可以在nginx中进行多行登录吗?

我正在将日志发送到nginx服务器,并希望将这些日志转储到一个文件中。每次发送一个日志时,我可以使用nginxechomodule强制nginx读取主体,如下所示:

http {
    log_format log_dump '$request_body';
    server {
        listen 80 default_server;
        listen [::]:80 default_server;
        access_log /logs/dump log_dump;
        location /logs {
            echo_read_request_body;
        }
    }
}

当我一次发送一个日志时,这很好:

POST /logs HTTP/1.1
Host: www.example.com

123456 index.html was accessed by 127.0.0.1

POST /logs HTTP/1.1
Host: www.example.com

123457 favicon.ico was accessed by 127.0.0.1

但是,当我尝试批处理日志时(为了避免连接开销和HTTP头开销):

POST /logs HTTP/1.1
Host: www.example.com

123456 index.html was accessed by 127.0.0.1
123457 favicon.ico was accessed by 127.0.0.1

这是我的日志文件中显示的内容:

123456 index.html was accessed by 127.0.0.1\x0A123457 favicon.ico was accessed by 127.0.0.1

现在我的假设是,因为一个nginx日志行 一行 ,它正在对我的新行字符进行编码以确保这一点。有允许多行nginx日志的方法吗?
