示例调用短信发送接口，java, XFire, SOAP WSDL, webservice

soap.py

#!/usr/bin/python
#
import logging
logging.basicConfig(level=logging.INFO)
 
from suds.client import Client
from suds.sax.element import Element
 
url = 'http://localhost:8080/SendSmsService?wsdl'
client = Client(url)
 
# custum soap headers for authentication
auth = Element('AuthenticationToken') 
system = Element('system').setText('SMS')
auth.append(system)
username = Element('username').setText('sms')
auth.append(username)
password = Element('password').setText('sms')
auth.append(password)
client.set_options(soapheaders=auth)
 
client.service.sendSms('13912345678', 'python soap client through java soap server')

Soaplib is an easy to use python library for publishing soap web services using WSDL 1.1 standard, and answering SOAP 1.1 requests. With a very small amount of code, soaplib allows you to write a useful web service and deploy it as a WSGI application. WSGI is a python web standard for writing portable, extendable web applications in python.

用soaplib实现webservice

PHP的soap扩展不支持自定义头的认证方式，不过可以通过自定义请求XML文件的方式来实现。以下文件需要PHP的soap扩展，请先安装后再运行。

soap.php

    $wsdl = 'http://localhost:8080/services/SendSmsService?wsdl';
    $client = new SoapClient($wsdl);
 
    $reqXml = <<<XML
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:ns0="http://sendSms.webservice.com" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header>
      <AuthenticationToken>
         <system>SMS</system>
         <username>sms</username>
         <password>sms</password>
      </AuthenticationToken>
   </SOAP-ENV:Header>
   <ns1:Body>
      <ns0:sendSms>
         <ns0:in0>%s</ns0:in0>
         <ns0:in1>%s</ns0:in1>
         <ns0:in2>1</ns0:in2>
      </ns0:sendSms>
   </ns1:Body>
</SOAP-ENV:Envelope>
XML;
 
    $req = sprintf($reqXml, '13912345678', 'php soap client through java soap server');
    $location = 'http://localhost:8080/services/SendSmsService';
    $action = 'sendSms';
 
    $result = $client->__doRequest($req, $location, $action, SOAP_1_1);
