Json is undefined in cURL

Question

I need to automate the issues insertion in Jira, so I need to use a REST API, I run the curl from the command line, here is my command

C:\WINDOWS\system32>curl.exe -D- -u fred:fred -X POST --data { "fields": {"project": { "key"="ZZZ-180" }, "summary": "REST TESTING" , "description": "Creation of a testing issue" , "issuretype" { "name": "Bug"}}} -H "Content-Type: application/json" http://ABCD.com:XXXX/rest/api/2/issue/

and here is what I receive:

curl: (6) Could not resolve host: fields
curl: (3) [globbing] unmatched brace at pos 10
curl: (3) [globbing] unmatched brace at pos 2
curl: (6) Could not resolve host: key=
curl: (6) Could not resolve host: ZZZ-180
curl: (3) [globbing] unmatched close brace/bracket at pos 1
curl: (6) Could not resolve host: summary
curl: (6) Could not resolve host: REST TESTING
curl: (6) Could not resolve host: ,
curl: (6) Could not resolve host: description
curl: (6) Could not resolve host: Creating of a testing issue
curl: (6) Could not resolve host: ,
curl: (6) Could not resolve host: issuretype
curl: (3) [globbing] unmatched brace at pos 2
curl: (6) Could not resolve host: name
curl: (3) [globbing] unmatched close brace/bracket at pos 4

Can anyone help me let the cURL define the JSON code written in data?

You have to quote the parameter, otherwise curl will use { as data and interpret the other parts as parameters (unknown)... — Stefano Sanfilippo

@Blundell. My case was the spaces on the string. So unusual to my understanding. Thank you. — m3nda

You would have to quote the string, but simplest way is putting JSON data in a file and asking cURL to read from it:

C:\WINDOWS\system32>curl.exe -D- -u fred:fred -X POST --data @data_to_send.json -H "Content-Type: application/json" http://ABCD.com:XXXX/rest/api/2/issue/

Note the @ before file name.

I tried it but still JSON code is totally undefined.. How to identify JSON in curl,,, I never used JSON before so Sorry for my lack of knowledge abt how to install JSON to be used in cURL

Stefano Sanfilippo Over a year ago

You do not have to install JSON, JSON is a file format ;) cURL will simply transfer the content of data_to_send.json: put the JSON string in it and navigate to the folder or give full path (like --data C:\path\to\data_to_send.json).

Thanks so much,,, The problem now is in the authorization to the REST API! thanks anyways

I was trying to write this command in perl script to be passed to the command prompt... I used backtracks `` but it was always giving an error for the @ notation before the JSON file path... any suggestions?

Your --data should look something like:

"{ \"fields\": {\"project\": { \"key\"=\"ZZZ-180\" }, \"summary\": \"REST TESTING\" , \"description\": \"Creation of a testing issue\" , \"issuretype\" { \"name\": \"Bug\"}}}"
