I have been hitting a curl command with queryparametr in the request and passing a json format in the query parameter , but I am getting error like (" some well formatted json in parameter query.unexpected character encountered parsing error while parsing value .
curl -g --request GET -H "Content-Type:application/json" -H "apitoken:abcd" "https://odat.abc.com/api/data?query=$(echo '$jsonInput')"
jsonInput is the json format file we are passing here.
See https://stackoverflow.com/a/32980082/1395722
curl -G --request GET -H "Content-Type:application/json" -H "apitoken:abcd" "https://odat.abc.com/api/data" --data-urlencode "query=$(echo $jsonInput)"

I have a command that is stored in a variable. I would like to execute that command and then store the response of that command in a variable. I'm having an issue with syntax errors for the responseVar=$("{commandVar}") line as it seems to trigger a "no such file or directory" error instead of actually running the command/storing the output in the response variable.
commandVar="curl --location -g --request POST 'https://172.217.25.35/rest-gateway/rest/api/v1/auth/token' --header 'Content-Type: application/json' --header 'Authorization: Basic U0FNcWE6NTYyMFNhbSE=' --data-raw '{"grant_type": "client_credentials"}'"
responseVar=$("{commandVar}")
echo "Response of command: ${responseVar}"
Does anyone know the correct syntax on how I would do this? I need to eventually parse the output of the command which is why I need to store the response in it's own variable.
You are trying to execute a program named {commandVar}, and this program does not exist in your PATH.
To start with, you better use an array to store your command, each array element holding one command argument:
commandVar=(curl --location -g --request POST 'https://172.217.25.35/rest-gateway/rest/api/v1/auth/token' --header 'Content-Type: application/json' --header 'Authorization: Basic U0FNcWE6NTYyMFNhbSE=' --data-raw '{"grant_type": "client_credentials"}')
With this, you can execute it by
"${commandVar[#]}"
respectively store its standardoutput into a variable like this:
responseVar=$( "${commandVar[#]}" )
I am running out of ideas to have this to work in my gitlab-ci.yml.
I have a variable called TARGET, and I want to successfully inject its value inside the json payload of my http POST request in form of curl bash command.
job:
stage: deploy
script:
- curl -k --request POST ${URL} --header "Authorization:Basic ${TOKEN}" --header 'Content-Type:application/json' --data "{"extra_vars":{"target":${TARGET}}}"
variables:
TARGET: host1
the pipeline output keeps complaining with error message:
{"detail":"JSON parse error - Expecting property name enclosed in double quotes: line 1 column 2 (char 1)\nPossible cause: trailing comma."}
I also tried escaping some special characters with \ as below, but not working either:
curl -k --request POST ${URL} --header "Authorization:Basic ${TOKEN}" --header 'Content-Type:application/json' --data "\{"extra_vars":\{"target":${TARGET}\}\}"
your helps are very appreciated.
There are two issues here. You are missing double quotes around the value for target inside the JSON since TARGET is a string value.
You are also wrapping your data argument with double quotes hence you should not use them inside the payload without either escaping them or switching to single quotes.
Keeping that in mind the payload may look something like this:
'{"extra_vars":{"target":"'${TARGET}'"}}'
Here's a quick tip on how to test the output using httpbin.org:
TARGET=host1 && curl -v https://httpbin.org/post -H "Content-Type: application/json" -d '{"extra_vars":{"target":"'${TARGET}'"}}'
Which will respond with the sent payload (which is ofcourse escaped as it is also wrapped inside JSON:
"data": "{\"extra_vars\":{\"target\":\"host1\"}}",
How we can add JSON parameters in a curl command to fetch data ?
PS: I have tried to fetch data from some source using curl command but it requires passing JSON parameters in it. So how I will accomplish it ?
I think mentioning content type as json and passing data will do the things right
curl -H "Content-Type: application/json" -d '{"key1":"value1","key2":"value2"}' http://domain.com/rest/path/here
Above will work for GET Method, for POST method
curl -H "Content-Type: application/json" -X POST -d '{"key1":"value1","key2":"value2"}' http://domain.com/rest/path/here
I need to get all repositories with a provided name from DockerHub. I already tried various ways to get to next page of results received for the following call:
curl -k -H "Accept: application/json" -X GET https://index.docker.io/v1/search?q=sonarqube
Options which haven't worked:
curl -k -H "Accept: application/json" -X GET https://index.docker.io/v1/search?q=sonarqube&n=25&page=2
curl -k -H "Accept: application/json" -X GET https://index.docker.io/v1/search?q=sonarqube&page_size=25&page=2
Am I missing anything, or is there an alternative to get these results?
I simply used this link to navigate to the second page:
https://index.docker.io/v1/search?q=sonarqube&page=2
I works for page attibute range from 1 to num_pages which is returned in the JSON response. If you provided a number higher than num_pages it returns the last page.
Curl command as requested:
curl -k -H "Accept: application/json" -X GET "https://index.docker.io/v1/search?q=sonarqube&page=2"
I am trying to post two parameters using curl, path and fileName:
curl --request POST 'http://localhost/Service' --data "path='/xyz/pqr/test/'&fileName='1.doc'"
I know something is wrong in this.
I have to use something like URLEncode. I tried many things still no luck.
Please give an example how can I post the url in data of curl request.
Perhaps you don't have to include the single quotes:
curl --request POST 'http://localhost/Service' --data "path=/xyz/pqr/test/&fileName=1.doc"
Update: Reading curl's manual, you could actually separate both fields with two --data:
curl --request POST 'http://localhost/Service' --data "path=/xyz/pqr/test/" --data "fileName=1.doc"
You could also try --data-binary:
curl --request POST 'http://localhost/Service' --data-binary "path=/xyz/pqr/test/" --data-binary "fileName=1.doc"
And --data-urlencode:
curl --request POST 'http://localhost/Service' --data-urlencode "path=/xyz/pqr/test/" --data-urlencode "fileName=1.doc"
I don't think it's necessary to use semi-quotes around the variables, try:
curl -XPOST 'http://localhost/Service' -d "path=%2fxyz%2fpqr%2ftest%2f&fileName=1.doc"
%2f is the escape code for a /.

Also, do you need to specify a port? ( just checking :) )
