aria2c 继续下载
　当aria2c异常退出时，或者手动退出时，使用相同的命令就可以继续下载了。通过相同的命令重新启动aria，它将正确地恢复下载。前提是有按照aria2c.conf中保存了aria2.session.

aria2c rcp 示例
最全的说明，肯定是官方的文档　https://aria2.github.io/manual/en/html/aria2c.html
The following example adds http://example.org/file:

import urllib2, json
jsonreq = json.dumps({'jsonrpc':'2.0', 'id':'qwer',
                      'method':'aria2.addUri',
                      'params':[['http://example.org/file']]})
c = urllib2.urlopen('http://localhost:6800/jsonrpc', jsonreq)
c.read()
'{"id":"qwer","jsonrpc":"2.0","result":"2089b05ecca3d829"}'

使用curl命令行操作

curl -v -d '{"jsonrpc":"2.0", "id":"qwer","method":"aria2.addUri","params":["token:const",["http://example.org/file"]]}' http://localhost:6800/jsonrpc

{"id":"qwer","jsonrpc":"2.0","result":"6d6994d4933bd2af"}
