How to Check Text Input for SQL Injection (SQLI) Attacks using JavaScript

No one wants a cyber criminal interfering with their application’s SQL queries; the results of such a breach can be disastrous and lead to complete server compromise or denial-of-service. Thankfully, there’s an API to protect you from that. Our SQLI detection API is capable of detecting SQLI attacks from text input, and it can be implemented to protect your server from bad actors on the client side. The API response will provide a Boolean indicating if an SQLI attack was detected, and the original SQL query will be provided underneath that for your reference.

You can use this API for free & structure your API call using the code examples provided below in JavaScript. To get your API key, create a free account on our website (with zero commitments).

To use the built-in JavaScript XHR capability, use the following code examples:

var data = JSON.stringify("<string>");
var xhr = new XMLHttpRequest();
xhr.withCredentials = true;
xhr.addEventListener("readystatechange", function() {
     if(this.readyState === 4) {
          console.log(this.responseText);
     }
});
xhr.open("POST", "https://api.cloudmersive.com/security/threat-detection/content/sql-injection/detect/string");
xhr.setRequestHeader("Content-Type", "application/json");
xhr.setRequestHeader("Apikey", "YOUR-API-KEY-HERE");
xhr.send(data);

To begin with JQuery installation, first run the following command instead:

bower install jquery

Next, call the function:

var settings = {
     "url": "https://api.cloudmersive.com/security/threat-detection/content/sql-injection/detect/string",
     "method": "POST",
     "timeout": 0,
     "headers": {
          "Content-Type": "application/json",
          "Apikey": "YOUR-API-KEY-HERE"
     },
     "data": JSON.stringify("<string>"),
};
$.ajax(settings).done(function (response) {
     console.log(response);
});

With that, you’re all set — no more coding required. It’s that easy to boost your threat profile!
