Python 在nginx和uwsgi网站中获取查询字符串

我用python、uwsgi和nginx构建了一个非常小的站点。当我在web浏览器地址栏中键入

localhost:8080

时，会显示类似“hello world”的内容

接下来我将添加查询字符串处理，但不知道如何添加。例如，我希望在命令提示符中打印查询字符串。因此，地址应该是这样的

localhost:8080？abc&id=21&price=778

，查询字符串应该是这样的

abc&id=21&price=778

我不能成功。这是输出和代码：

替换

print(os.getenv("QUERY_STRING"))

…与：

print(environ['QUERY_STRING'])

print(environ['QUERY_STRING'])
