-
crawl: [Default] Crawling the real-time updated SciHub domains website (aka, SciHub domain source) to get available SciHub domains. The SciHub domain source website url is configured in the global config file in the section[scihub.domain.updater.crawl]with the key ofscihub_domain_source. You could usescidownl config --locationto show the location of the global config file and edit it.; Global config file: global.ini ; ... [scihub.domain.updater.crawl] scihub_domain_source = http://tool.yovisun.com/scihub ; ...
An example of using
crawlmode:$ scidownl domain.update --mode crawl [INFO] | 2022/03/07 21:07:50 | Found 6 valid SciHub domains in total: ['http://sci-hub.ru', 'http://sci-hub.se', 'https://sci-hub.ru', 'https://sci-hub.st', 'http://sci-hub.st', 'https://sci-hub.se'] [INFO] | 2022/03/07 21:07:50 | Saved 6 SciHub domains to local db.
-
search：Generate combinations according to the rules of SciHub domains and search for available SciHub domains. This will take longer thancrawlmode.An example of using
searchmode:$ scidownl domain.update --mode search [INFO] | 2022/03/07 21:08:44 | # Search valid SciHub domains from 1352 urls [INFO] | 2022/03/07 21:08:48 | # Found a SciHub domain url: https://sci-hub.ru [INFO] | 2022/03/07 21:08:48 | # Found a SciHub domain url: https://sci-hub.st ... [INFO] | 2022/03/07 21:09:04 | Found 6 valid SciHub domains in total: ['https://sci-hub.ru', 'https://sci-hub.st', ...] [INFO] | 2022/03/07 21:09:04 | Saved 6 SciHub domains to local db.
SciDownl use SQLite as the local database to store all updated SciHub domains locally. You can list all saved SciHub domains with the command domain.list.
$ scidownl domain.list
+--------------------+----------------+---------------+
| Url | SuccessTimes | FailedTimes |
|--------------------+----------------+---------------|
| http://sci-hub.ru | 0 | 0 |
| https://sci-hub.ru | 0 | 0 |
| https://sci-hub.st | 0 | 0 |
| http://sci-hub.st | 0 | 0 |
| https://sci-hub.se | 0 | 0 |
| http://sci-hub.se | 0 | 0 |
+--------------------+----------------+---------------+In addition to the easy-to-understand Url column, the SuccessTimes column is used to record the number of successful paper downloads using this Url, and the FailedTimes column is used to record the number of failed paper downloads using this Url. These two columns are used to calculate the priority of choosing a SciHub domain when downloading papers.
$ scidownl download --help
Usage: scidownl download [OPTIONS]
Download paper(s) by DOI or PMID.
Options:
-d, --doi TEXT DOI string. Specifying multiple DOIs is supported,
e.g., --doi FIRST_DOI --doi SECOND_DOI ...
-p, --pmid INTEGER PMID numbers. Specifying multiple PMIDs is supported,
e.g., --pmid FIRST_PMID --pmid SECOND_PMID ...
-t, --title TEXT Title string. Specifying multiple titles is
supported, e.g., --title FIRST_TITLE --title
SECOND_TITLE ...
-o, --out TEXT Output directory or file path, which could be an
absolute path or a relative path. Output directory
examples: /absolute/path/to/download/,
./relative/path/to/download/, Output file examples:
/absolute/dir/paper.pdf, ../relative/dir/paper.pdf.
If --out is not specified, paper will be downloaded
to the current directory with the file name of the
paper's title. If multiple DOIs or multiple PMIDs are
provided, the --out option is always considered as
the output directory, rather than the output file
path.
-u, --scihub-url TEXT Scihub domain url. If not specified, automatically
choose one from local saved domains. It's recommended
to leave this option empty.
-h, --help Show this message and exit.
Using option -d or --doi to download papers with DOI, option -p or --pmid to download papers with PMID,
and option -t or --title to download papers with titles. You can specify these options for multiple times, and even mix of them.
# with a single DOI
$ scidownl download --doi https://doi.org/10.1145/3375633
# with multiple DOIs
$ scidownl download --doi https://doi.org/10.1145/3375633 --doi https://doi.org/10.1145/2785956.2787496
# with a single PMID
$ scidownl download --pmid 31395057
# with multiple PMIDs
$ scidownl download --pmid 31395057 --pmid 24686414
# with a single title
$ scidownl download --title "ImageNet Classification with Deep Convolutional Neural Networks"
# with multiple titles
$ scidownl download --title "ImageNet Classification with Deep Convolutional Neural Networks" --title "Aggregated residual transformations for deep neural networks"
# with a mix of DOIs and PMIDs
$ scidownl download --doi https://doi.org/10.1145/3375633 --pmid 31395057 --pmid 24686414By default, the downloaded paper is named by the paper's title. With option -o or --out，you can customize the output location of downloaded papers, whcih could be an absolute path or a relative path, and a direcotry or a file path.
-
Output the paepr to a directory:
$ scidownl download --pmid 31395057 --out /absolute/path/of/a/directory/ # NOTE that the '/' at the end of the directory path is required, otherwise the last segment will be treated as the filename rather than a directory. $ scidownl download --pmid 31395057 --out ../relative/path/of/a/directory/ # The '/' at the end of the directory path is required too.
-
Output the paper with the file path.
$ scidownl download --pmid 31395057 --out /absolute/dir/paper.pdf $ scidownl download --pmid 31395057 --out ../relative/dir/paper.pdf $ scidownl download --pmid 31395057 --out relative/dir/paper.pdf $ scidownl download --pmid 31395057 --out paper # will be downlaoded as ./paper.pdf
NOTE that if there are more than one papers to be downloaded, the value of the --out option will always be considered as a directory, rather than a file path.
$ scidownl download --pmid 31395057 --pmid 24686414 --out paper
# will be downloaded to ./paper/ directory:
# ./paper/<paper-title-1>.pdf
# ./paper/<paper-title-2>.pdfIf some directories in the option are not exist, SciDownl will create them for you 😄.
With option -u or --scihub-url, you could use a specific SciHub url you want, rather than let SciDownl automatically choose one for you from local saved SciHub domains. It's recommended to let SciDownl choose a SciHub url, so you don't need to use this option in normal use.
$ scidownl download --pmid 31395057 --scihub-url http://sci-hub.seYou could use scihub_download function to download papers.
from scidownl import scihub_download
paper = "https://doi.org/10.1145/3375633"
paper_type = "doi"
out = "./paper/one_paper.pdf"
