Answer 1

Change

r = requests.post(url, params=payload)

to

r = requests.post(url, data=payload)

params are turned into query string. In your case you got url u'https://www.icsi.in/student/Members/MemberSearch.aspx?dnn%24ctr410%24MemberSearch%24txtCpNumber=16803'

Update

Here is a simple scraper written in js that uses puppeteer .

const puppeteer = require('puppeteer');

const URL = 'https://www.icsi.in/student/Members/MemberSearch.aspx';

(async () => {
  const browser = await puppeteer.launch({
    headless: false // for debugging
  });

  const page = await browser.newPage();
  await page.goto(URL);
  await page.focus('#dnn_ctr410_MemberSearch_txtFirstName');
  page.keyboard.type('First Name');
  await page.click('#dnn_ctr410_MemberSearch_btnSearch');

  const html = await page.evaluate(() => document.body.innerHTML);

  await browser.close();
})();

Run with the following commands:

npm i puppeteer
node scraper.js
