我正在使用环回 2.0 和 socket.io 1.0.6。

我想使用环回身份验证方法对 socket.io 进行身份验证。

我找到了在loopback/lib/middleware/token.js. https://github.com/strongloop/loopback/blob/master/lib/middleware/token.js

然后我像下面这样写。

var loopback = require('loopback');
var ioapp = module.exports = socketio;

function socketio(server) {
  var io = require('socket.io')(server);

  // auth
  io.use(function(socket, next) {
    loopback.token()(socket.request, null, next);
  });

  // listeners
  ...

  return io;
};

但实际上它不起作用并导致这样的错误。

/Users/.../project_root/node_modules/loopback/lib/models/access-token.js:201
    id = req.param(params[i]);
             ^
TypeError: Object #<IncomingMessage> has no method 'param'

我想这是因为我将错误的对象类型传递给了loopback.token()方法。我应该怎么做？

loopback.token 是一个快速中间件，它期望第一个参数是一个快速请求。
