I have this:
JSON.parse('{"130.00000001":{"p_cod":"130.00000001","value":"130.00000001 HDD Upgrade to 2x 250GB HDD 2.5\" SATA2 7200rpm"}}');
JSONLint says it's perfectly valid json. But on execution I have a JSON.parse
error.
But, if I change my code to:
JSON.parse('{"130.00000001":{"p_cod":"130.00000001","value":"130.00000001 HDD Upgrade to 2x 250GB HDD 2.5\\" SATA2 7200rpm"}}');
(note the double backslash)
It works, but now JSONLint says invalid json
.
Can someone help to understand this behavior?
Strings in JSON are specified using double quotes, i.e., " . If the strings are enclosed using single quotes, then the JSON is an invalid JSON .
You can escape String in Java by putting a backslash in double quotes e.g.” can be escaped as\” if it occurs inside String itself. This is ok for a small JSON String but manually replacing each double quotes with escape character for even a medium size JSON is time taking, boring, and error-prone.
It's a difference between the wire format, and what you have to write in your code to get the wire format. When you declare this in code you need the double-\ in your literal so the string gets a single backslash (otherwise it will interpret \" as an escape sequence for just declaring a " and put that in your string). If you print out the value of the literal you will see a single backslash.
