
	log.Println("State: ", result.State)
}

Set Custom Envelope Attributes

	"log"
	"net/http"
	"time"

	"github.com/tiaguinho/gosoap"
)

// GetIPLocationResponse will hold the Soap response
type GetIPLocationResponse struct {
	GetIPLocationResult string `xml:"GetIpLocationResult"`
}

// GetIPLocationResult will
type GetIPLocationResult struct {
	XMLName xml.Name `xml:"GeoIP"`
	Country string   `xml:"Country"`
	State   string   `xml:"State"`
}

var (
	r GetIPLocationResponse
)

func main() {
	httpClient := &http.Client{
		Timeout: 1500 * time.Millisecond,
	}
	// set custom envelope
    gosoap.SetCustomEnvelope("soapenv", map[string]string{
		"xmlns:soapenv": "http://schemas.xmlsoap.org/soap/envelope/",
		"xmlns:tem": "http://tempuri.org/",
    })

	soap, err := gosoap.SoapClient("http://wsgeoip.lavasoft.com/ipservice.asmx?WSDL", httpClient)
	if err != nil {
		log.Fatalf("SoapClient error: %s", err)
	}
	
	// Use gosoap.ArrayParams to support fixed position params
	params := gosoap.Params{
		"sIp": "8.8.8.8",
	}

	res, err := soap.Call("GetIpLocation", params)
	if err != nil {
		log.Fatalf("Call error: %s", err)
	}

	res.Unmarshal(&r)

	// GetIpLocationResult will be a string. We need to parse it to XML
	result := GetIPLocationResult{}
	err = xml.Unmarshal([]byte(r.GetIPLocationResult), &result)
	if err != nil {
		log.Fatalf("xml.Unmarshal error: %s", err)
	}

	if result.Country != "US" {
		log.Fatalf("error: %+v", r)
	}

	log.Println("Country: ", result.Country)
	log.Println("State: ", result.State)

Functions

func GetPayloadFromError

func GetPayloadFromError(err error) []byte

GetPayloadFromError returns the payload of a ErrorWithPayload

func IsFault

func IsFault(err error) bool

IsFault returns whether the given error is a fault error or not.

IsFault will return false when the error could not be typecasted to FaultError, because every fault error should have it's dynamic type as FaultError.

func SetCustomEnvelope

func SetCustomEnvelope(prefix string, attrs map[string]string)

SetCustomEnvelope define customizated envelope
