问题
This string is part a JSON object/file:
"Mask" : "{0}(CASE WHEN {1} = {2} THEN {3} ELSE 0 END) {4}"
Will JSON recognize that as part of standard JSON notation or do I need to escape those curly braces s somehow?
If so, how does one escape curly braces in JSON?
回答1:
No. Curly braces do not have to be escaped in JSON.
回答2:
No, curly braces do not have to be escaped in JSON strings.
JSON is defined in RFC 7159. The Section 7: Strings lists the string characters that must be escaped:
All Unicode characters may be placed within the quotation marks, except for the characters that must be escaped: quotation mark, reverse solidus, and the control characters (U+0000 through U+001F).
While all characters can be escaped, curly braces do not have to be.
