This repository does not house the latest specifications nor does it implement the latest versions of JSON Schema. This package seeks to maintain the stability (in behavior and size) of this original implementation for the sake of the numerous packages that rely on it.

How Do I Validate a JSON file With a Schema in VB.Net?

Asked 2021-Jun-14 at 13:10

I'm trying to validate some JSON files on VB.net. However, Whenever I run my code it gets stuck on

Dim Schema As JsonSchema = JsonSchema.Parse(SchemaString)

The Error Says

An unhandled exception of type 'Newtonsoft.Json.JsonException' occurred in Newtonsoft.Json.dll.

There is also a warning that says that JSON validation moved to its own package. So, I'm pretty sure I'm just importing the wrong packages, but I'm not sure.

I would be grateful if anyone could point me in the correct direction,

Thank you.

$schema is only valid at the root, and properties values MUST be schemas.

You have a "$schema" : "#" inside properties. This means that you're trying to say that your JSON object should have a property called schema that can validate against the schema #. But # isn't a valid schema object, so the parse fails.

You need to remove the $schema from your properties.

I'd also suggest using a later draft of the schema spec (if you have control over the schema). Draft 6 is the oldest version that's compatible with the latest, 2020-12.

But for this you'll likely need to use a different validation package. There are several available. Mine is JsonSchema.Net.

Json-schema required/non-required & allowed valeus for fields depend on the values of other fields

I have three fields, foo, bar, baz. bar depends on foo, baz depends on bar:

foo is bool
if foo is not provided bar & baz are forbidden

foo = false: bar & baz are forbidden
foo = true & bar = bar1: baz is a required object with required field baz1 and non-required field baz2 both string
foo = true & bar = bar2: baz is a required object with required field baz3 string

You should split up the required clauses so they check one keyword at a time.

"required": ["bar", "baz"] will be false if neither 'bar' nor 'baz' are present, which is what you want, but it will also be false if one property is present and the other is not, which is not (because you then wrap that check with a "not", making the "if" condition true).

Therefore, change that check to:

If my understanding is correct, you want to refer from dummy-1.json to subschemas defined in definitions-1.json. To do that, you have to specify the URI of definition-1.json and append the pointer of the subschema in it, like:

0# is a relative json pointer for the current members name or array index.

ajv-errors bases this lookup on the { field: value } data it is validating rather than somewhere in the schema.

So inside a property errorMessage you have access to an object 1 level up:

Ansible picked up support for jsonschema, and I have a variety of use cases for it, but most all of them require conditionals.

Generally, you're going to have a hard time whenever you choose to restrict unknown properties. I'll assume you have a good reason and including it is worth it.

There are a couple ways to do this. I'm presenting it this way because it produces the best messages when a JSON instance fails schema validation.

Validate JSON in Scala

Asked 2021-Jun-03 at 15:55

New to Scala and Java, coming from Python & JavaScript.

Not looking for solutions involving Spark.

I need suggestions with and without an external library ( like https://github.com/java-json-tools/json-schema-validator, please suggest if there is something better) to validate.

I aim to validate a JSON (available to me in a multiline file of json type) against a provided json-schema (draft-4 version) and print around what value(s) it did not comply.

Here is what I tried, not sure how to proceed further with validating JsonObject (as recieved at parsedJson variable) with the schema I have. For the method where I don't want to depend on an external library to validate, do I write multiple if...else conditions to check the validity of given JSON file? please suggest better approaches, I have no knowledge of Java and Scala.

java-json-tools/json-schema-validator seems not to have been updated for some time. I'd probably pick one of the libraries listed here. These two seem to be most actively maintained: everit-org/json-schema and networknt/json-schema-validator.

networknt/json-schema-validator works with Jackson, which is one of the most popular JSON libraries in the Java world, so it should suit your needs. Here's a simple example of how you could validate a JSON object and print errors (I omitted error handling for the sake of simplicity):

ANSWER

Answered 2021-Jun-01 at 10:03

You need to use the additionalProperties keyword.

The behavior of this keyword depends on the presence and annotation results of "properties" and "patternProperties" within the same schema object. Validation with "additionalProperties" applies only to the child values of instance names that do not appear in the annotation results of either "properties" or "patternProperties".

https://json-schema.org/draft/2020-12/json-schema-core.html#rfc.section.10.3.2.3

In laymans terms, if you don't define properties or patternProperties the schema value of additionalProperties is applied to all values in the object at that instance location.

Often additionalProperties is only given a true or false value, but rememeber, booleans are valid schema values.

If you have constraints on the keys for the object, you may wish to use patternPoperties followed by additionalProperties: false.

Formatting a single field to display a button based on a choice fields value using JSON

I have a field that defines the document being approved. Field Name is "WorkflowRequired", which is a choice field. I would like to display a button based on that choice. I can do this singularly but when I attempt to incorporate multiple if statements, the logic fails.

This is what I have. { "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",

In short, if you want to apply the if condition, you will need to place it after the properties. It is just like "elmType": "button", "txtContent":"=IF()"

It was news to me, but according to the spec it does seem that objects are valid enum values. That said, your usage is quite unusual. I've not seen it used before.

Elements in the array might be of any type, including null.
