本文介绍了在谷歌应用程序引擎webapp中jinja2 autoescape的问题的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 我决定安装jinja2以与我的web应用程序一起使用,以支持autoescape功能。所以我将jinja2安装到python 2.5中,并在我的项目中创建了一个指向该目录的符号链接。它基本上工作正常。 除了当我真正尝试使用{%autoescape true%}标记时,我收到以下消息: 模板 {%autoescape true%} $ b $中的文件/Users/me/project/templates/_base.html,第1行b TemplateSyntaxError:遇到未知标签'autoescape'。 我在文档中使用标签: {%autoescape true%} stuff {{var1}} stuff {{var2}} {%endautoescape%} 在我的处理程序文件中,我正在导入相关的内容: from jinja2导入环境,FileSystemLoader,TemplateNotFound from jinja2.ext import autoescape 导入工作正常,因为它不会引发错误。我做错了什么,或者jinja2本身存在问题,比如可能在ext.py中? 更新: 我在下面尝试了sharth的建议并得到了相同的结果。这是我更新的处理程序使用他的建议。 class MainHandler(BaseHandler): def get(self): self.context ['testEscape'] ='< script type =javascript> alert(hi);< / script>' env = Environment(loader = FileSystemLoader([os.path.join(os.path.dirname(__ FILE__), '模板')]),autoescape = FALSE)模板= env.get_template( '的index.html')的含量= template.render(self.context) self.response.out.write(content) 解决方案 {%autoescape%} 标记需要Jinja 2.4或更高版本以及 jinja2.ext.autoescape 扩展程序。 env = Environment(autoescape = True,extensions = ['jinja2.ext.autoescape'],$ b $ loader = ...) I decided to install jinja2 to use with my webapp application in order to support the autoescape functionality. So I installed jinja2 into python 2.5 and created a symlink within my project to point to that directory. It's mostly working fine.EXCEPT, when I actually try to use the {% autoescape true %} tag, I get the message:File "/Users/me/project/templates/_base.html", line 1, in template {% autoescape true %}TemplateSyntaxError: Encountered unknown tag 'autoescape'.I'm using the tags as they have it in the docs:{% autoescape true %} stuff {{var1}} stuff {{var2}}{% endautoescape %}Within my handler file I'm importing the relevant stuff:from jinja2 import Environment, FileSystemLoader, TemplateNotFoundfrom jinja2.ext import autoescapeAnd the import is working fine because it's not throwing an error. Am I doing something wrong, or is there a problem with jinja2 itself, like maybe in ext.py?UPDATE:I tried sharth's suggestion below and got the same result. Here is my updated handler using his suggestion.class MainHandler(BaseHandler): def get(self): self.context['testEscape']='<script type="javascript">alert("hi");</script>' env = Environment(loader=FileSystemLoader([os.path.join(os.path.dirname(__file__), 'templates')]), autoescape=False) template = env.get_template('index.html') content = template.render(self.context) self.response.out.write(content)Again, it works fine as long as I don't use the autoescape tag. 解决方案 The {% autoescape %} tag needs Jinja 2.4 or higher and the jinja2.ext.autoescape extension loaded.env = Environment(autoescape=True, extensions=['jinja2.ext.autoescape'], loader=...) 这篇关于在谷歌应用程序引擎webapp中jinja2 autoescape的问题的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 10-29 05:10
