response body format - access logs

fewzee

Hello everyone,

I'm using nginx as reverse proxy and logging the upstream response through lua by concatenating ngx.arg[1] until ngx.arg[2] is true. As the response size increases, the format of the response changes as well and I haven't yet been able to decode it.

Examples are shorter and longer responses collected from access log are as follows:

\"{\\x22data\\x22:\\x22testingwooooooooo\\x22}\"

\"!\\xD0\\x00\\x00 \\xC4\\x8C#\\x7F\\xC1T\\xC2`\\xB7\\x96d\\x92N\\xAA\\x91HwzV\\x96D\\xD6\\xB7\\xC2\\x0F\"

Has anyone else experienced this? What is the encoding?!

Thanks,

Pouria
