javascript - Node.js - 通过请求从 Google Drive 下载文件

Question

我正在尝试使用 Node.js 和 Request 模块从 Google 云端硬盘下载文件。我从项目元数据的 webContentLink 区域获取下载链接，这些链接在我的浏览器中有效。

我的请求是这样的:

request.get({uri:item.webContentLink,headers:{authorization:'Bearer'+token}}).pipe(response);

我的回复是:

stream.js:79
dest.end();
     ^
TypeError: Object #<IncomingMessage> has no method 'end'
    at Request.onend (stream.js:79:10)
    at Request.EventEmitter.emit (events.js:117:20)

我正在使用我在这里找到的方法 https://github.com/google/google-api-nodejs-client/issues/150

如有任何帮助，我们将不胜感激。

var request = require('request');

//getting children of folder
var url = "https://www.googleapis.com/drive/v2/files/"+id+"/children?maxResults=1000&q=trashed%3Dfalse&access_token="+token;;

request.get(url, function(err,response,body){

  detailsParse = JSON.parse(body);
  //if children are .mp3 then download

  if(detailsParse.mimeType == 'audio/mpeg'){
    var file = fs.createWriteStream("./"+detailsParse.title);

                    var getDown = "https://www.googleapis.com/drive/v2/files/"+detailsParse.id+"?access_token="+token;
                    request.get(getDown, function(err,response,body){
                        if(err){console.log(err)}

                        var downParse = JSON.parse(body);
                        request.get({uri:downParse.webContentLink,headers:{authorization:'Bearer'+token}}).pipe(response);
  }


})

Answer 1

好吧，这有几个部分是错误的。首先，@fmodos 将结果传递给"file"我之前创建的流是正确的。

但是这并没有完全解决问题，因为我遇到了身份验证问题和未使用正确端点的问题，所以完整的答案在下面

var request = require('request');

//getting children of folder
var url = "https://www.googleapis.com/drive/v2/files/"+id+"/children?maxResults=1000&q=trashed%3Dfalse&access_token="+token;

request.get(url, function(err,response,body){

  detailsParse = JSON.parse(body);
  //if children are .mp3 then download

  if(detailsParse.mimeType == 'audio/mpeg'){
    var file = fs.createWriteStream("./"+detailsParse.title);

    var getDown = "https://www.googleapis.com/drive/v2/files/"+detailsParse.id+"?access_token="+token;
    request.get(getDown, function(err,response,body){
      if(err){console.log(err)}

      var downParse = JSON.parse(body);
      //****THIS NEEDS TO BE THE downloadUrl ENDPOINT AND NOT THE webContentLink endpoint

      //*****NOTICE THE SPACE AFTER Bearer WAS MISSING BEFORE
      request.get({uri:downParse.downloadUrl,headers:{authorization:'Bearer '+token}}).pipe(response);
    });
  }


});
