Detect SQL Injection Attacks from Multiple Text Inputs in JavaScript

In our most recent JavaScript tutorial, we established what an SQL injection attack is and demonstrated how to use an API to detect an attack in a single text input. Now for this tutorial, we will focus on how you can use an API to develop a more extensive approach and check multiple text inputs for SQL injection in batch. By incorporating this into your web application, you can automatically detect SQL injection attacks in text inputs, ensuring that no malicious attempts get through to your server.

To kick off the process in JavaScript, we will run this command to install the jQuery library:

bower install jquery

Then we can call the validation function with the following code:

var settings = {
     "url": "https://api.cloudmersive.com/validate/text-input/check/sql-injection/batch",
     "method": "POST",
     "timeout": 0,
     "headers": {
          "Content-Type": "application/json",
          "Apikey": "YOUR-API-KEY-HERE"
     },
     "data": JSON.stringify({
          "RequestItems": [
               {
                    "InputText": "<string>"
               },
               {
                    "InputText": "<string>"
               }
          ],
          "DetectionLevel": "<string>"
     }),
};
$.ajax(settings).done(function (response) {
     console.log(response);
});

The returned response will maintain the order in which the text was input to deliver easy-to-read results. If you need to retrieve an API key, you can do so for free on the Cloudmersive website; this will give you access to 800 calls/month across our entire library of APIs.
