AuthServiceProxy is an improved version of python-jsonrpc. | ||
|
||
It includes the following generic improvements: | ||
|
||
- HTTP connections persist for the life of the AuthServiceProxy object | ||
- sends protocol 'version', per JSON-RPC 1.1 | ||
- sends proper, incrementing 'id' | ||
- uses standard Python json lib | ||
|
||
It also includes the following bitcoin-specific details: | ||
|
||
- sends Basic HTTP authentication headers | ||
- parses all JSON numbers that look like floats as Decimal | ||
|
||
Installation: | ||
|
||
- change the first line of setup.py to point to the directory of your installation of python 2.* | ||
- run setup.py | ||
|
||
Note: This will only install bitcoinrpc. If you also want to install jsonrpc to preserve | ||
backwards compatibility, you have to replace 'bitcoinrpc' with 'jsonrpc' in setup.py and run it again. |

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 | ||
