Jinja 2安全关键字 [英] Jinja 2 safe keyword

问题描述

在理解像{{ something.render() | safe }}这样的表达式的作用时，我遇到了一个小问题.

I have a little problem understanding what an expression like {{ something.render() | safe }} does .

据我所见，没有safe关键字，它会输出整个html文档，而不仅仅是真实内容.

From what I have seen, without the safe keyword it outputs the entire html document, not just the true content.

我想知道的是它的实际作用，作用方式.

What I would like to know, is what it actually does, how it functions .

推荐答案

safe过滤器将字符串明确标记为安全"，即，如果启用了自动转义，则不应自动转义.

The safe filter explicitly marks a string as "safe", i.e., it should not be automatically-escaped if auto-escaping is enabled.

此过滤器上的文档位于此处.

The documentation on this filter is here.

请参见手动转义部分，以了解哪些字符可以转义.

See the section on manual escaping to see which characters qualify for escaping.
