Implement Fetch API in Nashorn!
With this Complete you will be able to Run fetch in Java with Nashorn!

Credits to the bookstore of:

nashorn-polyfill

How to install:

First you have to run the JavaScript file with Nashorn from Java lib/GlobalAPI.js and Creadores Program/Fetch API.js and then upload your code and you are ready to use the Fetch API!

How to use:

The API is Slightly different than the Browser but it does the same here an explanation:

//How to make a GET request
var requestGET = fetch("https://theurltest.com", "GET");
console.info("The page say: " + requestGET);
//It also works without putting "GET" example:
var requestGET2 = fetch("https://theurltest.com");
console.info("The page say: " + requestGET2);
//How to make POST request
var requestPOST = fetch("https://theurltest.com", "POST", JSON.stringify({
    content: "Content you send to the server, You can also obviously add more variables as you need just like Fetch!"
}));
//If the server sends a message you can receive the message!
console.info("The server says: " + requestPOST);

Here is an explanation of the Function:

In GET it is not necessary since you can use fetch("URL");

In post it is like this:

//how fetch works:
fetch(theurl, method, contentToSend);

Advanced Fetch:

specify the content type in parameter 4, and in the parameter 5 extra healders like Authorization, etc. in Json example: { Authorization: "hepi" }
