Package jsonschema provides json-schema compilation and validation.
This implementation of JSON Schema, supports draft4 and draft6.
Passes all tests(including optional) in https://github.com/json-schema/JSON-Schema-Test-Suite
An example of using this package:
schema, err := jsonschema.Compile("schemas/purchaseOrder.json")
if err != nil {
return err
}
f, err := os.Open("purchaseOrder.json")
if err != nil {
return err
}
defer f.Close()
if err = schema.Validate(f); err != nil {
return err
}
The schema is compiled against the version specified in `$schema` property.
If `$schema` property is missing, it uses latest draft which currently is draft6.
You can force to use draft4 when `$schema` is missing, as follows:
compiler := jsonschema.NewCompiler()
compler.Draft = jsonschema.Draft4
you can also validate go value using schema.ValidateInterface(interface{}) method.
but the argument should not be user-defined struct.
This package supports loading json-schema from filePath and fileURL.
To load json-schema from HTTPURL, add following import:
import _ "github.com/santhosh-tekuri/jsonschema/httploader"
Loading from urls for other schemes (such as ftp), can be plugged in. see package jsonschema/httploader
for an example
To load json-schema from in-memory:
data := `{"type": "string"}`
url := "sch.json"
compiler := jsonschema.NewCompiler()
if err := compiler.AddResource(url, strings.NewReader(data)); err != nil {
return err
}
schema, err := compiler.Compile(url)
if err != nil {
return err
}
f, err := os.Open("doc.json")
if err != nil {
return err
}
defer f.Close()
if err = schema.Validate(f); err != nil {
return err
}
This package supports json string formats: date-time, hostname, email, ip-address, ipv4, ipv6, uri, uriref, regex,
format, json-pointer, uri-template (limited validation).
Developers can define their own formats using package jsonschema/formats.
The ValidationError returned by Validate method contains detailed context to understand why and where the error is.
