API

constructor(servicePort, serviceRoot, targetNamespace)

SoapService constructor - invoked via Angular 2 provider, or JavaScript new

servicePort

argument string

the protocol, resource name, and port upon which the service endpoint is deployed

serviceRoot

argument string

the path to the webservice endpoint

targetNamespace

optional argument string

prefixes the webservice method in the HTTP request header SOAPAction

envelopeBuilder

property (requestBody:string) => string

a callback function to build the SOAP request envelope

jsoResponseHandler

property (response:{}) => void

a callback function to receive the JavaScript webservice response object (https://github.com/autopulous/xdom2jso.git)

xmlResponseHandler

property (response:NodeListOf<Element>) => void

a callback function to asynchronously consume the XML webservice response

localNameMode

property boolean

when true causes the XML webservice response conversion to omit ELEMENT and ATTRIBUTE name namespaces within the JavaScript object

debugMode

property boolean

when true causes webservice request/response debug messages to be sent to the console

testMode

property boolean

when true causes the HTTP request to be processed synchronously and sets debugMode to true (used for unit testing or diagnostics)

post(method, parameters, responseRoot)

method returning void

method

argument string

HTTP request header SOAPAction method

parameters

argument {} (JavaScript object)

the body of the webservice request

responseRoot

optional argument string

the starting ELEMENT within the XML webservice response from which to convert into the JavaScript response object

Usage Notes

• By default autopulous-angular2-soap processes SOAP responses asynchronously (this behavior is overridden by setting testMode)

Example

A user authentication service to make SOAP requests and process SOAP responses.

user.authenticator.ts

import {Component} from "@angular/core";
import {SoapService} from "../soap.service";

@Component({
    selector: 'authenticator',
    templateUrl: 'app/authenticator.component.html',
    providers: [SoapService]
})

export class UserAuthentication {
    private servicePort:string = 'http://172.16.62.111:8091';
    private servicePath:string = '/your-application-ws/ws/';
    private targetNamespace:string = '';

    private responseJso:{} = null;

    private soapService:SoapService;

    constructor() {
        this.soapService = new SoapService(this.servicePort, this.servicePath, this.targetNamespace);
        this.soapService.envelopeBuilder = this.envelopeBuilder;
        this.soapService.jsoResponseHandler = (response:{}) => {this.responseJso = response};
        this.soapService.localNameMode = true;
    }

    private username:string = '';
    private password:string = '';

    public login(username:string, password:string) {
        var method:string = 'Login';
        var parameters:{}[] = [];

        this.username = username;
        this.password = password;

        parameters['LoginRequest xmlns="urn:application:security:messages:1:0"'] = UserAuthentication.userLogin(username, password);

        this.soapService.post(method, parameters);
    }

    private static userLogin(username, password):{}[] {
        var parameters:{}[] = [];

        parameters["UserName"] = username;
        parameters['Password'] = password;

        return parameters;
    }

    private envelopeBuilder(requestBody:string):string {
        return "<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\">" +
               "<SOAP-ENV:Header>" +
               "<wsse:Security SOAP-ENV:mustUnderstand=\"1\" xmlns:wsse=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd\" soapenv =\"http://schemas.xmlsoap.org/soap/envelope/\">" +
               "<wsse:UsernameToken wsu:ld=\"UsernameToken-104\" xmlns:wsu=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\" >" +
                "<wsse:Username>" + this.username + "</wsse:Username>" +
                "<wsse:Password Type=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText\">" + this.password + "</wsse:Password>" +
                "</wsse:UsernameToken>" +
                "</wsse:Security>" +
                "</SOAP-ENV:Header>" +
                "<SOAP-ENV:Body>" +
                requestBody +
                "</SOAP-ENV:Body>" +
                "</SOAP-ENV:Envelope>";
    }
