使用python向ESB端点提交SOAP请求

Question

我需要从python向ESB端点发送某个请求。基本上，我需要的是从ESB调用服务，而不必首先访问app

请帮忙，如有需要，我可以进一步澄清。在

下面我附上了虚拟请求。在

你所需要的就是发出正确的http请求。方法之一是“做同样的事情”

了解http请求是如何发出的。在您的例子中，最简单的方法是使用SoapUI工具。它是一个测试SOAP服务的工具。特性之一是将其配置为在控制台中显示tcp流量的转储。您将能够看到原始格式的响应请求。（好东西http是文本格式）

正如我提到的，只需发出POST请求，将SOAPAction头附加到application/xml中。那是不够的。在

无法从WSOESB服务器提供的wsdl文件中获取SOAPAction头和URL。在

这是个草图，可能需要调整一下。它是以Python3为基础的。在

import urllib.request
import urllib

# 8280 default port if you didn't change configuration of esb server
# /services default path if you didn't change configuration of esb server
# YourServiceName - service name 

url = 'http://esb-server-host:8280/services/YourServiceName'
method='POST'

# default SOAPAction extected for CUSTOME ESB PROXY SERVICE

headers = {'SOAPAction':'urn:mediate', 'Content-Type':'application/xml'}

req = urllib.request.Request(url, headers = headers, method=method)
with urllib.request.urlopen(req) as response:
   data = response.read()
   print(data)
