Bibliographyraw.txt里面是需要查询的文件
例如：
J. Hu, L. Shen, S. Albanie, G. Sun, and A. Vedaldi, “Gather-Excite: Exploiting Feature Context in Convolutional Neural Networks.” arXiv, Jan. 12, 2019. doi: 10.48550/arXiv.1810.12348.
X. Wang, R. Girshick, A. Gupta, and K. He, “Non-local Neural Networks.” arXiv, Apr. 13, 2018. doi: 10.48550/arXiv.1711.07971.
------------------

success_bibtexs_crossref, failed_results = get_bibtex_from_crossref.get_bibtexs(raws)
返回的第一个参数为bibtex列表，第二个为没有查询到的原文献

success_bibtexs_google, failed_results = get_bibtex_from_google_scholar.get_bibtexs(failed_results)
将没有查到的文献继续使用google API查询，一般都是可以查询到了，没有文献在google scholar查询不到了吧

提示，这里返回的其实是APA格式的，在上面初始化指定，也有一个参数可以设置返回bibtex格式，例如
get_bibtex_from_google_scholar = GetBibTexFromGoogleScholar(google_scholar_api_key, GetBibTexFromGoogleScholar.APA, flag = True)
但是需要设置代理服务器，例如：
import os
import re
import requests
os.environ["http_proxy"]="127.0.0.1:7890"
os.environ["https_proxy"]="127.0.0.1:7890"

get_bibtex() 去掉s就可以了
