如何在 python 中发送 xml-rpc 请求？

我只是想知道，如何在 python 中发送 xml-rpc 请求？我知道您可以使用 xmlrpclib，但是如何在 xml 中发送请求来访问函数？

我想查看 xml 响应。

所以基本上我想将以下内容作为我的请求发送到服务器：

<?xml version="1.0"?>
<methodCall>
  <methodName>print</methodName>
  <params>
    <param>
        <value><string>Hello World!</string></value>
    </param>
  </params>
</methodCall>

并获取响应

原文

I was just wondering, how would I be able to send a xml-rpc request in python? I know you can use xmlrpclib, but how do I send out a request in xml to access a function?

I would like to see the xml response.

So basically I would like to send the following as my request to the server:

<?xml version="1.0"?>
<methodCall>
  <methodName>print</methodName>
  <params>
    <param>
        <value><string>Hello World!</string></value>
    </param>
  </params>
</methodCall>

and get back the response

下面是一个简单的 Python 中的 XML-RPC 客户端：

import xmlrpclib

s = xmlrpclib.ServerProxy('http://localhost:8000')
print s.myfunction(2, 4)

与此服务器配合使用：

from SimpleXMLRPCServer import SimpleXMLRPCServer
from SimpleXMLRPCServer import SimpleXMLRPCRequestHandler

# Restrict to a particular path.
class RequestHandler(SimpleXMLRPCRequestHandler):
    rpc_paths = ('/RPC2',)

# Create server
server = SimpleXMLRPCServer(("localhost", 8000),
                            requestHandler=RequestHandler)

def myfunction(x, y):
    status = 1
    result = [5, 6, [4, 5]]
    return (status, result)
server.register_function(myfunction)

# Run the server's main loop
server.serve_forever()

要访问 xmlrpclib 的内部结构，即查看原始 XML 请求等，请查找 xmlrpclib.Transport< /code> 文档中的类。

Here's a simple XML-RPC client in Python:

import xmlrpclib

s = xmlrpclib.ServerProxy('http://localhost:8000')
print s.myfunction(2, 4)

Works with this server:

from SimpleXMLRPCServer import SimpleXMLRPCServer
from SimpleXMLRPCServer import SimpleXMLRPCRequestHandler

# Restrict to a particular path.
class RequestHandler(SimpleXMLRPCRequestHandler):
    rpc_paths = ('/RPC2',)

# Create server
server = SimpleXMLRPCServer(("localhost", 8000),
                            requestHandler=RequestHandler)

def myfunction(x, y):
    status = 1
    result = [5, 6, [4, 5]]
    return (status, result)
server.register_function(myfunction)

# Run the server's main loop
server.serve_forever()

To access the guts of xmlrpclib, i.e. looking at the raw XML requests and so on, look up the xmlrpclib.Transport class in the documentation.

我已将 xmlrpc.client 中的源代码削减到所需的最低限度发送 xml rpc 请求（因为我有兴趣尝试移植该功能）。它返回响应 XML。

服务器：

from xmlrpc.server import SimpleXMLRPCServer

def is_even(n):
    return n%2 == 0

server = SimpleXMLRPCServer(("localhost", 8000))
print("Listening on port 8000...")
server.register_function(is_even, "is_even")
server.serve_forever()

客户端：

import http.client

request_body = b"<?xml version='1.0'?>\n<methodCall>\n<methodName>is_even</methodName>\n<params>\n<param>\n<value><int>2</int></value>\n</param>\n</params>\n</methodCall>\n"

connection = http.client.HTTPConnection('localhost:8000')
connection.putrequest('POST', '/')
connection.putheader('Content-Type', 'text/xml')
connection.putheader('User-Agent', 'Python-xmlrpc/3.5')
connection.putheader("Content-Length", str(len(request_body)))
connection.endheaders(request_body)

print(connection.getresponse().read())

I have pared down the source code in xmlrpc.client to a minimum required to send a xml rpc request (as I was interested in trying to port the functionality). It returns the response XML.

Server:

from xmlrpc.server import SimpleXMLRPCServer

def is_even(n):
    return n%2 == 0

server = SimpleXMLRPCServer(("localhost", 8000))
print("Listening on port 8000...")
server.register_function(is_even, "is_even")
server.serve_forever()

Client:

import http.client

request_body = b"<?xml version='1.0'?>\n<methodCall>\n<methodName>is_even</methodName>\n<params>\n<param>\n<value><int>2</int></value>\n</param>\n</params>\n</methodCall>\n"

connection = http.client.HTTPConnection('localhost:8000')
connection.putrequest('POST', '/')
connection.putheader('Content-Type', 'text/xml')
connection.putheader('User-Agent', 'Python-xmlrpc/3.5')
connection.putheader("Content-Length", str(len(request_body)))
connection.endheaders(request_body)

print(connection.getresponse().read())
