JSON Schema Validator Wrapper Library

• JSON Schema validator wrapper library
• This library used to validate the json samples against the json schema. For this purpose, we have C++ json schema validator library. To use this library, C applications required a wrapper library with C linkage to use actual C++ validator library.

How to use it

• Link libjson_schema_validator_wrapper in the application.
• Include json_schema_validator_wrapper.h header in the application.

Public APIs

• int json_validator_init(const char *json_schema_path);
• int json_validator_validate_request(const char *json_string);
• int json_validator_terminate();

Example usage

 int ret;
 ret = json_validator_init("/tmp/json_schema.json");
 ...
 ret = json_validator_validate_request(buffer); /* buffer contains json message. */
 ...
 json_validator_terminate();
