Unknown error when submit a REST request to Liferay json API
- by r.rodriguez
I'm writing an script in Python to automatically update the structures in my Liferay portal and I want to do it via the json REST API.
I make a request to get an structure (method getStructure), and it worked.
But when I try to do an structure update in the portal it shows me the following error:
ValueError: Content-Length should be specified for iterable data of type class 'dict' {'serviceContext': "{'prueba'}", 'serviceClassName': 'com.liferay.portlet.journal.service.JournalStructureServiceUtil', 'name': 'FOO', 'xsd': '... THE XSD OBTAINED VIA JSON ...', 'serviceParameters': '[groupId,structureId,parentStructureId,name,description,xsd,serviceContext]', 'description': 'FOO Structure', 'serviceMethodName': 'updateStructure', 'groupId': '10133'}
What I'm doing is the next:
urllib.request.Request(url = URL, data = data_update, headers = headers)
URL is http://localhost:8080/tunnel-web/secure/json
The headers are configured with basic authentication (it works, it is tested with the getStructure method).
Data is:
data_update = { "serviceClassName" : "com.liferay.portlet.journal.service.JournalStructureServiceUtil", "serviceMethodName" : "updateStructure", "serviceParameters" : "[groupId,structureId,parentStructureId,name,description,xsd,serviceContext]", "groupId" : 10133, "name" : FOO, "description" : FOO Structure, "xsd" : ... THE XSD OBTAINED VIA JSON ..., "serviceContext" : "{}" }
Does anybody know the solution? Have I to specify the length for the dictionary and how? Or this is a bug?
