Bash JSON string into variable - json

Question

my idea is to put json string into variable JSON, i have a command whom takes a console login to user in AWS IAM, the comand is : aws iam create-login-profile --cli-input-json file://create-login-profile.json
in create-login-profile.json is the json following content :
{
"UserName": "roberto.viquezzz",
"Password": "aaaaaaaaaaa",
"PasswordResetRequired": true}
i try to write bash script whom contains json var "JSON" like following code:
JSON="{\"UserName\": \"roberto.viquezzz\",\"Password\": \"aaaaaaaaaaa\",\"PasswordResetRequired\" : true}"
aws iam create-login-profile --cli-input-json $JSON
and if i type in console ./file.sh the file execute create a console user.
if it try to execute this code i get an error : Unknown options: "aaaaaaaaaaa","PasswordResetRequired", :, true}, "roberto.viquezzz","Password":
but if i execute this code from command line like :
aws iam create-login-profile --cli-input-json "{\"UserName\": \"roberto.viquezzz\",\"Password\": \"aaaaaaaaaaa\",\"PasswordResetRequired\": true}"
all is be ok , maybe whom know whats wrong ? please suggest!

Answer 1

Put quotes around $JSON:
aws iam create-login-profile --cli-input-json "$JSON"
The quotes that are there during the assignment get consumed by the shell. You can verify this by issuing echo $JSON.
By adding the quotes you will make sure that the entire string is passed to the command "aws" as a single argument.
