What do the chars %7D mean in an url query?
提问by Niklas
If I access my webapp with the url
如果我使用 url 访问我的 webapp
/vi/5907399890173952.html
/vi/5907399890173952.html
then it works but when I look in the log files then googlebot is trying to access a similar url which generates an exception:
然后它可以工作，但是当我查看日志文件时，googlebot 正在尝试访问一个类似的 url，它会生成一个异常：
/vi/5907399890173952.html%7D%7D
/vi/5907399890173952.html%7D%7D
what does it mean and how can it be handled as an exception? The message from python is:
这是什么意思，如何作为异常处理？来自python的消息是：

get() takes exactly 3 arguments (2 given)
The regex that I use for the url is
我用于网址的正则表达式是
('/vi/(\d+)(\.html?)?', NewHandler)
('/vi/(\d+)(\.html?)?', NewHandler)

I think I've found the leakage from a jinja2 template:
我想我发现了 jinja2 模板的泄漏：
{{scored_document.fields.0.value|safe}
{{scored_document.fields.0.value|safe}
I patched it with another }now.
我现在用另一个修补它}。

%7Dis the ASCII code for the } character, which is probably leaking through from a template...
%7D是 } 字符的 ASCII 代码，它可能是从模板中泄漏出来的......
