You need to你需要
- Remove the initial
/char that invalidates the match ofhttps:///http://since/appears afterhttp删除使https://http://匹配无效的首字母/字符，因为/出现在http之后 - Remove unnecessary capturing group and
{1}quantifier删除不必要的捕获组和{1}量词 - Convert the optional capturing group into a non-capturing one.将可选的捕获组转换为非捕获组。
See this Python demo :请参阅此 Python 演示：
import re
frase = "text https://www.gamivo.com/product/sea-of-thieves-pc-xbox-one other text https://www.gamivo.com/product/fifa-21-origin-eng-pl-cz-tr"
print( re.findall(r"(?:https?://)?(?:www\.)?gamivo\.com\S*", frase) )
# => ['https://www.gamivo.com/product/sea-of-thieves-pc-xbox-one', 'https://www.gamivo.com/product/fifa-21-origin-eng-pl-cz-tr']

Try this, it will take string starting from https to single space or newline.试试这个，它将把字符串从 https 开始到单个空格或换行符。
import re
frase = "text https://www.gamivo.com/product/sea-of-thieves-pc-xbox-one other text https://www.gamivo.com/product/fifa-21-origin-eng-pl-cz-tr"
x = re.findall('(https?://(?:[^\s]*))', frase)
print(x)
# ['https://www.gamivo.com/product/sea-of-thieves-pc-xbox-one', 'https://www.gamivo.com/product/fifa-21-origin-eng-pl-cz-tr']
