从http请求路由时，Express.io无法发出事件。

Question

Here  i use those codes:
// Initial web request.
app.get('/hello', function(req, res) {
    // Forward to an io route.
    req.io.route('hello')
})

app.io.route('hello', function(req) {
    //Here use emit
    req.io.emit("world","world");
})

它报告的错误如下：

TypeError: Object #<Object> has no method 'emit'

req.io.respond没事。

广播也有一些problem.It可以播放，但它不停止后广播。它运行了很长一段时间，然后不返回任何内容，也不返回错误消息。

我的代码是

// Initial web request.
app.get('/hello', function(req, res) {
    // Forward to an io route.
    req.io.route('hello')
})

// Forward io route to another io route.
app.io.route('hello', function(req) {
    req.io.broadcast("world","world");
})

Answer 1

从堆栈跟踪来看，您发布的代码看起来并不是实际的代码。

但除此之外:据我所理解的express.io，当您将HTTP请求转发给io路由时，io路由应该总是用respond发送回响应；否则，HTTP请求将停止。

所以试试这个：

app.get('/hello', function(req, res) {
  req.io.route('hello');
});

app.io.route('hello', function(req) {
  // broadcast first...
  req.io.broadcast("world","world");
  // ...then send back an empty response
  req.io.respond();
});

为了确保：req.io.broadcast不会将消息发送回发起请求的客户端。如果您想要这样做，请使用app.io.broadcast (见文档)。

答复率只有50% )：

.respond使用您的参数“直接”发出，例如：

req.io.respond({hello: 'world'})
