title: Getting axios data from post request in my node-js back-end
body: <p>I send a post request in my vue component file : </p>
  
  <pre><code>axios.post('/add-couple', {
      word_key: this.word_key,
      word_value: this.word_value
    })
    .then((response) =&gt; {
      this.word_key = ''
      this.word_value = ''
    })
  </code></pre>
  
  <p>And handle that in dev-server.js(using express):</p>
  
  <pre><code>app.post('/add-couple', (req,res) =&gt; {
    newCouple(req.word_key,req.word_value)
    console.log(req.word_key,req.word_value) //undefined undefined 
    res.end()
  })
  </code></pre>
  
  <p>So, i want to use word_key and word_value vars, but cant, because they're both undefined. What am i doing wrong?</p>
