node.js - curl成功浏览器连接不上

Question

我在对着Nodejs高级教程学习，有一节是向客户端传送子进程输出的例子。

var spawn=require('child_process').spawn;
require('http').createServer(function(req,res){
    var child=spawn('tail',['-f','/var/log/system.log']);
    child.stdout.pipe(res);
    res.on('end',function(){
        child.kill();
    });
}).listen(4007);

我是在windows系统中安装的babun，然后使用curl命令成功看到结果：

但是在服务器上打开就一直失败...

真心求教。。。强迫症的我一直在研究中.....

EDGE11和ff可以。。。不理解 chrome的安全机制吗（我有两个chrome，都无效）

Answer 1

Didn’t you notice that curl never ends? This is not normal.

The main reason is that your child process uses the tail -f command, so that the end time of res will not be triggered, and this request will never end.

You can try using the cat command

Answer 2

You may be using fake chrome. . This is normal for me.

But the only problem is that it keeps requesting data. . It should be that the tail command has not ended.
