Angularjs, sockjs, angular-sockjs注入不起作用
angularjs, sockjs, angular-sockjs injection not working
我正在尝试使用sockjs-client和cyclone,一个组件由bendrucker存在:https://github.com/bendrucker/angular-sockjs。所有这些技术的新手,我卡住了一个注射问题,当我试图使用组件从本德鲁克。我使用的是angular 1.2.19, angular-route 1.2.19,错误跟踪是:

脚本/控制器/main.js:

$sockets.open("http://ip_address:8888/query");

}

}
路由器机制工作了,现在所有的视图几乎都是空的。当我得到错误时正在加载索引。我正在使用的服务器,以防万一:
import sys
import os
import time
import sockjs.cyclone
from cyclone.web import RequestHandler, Application, StaticFileHandler
from twisted.internet.task import LoopingCall
from twisted.internet import reactor
from twisted.python import log
settings = {
"static_path": os.path.join(os.path.dirname(os.path.dirname(__file__)), "client")
}
class IndexHandler(RequestHandler):
""" Serve the chat html page """
def get(self):
self.render('../client/index.html')
class QueryConnection(sockjs.cyclone.SockJSConnection):
participants = set()
def __init__(self, session):
sockjs.cyclone.SockJSConnection.__init__(self, session)
lc = LoopingCall(self.newMessage)
lc.start(1)
def newMessage(self):
self.broadcast(self.participants, str(time.time()))
def connectionMade(self, info):
self.broadcast(self.participants, "Someone joined.")
self.participants.add(self)
def messageReceived(self, message):
self.broadcast(self.participants, message)
def connectionLost(self):
self.participants.remove(self)
self.broadcast(self.participants, "Someone left.")
if __name__ == "__main__":
def main():
QueryRouter = sockjs.cyclone.SockJSRouter(QueryConnection, '/query')
app = Application([
(r"/", IndexHandler),
(r"/(.*)", StaticFileHandler, dict(path=settings['static_path'])),
] + QueryRouter.urls, **settings)
reactor.listenTCP(8888, app)
reactor.run()
log.startLogging(sys.stdout)
main()
原来的问题是,只有核心服务在angular应该前缀'$',自定义模块不应该有'$',所以正确的方式在控制器。js是:
function ReceptorController($scope, sockets){
var conn = sockets({'url':'http://ip_address:8888/query'});
conn.setHandler('message', function(msg){
$scope.state = msg;
})
}
function ContactenosController($scope){
}
function BuscadorController($scope){
}
