Node.js请求对象文档？

Ben*_*ins 74 documentation request node.js

这是一个非常直截了当的问题,但我在谷歌上找不到任何东西.我正在寻找有关Node.js的创建服务器函数中的请求参数的文档,但我找不到任何东西.

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,即对象是循环的并且程序停止.我见过不同的东西request.url,或者request.body,是否有一个记录所有请求函数和参数的页面？它似乎很容易找到,我似乎无法找到它.

我再次尝试了,结果只是console.log(request)写出了请求中的所有数据.这里仅作为参考:

我不确定这是否是一个正确的回复,因为它对我来说似乎很简单,但你看看 http://nodejs.org/api/http.html#http_http_incomingmessage吗？

请求是上述对象的实例.顺便说一句,如果你真的想用"暴力"来看看那个对象里面有什么东西,你就不应该解析它,因为它根本不是一个JSON字符串,而是做类似的事情:

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

希望能帮助到你.

更好的是,要查看任何对象内部的内容,请使用util.inspect().Util是核心模块; 你可以简单地`var util = require('util');`和`util.inspect(obj)`.`JSON.stringify()`的一个基本问题是,如果存在循环引用,它会抱怨. (4认同)

再加上,作为Node.js中的一个相对新手,我发现每个框架都有自己的"请求"对象实现令人困惑.

例如,

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

和

Hapi:http://spumko.github.io/resource/api/#request-object(只是要注意原始请求对象在request.raw.req中仍然可用)

有些库假设存在Express'"req.param"方法,并且在非Express项目中使用时会失败.

我同意Delio,Request对象的类型是IncomingMessage对象,它由http.ClientRequest创建.
