在IBM i (OS/400)上使用Python调用Web服务

本示例代码演示如何在IBM i (OS/400)上使用Python调用Web服务，包括构建SOAP消息，发送请求和解析响应。Python是一种通用的高级编程语言，与IBM i (OS/400)兼容良好。

import os
import subprocess
import urllib.request
import xml.etree.ElementTree as ET

# 定义Web服务的URL和SOAP消息
url = "http://example.com/webservice"
soap_message = """<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://example.com/service">
   <soapenv:Header/>
   <soapenv:Body>
      <ser:operation>
         <ser:param1>value1</ser:param1>
         <ser:param2>value2</ser:param2>
      </ser:operation>
   </soapenv:Body>
</soapenv:Envelope>"""

# 发送SOAP请求并解析响应
req = urllib.request.Request(url, data=soap_message.encode('utf-8'), headers={'Content-Type': 'text/xml'})
response = urllib.request.urlopen(req).read()
xml_tree = ET.fromstring(response)

# 解析响应的值并输出
result = xml_tree.find('.//{http://example.com/service}result').text
print("Web service response: " + result)
