How to make a POST request with parameters using Fast Networking Library in Kotlin Android

How to make a POST request with parameters using Fast Networking Library in Kotlin Android.

Here's a step-by-step tutorial on how to make a POST request with parameters using the Fast Networking Library in Kotlin for Android.

Step 1: Add the Fast Networking Library dependency​

To use the Fast Networking Library in your Android project, you need to add the dependency to your app-level build.gradle file. Open your build.gradle file and add the following line in the dependencies section:

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

Step 2: Add Internet permission to the manifest​

To make network requests, you need to add the Internet permission to your app's manifest file. Open your AndroidManifest.xml file and add the following line inside the <manifest> tag:

<uses-permission android:name="android.permission.INTERNET" />

Step 3: Create a new Kotlin file​

Create a new Kotlin file in your project and give it a suitable name, such as NetworkUtils.kt. This file will contain the code for making the POST request.

Step 4: Import the necessary classes​

In the newly created Kotlin file, import the required classes from the Fast Networking Library:

import com.androidnetworking.AndroidNetworking
import com.androidnetworking.common.Priority
import com.androidnetworking.interfaces.JSONObjectRequestListener

Step 5: Make the POST request​

Inside the NetworkUtils file, create a function to make the POST request. Here's an example of how you can do it:

fun makePostRequest(url: String, params: Map<String, String>, listener: JSONObjectRequestListener) {
    AndroidNetworking.post(url)
        .addBodyParameter(params)
        .setPriority(Priority.MEDIUM)
        .build()
        .getAsJSONObject(listener)
}

In this example, the function makePostRequest takes three parameters: the URL to which the request is made, the parameters to be sent as part of the POST request, and a listener to handle the response.

Step 6: Call the POST request function​

To make the POST request, call the makePostRequest function with the appropriate URL, parameters, and listener. Here's an example:

val url = "https://example.com/api"
val params = mapOf("key1" to "value1", "key2" to "value2")

makePostRequest(url, params, object : JSONObjectRequestListener {
    override fun onResponse(response: JSONObject?) {
        // Handle the response here
    }

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

In this example, we define the URL and parameters to be sent with the POST request. Then, we call the makePostRequest function and provide an anonymous implementation of the JSONObjectRequestListener interface to handle the response.

That's it! You have successfully made a POST request with parameters using the Fast Networking Library in Kotlin for Android. You can now handle the response and error inside the appropriate callback methods of the listener.
