Question

app = Celery('myapp',
             broker='amqp://user:pass#1@localhost:5672//',
             backend='rpc://',
             include=['myapp.tasks'])

我收到此错误

ValueError：基数为10的int（）的无效文字：'pass'

这段代码不起作用，我是python的新手，而Django是否有转义序列？

我试过你“”，“”“，”＃“，”##“和”＃“，希望它能逃脱它，但它没有。

我知道＃是一个问题，因为很明显，如果我从密码中删除该字符就可以完美运行

uri的rabbitmq documentation是指RFC3986。他们有一个关于保留字符的部分，而#就是其中之一。

如果URI组件的数据与保留的数据冲突字符作为分隔符的目的，那么冲突的数据必须是在URI形成之前进行百分比编码。

根据规范，您可以将#替换为%23 - 或者只使用不包含保留字符的密码。

你是对的，但也遵循相同的RFC。 Celery (or kombu) uses urllib和urllib tells they want to match the RFC也是。

它在this line崩溃，你的密码被解释为一个端口。似乎密码里面的#强制库将密码解释为端口（由于它不能转换为int而失败）。请注意，域和端口由用户名和密码相同的字符:分隔。

以下说明了最新进展。请注意，#之后的所有内容都会被解释为您网址的片段。

>>> from urllib.parse import urlparse
>>> url = 'amqp://user:pass#1@localhost:5672//'
>>> urlparse(url)
ParseResult(scheme='amqp', netloc='user:pass', path='', params='', query='', fragment='1@localhost:5672//')

查看删除#

后会发生什么

>>> url = 'amqp://user:pass%231@localhost:5672//'
>>> urlparse(url)
ParseResult(scheme='amqp', netloc='user:pass%231@localhost:5672', path='//', params='', query='', fragment='')
>>> urlparse(url).port
5672
>>> urlparse(url).password
'pass%231'

可以正确解析网址 - 但我猜密码现在是错误的。遗憾的是，我找不到任何描述如何在URI密码中转义内容的来源。但说实话 - 这听起来很受欢迎。转义密码中的字符？我建议只选择一个没有#的密码，因为这会混淆pythons URL解析器，也很可能是其他实现。

无法在芹菜django中使用'＃'作为代理网址
