Nginx http_accept 无法映射到用于内容协商的变量

Question

目标是使用 -

将 Content-Type 值映射到文件类型

# nginx.conf
map $http_accept $suffix {
    "~*turtle" ".ttl";
    default    "DEFAULT";
}

由 -

处理

# sites-available/site
location /ontologies {
    root /folder;
    add_header Vary Accept;
    add_header X-debug-accept "$http_accept";
    add_header X-debug-suffix "$suffix";
    try_files $uri$suffix $uri =404;
}

然而，响应总是给出-

# curl -I -H "Content-type: text/turtle" URL
http_accept = */*
suffix      = DEFAULT, which is actually (blank)

Answer 1

您的问题是访问错误header。您应该使用 $http_content_type 而不是 $http_accept

# curl -v -I -H "Content-type: text/turtle" URL
*   Trying ::1...
* Connected to localhost (::1) port 80 (#0)
> GET / HTTP/1.1
> Host: localhost
> User-Agent: curl/7.47.0
> Accept: */*
> Content-Type: text/turtle

如您所见，您通过了 Content-Type 而不是 Accept。因此，您需要根据 header 使用正确的变量。 $http_content_type 或 $http_accept
