=========

|
Consider the following scenarios:
|
||
|
|
|
||
|
|
1. aria2 is running on a computer that is not locally accessible via the LAN and the files need to be copied from remote aria2 computer to the local computer
|
||
|
|
2. aria2 is running locally somewhere and setting up samba/nfs/etc is "meh"
|
||
|
|
|
||
|
|
HTTP to the rescue, already in the browser right?
|
||
|
|
|
||
|
|
Simplest way is to use a straightforward Node.js library. In the below complete prescription [send](https://github.com/pillarjs/send) will be used.
|
||
|
|
|
||
|
|
Requirements
|
||
|
|
------------
|
||
|
|
Node.js & NPM
|
||
|
|
|
||
|
|
Follow relevant section: [Installing Node.js via package manager](https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager)
|
||
|
|
|
||
|
|
Steps
|
||
|
|
-----
|
||
|
|
1. as part of configuring aria2 to make life easier you will have set the global **dir** option to something like **/home/aria2/downloads**
|
||
|
|
2. clearly this folder is owned by the user **aria2**
|
||
|
|
3. open a shell session logged in as **aria2**
|
||
|
|
4. run ```cd /home/aria2/downloads```
|
||
|
|
5. run ```npm install send```
|
||
|
|
6. run ```nano send.js``` or vi if that's your thing
|
||
|
|
7. paste the content from below **send.js**
|
||
|
|
8. save the file making changes where appropriate _(follow the comments)_
|
||
|
|
9. run ```node send.js```
|
||
|
|
10. webserver is now running on port 3000 and will serve files from the directory specified
|
||
|
|
11. to test open up http://serverip:3000 - should get a response from the webserver, 2 lines of text, any browser errors and something hasn't been done properly, check IP/PORT etc
|
||
|
|
12. go back to webui-aria2
|
||
|
|
13. go to ```Settings > Connection Settings```
|
||
|
|
14. scroll down to Direct Download and put ```http://serverip:3000/``` in base URL field _(make sure have the / on the end)_
|
||
|
|
15. now that URL has been specified all the files will be converted into clickable links
|
||
|
|
16. checkout the ```more info``` on a download and see for yourself
|
||
|
|
17. if you click on files that aren't finished downloading ```you're going to have a bad day```
|
||
|
|
|
||
|
|
### send.js
|
||
|
|
|
||
|
|
```js
|
||
|
|
var http = require('http');
|
||
|
|
var send = require('send');
|
||
|
|
var url = require('url');
|
||
|
|
|
||
|
|
var app = http.createServer(function(req, res){
|
||
|
|
// this one allows the service to fail gracefully and give some feedback
|
||
|
|
function error(err) {
|
||
|
|
res.statusCode = err.status || 500;
|
||
|
|
res.end(err.message);
|
||
|
|
}
|
||
|
|
|
||
|
|
// this just makes sure everything is downloaded and not opened in the browser
|
||
|
|
function headers(res, path, stat) {
|
||
|
|
res.setHeader('Content-Disposition', 'attachment');
|
||
|
|
}
|
||
|
|
|
||
|
|
// specify the same directory that aria2 is using to save files
|
||
|
|
// not sure exactly how windows paths should be done, see if 'c:\downloads' works..
|
||
|
|
send(req, url.parse(req.url).pathname, {root: '/home/aria2/downloads'})
|
||
|
|
.on('error', error)
|
||
|
|
.on('headers', headers)
|
||
|
|
.pipe(res);
|
||
|
|
}).listen(3000); // change this to .listen(3000,'127.0.0.1') to only respond to localhost requests then access via SSH tunnel or put stunnel in front of it etc
|
||
|
|
```
