THttpServer::THttpServer | ( | const char * | engine = "civetweb:8080" | ) |
constructor
As argument, one specifies engine kind which should be created like "http:8080". One could specify several engines at once, separating them with ; like "http:8080;fastcgi:9000" One also can configure readonly flag for sniffer like "http:8080;readonly" or "http:8080;readwrite"
Also searches for JavaScript ROOT sources, which are used in web clients Typically JSROOT sources located in $ROOTSYS/etc/http directory, but one could set JSROOTSYS variable to specify alternative location

void THttpServer::ProcessRequests | ( | ) |

Bool_t THttpServer::RegisterCommand | ( | const char * | cmdname, |
const char * | method, | ||
const char * | icon = 0 |
||
) |
Register command which can be executed from web interface.
As method one typically specifies string, which is executed with gROOT->ProcessLine() method. For instance serv->RegisterCommand("Invoke","InvokeFunction()");
Or one could specify any method of the object which is already registered to the server. For instance: serv->Register("/", hpx); serv->RegisterCommand("/ResetHPX", "/hpx/->Reset()"); Here symbols '/->' separates item name from method to be executed
One could specify additional arguments in the command with syntax like arg1%, arg2% and so on. For example: serv->RegisterCommand("/ResetHPX", "/hpx/->SetTitle(\"arg1%")"); serv->RegisterCommand("/RebinHPXPY", "/hpxpy/->Rebin2D(arg1%,arg2%)"); Such parameter(s) will be requested when command clicked in the browser.
Once command is registered, one could specify icon which will appear in the browser: serv->SetIcon("/ResetHPX", "rootsys/icons/ed_execute.png");
One also can set extra property '_fastcmd', that command appear as tool button on the top of the browser tree: serv->SetItemField("/ResetHPX", "_fastcmd", "true"); Or it is equivalent to specifying extra argument when register command: serv->RegisterCommand("/ResetHPX", "/hpx/->Reset()", "button;rootsys/icons/ed_delete.png");
