A process in which we do extract data from a website to deal with various challenges or for information purpose this is known as web scraping. It is extraction of data from a particular medium most likely form a website. We do extract data from any website we want to complete our research on various things up to date. This process is known as website data scraping. We do use API for this purpose. Scrap API makes it quite easy for us to parse data from a website in efficient way. Scraper API is a gateway to enter and its significance can be understood by discussing it in a bit more detail.
Application Programing Interface (API)
API stands for application programing Interface. It is a simple program available on websites to make web scraping easy and effective for us. It actually allows two or more apps to communicate properly and hence makes data transfer possible. Websites which are available with API’s require a simple algorithm associated to various programing languages for extraction of data. Those websites which are not equipped with API have different and difficult mechanisms for web scraping.
Need of Web Scraping
When we are available with a business or a marketplace to deal with on daily basis, then surely we have competitors. We have to move along with market trends whether we have an online or offline business. After having a firm knowledge about market trends, we also must know that how our competitors are dealing with them. Surely if someone is running a business, it must have an online website for it to make its visibility possible on global platform. When we want to know its approach for business, we must extract data from website. This process of website data scraping is known as Web Scraping.
Methods of Scraping
As discussed earlier that website data scraping using scraper API is very beneficial when we want to access data of a website for many uses. One can develop a good habit to estimate the trends of market or competitor’s way of work before jumping into a new niche. Scope of anything online can be estimated and way to represent also can be understood. There are many ways to scrap data from a website. It may include web scraping through JAVA, API scraping python, proxy scraper method or scraping bot technique.
JAVA API Scraping
In this particular technique we will scrap data from a website using JAVA. We must have basic knowledge of JAVA for this process because when someone tries to scrap data using a programing language, one must have a complete grip upon the syntax of that language for not making any mistake while performing web scraping. Along with the basic knowledge of JAVA language, we also must be aware MVEN
What is needed?
To perform any method of website data scraping using scrap API, we always require some tools. These tools tackle with various conditions during web scraping and allows us to pass through them without gambling. When we talk about JAVA, it is rich with helping tools as well. We are available with many tools to do JAVA API Scraping. Tools for sure make our work easy enough. They make our technique, time efficient and reliable. By using these tools, our scraped data from a website becomes reliable for us to be used in future. Otherwise we may get missing or misleading information. For API scraping using this technique we do require following major tools for web scraping API using JAVA.
- Jaunt
- HTML unit
Jaunt
The first tool that is going to be mentioned by us here is Jaunt. This tool is used to extract data from any JSON or HTML page.
HTML unit
Secondly it comes HTML unit. It is most powerful tool to scrap data from a website using JAVA. It has enough backup support to perform various complex operations related to web scraping with ease.
Inspect Elements in JAVA API Scraping
For next step of the process of implementation of JAVA API Scraping, we will select a website from chrome and then we will select an object from it. By opening it’s inspect elements, we will access the html code of it.
conclusion
Web scraping API is a best method for website data extraction using API’s. It has many other methods to be implemented as well including PHP, API scraping python etc. Here we have done it with JAVA and this technique is termed as JAVA API Scraping. JAVA is a powerful tool to do web scraping but its implementation requires someone to have just and perfect knowledge about the JAVA language. If it is, then surely we have a simple, accurate and efficient way to implement Scrap API using JAVA.
