insomnia how to extract the value from an input html response

58 Views Asked by Eduardo Goncalves At 13 March 2024 at 15:00

I have the following HTML and I want to extract the value from the input with a name equal to code, using insomnia.

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
        <title>Return</title>
        <script>
window.onload=function() {
    var form = document.getElementById("redirect_form");
    form.submit();
}
        </script>
    <SCRIPT type="text/javascript">
/*<![CDATA[*/ 
document.cookie = "IV_JCT=%2Foauth; path=/;secure";
/*]]>*/ 
</SCRIPT>
</head>
    <body>
      <p>Return....</p>
      <form id="redirect_form" name="redirect_form" action="https://example.com/login/callbackmfe" method="POST">
          <input type="hidden" name="code" value="yDCKqoCgXDAEdeY2d01ln43gaHerP2" />
      <input type="hidden" name="iss" value="https://example.com" />
      <input type="hidden" name="state" value="testing" />
      
      </form>
    </body>
</html>

I've already tried several ways: /html/body/input[@name='code']/@value OR (//input[@name='code'])[1]/@value

What would you be doing wrong?

It is Insomnia defect. the <html> tag need <!DOCTYPE> Declaration. If have no !DOCTYPE can't parse.

Your HTML tag missing !DOCTYPE

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

Insomnia recognized HTML tag

<!DOCTYPE html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

Save as server.js

const express = require('express');
const app = express();
// //input[@type='hidden' and @name='code']/@value
app.get('/data', (req, res) => {
    const htmlContent = `
    <!DOCTYPE html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
        <head>
            <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
            <title>Return</title>
            <script>
    window.onload=function() {
        var form = document.getElementById("redirect_form");
        form.submit();
    }
            </script>
            <script type="text/javascript">
                document.cookie = "IV_JCT=%2Foauth; path=/;secure";
            </script>
        </head>
        <body>
            <p>Return....</p>
            <form id="redirect_form" name="redirect_form" action="https://example.com/login/callbackmfe" method="POST">
                <input type="hidden" name="code" value="yDCKqoCgXDAEdeY2d01ln43gaHerP2" />
                <input type="hidden" name="iss" value="https://example.com" />
                <input type="hidden" name="state" value="testing" />
            </form>
        </body>
    </html>
    `;
    res.set('Content-Type', 'text/html');
    res.send(htmlContent);
});

app.listen(3000, () => {
    console.log('Server is running on port 3000');
});

Postman can do by this Tests script

var htmlResponse = pm.response.text();

var codeValue = htmlResponse.match(/<input type="hidden" name="code" value="([^"]+)" \/>/);
