语法: str = ngx.req.raw_header(no_request_line?)
环境: set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*
返回 Nginx 服务器接收到的原始 HTTP 协议头。
默认时，请求行和末尾的 CR LF 结束符也被包括在内。例如，
ngx.print(ngx.req.raw_header())输出结果类似：
GET /t HTTP/1.1
Host: localhost
Connection: close
Foo: bar
可以通过指定可选的 no_request_line 参数为 true 来去除结果中的请求行。例如，
ngx.print(ngx.req.raw_header(true))输出结果类似：
Host: localhost
Connection: close
Foo: bar
这个方法在 v0.7.17 版本中首次引入。

syntax: str = ngx.req.raw_header(no_request_line?)
context: set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*
Returns the original raw HTTP protocol header received by the Nginx server.
By default, the request line and trailing CR LF terminator will also be included. For example,
ngx.print(ngx.req.raw_header())gives something like this:
GET /t HTTP/1.1
Host: localhost
Connection: close
Foo: bar
You can specify the optional
no_request_line argument as a true value to exclude the request line from the result. For example,
ngx.print(ngx.req.raw_header(true))outputs something like this:
Host: localhost
Connection: close
Foo: bar
This method was first introduced in the v0.7.17 release.
