When it comes to Android development, specifically using Retrofit with Kotlin, there can be situations where you want to conditionally remove a specific header for particular requests. In this guide, we will explore a practical solution for removing a certain header only when necessary while still maintaining a clean and efficient codebase. The Problem You may have a Retrofit interceptor that sets headers for authentication purposes. However, what if there’s a request where you don't want to include a specific header, while keeping your interceptor setup intact? This is a common issue that developers may face while implementing secure API services. For instance, you might want to remove the HEADER_APP_TOKEN when making a request to retrieve a particular resource, but include it for others. Our Approach Step 1: Modify Your API Service To address this, we will implement a way to signify whether a request should include authentication headers through custom headers in the API service. We can add an extra header called isAuthorizable for that purpose. Here’s how you can modify your interface: [[See Video to Reveal this Text or Code Snippet]] Step 2: Adjust Your AuthInterceptor In the AuthInterceptor, we'll check for the presence of the isAuthorizable header and decide whether to apply the authentication headers or not. Here’s the modification you need to make to your AuthInterceptor: [[See Video to Reveal this Text or Code Snippet]] Key Points to Remember Custom Headers: By using a custom header isAuthorizable, you can control the addition of authentication headers dynamically based on the request type. Efficient Interceptor Use: This solution preserves the interceptor’s functionality, allowing you to maintain clean code with minimal adjustments. Maintain Readability: The designed approach keeps your API service and interceptors readable, which is essential for team collaboration. Conclusion By implementing this method, you can effectively manage specific headers in your Retrofit API requests. This allows your application to maintain flexibility in handling requests that require different authentication methods without duplicating code or complicating your interceptor logic. Embrace these best practices to ensure a more organized and efficient API management strategy in your Android projects. Now you should be well-equipped to handle situations where you need to conditionally remove headers in Retrofit! Happy coding!
