How to get json from php in react native

Question

I have a PHP file. When I send category:'true' with the POST method in HTML JS, it gives me back text which I echo in PHP but with React Native it sends me an object instead. How can I solve this?

This is my code:

return fetch('http://709957ef.ngrok.io/follower/get%20json.php',{
        method:'POST',
        body:JSON.stringfy({
             category:'true'
        })
      })
        .then((response) => response.text())
        .then((responsetxt) => {
          alert(responsetxt)
        })
        .catch((error) => {
          console.error(error);
        });
    }

then you just need to access a property on it that's the value you're looking for. Not sure why response.text() returns another promise. — JohnSnow

change your code to and add async to our function.

componentDidMount = async () => {

  const response = await fetch('http://709957ef.ngrok.io/follower/get%20json.php',{
    method:'POST',
    body:JSON.stringify({
        category:'true'
    })
  })

  this.setState({
    data: response.text(),
  }, () => console.log('PHP DATA: ', this.state.data))
}
