关于某个语法问题的正则表达式规范

Question

我不断收到这个非常烦人的错误：

E: Error parsing configuration files:
    - routes: Error loading file: while parsing a quoted scalar
          in ".magento/routes.yaml", line 14, column 1
        found unknown escape character
          in ".magento/routes.yaml", line 14, column 31

我的文件相当简单。请在下面找到它：

# The routes of the project.
#
# Each route describes how an incoming URL is going to be processed.

    #"http://{default}/":
    #    type: upstream
    #    upstream: "mymagento:php"
    
    
        http://{default}/:
            type: upstream
            redirects:
            paths:
        "^/catalogsearch/result((/)|(/\?)|(/\?[a-z])|(/\?[a-z]=))?$": { to: "https://www.example.com/", regexp: true }

我尝试过使用双引号和单引号，并且我还尝试使用 \/ 转义第 14 行第 1 列

我不确定我做错了什么，但在这一点上我正在失去情节。在这里需要帮助。提前致谢。

# The routes of the project.
#
# Each route describes how an incoming URL is going to be processed.

#"http://{default}/":
#    type: upstream
#    upstream: "mymagento:php"




   

    http://{default}/:
    type: upstream
    redirects:
    paths: ^/catalogsearch/result((/)|(/\\?)|(/\\?[a-z])|(/\\?[a- 
    z]=))?$ : { to: https:///www.example.com/, regexp: true }

反斜杠在yaml中用于转义，所以必须用另一个反斜杠转义；将\ 替换为\\，并且不要在值周围使用引号：

paths: ^/catalogsearch/result((/)|(/\\?)|(/\\?[a-z])|(/\\?[a-z]=))?$

您的 yaml 语法对我来说要么是错误的，要么是陌生的。我怀疑应该是：

http:
    type:      upstream
    redirects:
    paths:     ^/catalogsearch/result((/)|(/\\?)|(/\\?[a-z])|(/\\?[a-z]=))?$
    to:        https://www.example.com/
    regexp:    true
