分块传输编码浏览器体验 [英] Chunked transfer encoding browser experience

问题描述

为什么输出这个简单的Perl脚本>>

  printContent-type：text / plain\\\
 ; 
 printTransfer-Encoding：chunked\\\
\\\
; 
 print11\\\
\\\
; 
 print0123456789ABCDEF\\\
; 
 print11\\\
\\\
; 
 print0123456789ABCDEF\\\
; 
 print0\\\
\\\
; 
  

...适用于Chrome浏览器，不适用于IE10 ..

$ b你已经实现了分块传输编码错误：每个块由以十六进制符号表示的块大小（以字节为单位），后跟一个CRLF序列，后跟块数据：

  chunk = chunk-size [chunk-extension] CRLF 
 chunk-data CRLF 
 chunk-size = 1 * 
 last-chunk = 1 *（0）[chunk-extension] CRLF 
 chunk-data = chunk-size（OCTET）
  

所以你的代码应该是这样的：

  printContent-type：text / plain\r\\\
; 
 printTransfer-Encoding：chunked\r\\\
; 
打印\r\\\
; 
＃first chunk 
 print10\r\\\
; 
 print0123456789ABCDEF\r\\\
; 
＃second chunk 
 print10\r\\\
; 
 print0123456789ABCDEF\r\\\
; 
＃last chunk 
 print0\r\\\
; 
打印\r\\\
; 
  

Why the output of this simple Perl script >>

print "Content-type: text/plain\n";
print "Transfer-Encoding: chunked\n\n";
print "11\n\n";
print "0123456789ABCDEF\n";
print "11\n\n";
print "0123456789ABCDEF\n";
print "0\n\n";

...works for Chrome browser and does not for IE10..?

解决方案

You’ve implemented the chunked transfer coding wrong: Each chunk consists of the chunk size in bytes in hexadecimal notation, followed by a CRLF sequence, followed by the chunk data:

   chunk          = chunk-size [ chunk-extension ] CRLF
                    chunk-data CRLF
   chunk-size     = 1*HEX
   last-chunk     = 1*("0") [ chunk-extension ] CRLF
   chunk-data     = chunk-size(OCTET)

So your code should look like this:

print "Content-type: text/plain\r\n";
print "Transfer-Encoding: chunked\r\n";
print "\r\n";
# first chunk
print "10\r\n";
print "0123456789ABCDEF\r\n";
# second chunk
print "10\r\n";
print "0123456789ABCDEF\r\n";
# last chunk
print "0\r\n";
print "\r\n";
