FUNCTIONS

func Call(address, method string, params, reply interface{}) error

TYPES

type Client struct {
    // contains filtered or unexported fields
}

func New(uri string) *Client

func (id *Client) AddMetalink(uri string, options ...interface{}) (gid string, err error)

aria2.addMetalink(metalink[, options[, position]]) This method adds Metalink download by uploading ".metalink" file. metalink is of type base64 which contains Base64-encoded ".metalink" file. options is of type struct and its members are a pair of option name and value. See Options below for more details. If position is given as an integer starting from 0, the new download is inserted at position in the waiting queue. If position is not given or position is larger than the size of the queue, it is appended at the end of the queue. This method returns array of GID of registered download. If --rpc-save-upload-metadata is true, the uploaded data is saved as a file named hex string of SHA-1 hash of data plus ".metalink" in the directory specified by --dir option. The example of filename is 0a3893293e27ac0490424c06de4d09242215f0a6.metalink. If same file already exists, it is overwritten. If the file cannot be saved successfully or --rpc-save-upload-metadata is false, the downloads added by this method are not saved by --save-session.

func (id *Client) AddTorrent(filename string, options ...interface{}) (gid string, err error)

aria2.addTorrent(torrent[, uris[, options[, position]]]) This method adds BitTorrent download by uploading ".torrent" file. If you want to add BitTorrent Magnet URI, use aria2.addUri() method instead. torrent is of type base64 which contains Base64-encoded ".torrent" file. uris is of type array and its element is URI which is of type string. uris is used for Web-seeding. For single file torrents, URI can be a complete URI pointing to the resource or if URI ends with /, name in torrent file is added. For multi-file torrents, name and path in torrent are added to form a URI for each file. options is of type struct and its members are a pair of option name and value. See Options below for more details. If position is given as an integer starting from 0, the new download is inserted at position in the waiting queue. If position is not given or position is larger than the size of the queue, it is appended at the end of the queue. This method returns GID of registered download. If --rpc-save-upload-metadata is true, the uploaded data is saved as a file named hex string of SHA-1 hash of data plus ".torrent" in the directory specified by --dir option. The example of filename is 0a3893293e27ac0490424c06de4d09242215f0a6.torrent. If same file already exists, it is overwritten. If the file cannot be saved successfully or --rpc-save-upload-metadata is false, the downloads added by this method are not saved by --save-session.

func (id *Client) AddUri(uri string, options ...interface{}) (gid string, err error)

aria2.addUri(uris[, options[, position]]) This method adds new HTTP(S)/FTP/BitTorrent Magnet URI. uris is of type array and its element is URI which is of type string. For BitTorrent Magnet URI, uris must have only one element and it should be BitTorrent Magnet URI. URIs in uris must point to the same file. If you mix other URIs which point to another file, aria2 does not complain but download may fail. options is of type struct and its members are a pair of option name and value. See Options below for more details. If position is given as an integer starting from 0, the new download is inserted at position in the waiting queue. If position is not given or position is larger than the size of the queue, it is appended at the end of the queue. This method returns GID of registered download.

In addition to them, options listed in Input File subsection are available, except for following options: checksum, index-out, out, pause and select-file. Using log option, you can dynamically start logging or change log file. To stop logging, give empty string("") as a parameter value. Note that log file is always opened in append mode. This method returns OK for success.

func (id *Client) ChangeOption(gid string, options map[string]interface{}) (g string, err error)

aria2.changeOption(gid, options) This method changes options of the download denoted by gid dynamically. gid is of type string. options is of type struct. The following options are available for active downloads:

bt-max-peers
bt-request-peer-speed-limit
bt-remove-unselected-file
force-save
max-download-limit
max-upload-limit

For waiting or paused downloads, in addition to the above options, options listed in Input File subsection are available, except for following options: dry-run, metalink-base-uri, parameterized-uri, pause, piece-length and rpc-save-upload-metadata option. This method returns OK for success.

func (id *Client) ChangePosition(gid string, pos int, how string) (p int, err error)

aria2.changePosition(gid, pos, how) This method changes the position of the download denoted by gid. pos is of type integer. how is of type string. If how is POS_SET, it moves the download to a position relative to the beginning of the queue. If how is POS_CUR, it moves the download to a position relative to the current position. If how is POS_END, it moves the download to a position relative to the end of the queue. If the destination position is less than 0 or beyond the end of the queue, it moves the download to the beginning or the end of the queue respectively. The response is of type integer and it is the destination position.

func (id *Client) ChangeUri(gid string, fileindex int, delUris []string, addUris []string, position ...int) (p []int, err error)

aria2.changeUri(gid, fileIndex, delUris, addUris[, position]) This method removes URIs in delUris from and appends URIs in addUris to download denoted by gid. delUris and addUris are list of string. A download can contain multiple files and URIs are attached to each file. fileIndex is used to select which file to remove/attach given URIs. fileIndex is 1-based. position is used to specify where URIs are inserted in the existing waiting URI list. position is 0-based. When position is omitted, URIs are appended to the back of the list. This method first execute removal and then addition. position is the position after URIs are removed, not the position when this method is called. When removing URI, if same URIs exist in download, only one of them is removed for each URI in delUris. In other words, there are three URIs http://example.org/aria2 and you want remove them all, you have to specify (at least) 3 http://example.org/aria2 in delUris. This method returns a list which contains 2 integers. The first integer is the number of URIs deleted. The second integer is the number of URIs added.
