如何用javaScript从url中读取txt文件？

async function readTxtFileFromURL(url) {
  try {
    const response = await fetch(url);
    
    if (!response.ok) {
      throw new Error(`HTTP error! status: ${response.status}`);
    }
    
    const text = await response.text();
    console.log(text);
  } catch (error) {
    console.error('Error fetching the txt file:', error);
  }
}

const fileURL = 'https://example.com/data.txt';
readTxtFileFromURL(fileURL);

function readTxtFileFromURL(url, callback) {
  const xhr = new XMLHttpRequest();
  xhr.onreadystatechange = function() {
    if (xhr.readyState === 4) {
      if (xhr.status === 200) {
        callback(null, xhr.responseText);
      } else {
        callback(new Error(`HTTP error! status: ${xhr.status}`));
      }
    }
  };
  xhr.open('GET', url, true);
  xhr.send();
}

const fileURL = 'https://example.com/data.txt';
readTxtFileFromURL(fileURL, function(error, text) {
  if (error) {
    console.error('Error fetching the txt file:', error);
  } else {
    console.log(text);
  }
});
