How to add headers to a network request using Fast Networking Library in Kotlin Android

How to add headers to a network request using Fast Networking Library in Kotlin Android.

Here's a step-by-step tutorial on how to add headers to a network request using the Fast Networking Library in Kotlin Android:

Step 1: Add the Fast Networking Library dependency to your project​

To use the Fast Networking Library in your Android project, you need to add the library dependency to your project's build.gradle file. Open your project's build.gradle file and add the following line to the dependencies block:

implementation 'com.amitshekhar.android:android-networking:1.0.2'

Step 2: Make a network request​

To make a network request using the Fast Networking Library, you need to create an instance of the AndroidNetworking class. You can do this in your activity or fragment where you want to make the request. For example, in your MainActivity, add the following line to create an instance of AndroidNetworking:

val androidNetworking = AndroidNetworking.initialize(applicationContext)

Step 3: Add headers to the request​

To add headers to your network request, you can use the addHeaders() method provided by the AndroidNetworking library. This method takes a HashMap of key-value pairs, where the key is the header name and the value is the header value. For example, to add an Authorization header with a token value, you can use the following code:

val headers = HashMap<String, String>()
headers["Authorization"] = "Bearer your_token_here"

androidNetworking.get("https://api.example.com/data")
    .addHeaders(headers)
    .build()
    .getAsJSONObject(object : JSONObjectRequestListener {
        override fun onResponse(response: JSONObject?) {
            // Handle response
        }

        override fun onError(anError: ANError?) {
            // Handle error
        }
    })

In the above code, we create a HashMap called headers and add a key-value pair for the Authorization header. Then, we call the addHeaders() method on the AndroidNetworking instance and pass in the headers HashMap. Finally, we make a GET request to the specified URL and handle the response or error using the getAsJSONObject() method.

Step 4: Send the request​

After adding the headers to the request, you need to send the request using the appropriate method provided by the AndroidNetworking library. In the example above, we used the getAsJSONObject() method to send a GET request and expect a JSON response. However, you can also use other methods like getAsJSONArray() or getAsFile() depending on your needs.

That's it! You have successfully added headers to a network request using the Fast Networking Library in Kotlin Android. You can now build and run your project to test the network request with headers.
