爲了更好地理解內在的的NodeJS模塊之一,你應該先閱讀其文檔。然後,如果需要進一步理解,您將需要探索定義它的源代碼。 (大多數內在模塊本身都是用JavaScript編寫的)。
例如,ServerResponse對象(通常作爲「res」傳入HTTP請求處理程序)在http.js的第867行中定義,可以在nodejs源代碼https://github.com/joyent/node/blob/master/lib/http.js
通過探索源代碼,您將能夠看到對象支持的方法和屬性。
然後,要完全理解一個對象是如何工作的並且發現其方法和屬性的全部,則需要遵循其繼承樹。
ServerResponse從
OutgoingMessage(在相同的文件中定義的),其本身從
流(在stream.js定義)繼承繼承其進一步繼承
events.EventEmitter,當然是
對象
所以,方法和ServerResponse的特性的完整列表是:
ServerResponse
statusCode property
_implicitHeader() method
assignSocket() method
detachSocket() method
writeContinue() method
writeHead() method
writeHeader() method
_buffer() (from OutputMessage) method
_finish() (from OutputMessage) method
_flush() (from OutputMessage) method
_renderHeaders() (from OutputMessage) method
_send() (from OutputMessage) method
_storeHeader() (from OutputMessage) method
_writeRaw() (from OutputMessage) method
addTrailers() (from OutputMessage) method
destroy() (from OutputMessage) method
end (from OutputMessage) method
getHeader() (from OutputMessage) method
removeHeader() (from OutputMessage) method
setHeader() (from OutputMessage) method
write() (from OutputMessage) method
pipe() (from Stream) method
addListener() (from EventEmitter) method
emit() (from EventEmitter) method
listeners() (from EventEmitter) method
on() (from EventEmitter) method
once() (from EventEmitter) method
removeAllListeners() (from EventEmitter) method
removeListener() (from EventEmitter) method
setMaxListeners() (from EventEmitter) method
arguments (from Object) property
caller (from Object) property
length (from Object) property
name (from Object) property
prototype (from Object) property
super_ (from Object) property
__defineGetter__() (from Object) method
__defineSetter__() (from Object) method
__lookupGetter__() (from Object) method
__lookupSetter__() (from Object) method
constructor() (from Object) method
hasOwnProperty() (from Object) method
isPrototypeOf() (from Object) method
propertyIsEnumerable() (from Object) method
toLocaleString() (from Object) method
toString() (from Object) method
valueOf() (from Object) method
apply() (from Object) method
bind() (from Object) method
call() (from Object) method
通過跟隨對象的整個繼承樹,你建一個深入瞭解nodejs是如何工作的,並瞭解它是一個了不起的工具。
你可以找到很多在任何Node.js的手工網站列出的屬性,如http://nodemanual.org/latest/nodejs_dev_guide/creating_an_http_server.html
最簡單的方法來找出其中的JavaScript功能,性能,...一個對象是將對象序列化爲一個字符串並將該字符串輸出到控制檯。
基本上這是一個一行,如:
console.log(JSON.stringify(req));
這說明你的一切req
對象了。
謝謝,羅布。我可以同樣獲得請求支持和方法嗎? – vinod
如何獲取整個html頁面?是否有可能通過任何「res」屬性? – VVB
