如何从 Node.js 中的 URL 下载音频文件？

Question

How to download audio file from URL and store it in local directory? I'm using Node.js and I tried the following code:

var http = require('http');
var fs = require('fs');
var dest = 'C./test'
var url= 'http://static1.grsites.com/archive/sounds/comic/comic002.wav'
function download(url, dest, callback) {
  var file = fs.createWriteStream(dest);
  var request = http.get(url, function (response) {
    response.pipe(file);
    file.on('finish', function () {
      file.close(callback); // close() is async, call callback after close completes.
    });
    file.on('error', function (err) {
      fs.unlink(dest); // Delete the file async. (But we don't check the result)
      if (callback)
        callback(err.message);
    });
  });
}

No error occured but the file has not been found.

Duplicate of How to download a file with Node.js (without using third-party libraries)? , but here is the code specific to your question:

var http = require('http');
var fs = require('fs');

var file = fs.createWriteStream("file.wav");
var request = http.get("http://static1.grsites.com/archive/sounds/comic/comic002.wav", function(response) {
  response.pipe(file);
});

Your code is actually fine, you just don't call the download function. Try adding this to the end :

download(url, dest, function(err){
   if(err){
     console.error(err);
   }else{
     console.log("Download complete");
   }
});

Also, change the value of dest to something else, like just "test.wav" or something. 'C./test' is a bad path.

I tried it on my machine and your code works fine just adding the call and changing dest .

Here is an example using Axios with an API that may require authorization

 const Fs = require('fs'); const Path = require('path'); const Axios = require('axios'); async function download(url) { let filename = "filename"; const username = "user"; const password = "password" const key = Buffer.from(username + ':' + password).toString("base64"); const path = Path.resolve(__dirname, "audio", filename) const response = await Axios({ method: 'GET', url: url, responseType: 'stream', headers: { 'Authorization': 'Basic ' + key } }) response.data.pipe(Fs.createWriteStream(path)) return new Promise((resolve, reject) => { response.data.on('end', () => { resolve(); }) response.data.on('error', () => { reject(err); }) }) }
