flask render_template返回字符串的ASCII码 [英] flask render_template return ascii code for string

问题描述

"test.html"的内容为

The content of "test.html" is

{{data}}

当我使用渲染时

render_template('test.html',data=u'{"a":12,"b":34}')

结果是

{& #34;a& #34;:12,& #34;b& #34;:34} //I add whitespace between & and # for display

当我使用

render_template_string('{{data}}',data=u'{"a":12,"b":34}')

结果是

{"a":12,"b":34}

用JavaScript中的JSON.parse()处理第一个结果字符串很困难.那是烧瓶的虫子吗?还是我以错误的方式处理它?<​​/p>

It's difficult to deal with the 1st result string with JSON.parse() in JavaScript. Is that a bug of flask? Or did I deal with it in a wrong way?

推荐答案

调用render_template时，Jinja会自动转义该字符串.要停止此操作，请使用safe过滤器:

When you call render_template, Jinja automatically escapes the string. To stop that, use the safe filter:

{{ data|safe }}
