win10 aria2c下载器的简单使用指南,配置文件
最近几个月经常使用youtube-dl下载youtube上面的视频，因为国内的网络环境不太好，用youtube-dl经常会突然断开，并且下载速度也得不到保证，所以就想到了youtube-dl可以使用外置下载工具，其中httpie，wget，curl，还有aria2c我是知道的。httpie和aria2c这两个工具是跨平台的，不过httpie主要用途并不是下载，所以这里我们用专业的下载器aria2c。
01.帮助信息
aria2c.exe -h查看帮助信息
这里给选项的帮助信息都分好类了，十分方便查看。
aria2c.exe -h
Usage: aria2c [OPTIONS] [URI | MAGNET | TORRENT_FILE | METALINK_FILE]...
Printing options tagged with '#basic'.
See 'aria2c -h#help' to know all available tags.
Options:
-v, --version Print the version number and exit.
Tags: #basic
-h, --help[=TAG|KEYWORD] Print usage and exit.
The help messages are classified with tags. A tag
starts with "#". For example, type "--help=#http"
to get the usage for the options tagged with
"#http". If non-tag word is given, print the usage
for the options whose name includes that word.
Possible Values: #basic, #advanced, #http, #https, #ftp, #metalink, #bittorrent, #cookie, #hook, #file, #rpc, #checksum, #experimental, #deprecated, #help, #all
Default: #basic
Tags: #basic, #help
-l, --log=LOG The file name of the log file. If '-' is
specified, log is written to stdout.
Possible Values: /path/to/file, -
Tags: #basic
-d, --dir=DIR The directory to store the downloaded file.
Possible Values: /path/to/directory
Default: D:\BaiduNetdiskDownload\生放送\高倉むきASMR
Tags: #basic, #file
-o, --out=FILE The file name of the downloaded file. It is
always relative to the directory given in -d
option. When the -Z option is used, this option
will be ignored.
Possible Values: /path/to/file
Tags: #basic, #http, #ftp, #file
-s, --split=N Download a file using N connections. If more
than N URIs are given, first N URIs are used and
remaining URLs are used for backup. If less than
N URIs are given, those URLs are used more than
once so that N connections total are made
simultaneously. The number of connections to the
same host is restricted by the
--max-connection-per-server option. See also the
--min-split-size option.
Possible Values: 1-*
Default: 5
Tags: #basic, #http, #ftp
--file-allocation=METHOD Specify file allocation method.
'none' doesn't pre-allocate file space. 'prealloc'
pre-allocates file space before download begins.
This may take some time depending on the size of
the file.
If you are using newer file systems such as ext4
(with extents support), btrfs, xfs or NTFS
(MinGW build only), 'falloc' is your best
choice. It allocates large(few GiB) files
almost instantly. Don't use 'falloc' with legacy
file systems such as ext3 and FAT32 because it
takes almost same time as 'prealloc' and it
blocks aria2 entirely until allocation finishes.
'falloc' may not be available if your system
doesn't have posix_fallocate() function.
'trunc' uses ftruncate() system call or
platform-specific counterpart to truncate a file
to a specified length.
Possible Values: none, prealloc, trunc, falloc
Default: prealloc
Tags: #basic, #file
-V, --check-integrity[=true|false] Check file integrity by validating piece
hashes or a hash of entire file. This option has
effect only in BitTorrent, Metalink downloads
with checksums or HTTP(S)/FTP downloads with
--checksum option. If piece hashes are provided,
this option can detect damaged portions of a file
and re-download them. If a hash of entire file is
provided, hash check is only done when file has
been already download. This is determined by file
length. If hash check fails, file is
re-downloaded from scratch. If both piece hashes
and a hash of entire file are provided, only
piece hashes are used.
Possible Values: true, false
Default: false
Tags: #basic, #metalink, #bittorrent, #file, #checksum
-c, --continue[=true|false] Continue downloading a partially downloaded
file. Use this option to resume a download
started by a web browser or another program
which downloads files sequentially from the
beginning. Currently this option is only
applicable to http(s)/ftp downloads.
Possible Values: true, false
Default: false
Tags: #basic, #http, #ftp
-i, --input-file=FILE Downloads URIs found in FILE. You can specify
multiple URIs for a single entity: separate
URIs on a single line using the TAB character.
Reads input from stdin when '-' is specified.
Additionally, options can be specified after each
line of URI. This optional line must start with
one or more white spaces and have one option per
single line. See INPUT FILE section of man page
for details. See also --deferred-input option.
Possible Values: /path/to/file, -
Tags: #basic
-j, --max-concurrent-downloads=N Set maximum number of parallel downloads for
every static (HTTP/FTP) URL, torrent and metalink.
See also --split and --optimize-concurrent-downloads options.
Possible Values: 1-*
Default: 5
Tags: #basic
-Z, --force-sequential[=true|false] Fetch URIs in the command-line sequentially
and download each URI in a separate session, like
the usual command-line download utilities.
Possible Values: true, false
Default: false
Tags: #basic
-x, --max-connection-per-server=NUM The maximum number of connections to one
server for each download.
Possible Values: 1-16
Default: 1
Tags: #basic, #http, #ftp
-k, --min-split-size=SIZE aria2 does not split less than 2*SIZE byte range.
For example, let's consider downloading 20MiB
file. If SIZE is 10M, aria2 can split file into 2
range [0-10MiB) and [10MiB-20MiB) and download it
using 2 sources(if --split >= 2, of course).
If SIZE is 15M, since 2*15M > 20MiB, aria2 does
not split file and download it using 1 source.
You can append K or M(1K = 1024, 1M = 1024K).
Possible Values: 1048576-1073741824
Default: 20M

in a torrent, aria2 doesn't use DHT for that
download even if ``true`` is given.
Possible Values: true, false
Default: true
Tags: #basic, #bittorrent
--dht-listen-port=PORT... Set UDP listening port used by DHT(IPv4, IPv6)
and UDP tracker. Multiple ports can be specified
by using ',', for example: "6881,6885". You can
also use '-' to specify a range: "6881-6999".
',' and '-' can be used together.
Possible Values: 1024-65535
Default: 6881-6999
Tags: #basic, #bittorrent
--enable-dht6[=true|false] Enable IPv6 DHT functionality.
Use --dht-listen-port option to specify port
number to listen on. See also --dht-listen-addr6
option.
Possible Values: true, false
Default: false
Tags: #basic, #bittorrent
--dht-listen-addr6=ADDR Specify address to bind socket for IPv6 DHT.
It should be a global unicast IPv6 address of the
host.
Tags: #basic, #bittorrent
-M, --metalink-file=METALINK_FILE The file path to the .meta4 and .metalink
file. Reads input from stdin when '-' is
specified.
Possible Values: /path/to/file, -
Tags: #basic, #metalink
URI, MAGNET, TORRENT_FILE, METALINK_FILE:
You can specify multiple HTTP(S)/FTP URIs. Unless you specify -Z option, all
URIs must point to the same file or downloading will fail.
You can also specify arbitrary number of BitTorrent Magnet URIs, torrent/
metalink files stored in a local drive. Please note that they are always
treated as a separate download.
You can specify both torrent file with -T option and URIs. By doing this,
download a file from both torrent swarm and HTTP/FTP server at the same time,
while the data from HTTP/FTP are uploaded to the torrent swarm. 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.
Make sure that URI is quoted with single(') or double(") quotation if it
contains "&" or any characters that have special meaning in shell.
About the number of connections
Since 1.10.0 release, aria2 uses 1 connection per host by default and has 20MiB
segment size restriction. So whatever value you specify using -s option, it
uses 1 connection per host. To make it behave like 1.9.x, use
--max-connection-per-server=4 --min-split-size=1M.

挑几个比较有用的总结一下
-l, --log=LOG 指定日志文件，也可以是路径，指定-的场合日志输出到stdout
-d, --dir=DIR 指定下载目录，默认不指定就是程序运行的目录。
-o, --out=FILE 指定文件名
-s, --split=N 下载一个文件使用的连接数，下载的时候会显示出来（即CN，我猜是connection number），默认是5，如果这个数值大于给的资源地址（URI）数，那么就会有资源地址建立多个连接。如果这个值小于给的资源地址（URI）数，那么多余的URL作为备用地址。
对同一host地址的请求会受到 --max-connection-per-server选项的限制。
--file-allocation=METHOD 文件空间预分配方式，
支持以下几种方式： none, prealloc, trunc, falloc 默认是 prealloc
prealloc会在下载之前分配磁盘空间，花费的时间取决于文件的大小。
如果用的是比较新的文件系统比如ext4，btrfs, xfs or NTFS，最好使用falloc选项，这个方式分配几gb大小的大文件的速度很快。
但是在fat32，和ext3上面建议使用prealloc，因为falloc在这些系统上没有速度优势。
mac系统下这个选项要注释掉。
-c, --continue[=true|false] 可以继续其他下载器的未完成的下载，当然必须是连续的文件，而且只支持http（s）和ftp的下载，默认是false
-i, --input-file=FILE 这个选项是用来从文件中找URI下载的，比如你的txt文件中每行列一个下载地址，然后他就会都下载了。
-j, --max-concurrent-downloads=N 最大下载连接数，默认是5个
-Z, --force-sequential[=true|false] 强制连续性下载，默认是false
-x, --max-connection-per-server=NUM 单服务器的最大连接数，范围在1-16，默认是1
-k, --min-split-size=SIZE
-k, --min-split-size=SIZE 分块大小，aria2c下载的文件大小如果小于两倍的这个值就会选择只从一个地址下载。默认是20M ，你也可以指定K
--load-cookies=FILE 导入cookie文件，需要特殊格式，Firefox3 format and Mozilla/Firefox(1.x/2.x)/Netscape format，这里有chrome插件可以实现。
基础设置就以上这么些
03.配置文件
github上找到一份配置文件相关的项目，有比较多的star，所以就直接拿来作为参考了
由于我是在windows下使用，所以作者提供的一些shell脚本都被我注释掉了，目录也换成了windows下能用的。
注意下面有些目录要换成你自己系统上设置的目录，conf文件默认目录是%USERPROFILE%/.aria2/aria2.conf,需要自己创建，还有aria2.session文件也要事先创建好

aria2c 默认 导入配置文件的路径就是%USERPROFILE%/.aria2/aria2.session，把文件放到这里就可以了。
也可以使用--conf-path=PATH来指定别的路径，也可以用--no-conf[=true|false]选择不导入配置文件的配置。
然后关于windows下falloc执行失败的问题，因为会提示需要管理员权限。
具体会出现类似以下的错误
02/29 11:01:06 [WARN] Gaining privilege SeManageVolumePrivilege failed.
02/29 11:01:06 [WARN] --file-allocation=falloc will not work properly.
02/29 11:01:06 [WARN] File allocation (SetFileValidData) failed (cause: A required privilege is not held by the client.). File will be allocated by filling zero, which blocks whole aria2 execution. Run aria2 as an administrator or use a different file allocation method (see --file-allocation).
其实这个预分配的作用是预先分配一块连续的空间，可以有效减少磁盘碎片，也就是一个保护磁盘延长寿命的作用。
迅雷以前的下载刚开始的几分钟都是在预分配，估计就是prealloc方式，要花相当一段时间。
windows下powershell提升权限的方法比较有限，似乎只能新打开一个管理员权限的powershell，也可以用来以管理员权限运行一个进程，但是youtube-dl调用的时候不会自动给你用管理员权限运行。所以说目前我的使用场景比较合适的方式就是在管理员权限的powershell下运行
执行下面的命令就可以在管理员权限下打开一个powershell窗口
Start-Process powershell -Verb runAs
还是比较麻烦，我的使用场景不如直接考虑在右键打开管理员权限的终端。我使用的终端时windows terminal。它目前并不支持切换管理员模式的终端。相在windows terminal下打开管理员模式的powershell，只有先打开管理员模式的windows terminal，然后打开的powershell和cmd就都是管理员模式的。
github上有一个issue还在讨论，但是到现在还没有结果。所以等这个功能实装估计要好久，甚至就不会实装。
https://github.com/microsoft/terminal/issues/632
管理员模式的使用情况也比较有限，所以我这里不如就使用prealloc方式算了，反正下载的文件也不会太大，花不了太多时间。
