HTTP password processing is very common. GET, POST, PUT, PATCH, DELETE, OPTIONS, and HEAD are the key HTTP most commonly used verbs used with RESTful services. HTTP GET The GET request was used to obtain information on resources and is not subject to any other means. The GET API should be malicious. This simply means that every API that makes similar requests should return the same result until the resource status of the server is changed. GET requests are made securely because they do not change the status of the resource. Example URI - HTTP GET http://www.abc.com/users HTTP POST  The HTTP POST method is used to create relevant resources. POST request methods are insecure. In this case, when two similar post requests are made, there may be two different resources related to the same informatio...

Introduction to Git and Commands

01. Introduction to Git Git is officially defined as a distributed (VCS) version Control System. It's a system that monitors changes in our project files over time. It allows us to record project changes at any time and return to a selected version of the tracked files. This method is often utilized by many to figure efficiently and collaborate on team projects, where each developer can distribute their own version of the project on their computer. Later, these individual versions of the project are also merged to suit the most version of the project. Basically, it's a hugely popular tool for coordinating parallel work and managing projects between individuals and groups. Needless to mention, knowing the way to use Git may be an important skill for any developer today - it's definitely an excellent addition to your resume! The version control system is the management of changes to document changes in computer programs, large websites, and other collections of information. T...
