TCivetweb Class Reference

THttpEngine implementation, based on civetweb embedded server.

It is default kind of engine, created for THttpServer Currently v1.15 from https://github.com/civetweb/civetweb is used

Additional options can be specified:

top=foldername - name of top folder, seen in the browser
thrds=N        - use N threads to run civetweb server (default 5)
auth_file      - global authentication file
auth_domain    - domain name, used for authentication

Example:

new THttpServer("http:8080?top=MyApp&thrds=3");

For the full list of supported options see TCivetweb::Create() documentation

When auth_file and auth_domain parameters are specified, access to running http server will be possible only after user authentication, using so-call digest method. To generate authentication file, htdigest routine should be used:

[shell] htdigest -c .htdigest domain_name user

When creating server, parameters should be:

auto serv = new THttpServer("http:8080?auth_file=.htdigets&auth_domain=domain_name");

◆ Create()

Bool_t TCivetweb::Create ( const char *  args)
overridevirtual

Creates embedded civetweb server.

Parameters
argsstring with civetweb server configuration

As main argument, http port should be specified like "8090". Or one can provide combination of ipaddress and portnumber like "127.0.0.1:8090" Or one can specify unix socket name like "x/tmp/root.socket" Extra parameters like in URL string could be specified after '?' mark:

thrds=N               - there N is number of threads used by the civetweb (default is 10)
top=name              - configure top name, visible in the web browser
ssl_certificate=filename - SSL certificate, see docs/OpenSSL.md from civetweb
auth_file=filename    - authentication file name, created with htdigets utility
auth_domain=domain    - authentication domain
websocket_timeout=tm  - set web sockets timeout in seconds (default 300)
websocket_disable     - disable web sockets handling (default enabled)
bind                  - ip address to bind server socket
loopback              - bind specified port to loopback 127.0.0.1 address
debug                 - enable debug mode, server always returns html page with request info
log=filename          - configure civetweb log file
max_age=value         - configures "Cache-Control: max_age=value" http header for all file-related requests, default 3600
socket_mode=value     - configures unix socket mode, default is 0700
nocache               - try to fully disable cache control for file requests
winsymlinks=no        - do not resolve symbolic links on file system (Windows only), default true
dirlisting=no         - enable/disable directory listing for browsing filesystem (default no)

Examples of valid args values:

serv->CreateEngine("http:8080?websocket_disable");
serv->CreateEngine("http:7546?thrds=30&websocket_timeout=20");
