如何使用：Bottle 路线中的冒号字符

Question

我有简单的 Bottle 路由，URL 应该包含 :（冒号）符号。 URL 应该像 /REST/item:128 或 /REST/item:89753

我的路线是

@route('/REST/item:<id:int>')
def icc(id):
    return { 'id': id }

路由运行不正常。 id 只包含来自 url id 的最后一个字符，而不是完整的 id。

如何在路由中使用:（冒号）？

Answer 1

哇，这让人困惑。

我没有时间完全了解发生了什么，但我怀疑 Bottle 的一个路由正则表达式在路由中有冒号时吃掉了太多字符。

无论如何，用反斜杠转义冒号似乎可以解决问题：

@route(r'/REST/item\:<id_:int>')  # note the "r" prefix there
def icc(id_):
    return {'id': id_}

这是一个测试请求及其响应：

=> curl -v 'http://127.0.0.1:8080/REST/item:123'
{"id": 123}

编辑：谜团solved。

Bottle currently supports two syntaxes for url wildcards: The one (since 0.10) and the :old syntax. Both are described here: http://bottlepy.org/docs/dev/routing.html

In your example, the : triggered the old syntax. The solution is to escape the colon with a backslash (as described in the SO answer). Escaping is fully implemented and works as intended, but is undocumented. This is why I leave this issue open. Pull requests for better documentation would be welcomed.
