Node.js请求对象文档?

标签: node.js documentation request

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,但我找不到任何内容。

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request.urlrequest.body之类的不同内容,但有一个页面记录了所有请求函数和参数吗?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,但你看看了吗? http://nodejs.org/api/http.html#http_http_incomingmessage

请求是上述对象的实例。顺便说一句,如果你真的想用“暴力”来查看那个对象里面的东西,你就不应该解析它,因为它根本不是JSON字符串,而是做类似的事情:

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

希望它有所帮助。

答案 1 :(得分:8)

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,这让人感到困惑。

例如,

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

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)

某些库假定存在Express'“req.param”方法,并且在非Express项目中使用时会失败。

答案 2 :(得分:6)

我同意Delio,Request对象属于IncomingMessage对象,由http.ClientRequest创建。
