perl - 分块传输编码浏览器体验

Question

为什么这个简单的 Perl 脚本的输出 >>

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";

...适用于 Chrome 浏览器，不适用于 IE10..？

Answer 1

您错误地实现了分块传输编码：每个块都包含以十六进制表示的块大小（以字节为单位），然后是 CRLF 序列，然后是块数据：

   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)

所以你的代码应该是这样的：

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";
