chunk 是一个字符串，则第二个参数指定如何将这个字符串 编码成字节流，缺省情况下，编码为'utf8'。 注意:这是一个原始格式 http 报文体，和高层协议中的多段消息体编码格式({'Transfer-Encoding':'chunked'})无关。 第一次调用 response.write()时，此方法会将已经缓冲的消息头和第一块消息体发送给客户。 当第二次调用 response.write()的时候，node ClientRequest 对象 如果你就想要发送一个信息体，记得要在头信息里包含 Content-Length 项。如果你想要将 BODY 通过流的方式 传输发送，或许需要设置 Transfer-Encoding: chunked. 译注:大多数的站点相应用户请求时发送的 HTTP Headers 中包含 Content-Length 头.此头信息定义在 HTTP1.0协 议 RFC 1945 群：53090214 共同学习 NodeJS，欢迎加入。 38 那么浏览器就会白屏.这样导致比较糟糕的用户体验. 解决方法在 HTTP1.1协议.RFC2616中14.41章节中定义的 Transfer-Encoding:chunked 的头信息.chunked 编码定义在3.6.1中.根据此定义浏览器不需要等到内容字节全部下 载完成,只要接收到一个 chunked 块就可解析页面.并且可以下载 html

当接收到信息正文中的一部分时候会触发此事件。 Example: A chunk of the body is given as the single argument. The transfer-encoding has been decoded. The body chunk is a string. The body encoding is set with request.setBodyEncoding() is suggested to use the ['Transfer-Encoding', 'chunked'] header line when creating the request. 发送正文中的一块。用户可以通过多次调用这个方法将请求正文以流的方式发 送到服务器。此种情况建议在建立请求时使用['Transfer-Encoding', 'chunked']请求头。 The chunk
