busybox wget Transfer-Encoding chunked

[Steve W.]

Hi,

I experience an issue with Busybox wget running on a Openwrt box, version "BusyBox v1.28.3". When sending a POST request wget uses Transfer-Encoding "chunked" and does not provide Content-Length

The issue is that my web application expects Content-Length and does not support chunked transfer

Here is an example:

wget --post-data="a=b" http://httpbin.org/post -O -

Gives:

"headers": {
    "Connection": "close",
    "Content-Type": "application/x-www-form-urlencoded",
    "Host": "httpbin.org",
    "Transfer-Encoding": "chunked",
    "User-Agent": "uclient-fetch"


The payload string "a=b" is of known length so there should be no problem to provide the content length. And I checked standard wget implementation (shipped with Ubuntu 16.04) - it does not use chunked transfer and correctly specifies the content length

 "headers": {
    "Accept": "*/*",
    "Accept-Encoding": "identity",
    "Connection": "close",
    "Content-Length": "3",
    "Content-Type": "application/x-www-form-urlencoded",
    "Host": "httpbin.org",
    "User-Agent": "Wget/1.17.1 (linux-gnueabihf)"


Is there a way to make busybox to supply content-length during POST request?

Thanks,
Steve
