Soap Client using Suds

Question

Soap call in Python

Hi above is my previous question regarding soap. In there i am passing a 1D array. Now my problem is i need to pass the 2D array to the following Soap schema.

Request Schema

<?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:Body>
    <CalculateWeb2DObjectArray xmlns="http://tempuri.org/">
      <HCID>string</HCID>
      <jaggedobjDataMICRO>
        <ArrayOfAnyType>
          <anyType />
          <anyType />
        </ArrayOfAnyType>
        <ArrayOfAnyType>
          <anyType />
          <anyType />
        </ArrayOfAnyType>
      </jaggedobjDataMICRO>
      <numeratorID>int</numeratorID>
    </CalculateWeb2DObjectArray>
  </soap:Body>
</soap:Envelope>

Response Schema

 <?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:Body>
        <CalculateWeb2DObjectArrayResponse xmlns="http://tempuri.org/">
          <CalculateWeb2DObjectArrayResult>
            <ArrayOfAnyType>
              <anyType />
              <anyType />
            </ArrayOfAnyType>
            <ArrayOfAnyType>
              <anyType />
              <anyType />
            </ArrayOfAnyType>
          </CalculateWeb2DObjectArrayResult>
        </CalculateWeb2DObjectArrayResponse>
      </soap:Body>
    </soap:Envelope>

My Code

from suds.xsd.doctor import Import, ImportDoctor
from suds.client import Client

# enable logging to see transmitted XML
import logging
logging.basicConfig(level=logging.INFO)
logging.getLogger('suds.client').setLevel(logging.DEBUG)

# fix broken wsdl
# add <s:import namespace="http://www.w3.org/2001/XMLSchema"/> to the wsdl
imp = Import('http://www.w3.org/2001/XMLSchema',
             location='http://www.w3.org/2001/XMLSchema.xsd')
imp.filter.add('http://tempuri.org/')
wsdl_url = 'http://204.9.76.243/nuCast.DataFeedService/Service1.asmx?WSDL'
client = Client(wsdl_url, doctor=ImportDoctor(imp))

# make request
arrayofstring1 = client.factory.create('ArrayOfString')
arrayofstring1.string = [1,2]
arrayofstring2 = client.factory.create('ArrayOfString')
arrayofstring2.string = [5,6]
arrayofstring = client.factory.create('ArrayOfString')
arrayofstring.string = [arrayofstring1,arrayofstring2]


print client.service.CalculateWeb2DObjectArray(1073757, arrayofstring, 99)

But i got empty value in output.Plz help to solve this.

Thanks

You pass invalid arguments to CalculateWeb2DObjectArray() function.

To find out what type of arguments CalculateWeb2DObjectArray() accepts, you could add to your script:

print client

The output contains:

CalculateWeb2DObjectArray(xs:string HCID,
                          ArrayOfArrayOfAnyType jaggedobjDataMICRO,
                          xs:int numeratorID, )

So the second argument should be ArrayOfArrayOfAnyType, use client.factory to create it:

aoaoat = client.factory.create('ArrayOfArrayOfAnyType')

To find out how to populate aoaoat, just print it:

print aoaoat

The output:

(ArrayOfArrayOfAnyType){
  ArrayOfAnyType[] = <empty>
}

Repeating the same procedure for ArrayOfAnyType you get:

(ArrayOfAnyType){
  anyType[] = <empty>
}

Putting it all together:

aoaoat = client.factory.create('ArrayOfArrayOfAnyType')
lst = aoaoat.ArrayOfAnyType = []
for L in [[1,2], [5,6]]:
    aoat = client.factory.create('ArrayOfAnyType')
    aoat.anyType = L
    lst.append(aoat)
response = client.service.CalculateWeb2DObjectArray(1073757, aoaoat, 99)
print response
