In the mobile app development lifecycle, communicating with the server(via API) to get or store data is one of the basic needs.
Retrofit is a type-safe REST client for Android, Java and Kotlin developed by Square. The library provides a powerful framework for authenticating and interacting with APIs and sending network requests. I am writing this blog is written to express a special case while using Retrofit.
Let’s understand the use case with an example.
Suppose we need to override our API requests to add a key in every API of our project then we need to edit all our API requests or we can edit our client to add a key in all requests. We can do it by overriding our requests.
Below is the code example:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 |
Request request = chain.request(); Request.Builder builder = request.newBuilder(); if (request.method().equals("GET") || request.method().equals("PUT")) { HttpUrl originalHttpUrl = request.url(); HttpUrl url = originalHttpUrl.newBuilder() .addQueryParameter("lending_id", "disable") // Request customization: add request headers .build(); builder.url(url); } else { if ("POST".equals(request.method())) { if (request.body() instanceof FormBody) { FormBody.Builder bodyBuilder = new FormBody.Builder(); FormBody formBody = (FormBody) request.body(); // Copy the original parameters first for (int i = 0; i < formBody.size(); i++) { bodyBuilder.addEncoded(formBody.encodedName(i), formBody.encodedValue(i)); } // Add common parameters formBody = bodyBuilder .addEncoded("lending_id", "disable") .build(); builder.post(formBody).build(); } } } builder.addHeader("Content-Type", "text/html") .addHeader("authKey", ApplicationSingleton.getInstance().getAuthKey()); |
In conclusion, in this way we can override our requests with Retrofit.
