Curl call from Terminal and Shellscript is diffrent? - shell

I am calling the same curl command once from terminal and once from Shellscript - but the outcome is different:
#!/usr/bin/env bash
url="dev.test.ch"
http="http://"
test="192.168.178.107"
curl -H "'Host: $url'" "$http$test"
echo "'Host: $url'" "$http$test"
and
curl -H 'Host: dev.test.ch' http://192.168.178.107
Once I get the NGINX Startpage (from Shellscript) and once the right response (HTML Page from my App)
Any ideas?

Stupid me -
curl -H 'Host: '$newline "$http$test"
the braces were the problem.

You can use curl with -v option to see what exactly HTTP request was sent to server. Problem that in your script you curl adds 'Host header.
With this line curl -H "'Host: $url'" "$http$test" it sends
> GET http://192.168.178.107/ HTTP/1.1
> Host: 192.168.178.107
> User-Agent: curl/7.49.1
> Accept: */*
> 'Host: dev.test.ch'
If you remove single qoutes curl -v -H "Host: $url" "$http$test" it will send proper request:
> GET http://192.168.178.107/ HTTP/1.1
> Host: dev.test.ch
> User-Agent: curl/7.49.1
> Accept: */*

If anyone could help please
Should have mentioned I'm on windows. Apparently you have to escape those double quotes in the json
This works for me now:
curl -X POST -H Accept:application/json -H Content-Type:application/json -u neo4j:password -v http://localhost:7474/db/neo4j/tx/commit -d "{\"statements\":[{\"statement\":\"MATCH (n) RETURN n\"}]}"

parse error: Invalid numeric literal at line 1, column 7

I am trying to call an API using Curl. The request was timing out after 60 secs due to TCP Timeout. I added "-H "Connection: keep-alive" -H "Keep-Alive: timeout=90, max=100" to the existing code.
curl -s -X POST -u $regressionTestAuthToken -H Content-Type: application/json -H Accept: application/json -H "Connection: keep-alive" -H "Keep-Alive: timeout=90, max=100" $URL -d#"${WORKSPACE}"/tmp.json > "${WORKSPACE}"/out.json
After adding the Connection Keep-Alive, I am getting a parse error
parse error: Invalid numeric literal at line 1, column 7
Can someone help me to triage this issue?

Variable in command substitution is expanded into multiple arguments

I have tried to create a method in a bash script which should be able to perform a curl operation with a variable number of headers, however I seem to get stuck in that the curl command consider the header arguments to be multiple arguments as they contain spaces.
When I run the following line in bash I get a 201 response:
response=$($executable -X POST localhost:9200/index-template/globalmetadata --write-out '%{http_code}' --silent --output /dev/null --verbose --data "#${full_path}" -H "Content-Type: application/json" )
If I run the following:
#!/bin/bash
submit_request () {
full_path=/home/mat/globalmetadata.json
header_option=""
header_options=""
for header in "${#:1}"; do # looping over the elements of the $# array ($1, $2...)
header_option=$(printf " -H %s" "$header")
header_options=$(printf '%s%s' "$header_options" "$header_option")
done
echo Headers: $header_options
executable=curl
#response=$($executable -X POST localhost:9200/index-template/globalmetadata --write-out '%{http_code}' --silent --output /dev/null --verbose --data "#${full_path}" -H "Content-Type: application/json" )
response=$($executable -X POST localhost:9200/index-template/globalmetadata --write-out '%{http_code}' --silent --output /dev/null --verbose --data "#${full_path}" $header_option )
echo $response
}
submit_request "\"Content-Type: application/json\""
I get this output:
Headers: -H "Content-Type: application/json"

What I have noticed is that even though the headers are -H "Content-Type: application/json, curl says Could not resolve host: application. I suspect that it splits the arguments into two due to space between Content-Type: and application/json.
I tried to mix and match quotes and double quotes in all kinds of combination but nothing really worked.
#GordonDavisson is right, you'll have to put your header_options in an array. Just be aware that using the array "${header_options[#]}" when it is empty will result in an empty argument in your curl command, but You can get rid of this problem by storing the whole command in an other array.
submit_request () {
local -a header_options
for arg; do header_options+=(-H "$arg"); done
local -a curl_command=( \
curl \
-X POST \
localhost:9200/index-template/globalmetadata \
--write-out '%{http_code}' \
--silent \
--output /dev/null \
--verbose \
--data '#/home/mat/globalmetadata.json' \
"${header_options[#]}" \
)
local response=$( "${curl_command[#]}" )
printf '%s\n' "$response"
}

How to access Gravitee AM api

How to curl the basic gravitee am api? i tried the simple one also cant?
curl -X POST http://localhost:8093/admin/token -H 'authorization: Basic base64(admin:adminadmin)'
curl -X POST http://localhost:8093/admin/token -H 'Authorization: Basic YWRtaW46YWRtaW5hZG1pbg=='
It stated 404 Not found. Result are below:
* Trying 127.0.0.1...
* TCP_NODELAY set
* Connected to localhost (127.0.0.1) port 8093 (#0)
> POST /admin/token HTTP/1.1
> Host: localhost:8093
> User-Agent: curl/7.58.0

< Cache-Control: must-revalidate,no-cache,no-store
< Content-Type: text/html;charset=iso-8859-1
< Content-Length: 0

* Connection #0 to host localhost left intact
First you have to request an access token:
curl -X POST http://localhost:8093/management/auth/token -u admin:adminadmin
You should receive this payload:
{"access_token":"eyJraWQiOiJkZWZ......TyJ37E","expires_at":"Mon Nov 29 15:06:12 CET 2021","token_type":"bearer"}
Then you can use this access_token to request the access management API.
curl -X GET http://localhost:8093/management/organizations/DEFAULT/environments/DEFAULT/domains/ -H'Authorization: Bearer eyJraWQiOiJkZWZ......TyJ37E'

Can't insert variable with two headers in curl

I have following sh script
#!/usr/bin/env bash
headers='-H "custom1: ololo1" -H "custom2: ololo2"'
value_for_header="value"
curl -X "PUT" -H "Content-Type: application/json" -H "custom_ololo: $value_for_header" $headers http://localhost:8000/ -d '{"a": true}' -vv
Log when execute it:

* Hostname was NOT found in DNS cache
* Could not resolve host: ololo1"
* Closing connection 0
curl: (6) Could not resolve host: ololo1"

As we can see -H "custom_ololo: $value_for_header" works well > custom_ololo: value
But string $headers is not inserted correctly. I've tried put "$headers" and ${headers} but no result
So, my question is: How is correctly insert strings with several headers into sh script with curl.
You need to use an array, at which point you can put all the headers in the array and simplify your call.
#!/usr/bin/env bash
value_for_header="value"
headers=(
-H "custom1: ololo1"
-H "custom2: ololo2"
-H "Content-Type: application/json"
-H "custom_ololo: $value_for_header"
)
curl -X "PUT" "${headers[#]}" http://localhost:8000/ -d '{"a": true}' -vv
You need to put $headers into ""
curl -X "PUT" -H "Content-Type: application/json" -H "custom_ololo: $value_for_header" "$headers" http://localhost:8000/ -d '{"a": true}' -vv
