这是一个非常直截了当的问题,但我在Google上没有找到任何东西。我正在查找有关Node.js的create server函数中的request参数的文档,但我什么也找不到。
http.createServer(function(request, response){
console.log(JSON.stringify(request));
});
使用JSON.stringify()进行调试会给出一个错误,即对象是循环的,程序会停止。我见过不同的东西,比如request.url
或request.body
,但是有没有一个页面记录了所有的请求函数和参数?它看起来应该很容易找到,我就是找不到。
我又试了一次,结果发现只需执行console.log(request)
就可以写出请求中的所有数据。这里只是作为参考:

我不确定这是不是一个正确的回答,因为它在我看来是直截了当的,但是你有没有看过http://nodejs.org/api/http.html#http_http_incomingmessage
请求是上述对象的实例。顺便说一句,如果您真的想用“暴力”查看对象内部的内容,就不应该解析它,因为它根本不是一个JSON字符串,而应该这样做:
for (i in request) {
//Your code here
}
希望能有所帮助。

另外,作为Node.js中的新手,我发现每个框架都有自己的“请求”对象实现,这让我感到困惑。
例如,
Express:http://expressjs.com/api.html#req.param
和
Hapi:http://spumko.github.io/resource/api/#request-object (只需注意原始请求对象在request.raw.req中仍然可用)
一些库假定存在Express的"req.param“方法,在非Express项目中使用时会失败。

我同意Delio的观点,Request对象的类型是由http.ClientRequest创建的IncomingMessage对象。
