curl命令将zip压缩的POST正文发送到apache服务器 [英] curl command a gzipped POST body to an apache server

问题描述

在我的apache 2.2服务器上正确激活了mod_deflate的情况下，我正在尝试通过curl命令行发送一个压缩的正文.

With mod_deflate properly activated on my apache 2.2 server, I am trying to send a gzipped body via curl command line.

我见过的所有教程都说要添加-H'Content-Encoding:gzip'和gzip我的主体文件，但这失败了:

All tutorials I have seen say to add -H'Content-Encoding: gzip' and gzip my body file, however this fails:

echo '{ "mydummy" : "json" }' > body
gzip body
curl -v -i http://localhost/mymodule -H'Content-Encoding: gzip' --data-binary @body.gz 

我的apache模块收到0个字节

My apache module receives 0 bytes

在我的Apache error.log中，如果LogLevel设置为debug，我得到:
[Thu Jun 01 14:29:03 2017] [debug] mod_deflate.c(900): [client 127.0.0.1] Failed to inflate input: cannot handle deflate flags

And in my apache error.log if LogLevel is set to debug I get:
[Thu Jun 01 14:29:03 2017] [debug] mod_deflate.c(900): [client 127.0.0.1] Failed to inflate input: cannot handle deflate flags

推荐答案

问题是mod_deflate不喜欢此处显示的gzip标头:

The thing is that mod_deflate does not like the gzip header shown here:

hexdump -C body.gz
00000000  1f 8b 08 08 20 08 30 59  00 03 62 6f 64 79 00 ab  |.... .0Y..body..|
00000010  56 50 ca ad 4c 29 cd cd  ad 54 52 b0 52 50 ca 2a  |VP..L)...TR.RP.*|
00000020  ce cf 53 52 a8 e5 02 00  a6 6a 24 99 17 00 00 00  |..SR.....j$.....|
00000030

解决方案是简单地将其赋予gzip，而无需执行中间文件步骤，如果采用流处理，它将不会打印标题，并且apache会像正文一样！

The solution is simply to give it to gzip without the intermediate file step, if taking a stream, it will not print the headers and apache will like the body!

echo '{ "mydummy" : "json" }' | gzip > body.gz
curl -v -i http://localhost/mymodule -H'Content-Encoding: gzip' --data-binary @body.gz

这有效，apache模块接收解压缩的字节.

This works, the apache module receives the decompressed bytes.

您可以在此处看到标头的区别，您不再在gzip文件中看到文件名(正文):

You can see the header difference here, you no longer see the file name (body) in the gzip file:

hexdump -C body.gz
00000000  1f 8b 08 00 08 0a 30 59  00 03 ab 56 50 ca ad 4c  |......0Y...VP..L|
00000010  29 cd cd ad 54 52 b0 52  50 ca 2a ce cf 53 52 a8  |)...TR.RP.*..SR.|
00000020  e5 02 00 a6 6a 24 99 17  00 00 00                 |....j$.....|
0000002b
