XML-RPC Javascript 不支持的方法（“选项”）

发布于 2024-09-10 08:32:47 字数 679 浏览 4 评论 0原文

我们有一个 XML-RPC 服务器（用 python 实现），我正在尝试编写一个简单的 javascript 应用程序来向它发送调用。无论我创建什么库，我似乎总是会遇到错误：

Unsupported method ('OPTIONS')

可以公平地说，我不理解 XML-RPC 和 HTTP 的底层协议，而我应该理解。但我所知道的是，这在Python中有效：

client = xmlrpclib.ServerProxy('http://localhost:2002')
client.T.run_process()

但以下JavaScript无效：

var client = new xmlrpc_client("", "localhost", 2002, "http")
var msg = new xmlrpcmsg("T.run_process()", {})
lert(client.send(msg));

我正在使用这个 JavaScript 库。但似乎无论我使用什么库，我都会遇到相同的错误，所以我猜我们的服务器不符合 python 不介意的某些协议，对吗？

We've got an XML-RPC server (implemented in python), and I'm trying to write a simple javascript app to send calls to it. Whatever library I make I seem to always get the error:

Unsupported method ('OPTIONS')

It's fair to say I don't understand the underlying protocols for XML-RPC and HTTP as well as I should. But what I do know is that this works in python:

client = xmlrpclib.ServerProxy('http://localhost:2002')
client.T.run_process()

But the following javascript doesn't:

var client = new xmlrpc_client("", "localhost", 2002, "http")
var msg = new xmlrpcmsg("T.run_process()", {})
lert(client.send(msg));

I'm using this javascript library. But it seems I get the same error no matter what library I use, so I guess our server isn't conforming to some protocol that python doesn't mind about, is this right?

使用 python 中的标准 SimpleXMLRPCServer，将以下内容添加到 RequestHandler 方法似乎对我有用：

class RequestHandler(SimpleXMLRPCRequestHandler):
    rpc_paths = ('/RPC2',)

    def do_OPTIONS(self):
        self.send_response(200)
        self.end_headers()

    # Add these headers to all responses
    def end_headers(self):
        self.send_header("Access-Control-Allow-Headers", 
                         "Origin, X-Requested-With, Content-Type, Accept")
        self.send_header("Access-Control-Allow-Origin", "*")
        SimpleXMLRPCRequestHandler.end_headers(self)

Using the standard SimpleXMLRPCServer from python, adding the following to the RequestHandler methods seemed to work for me:

class RequestHandler(SimpleXMLRPCRequestHandler):
    rpc_paths = ('/RPC2',)

    def do_OPTIONS(self):
        self.send_response(200)
        self.end_headers()

    # Add these headers to all responses
    def end_headers(self):
        self.send_header("Access-Control-Allow-Headers", 
                         "Origin, X-Requested-With, Content-Type, Accept")
        self.send_header("Access-Control-Allow-Origin", "*")
        SimpleXMLRPCRequestHandler.end_headers(self)

这可能是 CORS 的实际应用。

我最近正在与类似的事情作斗争。

问题是 python 的 XMLRPC 服务器在 XML-RPC 请求中不包含 CORS 标头（也不响应 HTTP OPTIONS 请求）。

我使用 Twisted 来提供 XMLRPC 资源，并解决了向 XMLRPC 请求添加 OPTIONS 响应和标头的问题。

我的代码看起来像这样：

from twisted.web.xmlrpc import withRequest

class MyResourceEndpoint(xmlrpc.XMLRPC):
    def render_OPTIONS(self, request):    
        request.setHeader('Access-Control-Allow-Origin', '*')
        request.setHeader('Access-Control-Allow-Methods', 'POST, GET, OPTIONS')        
        request.setHeader('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept')
        return ""

    @withRequest
    def xmlrpc_my_method(self, request, my_params):
        request.setHeader('Access-Control-Allow-Origin', '*')
        request.setHeader('Access-Control-Allow-Methods', 'POST, GET, OPTIONS')        
        request.setHeader('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept')
        return "Whatever your method do"

root = resource.Resource()
root.putChild('', MyResourceEndpoint())
reactor.listenTCP(9090, server.Site(root))

reactor.run()

I was fighting against something similar recently.

The problem is that python's XMLRPC server does not include CORS headers (nor respond HTTP OPTIONS request) in the XML-RPC request.

I'm using Twisted to serve the XMLRPC Resource, and solved that adding the OPTIONS response and the headers to the XMLRPC request.

My code looks something like:

from twisted.web.xmlrpc import withRequest

class MyResourceEndpoint(xmlrpc.XMLRPC):
    def render_OPTIONS(self, request):    
        request.setHeader('Access-Control-Allow-Origin', '*')
        request.setHeader('Access-Control-Allow-Methods', 'POST, GET, OPTIONS')        
        request.setHeader('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept')
        return ""

    @withRequest
    def xmlrpc_my_method(self, request, my_params):
        request.setHeader('Access-Control-Allow-Origin', '*')
        request.setHeader('Access-Control-Allow-Methods', 'POST, GET, OPTIONS')        
        request.setHeader('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept')
        return "Whatever your method do"

root = resource.Resource()
root.putChild('', MyResourceEndpoint())
reactor.listenTCP(9090, server.Site(root))

reactor.run()
