Question

这是我尝试使用的代码：

import os
import socket
import httplib

packet='''
<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:xsd="http://www.w3.org/2001/XMLSchema"xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
 <soap12:Body>
  <GetCitiesByCountry xmlns="http://www.webserviceX.NET">
   <CountryName>India</CountryName>
  </GetCitiesByCountry>
 </soap12:Body>
</soap12:Envelope>'''
lent=len(packet)
msg="""
POST "www.webservicex.net/globalweather.asmx" HTTP/1.1
Host: www.webservicex.net
Content-Type: application/soap+xml; charset=utf-8
Content-Length: {length}
SOAPAction:"http://www.webserviceX.NET/GetCitiesByCountry"
Connection: Keep-Alive
{xml}""".format(length=lent,xml=packet)

client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client.connect( ("www.webservicex.net",80) )
if bytes != str: # Testing if is python2 or python3
    msg = bytes(msg, 'utf-8')
client.send(msg)
client.settimeout(10)
print(client.type)
res=client.recv(4096)
print(res)
#res = res.replace("<","&lt;") -- only for stack overflow post
#res = res.replace(">","&gt;") -- only for stack overflow post

输出结果为：

HTTP/1.1 400 Bad Request

有什么想法吗？

您应该使用suds来使用SOAP Web服务。

编辑：示例

import suds
import suds.transport
from suds.transport.http import HttpAuthenticated


class MyException(Exception):
    pass


service_url = "http://my/service/url"

获取可用服务：

try:
    transport = HttpAuthenticated(username='elmer', password='fudd')
    wsdl = suds.client.Client(service_url, faults=False, transport=transport)

except IOError as exc:
    fmt = "Can initialize my service: {reason}"
    raise MyException(fmt.format(reason=exc))

except suds.transport.TransportError as exc:
    fmt = "HTTP error -- Is it a bad URL: {service_url}? {reason}"
    raise MyException(fmt.format(service_url=service_url, raison=exc))

运行给定服务（此处，其名称为RunScript）：

# add required options in headers
http_headers = {'sessionID': 1}
wsdl.set_options(soapheaders=http_headers)

params = {"scriptLanguage": "javascript", "scriptFile": "...",
          "scriptArgs": [{"name": "...", "value": "..."}]}

try:
    exit_code, response = wsdl.service.RunScript([params])
    # ...
except suds.MethodNotFound as reason:
    raise MyException("No method found: {reason}".format(reason=reason))
except suds.WebFault as reason:
    raise MyException("Error running the script: {reason}".format(reason=reason))
except Exception as reason:
    err_msg = "{0}".format(reason)
    if err_msg == "timed out":
        raise MyException("Timeout: {reason}".format(reason=reason))
    raise

当然，这里不需要使用错误管理器。但我举一个例子。 “超时”的最后一个是我用来检测应用程序超时的一种黑客攻击。

使用socket给出错误的免费SOAP服务的Python客户端？
