Local Environment Setup

Create local virtual environment and clone the repository

$ virtualenv --python=python3.5 env                       # local virtual environment
$ source ./env/bin/activate                               # activate the env; use deactivate to close env
(env) $ git clone https://github.com/RonBulaon/download-now.git # CLone the repository

if you are using locally uncomment the following line in app.py bvy removing the '#' comment tag:

#if __name__ == "__main__":                 
    #app.run(host="0.0.0.0", port=80, debug=True)

above code should look like below.

if __name__ == "__main__":
    app.run(host="0.0.0.0", port=80, debug=True)

Change or create config.ini at the root directory to match new settings or other environment

 [thirdiron]
 ACCESS_TOKEN = xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx     # get this from thirdiron
 LIBRARY = xxx                                           # get this from thirdiron

 [guides]
 KEY = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx                  # generate this from springshare  
 SITE_ID = xxxx                                          # will be supplied by springshare together with the key

 [az]
 CLIENT_SECRET = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx        # generate this from springshare  
 CLIENT_ID = xxx                                         # will be supplied by springshare together with the key

Usage Notes

/geturl

Description : This service uses article title and article author to query the DOI from crossref.org. Once DOI is obtained it will send another query to ThirdIron.com to get the full text url of the article. Crossref.org can also provide the link to the article but we want to use Third Iron's because its already linked to our EZ Proxy.

Query format :

http://localhost/geturl?title=<article_title>&author=<article_author>

Sample query :

title = The Economy and Demand for Finance Ph.D.S: 1989–2001

author = DING, David K.

http://localhost/geturl?title=The Economy and Demand for Finance Ph.D.S: 1989–2001&author=DING, David K.

Expected result is in json format:

{
    "authors": "Ding, David K.; Chen, Sheng-Syan",
    "doi": "10.1016/j.ribaf.2003.12.003",
    "title": "The Economy and Demand for Finance Ph.D.S: 1989\u20132001",
    "url": "https://libkey.io/libraries/646/articles/18842023/full-text-file?utm_source=api_62"
}

You can now use the url as a link to the fulltext of the article.

Github repository of crossref.org
