【问题描述】：

我有以下字符串：

https://m.facebook.com/story.php?story_fbid=123345&id=12334&__xts__%5B0%5D=12.AboYsxZUMIF4f8fZJLZ0LVrJZJ1jxGxzsmM2lJZJ8JoGFxO1UgViHWKvUSGwxVjkzwOjfCxL-FxJY9pfgvYP6L8Kwdd4tHZl-V1OaVvl40agK3dimgois_14R0sr9rSelJ5rt0WTU5fRoHNeGv2TR3sxrewYBf2wzfMQwDKV4pV4WbLkbqFd0f1mbcpx7VjMduLhbj2MXRHO_ERg1ssEesWbCHAzvZNSmXP6LycMlYHhbaoi6m7gTpBswQR-VBkdfjk3289dfsfsdfoIgfSxaxr9oa6FATiaF2V54-QWQOKgYtuO87YzKFnNh-m_mGgVkCYIA7-YwEK10zZCmSxEtSrmWSl5ZzSXNRpMg&__tn__=%2As%2As

我需要用正则表达式提取这部分：

https://m.facebook.com/story.php?story_fbid=123345&id=12334

所以我创建了这个正则表达式（在 Python 中完美运行）

https?://(www\.|m\.)(facebook\.com)\/story\.php\?story_fbid=[0-9]+&id=[0-9]+

我已尝试将其包含在 robotsfrawework 脚本中：

*** Settings ***
Library           String

*** Variables ***
$pattern  SEPARATOR=
...  https?                          
...  ://                            
...  (www\\.|m\\.)                   
...  (facebook\\.com)                
...  /story\\.php\\?story_fbid=                         
...  [0-9]+                     
...  &id=
...  [0-9]+


*** Test Cases ***
String should match pattern
    $url=     Set Variable    https://m.facebook.com/story.php?story_fbid=123345&id=12334&__xts__%5B0%5D=12.AboYsxZUMIF4f8fZJLZ0LVrJZJ1jxGxzsmM2lJZJ8JoGFxO1UgViHWKvUSGwxVjkzwOjfCxL-FxJY9pfgvYP6L8Kwdd4tHZl-V1OaVvl40agK3dimgois_14R0sr9rSelJ5rt0WTU5fRoHNeGv2TR3sxrewYBf2wzfMQwDKV4pV4WbLkbqFd0f1mbcpx7VjMduLhbj2MXRHO_ERg1ssEesWbCHAzvZNSmXP6LycMlYHhbaoi6m7gTpBswQR-VBkdfjk3289dfsfsdfoIgfSxaxr9oa6FATiaF2V54-QWQOKgYtuO87YzKFnNh-m_mGgVkCYIA7-YwEK10zZCmSxEtSrmWSl5ZzSXNRpMg&__tn__=%2As%2As
    $matchesp=  Get lines matching regexp  $url  $pattern 
    run keyword if  $matchesp   Log To Console  OK MATCHED!

但它根本不起作用（没有给出任何匹配）。 我无法理解我做错了什么。 谢谢

【参考方案1】：

使用Get Regexp Matches 关键字代替Get Lines Matching Regexp。

Get Lines Matching Regexp 用于在多行字符串中查找特定行。

代码：

*** Settings ***
Library           String

*** Variables ***
$pattern        SEPARATOR=
...               https?
...               ://
...               (www\\.|m\\.)
...               (facebook\\.com)
...               /story\\.php\\?story_fbid=
...               [0-9]+
...               &id=
...               [0-9]+

*** Test Cases ***
String should match pattern
    $url=    Set Variable    https://m.facebook.com/story.php?story_fbid=123345&id=12334&__xts__%5B0%5D=12.AboYsxZUMIF4f8fZJLZ0LVrJZJ1jxGxzsmM2lJZJ8JoGFxO1UgViHWKvUSGwxVjkzwOjfCxL-FxJY9pfgvYP6L8Kwdd4tHZl-V1OaVvl40agK3dimgois_14R0sr9rSelJ5rt0WTU5fRoHNeGv2TR3sxrewYBf2wzfMQwDKV4pV4WbLkbqFd0f1mbcpx7VjMduLhbj2MXRHO_ERg1ssEesWbCHAzvZNSmXP6LycMlYHhbaoi6m7gTpBswQR-VBkdfjk3289dfsfsdfoIgfSxaxr9oa6FATiaF2V54-QWQOKgYtuO87YzKFnNh-m_mGgVkCYIA7-YwEK10zZCmSxEtSrmWSl5ZzSXNRpMg&__tn__=%2As%2As
    $matchesp=    Get Regexp Matches    $url    $pattern
    Log To Console    \n$matchesp

输出：
