Js 请求对象文档?

这是一个非常直接的问题,但我在谷歌上没有找到任何东西。我正在 Node.js 的 create server 函数中寻找有关请求参数的文档,但是我还没有找到任何东西。

http.createServer(function(request, response){
console.log(JSON.stringify(request));
});

使用 JSON.stringify ()进行调试会产生一个错误,即对象是循环的,程序停止。我已经看到了不同的东西,比如 request.urlrequest.body,但是是否有一个页面记录了所有的请求函数和参数?看起来应该很容易找到,但我就是找不到。

我又试了一次,结果发现只需执行 console.log(request)即可写出请求中的所有数据。以下仅供参考:

I'm not sure if this is a correct reply as it seems straightforward to me, but did you have a look at http://nodejs.org/api/http.html#http_http_incomingmessage?

Request is instance of the above object. By the way, if you really want to see what's inside that object with "brute force," you should not parse it, as it will not be a JSON string at all, but instead do something like:

for (i in request) {
//Your code here
}

Hope it helps.

I agree with Delio, the Request object is of type IncomingMessage object, which is created by http.ClientRequest.

Just to add on, as a relative newbie in Node.js, I find it confusing that each framework has its own implementation of a "request" object.

For example,

Express: http://expressjs.com/api.html#req.param

and

Hapi: http://spumko.github.io/resource/api/#request-object (just to note that the raw request object is still available in request.raw.req)

Some libraries assume the presence of Express' "req.param" method, and fail when used in non-Express projects.
