jsonrpc

A JSON-RPC 2.0 implementation for Python (Python 3 not supported yet)

Getting Started

Installing the librarary:

% python setup.py install

Alternatively, one can use the following commands from the directory which contains the ‘setup.py’ file.

Start the Server:

% python -m jsonrpc.example_server
Listening on port 8007...

Start the Client:

Python 2.7: python -m jsonrpc <host name>

Python 2.6: python -m jsonrpc.__main__ <host name>

>>> server.add(1, 2)
3

>>> server.subtract(3,2)
1

# Exceptions
>>> server.add(1, '2')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "jsonrpc/proxy.py", line 182, in __call__
    raise JSONRPCException(resp['error'])
jsonrpc.proxy.JSONRPCException: unsupported operand type(s) for +: 'int' and 'unicode'


>>> server.batch_call( dict(add=( (1,2), {} ), subtract=( (3,2), {} )) )
[(3, None), (1, None)] # the pattern is (result, error)

# batch calls can also be done with an iterable, if you want
# to have more than one call to the same method
>>> server.batch_call( [('add', ((1, 2), {})), ('subtract', ((3, 2), {}))] )
[(3, None), (1, None)]

# Exceptions in batch calls
>>> server.batch_call( dict(add=( (1,2), {} ), subtract=( (3,'2'), {} )) )
[(3, None), (None, {u'message': u"unsupported operand type(s) for -: 'int' 
  and 'unicode'", u'code': 0, u'data': [u"unsupported operand type(s) for -: 
  'int' and 'unicode'"]})]
