我正在尝试将json内容从url widh sendMessage发送到具有的客户端

def broadcast(self):
  response = urllib2.urlopen('http://localhost:8001/json?as_text=1')
  data = json.load(response)

  for c in self.clients:
     c.sendMessage(data)
我得到了错误

File "myServer.py", line 63, in broadcast
c.sendMessage(data)

sendMessage
接受字节字符串或unicode字符串,而不是字典。这是因为WebSocket是二进制数据和文本数据的传输。它不是结构化对象的传输

您可以发送字典的JSON编码形式,但不能发送字典本身:

def broadcast(self):
    response = urllib2.urlopen('http://localhost:8001/json?as_text=1')

    for c in self.clients:
        c.sendMessage(response)
但是请注意,您实际上需要使用
twisted.web.client
——而不是阻塞
urllib2

from twisted.internet import reactor
from twisted.web.client import Agent, readBody

agent = Agent(reactor)

def broadcast(self):
    getting = agent.request(
        b"GET", b"http://localhost:8001/json?as_text=1")
    getting.addCallback(readBody)

    def got(body):
        for c in self.clients:
            c.sendMessage(body)
    getting.addCallback(got)
    return getting

确切地同意让·保罗的建议。。特别是使用Twisted的异步Web客户端,而不是(阻止)Python内置的东西。我从Twisted.Web.client import readBody ImportError中得到错误:不能导入名称readBody
readBody
是在Twisted 13.1.0中引入的。您可能正在使用比该版本更旧的Twisted。如果可以,请升级。否则,您可能希望使用(不太好的)twisted.web.client.getPage来代替。同意让·保罗的建议。。特别是使用Twisted的异步Web客户端,而不是(阻止)Python内置的东西。我从Twisted.Web.client import readBody ImportError中得到错误:不能导入名称readBody
