问题描述
我目前正在使用以下location指令以及try_files来实现Restfull应用程序:
I'm currently using the following location directive along with the try_files for a restfull application:
location /branches/branchx/app/api/ {
try_files $uri $uri/ /branches/branchx/app/api/api.php$is_args$args;
}
其中branchx是我的Git分支的名称.因此，我可能有多个分支，例如:branch1，branch2等.
Where branchx is the name of my Git branch. I may therefore have multiple branches such as: branch1, branch2, etc..
因此，我需要为要创建的每个分支手动创建一个指令.
And therefore I need to manually create a directive for each and every branches I will create.
为避免此问题，我希望使用正则表达式提取分支名称，并在try_files指令中使用它.因此，我将拥有一个由单个位置管理的动态系统指令负责所有分支机构.
To avoid this issue, I'm looking to use a regular expression to extract the branch name and using it in my try_files directive. So I'd have a dynamic system managed by a single location directive taking care of all branches.
到目前为止，所有在try_files中使用正则表达式的尝试都将引发405或404错误.
All attempts to use a regex so far in the try_files end up by throwing a 405 or 404 error.
我最后一次尝试(基于@Richard Smith的回答):
My last attempt (based on @Richard Smith answer):
location ~ ^(/branches/[^/]+/app/api)/ {
try_files $uri $uri/ $1/api.php$is_args$args;
}
其中哪一个返回了405(不允许)响应，以匹配uri.
Which returned a 405 (Not Allowed) response for matching uri.
推荐答案
如果使用正则表达式location，则可以同时捕获路径.例如:
If you are using a regular expression location, you can capture the path at the same time. For example:
location ~ ^(/branches/[^/]+/app/api)/ {
try_files $uri $uri/ $1/api.php$is_args$args;
}
重要说明:从前缀location更改为正则表达式location将更改评估顺序.正则表达式location块按顺序求值，因此/branches/branchx/app/api/api.php将匹配该location块，除非放置在location ~ \.php$位置块之后.有关详细信息，请参见本文档.
Important note: Changing from a prefix location to a regular expression location will change the evaluation order. Regular expression location blocks are evaluated in order, so /branches/branchx/app/api/api.php will match this location block unless it is placed after the location ~ \.php$ location block. See this document for details.
