title: getting request data from getInitialProps()
body: <p>I am trying to post data from a python script to a Next js server. </p>
  
  <pre><code>#python script
  import requests 
  post_data = {'username':'bob', 'id' : 32}
  # POST some form-encoded data:
  post_response = requests.post(url='http://localhost:3000/foo', data=post_data)
  </code></pre>
  
  <p>I do get a request on a server, but I do not know how to retrieve the data in getInitalProps(). I have looked at the documentation but there seems to be no such information. </p>
  
  <pre><code> static async getInitialProps({props, req})
       {
          console.log('request data: ', req.data);
        }
  </code></pre>
