I am new to shell. I am using curl in my Jenkins job.
I am getting the expected output if I hardcode the payload in the curl request
curl -i -X POST $url --header "'Content-Type: application/json'" --data-raw {"deployed": true}
But when I try and store it as a variable, I see I am getting errors, even though the curl output I get as part of the Jenkins pipeline is exactly the same
payload='{"deployed": true}'
curl -i -X POST $url --header "'Content-Type: application/json'" --data-raw $payload
Need help in understanding how are the different

I am very new to bash scripting, please can someone point me in the right direction on how to accomplish my task?
I have a curl call which returns a string, which I want to convert to json.
My curl statement -
curl --insecure -X POST 'https://url/api/IPAM/GetIP' --header 'Content-Type: application/json' --header -d '{"key1": "value1"}'
This curl statement returns a string ,for example: 10.100.100.100
I want to fetch this string and return the output in json format:
{"IP":"10.100.100.100"}
I don't want to use jquery or python to do this because this entire script will be run by a wrapper that only understands bash.
You can use jq to process your IP string into a JSON string and package it into a JSON object of your choice.
ip="10.100.100.100"
jq --arg ip "$ip" -cn '{"IP":$ip}'
Result:
{"IP":"10.100.100.100"}
Now if working with the result of your example curl POST request:
rawip_string=$(curl --insecure -X POST 'https://url/api/IPAM/GetIP' --header 'Content-Type: application/json' --header -d '{"key1": "value1"}')
jq --arg ip "$rawip_string" -cn '{"IP":$ip}'
One way to not rely on external tools like jq, you can get the output ip attribute that to a variable and concatenate it.
$ return=$(echo 10.100.100.100)
$ echo "{\"IP\":\"${return}\"}"
{"IP":"10.100.100.100"}
Like this
printf '{"IP":"%s"}' "$(curl --insecure -X POST 'https://url/api/IPAM/GetIP' --header 'Content-Type: application/json' --header -d '{"key1": "value1"}')"
I 'd like to post directly a json object from a url(json) to another url
so the command goes as follows:
curl "<resource_link>.json" -o sample.json
curl -X POST "<my_link>" "Content-type: application/json" -d #sample.json
I 'd like to avoid this, so what is the solution? Is it something like that?
curl -X POST "<my_link>" "Content-type: application/json" -d "curl <resource_link>.json"
But it does not work? Also, this one post Stream cURL response to another cURL command posting the result
does not explain thouroughly and it is not working
Yes,
curl
manual explains the '#' but it does not explain about using another curl
Alternatievely, if I could save somewhere temporarily the 1st cURL response and use it in the other command(but not in a file)
You don't want -x POST in there so let's start with dropping that.
Send the results from the first transfer to stdout by not using -o, or telling -o to use stdout with -o-, and
Make sure your second transfer accepts the data to send on stdin, by using -d#-.
curl "<link>.json" | curl "<link2>" -H "Content-type: application/json" -d #-
With curl 7.82.0 and later
Starting with curl 7.82.0 you can do it even easier with the new --json option:
curl "<link>.json" | curl "<link2>" --json #-
I am trying to execute a curl command using an environment variable.
curl -u {user}: -X POST --header 'Content-Type: application/json' -d '{"my-var": " '"$ENV_VAR"' "}' https://url
However, this is not correctly fetching the output of $ENV_VAR, and instead passes in the string $ENV_VAR
The above implementation was taken from this question.
How do I correctly pass the value of the environment variable into the curl command?
I am able to execute the below cURL request (generated in PostMan) through a Git Bash in windows, and receive a response as expected.
curl -X GET \ https://test.amazon.com/production/john.stones \
-H 'authorization: Bearer dfgjdrjkdrt' \
-H 'cache-control: no-cache' \
-H 'content-type: application/json' \
-H 'postman-token: 53a3fs9a-5ce3-10fe-7f0a-33e9695ec514' \
-H 'referer: king'
I wish to run multiple cURL requests, around a thousand like the above, with the name being the value that changes in each request. I tried placing them into a batch file but each line is taken as a command, so a bit unsure as to how to structure them. Anyone know how I can run multiple cURL requests, either in sequence or parallel, in Windows 10?
I have addressed this by listing each cURL request in a batch file, replacing all single quotes with double and removed all '\' generated in Postman to divide headers. Only after this does windows run the requests successfully.
when i post a raw string as an input to JSON REST Service call it is executing ex:
curl -d "{\"input1\": \"as\", \"input2\": \"ad\"}" -i -X POST -H "Content-Type:application/json" http://localhost/rtygies/Service1.svc/rest/receivedata1
But when i am posting as an xml as input it is giveng error as below:
curl -d "{\"input1\": \"<xml></xml>\", \"input2\": \"<xml></xml>\"}" -i -X POST -H "Content-Type:application/json" http://localhost/rtygies/Service1.svc/rest/receivedata1
Error: < was unexpected at this time
I am using curl in windows.
can any one say how to post xml as a string input to Rest service in JSON format from curl
Actually, I don't know what is the case,
but I got an error said < is unexpected this time
when I tried the following command (on windows):
curl -u admin:password -XPOST -H 'Content-type: text/xml' -d '<namespace><prefix>newWorkspace</prefix><uri>http://geoserver.org</uri></namespace>' http://localhost:8080/geoserver/rest/namespaces
Then I changed the single quote into double quotes and it worked.
Redirection symbols can be escaped by "
Try using
curl -d "{\"input1\": \""<xml></xml>"\", \"input2\": \""<xml></xml>"\"}" -i -X POST -H "Content-Type:application/json" http://localhost/rtygies/Service1.svc/rest/receivedata1
I had no luck with double-quotes, however escaping < and > with ^ worked for me.
So your curl becomes..
curl -d "{\"input1\": \"^<xml^>^</xml^>\", \"input2\": \"^<xml^>^</xml^>\"}" -i -X POST -H "Content-Type:application/json" http://localhost/rtygies/Service1.svc/rest/receivedata1
