Introduction to Fast Networking Library

Fast Networking Library is a powerful networking library for Android that simplifies the process of making HTTP requests and handling responses. It provides an intuitive and easy-to-use API for handling various networking tasks, including handling cookies.

Adding Fast Networking Library to the Project

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

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

Sync your project with Gradle files to ensure the library is successfully added to your project.

Making a GET Request with Cookies

To make a GET request with cookies using Fast Networking Library, you can use the AndroidNetworking class. Here's an example:

AndroidNetworking.get("https://example.com/api/data")
    .addHeaders("Cookie", "sessionid=1234567890")
    .build()
    .getAsJSONObject(object : JSONObjectRequestListener {
        override fun onResponse(response: JSONObject) {
            // Handle the response
        }

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

In the above example, we make a GET request to the URL "https://example.com/api/data" and add a cookie header with the name "sessionid" and value "1234567890" using the addHeaders method.

Making a POST Request with Cookies

To make a POST request with cookies using Fast Networking Library, you can use the AndroidNetworking class. Here's an example:

AndroidNetworking.post("https://example.com/api/data")
    .addHeaders("Cookie", "sessionid=1234567890")
    .addBodyParameter("param1", "value1")
    .addBodyParameter("param2", "value2")
    .build()
    .getAsJSONObject(object : JSONObjectRequestListener {
        override fun onResponse(response: JSONObject) {
            // Handle the response
        }

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

In the above example, we make a POST request to the URL "https://example.com/api/data" and add a cookie header with the name "sessionid" and value "1234567890" using the addHeaders method. We also add body parameters using the addBodyParameter method.

Retrieving Cookies from a Response

To retrieve cookies from a response using Fast Networking Library, you can use the ANResponse class. Here's an example:

AndroidNetworking.get("https://example.com/api/data")
    .build()
    .getAsJSONObject(object : JSONObjectRequestListener {
        override fun onResponse(response: JSONObject) {
            val cookies = response.cookies // Retrieve the cookies
            // Handle the response
        }

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

In the above example, we make a GET request and retrieve the cookies from the response using the cookies property of the ANResponse class.

Updating Cookies

To update cookies using Fast Networking Library, you can use the AndroidNetworking class and the Cookie class. Here's an example:

val newCookie = Cookie.Builder()
    .name("sessionid")
    .value("new_value")
    .build()

AndroidNetworking.get("https://example.com/api/data")
    .addCookie(newCookie)
    .build()
    .getAsJSONObject(object : JSONObjectRequestListener {
        override fun onResponse(response: JSONObject) {
            // Handle the response
        }

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

In the above example, we create a new Cookie object with the name "sessionid" and the new value "new_value". We then add the new cookie to the GET request using the addCookie method.

Deleting Cookies

To delete cookies using Fast Networking Library, you can use the AndroidNetworking class and the Cookie class. Here's an example:

val expiredCookie = Cookie.Builder()
    .name("sessionid")
    .value("")
    .expiresAt(0)
    .build()

AndroidNetworking.get("https://example.com/api/data")
    .addCookie(expiredCookie)
    .build()
    .getAsJSONObject(object : JSONObjectRequestListener {
        override fun onResponse(response: JSONObject) {
            // Handle the response
        }

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

In the above example, we create a new Cookie object with the name "sessionid", an empty value, and set the expiration time to 0 to indicate that the cookie has expired. We then add the expired cookie to the GET request using the addCookie method.

Conclusion

In this tutorial, we learned how to handle cookies using the Fast Networking Library in Kotlin Android. We covered making GET and POST requests with cookies, retrieving cookies from a response, updating cookies, and deleting cookies. Fast Networking Library provides a convenient and efficient way to handle cookies in your Android applications.
