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
|
