AuthServiceProxy has the following improvements over python-jsonrpc's |
||||
ServiceProxy class: |
||||
|
||||
- HTTP connections persist for the life of the AuthServiceProxy object |
||||
(if server supports HTTP/1.1) |
||||
- sends protocol 'version', per JSON-RPC 1.1 |
||||
- sends proper, incrementing 'id' |
||||
- sends Basic HTTP authentication headers |
||||
- parses all JSON numbers that look like floats as Decimal |
||||
- uses standard Python json lib |
||||
