In a Go web application, you receive JSON data from an external API. How would you validate and handle this data?
- Create a struct with optional fields and only parse the JSON data into the fields that match the expected structure.
- Implement custom validation functions for each field in the JSON data structure.
- Use Go's json.Unmarshal function to parse the JSON data into a struct and then validate each field individually using conditional statements.
- Utilize third-party validation libraries specifically designed for Go web applications.
When receiving JSON data in a Go web application, it's crucial to validate and handle it properly to ensure the application's robustness. The recommended approach is to use json.Unmarshal to parse the JSON data into a struct, which allows for easy access to individual fields. Then, you can validate each field using conditional statements, ensuring that the data meets the required criteria. This approach provides flexibility and control over the validation process within the application.
