NelmioApiDocBundle阴性path_patterns

Question

现在，我尝试用NelmioApiDocBundle在Symfony 3中创建一个API文档。到目前为止，一切都按照给定的symfony文档所描述的那样工作。

现在，我想从swagger文档中删除_error和_profiler路由。它说你可以只使用path_patterns。所以我需要在文档中写下我需要的所有路线。但我有很多不同的方法。

如果有机会创建类似这样的负面路径模式，那就太酷了。

...
    path_patterns:
        - !^/_error
        - !^/fubar

这样的事有可能吗？

Answer 1

这些是正则表达式模式，所以，是的，您应该能够匹配任何类型的模式正则表达式允许的。

请查看“查找”零长度断言，特别是负面展望，并尝试如下所示：

path_patterns:
    - ^\/((?!_error)(?!fubar).)*$

Regex101是测试和理解正则表达式的优秀工具。它将解释正则表达式的每个部分的影响如下：

^ asserts position at start of a line
\/ matches the character / literally (case sensitive)
1st Capturing Group ((?!_error)(?!fubar).)*
* Quantifier — Matches between zero and unlimited times, as many times as possible, giving back as needed (greedy)
A repeated capturing group will only capture the last iteration. Put a capturing group around the repeated group to capture all iterations or use a non-capturing group instead if you're not interested in the data
Negative Lookahead (?!_error)
Assert that the Regex below does not match
_error matches the characters _error literally (case sensitive)
Negative Lookahead (?!fubar)
Assert that the Regex below does not match
fubar matches the characters fubar literally (case sensitive)
. matches any character (except for line terminators)
$ asserts position at the end of a line
