Constructor & Destructor Documentation

◆ THttpServer()

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 semicolon (";"). Following engines are supported:

  http - TCivetweb, civetweb-based implementation of http protocol
  fastcgi - TFastCgi, special protocol for communicating with web servers

For each created engine one should provide socket port number like "http:8080" or "fastcgi:9000". Additional engine-specific options can be supplied with URL syntax like "http:8080?thrds=10". Full list of supported options should be checked in engines docu.

One also can configure following options, separated by semicolon:

readonly, ro   - set read-only mode (default)
readwrite, rw  - allows methods execution of registered objects
global         - scans global ROOT lists for existing objects (default)
noglobal       - disable scan of global lists
cors           - enable CORS header with origin="*"
cors=domain    - enable CORS header with origin="domain"

For example, create http server, which allows cors headers and disable scan of global lists, one should provide "http:8080;cors;noglobal" as parameter

THttpServer uses JavaScript ROOT (https://root.cern/js) to implement web clients UI. Normally JSROOT sources are used from $ROOTSYS/etc/http directory, but one could set JSROOTSYS shell variable to specify alternative location

◆ RegisterCommand()

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");

Definition at line 1036 of file THttpServer.cxx.

◆ Restrict()

void THttpServer::Restrict	(	const char *	path,

Definition at line 390 of file THttpServer.cxx.

◆ SetDrawPage()

◆ SetItemField()

Bool_t THttpServer::SetItemField	(	const char *	fullname,
		const char *	name,
		const char *	value
	)

Definition at line 1069 of file THttpServer.cxx.

◆ SetJSROOT()

void THttpServer::SetJSROOT ( const char * location )

Set location of JSROOT to use with the server One could specify address like: https://root.cern.ch/js/3.3/ http://web-docs.gsi.de/~linev/js/3.3/ This allows to get new JSROOT features with old server, reduce load on THttpServer instance, also startup time can be improved When empty string specified (default), local copy of JSROOT is used (distributed with ROOT)

Definition at line 379 of file THttpServer.cxx.

◆ SetReadOnly()

void THttpServer::SetReadOnly ( Bool_t readonly )

Set read-only mode for the server (default on) In read-only server is not allowed to change any ROOT object, registered to the server Server also cannot execute objects method via exe.json request.

Definition at line 345 of file THttpServer.cxx.

◆ SetSniffer()

void THttpServer::SetSniffer ( TRootSniffer * sniff )

Set TRootSniffer to the server Server takes ownership over sniffer.

Definition at line 325 of file THttpServer.cxx.

◆ SetTimer()

void THttpServer::SetTimer	(	Long_t	milliSec = `100`,
		Bool_t	mode = `kTRUE`
	)

create timer which will invoke ProcessRequests() function periodically Timer is required to perform all actions in main ROOT thread Method arguments are the same as for TTimer constructor By default, sync timer with 100 ms period is created

It is recommended to always use sync timer mode and only change period to adjust server reaction time. Use of async timer requires, that application regularly calls gSystem->ProcessEvents(). It happens automatically in ROOT interactive shell. If milliSec == 0, no timer will be created. In this case application should regularly call ProcessRequests() method.

Async timer allows to use THttpServer in applications, which does not have explicit gSystem->ProcessEvents() calls. But be aware, that such timer can interrupt any system call (lise malloc) and can lead to dead locks, especially in multi-threaded applications.

Definition at line 485 of file THttpServer.cxx.

inline

set name of top item in objects hierarchy

		Bool_t	can_run_immediately = `kFALSE`
	)

Submit HTTP request.

Submit http request, specified in THttpCallArg structure Contrary to ExecuteHttp, it will not block calling thread.

User should reimplement THttpCallArg::HttpReplied() method to react when HTTP request is executed. Method can be called from any thread Actual execution will be done in main ROOT thread, where analysis code is running. When called from main thread and can_run_immediately==kTRUE, will be executed immediately. Returns kTRUE when was executed.

Definition at line 610 of file THttpServer.cxx.

◆ Unregister()

Bool_t THttpServer::Unregister ( TObject * obj )

Unregister object.

Unregister object in folders hierarchy.

See TRootSniffer::UnregisterObject() for more details
