Typedef Documentation

◆ HTTPRequestHandler

typedef std::function<bool(HTTPRequest* req, const std::string &)> HTTPRequestHandler

Handler for requests to a certain HTTP path.

Definition at line 43 of file httpserver.h.

Function Documentation

◆ EventBase()

struct event_base* EventBase ( )

Return evhttp event base.

This can be used by submodules to queue timers or custom events.

Definition at line 550 of file httpserver.cpp.

Here is the caller graph for this function:

◆ GetQueryParameterFromUri()

std::optional<std::string> GetQueryParameterFromUri ( const char *  uri,
const std::string &  key 
)

Get the query parameter value from request uri for a specified key, or std::nullopt if the key is not found.

If the query string contains duplicate keys, the first value is returned. Many web frameworks would instead parse this as an array of values, but this is not (yet) implemented as it is currently not needed in any of the endpoints.

Helper function for HTTPRequest::GetQueryParameter.

Parameters
[in]uriis the entire request uri
[in]keyrepresents the query parameter of which the value is returned

Definition at line 717 of file httpserver.cpp.

Here is the caller graph for this function:

◆ InitHTTPServer()

bool InitHTTPServer ( const util::SignalInterrupt interrupt)

Initialize HTTP server.

Call this before RegisterHTTPHandler or EventBase().

Definition at line 428 of file httpserver.cpp.

Here is the call graph for this function:
Here is the caller graph for this function:

◆ InterruptHTTPServer()

void InterruptHTTPServer ( )

Interrupt HTTP server threads.

Definition at line 497 of file httpserver.cpp.

Here is the call graph for this function:
Here is the caller graph for this function:

◆ RegisterHTTPHandler()

void RegisterHTTPHandler ( const std::string &  prefix,
bool  exactMatch,
const HTTPRequestHandler handler 
)

Register handler for prefix.

If multiple handlers match a prefix, the first-registered one will be invoked.

Definition at line 744 of file httpserver.cpp.

Here is the caller graph for this function:

◆ StartHTTPServer()

void StartHTTPServer ( )

Start HTTP server.

This is separate from InitHTTPServer to give users race-condition-free time to register their handlers between InitHTTPServer and StartHTTPServer.

Definition at line 486 of file httpserver.cpp.

Here is the call graph for this function:
Here is the caller graph for this function:

◆ StopHTTPServer()

void StopHTTPServer ( )

Stop HTTP server.

Definition at line 509 of file httpserver.cpp.

Here is the caller graph for this function:

◆ UnregisterHTTPHandler()

void UnregisterHTTPHandler ( const std::string &  prefix,
bool  exactMatch 
)

Unregister handler for prefix.

Definition at line 751 of file httpserver.cpp.

Here is the caller graph for this function:

◆ UpdateHTTPServerLogging()

void UpdateHTTPServerLogging ( bool  enable)

Change logging level for libevent.

Definition at line 475 of file httpserver.cpp.
