在groovy中从rabbitmq接收json

Question

I have problem with parsing json provided by RabbitMq. When I print Rabbit message i got:

{id=546456, userId=345345}

I need to parse this json with JsonSlurper but i got exception:

groovy.json.JsonException: Unable to parse JSON object



     The current character read is '{' with an int value of 123
    expecting '}' or ',' but got current char 'i' with an int value of 105
    line number 1
    index number 1

It seems that quotes chars are missing. How to parse it without errors? Thanks

edit

When i send this message:

{'id':663558460,"userId":345345}

I recive this message in same form eg:

{'id':663558460,"userId":345345}

But there is another exception:

The current character read is ''' with an int value of 39
expecting '}' or ',' but got current char ''' with an int value of 39
line number 1
index number 1

Answer 1

this is not valid JSON: {id=546456, userId=345345}

neither is this: {'id':663558460,"userId":345345}

the JSON spec requires double-quotes for keys and string values.

this is valid JSON: {"id":663558460,"userId":345345}

note the double quotes around both keys. You need to adjust your code to send your JSON documents properly formatted

Answer 2

Sometimes, jq (the JSON Query processor) can be helpful with quasi-JSON input. In the particular case you give, if the quasi-JSON text is put in a file named invalid.json:

$ jq -n -f <(sed 's/=/:/g' invalid.json)
{
  "id": 546456,
  "userId": 345345
}

The above only works because in your case, substituting ":" for "=" blindly is satisfactory.

Even if that is not the case, however, chances are that the combination of jq and some "text-wrangling" will do the job.
