curl: (6) Couldn't resolve host 'fields'

[JVHE]

This question is in reference to Atlassian Developer Documentation: JIRA REST API Example - Edit issues

I'm experimenting with the REST Api described on this page :

https://developer.atlassian.com/jiradev/jira-apis/jira-rest-apis/jira-rest-api-tutorials/jira-rest-api-example-edit-issues

When I try the first example (Example of assigning an issue to user "harry"), I'm getting following errors :

curl: (6) Couldn't resolve host 'fields'
curl: (3) <url> malformed
curl: (6) Couldn't resolve host 'assignee:name'
curl: (3) [globbing] unmatched close brace/bracket in column 1
curl: (3) [globbing] unmatched close brace/bracket in column 1
HTTP/1.1 400 Bad Request

This is the command I'm sending : 

curl -D- -u %myuser:mypassword% -X PUT --data @data.txt -H "Content-Type: application/json" https://%mycloudurl%/rest/api/2/issue/%myissue%

data.txt : 

{
"fields": {
"assignee":{"name":"harry"}
}
}

Does anyone know what I'm doing wrong ?

I solved the problem by putting the data directly in the command and by using single quotes. 

Like this :

curl -D- -u %myuser:mypassword% -X PUT --data '{"fields": {"assignee":{"name":"harry"}}}' -H "Content-Type: application/json" https://%mycloudurl%/rest/api/2/issue/%myissue%

First problem is curl is not liking your input. Try to redo your input to something more similar to this example,

Good luck.
