Here is the call graph for this function:

Member Function Documentation

std::pair< bool, std::string > HTTPRequest::GetHeader ( const std::string &  hdr)

Get the request header specified by hdr, or an empty string.

Return a pair (isPresent,string).

Definition at line 565 of file httpserver.cpp.

CService HTTPRequest::GetPeer ( )

Get CService (address:ip) for the origin of the http request.

Definition at line 635 of file httpserver.cpp.

Here is the call graph for this function:

HTTPRequest::RequestMethod HTTPRequest::GetRequestMethod ( )

Get request method.

Definition at line 654 of file httpserver.cpp.

std::string HTTPRequest::GetURI ( )

Get requested URI.

Definition at line 649 of file httpserver.cpp.

std::string HTTPRequest::ReadBody ( )

Read request body.

Note
As this consumes the underlying buffer, call this only once. Repeated calls will return an empty string.

Trivial implementation: if this is ever a performance bottleneck, internal copying can be avoided in multi-segment buffers by using evbuffer_peek and an awkward loop. Though in that case, it'd be even better to not copy into an intermediate string but use a stream abstraction to consume the evbuffer on the fly in the parsing algorithm.

Here is the caller graph for this function:

void HTTPRequest::WriteHeader ( const std::string &  hdr,
const std::string &  value 
)

Write output header.

Note
call this before calling WriteErrorReply or Reply.

Definition at line 596 of file httpserver.cpp.

Here is the caller graph for this function:

void HTTPRequest::WriteReply ( int  nStatus,
const std::string &  strReply = "" 
)

Write HTTP reply.

Closure sent to main thread to request a reply to be sent to a HTTP request.

nStatus is the HTTP status code to send. strReply is the body of the reply. Keep it empty to send a standard message.

Note
Can be called only once. As this will give the request back to the main thread, do not call any other HTTPRequest methods after calling this.

Replies must be sent in the main loop in the main http thread, this cannot be done from worker threads.
