推荐答案

更简单的方法是挂接console.log并像往常一样调用console.log.

More simple way is hook console.log and call console.log as usually.

var util = require('util');
var JFile = require("jfile");
var nxFile = new JFile('/var/log/nginx/access.log');
...
process.stdout.write = (function(write) {   
    return function(text, encoding, fd) {
        write.apply(process.stdout, arguments); // write to console
        nxFile.text += util.format.apply(process.stdout, arguments) + '\n'; // write to nginx
     } 
 })(process.stdout.write);

还可以通过在上面的代码中将stdout更改为strerr来定义console.error的钩子.

Also you can define hook to console.error by change stdout to strerr in code above.

P.S.我没有Nginx来验证代码.所以代码可能包含错误:)

P.S. I don't have nginx to verify code. So code can contains errors :)
