I am wondering if I co开发者_如何学运维uld use simply use HTTP POST Requests in order to implement a SOAP API.
If so how should I format and treat the requests?
Yep, I have done this in certain cases where SOAPpy did not work with a given schema. This should get you started.
import httplib
from xml.dom import minidom
http.request("POST", "/path/to/my/webservice", body=xml, headers = {
"Host": "myservername",
"Content-Type": "text/xml; charset=UTF-8",
"Content-Length": len(xml)
})
print minidom.parseString(http.getresponse().read())
For the content string, I would use SoapUI to make the requests manually, and then mimic the XML.
Yes, see http://www.w3schools.com/SOAP/soap_httpbinding.asp
A SOAP method is an HTTP request/response that complies with the SOAP encoding rules.
HTTP + XML = SOAP
A SOAP request could be an HTTP POST or an HTTP GET request.
You'll sometimes find other transport mechanisms used for quality of service reasons, for instance using a messaging framework.
I found a great example of this in the simple-salesforce package. The code is in login.py
and pasted below
soap_url = 'https://{domain}.salesforce.com/services/Soap/u/{sf_version}'
domain = 'test' if sandbox else 'login'
soap_url = soap_url.format(domain=domain, sf_version=sf_version)
username = escape(username)
password = escape(password)
# Check if token authentication is used
if 'security_token' in kwargs:
security_token = kwargs['security_token']
# Security Token Soap request body
login_soap_request_body = """<?xml version="1.0" encoding="utf-8" ?>
<env:Envelope
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
<env:Body>
<n1:login xmlns:n1="urn:partner.soap.sforce.com">
<n1:username>{username}</n1:username>
<n1:password>{password}{token}</n1:password>
</n1:login>
</env:Body>
</env:Envelope>""".format(username=username, password=password, token=security_token)
# Check if IP Filtering is used in cojuction with organizationId
elif 'organizationId' in kwargs:
organizationId = kwargs['organizationId']
# IP Filtering Login Soap request body
login_soap_request_body = """<?xml version="1.0" encoding="utf-8" ?>
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:urn="urn:partner.soap.sforce.com">
<soapenv:Header>
<urn:CallOptions>
<urn:client>RestForce</urn:client>
<urn:defaultNamespace>sf</urn:defaultNamespace>
</urn:CallOptions>
<urn:LoginScopeHeader>
<urn:organizationId>{organizationId}</urn:organizationId>
</urn:LoginScopeHeader>
</soapenv:Header>
<soapenv:Body>
<urn:login>
<urn:username>{username}</urn:username>
<urn:password>{password}</urn:password>
</urn:login>
</soapenv:Body>
</soapenv:Envelope>""".format(
username=username, password=password, organizationId=organizationId)
else:
except_code = 'INVALID AUTH'
except_msg = 'You must submit either a security token or organizationId for authentication'
raise SalesforceAuthenticationFailed(except_code, except_msg)
login_soap_request_headers = {
'content-type': 'text/xml',
'charset': 'UTF-8',
'SOAPAction': 'login'
}
response = requests.post(soap_url,
login_soap_request_body,
headers=login_soap_request_headers,
proxies=kwargs.get('proxies', None))
