JSON.Net: Schema validates where it shouldn't when using anyOf -


i'm trying detect if user specified boolean string instead of real boolean. i'm testing commentsmodule/enabled see if value false, once quotes , once without.

the online validator: http://json-schema-validator.herokuapp.com/ works correctly, , identifies failure "instance value (\"false\") not found in enum (possible values: [false])".

however, newtonsoft json (latest version) same schema , json defines valid json.

schema:

{     "$schema":"http://json-schema.org/draft-04/schema#",     "description": "pages json",     "type": "object",     "properties":         {         "name": {"type":"string"},         "description": {"type":"string"},         "channel": {"type":"string"},         "commentsmodule":{             "type": "object",             "anyof":[                  { "$ref": "#/definitions/commentsmoduledisabled" }                                                           ]         }     },     "definitions":{         "commentsmoduledisabled":{             "required": [ "enabled" ],             "properties": {                 "enabled": { "type": "boolean",  "enum": [ false ] }                     }           }         }                                 }

(using oneof gives same result)

json:

{ "_id": {     "$oid": "530dfec1e4b0ee95f0f3ce11" }, "pageid": 1234, "pagetype": "show", "name": "my name", "description": "this decription.” ", "channel": "tech", "commentsmodule": {     "captionfielddoesntexist": "comments",     "enabled": "false" },      "localinstance": "com", "productionyear": "2014", "navbarcaptionlink": "", "logoad": ""                 }

json.net code (taken official site):

        jsonschema schema = jsonschema.parse(schemajson);         jobject jsontoverify = jobject.parse(json);         ilist<string> messages;          bool valid = jsontoverify.isvalid(schema, out messages);

thank you!

edit: json.net doesn't support json schema v4, "definitions" references ignored.

for example, in case "caption" checked minimal length of 1, , has 0, json.net passes validation:

json

{ "_id": {     "$oid": "530dfec1e4b0ee95f0f3ce11" }, "pageid": 1234, "pagetype": "show", "name": "another name", "description": "description ", "channel": "tech", "commentsmodule": {     "caption": "",     "enabled": true },      "localinstance": "com", "productionyear": "2014", "navbarcaptionlink": "", "logoad": "" }

schema:

{     "$schema":"http://json-schema.org/draft-04/schema#", "description": "pages json", "type": "object", "properties":     {     "name": {"type":"string"},     "description": {"type":"string"},     "channel": {"type":"string"},     "commentsmodule":{         "type": "object",         "oneof":[              { "$ref": "#/definitions/commentsmoduledisabled" },              { "$ref": "#/definitions/commentsmoduleenabled" }            ]     } }, "definitions":{     "commentsmoduledisabled":{         "required": [ "enabled" ],         "properties": {             "enabled": { "type": "boolean",  "enum": [ false ] }                 }     },      "commentsmoduleenabled":{         "required": [ "enabled", "caption" ],         "properties": {             "enabled": { "type": "boolean",  "enum": [ true ] },             "caption": { "type": "string",  "minlength": 1 }                 }     } }   }

the error online tool in case talks mismatches both schemas , refers minimal length requirement:

 "message" : "instance failed match 1 schema (matched 0 out of 2)"  ...  "message" : "string \"\" short (length: 0, required minimum: 1)",

json.net doesn't support json schema v4, v3. that's why "anyof" , "definitions" not recognized , validation passes.

update:

json.net schema has full support draft 4.
