对我来说,这似乎是服务器以ascii形式编写响应,而不是在发送之前先将其压缩.

下面是我为编写这些结果而编写的示例.根据我的阅读,只要我设置’浏览器客户端gzip’,我的响应应该被发送gzip.如果它们不是我怎么做的,如果我是如何从服务器的调试信息中知道它们实际上是压缩响应.

当我启动服务器时,我在BASH中使用以下命令：

$NODE_ENV =生产节点app.js

var express = require('express'),http    = require('http');

var app     = express(),server  = http.createServer(app),io      = require('socket.io').listen(server);

io.configure('production',function() {
    io.enable('browser client minification');
    io.enable('browser client etag');
    io.enable('browser client gzip');
    io.set('log level',3);
});

app.use(express.logger('dev'));

app.get('/',function(req,res) {
    res.send(
    "<script src='/socket.io/socket.io.js'></script>\n"+
    "<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js'></script>\n"+
    "<script>\n"+
    "var socket=io.connect('http://127.0.0.1:3000');\n"+
    "socket.on('message',function(data) {\n"+
    "   $(\"h2\").text(data);\n"+
    "});\n"+
    "</script>\n"+
    "<h1>"+process.env.NODE_ENV+"</h1>\n"+
    "<h2></h2>\n"
    );
});

server.listen('3000');

io.sockets.on('connection',function(webSocket) {
    function whileLoop() {
        setTimeout(function() {
                var epoch = (new Date).getTime();
                var jsonData = "{\"result\":"+epoch+"}";
                webSocket.send(jsonData);
            whileLoop();
        },1000);
    }
    whileLoop();
});
