consider reading schema from a external file about njsonschema

[RicoSuter]

Try

var schema = JsonSchema4.FromJson(File.ReadAllText(...));

I thought it will just read the plain json text instead of schema . I will check and get back to you then .
Thanks for your quick help.

Hi Rico Suter,
Somehow this feature is not working for me with the version 1.22.5836.1197. I have created two sample json files stored in C:\Test folder as below.
C:\Test\Person.json
{
"type": "object",
"properties": {
"name": { "type": "string" },
"addresses": {
"type": "array",
"items": { "$ref": "address.json" }
}
}
}
C:\Test\address.json
{
"type": "object",
"properties": {
"street": {"type": "string"},
"city": {"type": "string"}
}
}
then I have created one sample tests as below.
var schema = JsonSchema4.FromJson(File.ReadAllText(@"c:\test\person.json"));
var data = JToken.Parse(File.ReadAllText(@"c:\test\data.json"));
var errors = schema.Validate(data);
First line throws exception
An unhandled exception of type 'System.NotSupportedException' occurred in NJsonSchema.dll
Additional information: Could not resolve the path 'address.json' because JSON file references are not supported.
Am I doing something wrong?. Please look into it.

[RicoSuter]

I think file references are not supported yet. I have to check the code tomorrow if there's an easy way to do this...

[khairnarnitin]

Okay, thanks for quick reply. It will be great help since it is part of Draft 4 Schema specs & we cant have large schema files.

[RicoSuter]

Ok, its fixed now in 1.23, please try again

[khairnarnitin]

Thanks. I will try with the latest 1.24 version. Does it supports web references?

[RicoSuter]

No, not yet. But i can add this too...

[RicoSuter]

Do you mean an absolute web references which starts either with "http" or "https"?

[khairnarnitin]

Okay thanks for quick reply :).
Yes exactly.

[khairnarnitin]

Tried with same sample using 1.24 but it is throwing exception
Could not resolve the path 'address.json' because no root path is available.

[RicoSuter]

You need to load it using the new method JsonSchema4.FromFile()

[RicoSuter]

... otherwise the file path is not known by the parser (as stated by the exception).

[khairnarnitin]

Yes... sorry my bad.. tried with FromFile(), it is working.
Cheers!!!

[RicoSuter]

v1.25 now supports now supports URL references...

[khairnarnitin]

Thanks it is working.

[khairnarnitin]

[RicoSuter]
