我需要使用Python SOAPpy的模块来构建这个SOAP查询:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header>
<LicenseHeader xmlns="http://schemas.acme.eu/">
<LicenseKey>88888-88888-8888-8888-888888888888</LicenseKey>
</LicenseHeader>
</soap:Header>
<soap:Body>
<GetProductClassification xmlns="http://schemas.acme.eu/">
<GetProductClassificationRequest />
</GetProductClassification>
</soap:Body>
</soap:Envelope>
所以我用这个代码:
from SOAPpy import WSDL
wsdlFile = 'https://example.comt/1.0/service.asmx?wsdl'
server = WSDL.Proxy(wsdlFile)
result = server.GetProductClassification();
所产生的要求是:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
>
<SOAP-ENV:Body>
<GetProductClassification SOAP-ENC:root="1">
</GetProductClassification>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
当我把我的请求得到Object reference not set to an instance of an object.
我想这可能是因为我没有一个header
,在我的要求许可密钥部分。
如何修改我的代码添加header
部分与LicenseHeader
参数?
我不知道如何在SOAPpy的做到这一点,但我知道如何做到这一点的泡沫。 SUDS做同样的事情SOAPpy的,但它是新的,现在仍然支持。 我不认为是SOAPpy中不再支持。 下面展示的连接到WSDL和发送SOAP请求的代码:
class MySudsClass():
def sudsFunction(self):
url = "http://10.10.10.10/mywsdl.wsdl"
# connects to WSDL file and stores location in variable 'client'
client = Client(url)
#I have no address set in the wsdl to the camera I connect to so I set it's location here
client.options.location = 'http:/10.10.10.11'
# Create 'xml_value' object to pass as an argument using the 'factory' namespace
xml_value = client.factory.create('some_value_in_your_xml_body')
#This send the SOAP request.
client.service.WSDLFunction(xml_value)
将这个脚本您发送SOAP请求之前,它会添加任何你想要的标题。
# Namespaces to be added to XML sent
wsa_ns = ('wsa', 'http://schemas.xmlsoap.org/ws/2004/08/addressing')
wsdp_ns = ('http://schemas.xmlsoap.orf/ws/2006/02/devprof')
# Field information for extra XML headers
message = 'mymessage'
address_txt = 'myheader_information'
# Soapheaders to be added to the XML code sent
# addPrefix allow's you to addc a extra namespace. If not needed remove it.
message_header = Element('MessageID', ns=wsa_ns).setText(message)
address_header = Element('Address', ns=wsa_ns).setText(address_txt).addPrefix(p='wsdp', u=wsdp_ns)
header_list = [message_header, address_header]
# Soapheaders being added to suds command
client.set_options(soapheaders=header_list)
这将允许您在WSA encding,使XML理解补充:
# Attribute to be added to the headers to make sure camera verifies information as correct
mustAttribute = Attribute('SOAP-ENV:mustUnderstand', 'true')
for x in header_list:
x.append(mustAttribute)
如果您使用的东西,这样你就可以添加任何头,命名空间等等。我已经使用这个它完美地工作。
要在SUDS添加许可证头添加:
license_key = Element('LicenseKey', ns=some_namespace).setText('88888-88888-8888-8888-888888888888')
license_header = Element('LicenseHeader', ns=some_namespace).insert(license_key)
license_attribute = Attribute(xmlns, "http://schemas.acme.eu/")
license_header.append(license_attribute)
