python suds XML

Question

錯誤我嘗試了幾個小時從Soap Webservice接收數據。

這是我的代碼：

from suds.client import Client 
from suds import WebFault 

WSDL_URL = 'gatewaywebservice.asmx?wsdl' 
client = Client(WSDL_URL) 

checkIfExists = client.factory.create('checkIfExists') 
checkIfExists.SessionID = '' 
checkIfExists.UserID = 'ttester@email.com' 
try: 
    response = client.service.CustomerService(checkIfExists) 
    #print response 
    if response.Error: 
     print response.Error 
    else: 
     pass 
except WebFault, e: 
    print e 
print client.last_sent() 
print client.last_received() 

這是我送：

<SOAP-ENV:Envelope xmlns:ns0="asdf"            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/> 
    <ns1:Body> 
     <ns0:CustomerService> 
     <ns0:CustomerService> 
      <ns0:SessionID></ns0:SessionID> 
      <ns0:UserID>ttester@email.com</ns0:UserID> 
     </ns0:CustomerService> 
     </ns0:CustomerService> 
    </ns1:Body> 
</SOAP-ENV:Envelope> 

，這就是網絡服務器期待：

<?xml version="1.0" encoding="UTF-8"?> 
<GATEWAY xmlns="urn:Software-com:Gateway:v7-00"> 
<CustomerService> 
    <checkIfExists> 
     <SessionID/> 
     <UserID>test</UserID> 
    </checkIfExists> 
</CustomerService> 
</GATEWAY> 

我如何更新我的代碼發送有效的請求？

在此先感謝

您可以實現無泡沫插件在發送前修改XML。

在<SOAP-ENV:Envelope>標籤下面的示例進行了修改以符合網絡服務器的期望：

from suds.client import Client 
from suds.plugin import MessagePlugin 

class MyPlugin(MessagePlugin): 
    def marshalled(self, context): 
     envelope = context.envelope 
     envelope.name = 'GATEWAY' 
     envelope.setPrefix(None) 
     envelope.nsprefixes = {'xmlns' : 'urn:Software-com:Gateway:v7-00'} 
     # and so on... 
     # envelope[0] is the Header tag, envelope[1] the Body tag 
     # you can use "print context.envelope" to view the modified XML 

client = Client(WSDL_URL, plugins=[MyPlugin()]) 

你必須完成marshalled方法完全轉換XML。但在這之前，請檢查您是否擁有正確的WSDL文件，正如@Martijn Pieters所說。
