我想在 pyton 中创建一个简短的应用程序，能够以
G:A:Vg:javax.servlet a:javax.servlet-api v:4.0.1我做的第一次尝试是在 https://central.sonatype.com 上手动插入搜索字符串
g:javax.servlet a:javax.servlet-api v:4.0.1但我想让 python 做到这一点。所以我写了
url = "https://search.maven.org/solrsearch/select?q="
src = "g:javax.servlet a:javax.servlet-api v:4.0.1"
response = requests.get(url + src)
print(response.content)
我得到了：

如何在这里检索 POM 文件表格？
我找到了解决方案：
def download(self, g, a, v, extension="pom"):

self.g = g
self.a = a
self.v = v
url = self.gav_to_url(g, a, v, extension) # create the url from the GAV format
url = url.replace(".jar", "-sources.jar") # specify to download the source files
# the following if is not mandatory
if self.is_downloadable(url):
return self.perform_download(url) #return the downloaded file
else:
print(f"The url = {url} is not a downloadable URL")
exit(1)
return 0

filename = url.split("/")[-1]
