Hello everyone,
I'm making my very first Box SDK NodeJS app which should download a public non-passwrod-protected file given the public share URL. No login should be requested.
I have created the app inside the developer section and generated the proper tokens.

On the github documentation I've found this method that should be used to download a file.
https://rawgit.com/box/box-node-sdk/master/docs/jsdoc/Files.html#getReadStream
The first parameter is the `fileId` but I don't find written anywhere what this id is and where to find it if what I have is just a share link.

I've tried this code

 

var fs = require('fs'), 
    BoxSDK = require('box-node-sdk'), 
        sdk = new BoxSDK({ 
        clientID: '...', 
        clientSecret: '...' 
    }), 
    client = sdk.getAnonymousClient(),
    file_id = process.argv[2].replace(/\S*\/(\S+)$/,"$1");
    
    client.files.getReadStream(file_id, null, function(error, stream) 
    { 
        if (error) { 
            throw error; 
        }
        // write the file to disk 
        var output = fs.createWriteStream('./output/'+file_id+".zip"); //I know for sure there will only be zip files 
stream.pipe(output); 
    });

 

But running it with this command

nodejs index.js https://adrime.box.com/s/s5w7lzm4xfifmxrod9r7eeniv9nhtenk

I get this error:

Error: Unexpected API Response [404 Not Found] (not_found: "Not Found") 
at Object.module.exports.buildResponseError (/home/andrea/dev/node/box_api/node_modules/box-node-sdk/lib/util/errors.js:57:23)

at nextTickCallbackWith0Args (node.js:436:9) 
at process._tickCallback (node.js:365:13)

Of course I get that the last part of the shared link is not the id.
Can you please help me in programmatically downloading a public shared file?

Thank you in advance!

  For the moment I've used this solution:

  var fs         = require("fs"),
      request    = require("request");
  
  function downloadFile(source, target, callback)
  {
      var wr = fs.createWriteStream(target);
      
      wr.on("error", function (err) {
          callback(err);
      });
      
      wr.on("close", function (ex) {
          callback();
      });
  
      request
          .get(source)
          .on("error",function(err){
              callback(err);
          })
          .on('response', function(response) 
          {
              if((""+response.statusCode).charAt(0) != "2")
                  callback({
                          msg: "File not found: "+response.request.href, 
                          path: response.request.href,
                          toString: function(){
                              return this.msg;
                          }
                       });
          })
          .on("end", function (ex) {
              console.log("request ended");
          })
      .pipe(wr)
  }
  
  function onDownloadComplete(err)
  {
      if(err)
          throw err
      
      console.log("DOWNLOAD COMPLETE");
  }
  
  function init()
  {
      var static_url = process.argv[2].replace(/\/s\//,"/shared/static/") + ".zip";
      
      downloadFile(static_url, "./output/file.zip", onDownloadComplete);
  }
  
  init();

  Hope this will help others.

  Trying to do what you're doing.  This link shows how to get the file id.

  https://github.com/box/box-node-sdk/blob/master/docs/shared-items.md

   

  once i get the file id, I still get "not found" when trying to get the file tho.

  Just got it to work, but not with the anonymous client.  switched that line to using a developer key and it worked.  Something with anonymousclient.

   

    //var client = sdk.getAnonymousClient();

    var client = sdk.getBasicClient('');
