You are encouraged to solve this task according to the task description, using any language you may know.
In this task, the goal is to create a SOAP client which accesses functions defined at http://example.com/soap/wsdl, and calls the functions soapFunc( ) and anotherSoapFunc( ).
ActionScript
<lang actionscript>import mx.rpc.soap.WebService; import mx.rpc.events.ResultEvent; var ws:WebService = new WebService(); ws.wsdl = 'http://example.com/soap/wsdl'; ws.soapFunc.addEventListener("result",soapFunc_Result); ws.anotherSoapFunc.addEventListener("result",anotherSoapFunc_Result); ws.loadWSDL(); ws.soapFunc(); ws.anotherSoapFunc(); // method invocation callback handlers private function soapFunc_Result(event:ResultEvent):void {
// do something
} private function anotherSoapFunc_Result(event:ResultEvent):void {
// do another something
}</lang>
AutoHotkey
using embedded vb scripting.
<lang AutoHotkey>WS_Initialize()
WS_Exec("Set client = CreateObject(""MSSOAP.SoapClient"")") WS_Exec("client.MSSoapInit ""http://example.com/soap/wsdl""") callhello = client.soapFunc("hello") callanother = client.anotherSoapFunc(34234) WS_Eval(result, callhello) WS_Eval(result2, callanother) Msgbox % result . "`n" . result2 WS_Uninitialize()
- Include ws4ahk.ahk ; http://www.autohotkey.net/~easycom/ws4ahk_public_api.html</lang>
C
Although this is a generic task to show that calling SOAP functions are possible, the following implementation is geared for the real world. In order to execute it, just choose an actual WSDL URL and construct the input XML files for the functions properly, this can also be done in C but requires libraries like xerces unless you want to really construct the XML from scratch.
<lang C>
- include <curl/curl.h>
- include <string.h>
- include <stdio.h>
size_t write_data(void *ptr, size_t size, size_t nmeb, void *stream){
return fwrite(ptr,size,nmeb,stream);
}
size_t read_data(void *ptr, size_t size, size_t nmeb, void *stream){
return fread(ptr,size,nmeb,stream);
}
void callSOAP(char* URL, char * inFile, char * outFile) {
FILE * rfp = fopen(inFile, "r"); if(!rfp) perror("Read File Open:");
FILE * wfp = fopen(outFile, "w+"); if(!wfp) perror("Write File Open:");
struct curl_slist *header = NULL;
header = curl_slist_append (header, "Content-Type:text/xml"); header = curl_slist_append (header, "SOAPAction: rsc"); header = curl_slist_append (header, "Transfer-Encoding: chunked"); header = curl_slist_append (header, "Expect:");
CURL *curl;
curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, URL); curl_easy_setopt(curl, CURLOPT_POST, 1L); curl_easy_setopt(curl, CURLOPT_READFUNCTION, read_data); curl_easy_setopt(curl, CURLOPT_READDATA, rfp); curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_data); curl_easy_setopt(curl, CURLOPT_WRITEDATA, wfp); curl_easy_setopt(curl, CURLOPT_HTTPHEADER, header); curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE_LARGE, (curl_off_t)-1); curl_easy_setopt(curl, CURLOPT_VERBOSE,1L); curl_easy_perform(curl);
curl_easy_cleanup(curl); }
}
int main(int argC,char* argV[]) { if(argC!=4) printf("Usage : %s <URL of WSDL> <Input file path> <Output File Path>",argV[0]); else callSOAP(argV[1],argV[2],argV[3]); return 0; } </lang> Input XML for soapFunc() <lang XML> <?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:dom="http://example.com/soap/wsdl">
<soapenv:Header/> <soapenv:Body> <dom:soapFunc soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> </soapenv:Body>
</soapenv:Envelope> </lang> Input XML for anotherSoapFunc() <lang XML> <?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:dom="http://example.com/soap/wsdl">
<soapenv:Header/> <soapenv:Body> <dom:anotherSoapFunc soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> </soapenv:Body>
</soapenv:Envelope> </lang>
Clojure
<lang clojure>(require '[clj-soap.core :as soap])
(let [client (soap/client-fn "http://example.com/soap/wsdl")]
(client :soapFunc) (client :anotherSoapFunc))</lang>
ColdFusion
<lang cfm><cfset client = createObject("webservice","http://example.com/soap/wsdl")> <cfset result = client.soapFunc("hello")> <cfset result = client.anotherSoapFunc(34234)></lang>
F#
The availability of functions and the type of parameters is checked at compile time. The development environment supports auto-completion and parameter information just like for regular types.
<lang fsharp>open Microsoft.FSharp.Data.TypeProviders
type Wsdl = WsdlService<"http://example.com/soap/wsdl"> let result = Wsdl.soapFunc("hello") let result2 = Wsdl.anotherSoapFunc(34234)</lang>
Icon and Unicon
provides the Soap package.
This code uses Unicon features not available in Icon. <lang unicon>import soap
procedure main(A)
soap := SoapClient(A[1] | "http://example.com/soap/wsdl") # Allow override of default write("soapFunc: ",soap.call("soapFunc")) write("anotherSoapFunc: ",soap.call("anotherSoapFunc"))
end</lang>
A matching SOAP server can be implemented as:
<lang unicon>import soap
procedure main()
server := SoapServer("http://example.com/soap/wsdl") server.addService("soapFunc", soapFunc) server.addService("anotherSoapFunc", anotherSoapFunc) msg := server.handleRequest() write(msg) exit(0)
end
procedure soapFunc(A[])
every (s := " ") ||:= (!A || " ") return "Hello" || s[1:-1]
end
procedure anotherSoapFunc(A[])
every (s := " ") ||:= (!A || " ") return "Goodbye" || s[1:-1]
end</lang>
Kotlin
Assuming that libcurl is already installed on your system in the default location(s), you first need to build libcurl.klib using the following .def file and the cinterop tool:
// libcurl.def headers = /usr/include/curl/curl.h linkerOpts.linux = -L/usr/lib/x86_64-linux-gnu -lcurl
Next, you need to compile the following Kotlin program, linking against libcurl.klib. <lang scala>// Kotlin Native v0.6
import kotlinx.cinterop.* import platform.posix.* import libcurl.*
fun writeData(ptr: COpaquePointer?, size: size_t, nmeb: size_t, stream: COpaquePointer?)
= fwrite(ptr, size, nmeb, stream?.reinterpret<FILE>())
fun readData(ptr: COpaquePointer?, size: size_t, nmeb: size_t, stream: COpaquePointer?)
= fread(ptr, size, nmeb, stream?.reinterpret<FILE>())
fun callSOAP(url: String, inFile: String, outFile: String) {
val rfp = fopen(inFile, "r") if (rfp == null) { perror("Read File Open: ") exit(1) } val wfp = fopen(outFile, "w+") if (wfp == null) { perror("Write File Open: ") fclose(rfp) exit(1) }
var header: CPointer<curl_slist>? = null header = curl_slist_append (header, "Content-Type:text/xml") header = curl_slist_append (header, "SOAPAction: rsc") header = curl_slist_append (header, "Transfer-Encoding: chunked") header = curl_slist_append (header, "Expect:")
val curl = curl_easy_init() if (curl != null) { curl_easy_setopt(curl, CURLOPT_URL, url) curl_easy_setopt(curl, CURLOPT_POST, 1L) curl_easy_setopt(curl, CURLOPT_READFUNCTION, staticCFunction(::readData)) curl_easy_setopt(curl, CURLOPT_READDATA, rfp) curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, staticCFunction(::writeData)) curl_easy_setopt(curl, CURLOPT_WRITEDATA, wfp) curl_easy_setopt(curl, CURLOPT_HTTPHEADER, header) curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE_LARGE, -1L) curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L) curl_easy_perform(curl) curl_easy_cleanup(curl) }
curl_slist_free_all(header) fclose(rfp) fclose(wfp)
}
fun main(args: Array<String>) {
if (args.size != 3) { println("You need to pass exactly 3 command line arguments, namely :-") println(" <URL of WSDL> <Input file path> <Output File Path>") return } callSOAP(args[0], args[1], args[2])
}</lang> Finally, the resulting .kexe file should be executed passing it similar command line arguments to the C entry.
Mathematica
<lang Mathematica>InstallService["http://example.com/soap/wsdl"]; soapFunc["Hello"]; anotherSoapFunc[12345]; </lang>

response2 = soap.anotherSoapFunc(:aNumber => 42) puts response2.anotherSoapFuncReturn</lang>
Smalltalk
(not sure about Pharo and VW)
(assuming that the open source SOAPSpray package has been loaded.) <lang smalltalk>| service client response1 response2 |
service := SprayWSDLService onUrl: 'http://example.com/soap/wsdl'.
client := service createClient. response1 := client send: 'soapFunc' withArguments:{ 'hello' }. response2 := client send: 'anotherSoapFunc' withArguments:{ 34234 }.</lang>
Tcl
Uses the tclws
package.
<lang Tcl>package require WS::Client
- Grok the service, and generate stubs
- WS::Client::GetAndParseWsdl http://example.com/soap/wsdl
- WS::Client::CreateStubs ExampleService ;# Assume that's the service name...
- Do the calls
set result1 [ExampleService::soapFunc "hello"] set result2 [ExampleService::anotherSoapFunc 34234]</lang>
Uniface
Assuming http://example.com/soap/wsdl has been imported into repository and, as result, exists a new component called "webservice"
<lang Uniface> variables
string result1, result2
endvariables
activate "webservice".soapFunc("hello", result1) activate "webservice".anotherSoapFunc(34234, result2) </lang>
VBScript
<lang vbscript>Dim client Dim result Set client = CreateObject("MSSOAP.SoapClient") client.MSSoapInit "http://example.com/soap/wsdl" result = client.soapFunc("hello") result = client.anotherSoapFunc(34234)</lang>
Visual Objects
<lang visobj>LOCAL oSoapClient AS OLEAUTOOBJECT LOCAL cUrl AS STRING LOCAL uResult AS USUAL oSoapClient := OLEAutoObject{"MSSOAP.SoapClient30"} cUrl := "http://example.com/soap/wsdl" IF oSoapClient:fInit
oSoapClient:mssoapinit(cUrl,"", "", "" ) uResult := oSoapClient:soapFunc("hello") uResult := oSoapClient:anotherSoapFunc(34234)
