Linux curl post request and Error 417 but sudo success? -


my service deployed in docker,the exposed nginx port 18082;service port 38087,and tried both.

while use command

curl -i -x post -h 'content-type: text/json' -d @post.json \ http://127.0.0.1:18082/youtu/openliveapi/livedetectfour

return 417

http/1.1 417 expectation failed server: squid/2.7.stable9 date: tue, 15 aug 2017 11:57:04 gmt content-type: text/html content-length: 1436 x-squid-error: err_invalid_req 0 x-cache: miss sk-squiddev-118 x-cache-lookup: none sk-squiddev-118:8080 connection: close

but when add sudo in front,it return success. http/1.1 100 continue http/1.1 200 ok server: openresty/1.9.15.1

i search , knew while curl post on 1024 bytes,it first send

expect 100-continue.if server don't support request, return 417 error.

then how can sudo succsess,maybe related nginx mechanism,i'm not familiar that.thanks.

since using proxy in corporate setup , proxy might insert in user's bash profile. can 3 things

update ~/.bash_profile or ~/.bashrc

remove proxy profile , won't need proxy

unset variables

you can unset variables before call

unset http_proxy unset https_proxy curl -i -x post -h 'content-type: text/json' -d @post.json \ http://127.0.0.1:18082/youtu/openliveapi/livedetectfour

blank variables call

you can set variables 1 curl call

http_proxy= https_proxy= curl -i -x post -h 'content-type: text/json' -d @post.json \ http://127.0.0.1:18082/youtu/openliveapi/livedetectfour
