What is RPA?

Robotic process automation is a form of business process automation technology based on metaphorical software robots (bots) or artificial intelligence (AI) workers. RPA robots utilize the user interface to capture data and manipulate applications just like humans do.

Let’s begin this article with a small question. Have you ever logged in to your TV or PlayStation? How was your experience? Entering your password using a remote.

In this article, I’m gonna discuss how to write and set up a custom response type for the WSO2 identity server.

For that, you need to create a new project with a handler class and a validator class.

What is IAM?

According to Wikipedia IAM is defined as “a framework of policies and technologies for ensuring that the proper people in an enterprise have the appropriate access to technology resources.” IAM is the process that is used by all over the organizations in the world to grant or deny access to users. Those users may be employees, customers or business partners, etc. In this context, access is the ability of an individual user to perform a specific task, such as view, create, remove or modify.

Why do we need IAM?

IAM plays a critical role in any enterprise security plan. In most organizations, users have access…

Did you ever enter your credentials and login to your smart TV or PlayStation? Then you might have faces frustrating experience of entering your credentials with an on-screen keyboard. What if you could log in to your device with a few taps on your mobile phone or laptop?

In my previous articles, I have described setting up Go and making HTTP requests. In this article, I will explain how to create a small web server using GoLang.

Create an HTTP listener

You can use “http.handle” function to wakeup a listener.

// HandleFunc registers the handler function for the given pattern
// in the DefaultServeMux.
// The documentation for ServeMux explains how patterns are matched.
func HandleFunc(pattern string, handler func(ResponseWriter, *Request)) {
   DefaultServeMux.HandleFunc(pattern, handler)
}

Simple example

func main() {
   http.HandleFunc("/device_authorization", deviceAuthHandler.DeviceAuthHandler)
   http.HandleFunc("/token", deviceAuthHandler.TokenHandler)
   http.ListenAndServe(":8000", nil)
}

Handlers

In your listener, you have ports and handlers. You need to handle the requests that come…

Most of the time developers have to make HTTP requests and listen to them. In this article, I’m going to explain how to do it in the Go language. To get the support of Go, you can refer to these articles,

• Quick Start With GoLang
• Hello-World With Go

Overview

The http package offers functions like Get, Post, Postform etc. The following example used POST method to send the request.

req, err := http.NewRequest("POST", "https://ayeshaj:9000/register", strings.NewReader(parm.Encode()))

Client must close the response body when he finished it.

defer resp.Body.Close()

How to add URL parameters

Most of the time, we are sending URL parameters…

Using a text editor

Open your text editor and create a new file with example.go in your Golang working directory. Write your go program and save the file. Then use this command in terminal to run your program.

Using IntelliJ idea

Go to settings →plugins and search for Go. Then install the plugin. You must use the ultimate version to get support for Go.
