NodeJS + Request - Access denied when requesting website
Question
I'm trying to request the html of a website using request but I keep getting an access denied error. How do I get past this? Here is the code for the function below:
const request = require('request');
function firstShoe() {
request('https://www.jdsports.co.uk/product/green-nike-vapormax/281735/', function (error, response, body) {
console.log('body:', body);
});
}
Error:
</BODY>
</HTML>
body: <HTML><HEAD>
<TITLE>Access Denied</TITLE>
</HEAD><BODY>
<H1>Access Denied</H1>
You don't have permission to access "http://www.jdsports.co.uk/product/green-nike-vapormax/281735/" on this server.<P>

</BODY>
</HTML>
Found a solution by passing the user-agent into the headers.
function firstShoe() {
var options = {
headers: {'user-agent': 'node.js'}
}
request('https://www.jdsports.co.uk/product/green-nike-vapormax/281735/', options, function (error, response, body) {
console.log(body);
message.channel.send(body);
});
}

You are getting a 403 Forbidden because that website is blocking all requests sent using non common user agents (basically they check User-Agent header). It is a very simple protection to avoid scrappers.
For example, if you send the following cURL using its standard User-Agent, the response is received perfectly:
curl -v 'https://www.jdsports.co.uk/product/green-nike-vapormax/281735/'
Nevertheless, if you repeat that request specifying a non existing User-Agent, the request is blocked:
curl -v 'https://www.jdsports.co.uk/product/green-nike-vapormax/281735/' -H 'User-Agent: StackOverflow'
