Python JSON-RPC Library Client Server - Simple To Use Python JSONRPC-Library
Project description
Installation
pip install bunch pip install python-jsonrpc
Library Usage Example
#!/usr/bin/env python
# coding: utf-8
import pyjsonrpc
def add(a, b):
"""Test function"""
return a + b
# 1. Initialize JSON-RPC class with JSON-RPC method(s)
rpc = pyjsonrpc.JsonRpc(methods = {"add": add})
# 2. Create JSON-RPC string with parameters (= request string)
request_json = pyjsonrpc.create_request_json("add", 1, 2)
# request_json = '{"method": "add", "params": [1, 2], "id": "...", "jsonrpc": "2.0"}'
# 3. Call the JSON-RPC function and get back the JSON-RPC result (= response string)
response_json = rpc.call(request_json)
# response_json = '{"result": 3, "id": "...", "jsonrpc": "2.0"}'
# 4. Convert JSON-RPC string to Python objects
response = pyjsonrpc.parse_response_json(response_json)
# 5. Print result or error
if response.error:
print "Error:", response.error.code, response.error.message
else:
print "Result:", response.result
HTTP Client Example
#!/usr/bin/env python
# coding: utf-8
import pyjsonrpc
http_client = pyjsonrpc.HttpClient(
url = "http://example.com/jsonrpc",
username = "Username",
password = "Password"
)
print http_client.call("add", 1, 2)
# Result: 3
# It is also possible to use the *method* name as *attribute* name.
print http_client.add(1, 2)
# Result: 3
HTTP Server Example
#!/usr/bin/env python
# coding: utf-8
import pyjsonrpc
def add(a, b):
"""Test function"""
return a + b
class RequestHandler(pyjsonrpc.HttpRequestHandler):
# Register public JSON-RPC methods
methods = {
"add": add
}
# Threading HTTP-Server
http_server = pyjsonrpc.ThreadingHttpServer(
server_address = ('localhost', 8080),
RequestHandlerClass = RequestHandler
)
print "Starting HTTP server ..."
print "URL: http://localhost:8080"
http_server.serve_forever()
CGI Example
#!/usr/bin/env python
# coding: utf-8
import pyjsonrpc
def add(a, b):
"""Test function"""
return a + b
# Handles the JSON-RPC request and gets back the result to STDOUT
pyjsonrpc.handle_cgi_request(methods = dict(add = add))
