如何从php脚本中获取响应文本?

I'm using the fetch API to send data to a PHP script, which in turn processes it and returns a message using the exit() function. I can see this response when i open the developers tool, under the nextwork tab, but i dont know how to access this response in my javascript code. here is my javascript code:

fetch(url, {
      method: 'POST',
      body: formData,
    }).then(response => {
      if (response.status === 200) {
        console.log(this.responseText); //this is the property i'm not sure of
      }
    }).catch( (error) => {
      handleError("you are disconnected");
    });

and here is my php code:

$comment = $_POST['comment'];
$category = $_POST['category'];
$id = $_POST['id'];
if ($comment && $category && $id) {
exit("invalid");
} else ....

    What you're looking for is the body of the response. It's a readable stream though so you'll need to handle the promise.

    Example:

    fetch(url, {
      method: 'POST',
      body: formData,
    })
      .then(response => response.json()) // read the response stream as JSON
      .then(data => console.log('Here is your actual response body', data))
      ... whatever else you want to do here...
    

    In the example above, the stream is being read as JSON. For your particular use case, the text() method may be more suitable.
