required requests

Start

DWR_HOST = 'https://www.example.com'
DWR_PARAMS = {'callCount':'1',
                'nextReverseAjaxIndex':'0',
                'c0-id':'0',
                'instanceId':'0'}
dwr = DWRClient(requests.Session(), DWR_HOST)
dwr.set_params(DWR_PARAMS)
dwr.set_page(DWR_HOST) #set page in dwr params

Initialize

initialize dwr.

get session id and set session.

  • script : script name default : __System
  • method : method name default : generateId
dwr.init()

Dump Parameters

convert dictionary params to dwr param string.

return dwr params string

  • params : dictionary ex) {‘callCount’:’1’}
dwr.dumps({'a':'1', 'b':'2' })

return string

a=1
b=2

Next Callflow

initialize batchId=0

reset session for another callflow

dwr.reset()

Set page

  • page : string ex) ’/path/name'
dwr.set_page('/path/name')

Request to DWR

  • script : script name
  • method : method name
  • args : arguments list with converting string: ex) [‘0’, ‘1’]
  • extra_params : add params which set using set_params() in this request
  • url : url (optional) default : /dwr/call/plaincall/script.method
dwr.request('dwrScript','method', ['1','2'])

return requests response

Call DWR

same request params

  • script : script name
  • method : method name
  • args : arguments list with converting string: ex) [‘0’, ‘1’]
  • extra_params : add params which set using set_params() in this request
  • url : url (optional) default : /dwr/call/plaincall/script.method
dwr.call('dwrScript','method', ['1','2'])

return dwr result parsing callback output
