    @WintermeW_twitter you could use the attributes of a request object to do that.

    Hi @an-tao
    Is it possible to remove or change content-length or content-type of response as we need to test the caching of our cnd (made by nginx)?
    In other words, I need to check the caching of my CDN for the while that there is no any cache-length on response headers and the origin server is drogon as there is no any limitation on (add/edit/remove headers on) it!
    removeHeader method was not able to remove content-length!
    I know that removing some headers like Content-Length can be dangerous but is there any solution for my problem?
    All The Best,
    Hadi

    Apologies if this has already been answered somewhere. If I wanted to do a soft restart (without killing the parent process) of an application using Drogon, how might I cleanly resume Drogon?
    It looks like drogon::app() returns a singleton and I can't find a way to reset it. I also tried to create my own instance of an HttpAppFramework object using newbut it seg faults upon deletion.

    currently you can't do that, you need to change drogon code to achieve that.

    There is no API of drogon to do that, you have to change drogon code to achieve that. please refer to the run() method of drogon::app().

    @HadiAbbasi You don't need to define a route for an empty path as it is equivalent to "/"

    When I customize the filter, the lambda function passes the fccb execution causing the program to crash

    Assertion failed: (idx < storage_.size()), function getThreadData, file IOThreadStorage.h, line 100.
    can someone help me
    please
    thank you very much

    Probably know the reason, here you need to use the synchronous execCommandSync method.

    @an-tao
    you should use the fast redis client to ensure that the storage is accessed in IO threads (not in the thread used by redis client)

    hello
    I have a problem with Trantor on Windows compiled with MSVC 2017 x64. I got the below error when running a simple TCP server using Trantor :

    ERROR SO_REUSEPORT is not supported.

    @an-tao
        TcpServer(EventLoop *loop,
                  const InetAddress &address,
                  const std::string &name,
                  bool reUseAddr = true,
                  bool reUsePort = true);
    you can set the last parameter to false

    Hello. I create controller by command: drogon_ctl create controller PingController:

    PingController.h:

     #pragma once
     #include <drogon/HttpSimpleController.h>
     using namespace drogon; 
     class PingController : public drogon::HttpSimpleController<PingController>
     {
      public:
        virtual void asyncHandleHttpRequest(const HttpRequestPtr& req, std::function<void (const HttpResponsePtr &)> &&callback) override;
        PATH_LIST_BEGIN
         PATH_ADD("/PING", Get);
        PATH_LIST_END
     };

    PingController.c:

    #include "PingController.h"
    
    void PingController::asyncHandleHttpRequest(const HttpRequestPtr& req, std::function<void (const HttpResponsePtr &)> &&callback)
    {
        // write your application logic here
    
        auto resp = HttpResponse::newHttpResponse();
        resp->setStatusCode(k200OK);
        resp->setContentTypeCode(CT_TEXT_HTML);
        resp->setBody("PONG");
        callback(resp);
    
    }

    but when I try to call http://localhost/PING i get 404 Not Found

    LOG_TRACE << "log body";

    I desire above line results a line in the log file but it doesn't.
    why?
    ( I have set the log option correctly and I run the app in the Debug mode and others log have written to log file properly.)

    @an-tao
    Did you set the log_level to TRACE?

    Hi, Why the CMake files(like DrogonUtilities.cmake) are explicitly removed in the Conan recipe? How could I use functions like drogon_create_views?

    Hello, I've got a little question regarding drogon's framework usage.
    Is there any recommended way of handling HTTP requests' authorization? (Is it maybe possible to allow filters to take parameters such as an Array of required permissions? (enum values e.g.))

    Hi
    Is it possible to automatically route paths to static html files?
    For example, make http://localhost:3000/hello serve http://localhost:3000/hello.html if the html file exists?
    P.R.
    @prothegee

    @thylacinelol
    if you configure document_root directory and add *.html files, public can access it,
    even if it's located on document_root/docs/how-to-x.html
    this is also equilevant as domain.tld[:port-if-any]/docs/how-to-y.html

    open this https://drogon.org/images/drogon-concise-white.png and look https://github.com/drogonframework/drogon-website/tree/master/content/images

    thylacinelol
    @thylacinelol
    @prothegee yep, serving files works fine - I can access the page via domain.tld[:port]/hello.html, however, I want to remove the .html, so that you can access the filehello.html via domain.tld[:port]/hello.

    hi @an-tao, we have an issue related to LOG_DEBUG macro. When we integrate our system with an external logging system which uses syslog, as syslog has same macro it is overriding. Is it possbile to use some prefix before those macros. LOG_DEBUG, LOG_ERROR etc is very common and mostly logging libraries uses them.
