nginx 位置块可以匹配 URL 查询字符串吗？

Question

可以nginx的 location块匹配URL查询字符串？

例如，哪个位置块可能匹配 HTTPGET请求

GET /git/sample-repository/info/refs?service=git-receive-pack HTTP/1.1

nginx 位置块可以匹配 URL 查询字符串吗？

简短回答：不。

长答案：如果我们只有少数这样的位置块，则有一种解决方法。

以下是需要匹配特定查询字符串的 3 个位置块的示例解决方法：

server {
  #... common definitions such as server, root

  location / {
    error_page 418 = @queryone;
    error_page 419 = @querytwo;
    error_page 420 = @querythree;

    if ( $query_string = "service=git-receive-pack" ) { return 418; }
    if ( $args ~ "service=git-upload-pack" ) { return 419; }
    if ( $arg_somerandomfield = "somerandomvaluetomatch" ) { return 420; }

    # do the remaining stuff
    # ex: try_files $uri =404;

  }

  location @queryone {
    # do stuff when queryone matches
  }

  location @querytwo {
    # do stuff when querytwo matches
  }

  location @querythree {
    # do stuff when querythree matches
  }
}

您可以使用 $query_string、$args 或 $arg_fieldname。所有人都会做这项工作。您可能在官方文档中了解更多关于error_page 的信息。

警告：请确保不要使用标准的 HTTP 代码。

我知道这个问题已经有一年多了，但最近几天我一直在为类似的问题毁掉我的大脑。我想要针对公共和私有存储库的不同身份验证和处理规则，包括推和拉。这就是我最终想到的，所以我想我会分享。我知道这if是一个棘手的指令，但这似乎对我有用：

# pattern for all repos, public or private, followed by username and reponame
location ~ ^(?:\/(private))?\/([A-Za-z0-9]+)\/([A-Za-z0-9]+)\.git(\/.*)?$ {

    # if this is a pull request
    if ( $arg_service = "git-upload-pack" ) {

        # rewrite url with a prefix
        rewrite ^ /upload$uri;

    }

    # if this is a push request
    if ( $arg_service = "git-receive-pack" ) {

        # rewrite url with a prefix
        rewrite ^ /receive$uri;

    }

}

# for pulling public repos
location ~ ^\/upload(\/([A-Za-z0-9]+)\/([A-Za-z0-9]+)\.git(\/.*)?)$ {

    # auth_basic "git";
    # ^ if you want

    # ...
    # fastcgi_pass unix:/var/run/fcgiwrap.socket;
    # ...

}

# for pushing public repos
location ~ ^\/receive(\/([A-Za-z0-9]+)\/([A-Za-z0-9]+)\.git(\/.*)?)$ {

    # auth_basic "git";
    # ^ if you want

    # ...
    # fastcgi_pass unix:/var/run/fcgiwrap.socket;
    # ...

}

# for pulling private repos
location ~ ^\/upload\/private(\/([A-Za-z0-9]+)\/([A-Za-z0-9]+)\.git(\/.*)?)$ {

    # auth_basic "git";
    # ^ if you want

    # ...
    # fastcgi_pass unix:/var/run/fcgiwrap.socket;
    # ...

}

# for pushing private repos
location ~ ^\/receive\/private(\/([A-Za-z0-9]+)\/([A-Za-z0-9]+)\.git(\/.*)?)$ {

    # auth_basic "git";
    # ^ if you want

    # ...
    # fastcgi_pass unix:/var/run/fcgiwrap.socket;
    # ...

}
