Base socket handler for HTTP traffic. More...
#include <tcp_http.h>
Public Member Functions | |
bool | IsConnected () const |
Whether this socket is currently bound to a socket. | |
virtual NetworkRecvStatus | CloseConnection (bool error=true) |
Close the current connection; for TCP this will be mostly equivalent to Close(), but for UDP it just means the packet has to be dropped. | |
NetworkHTTPSocketHandler (SOCKET sock, HTTPCallback *callback, const char *host, const char *url, const char *data, int depth) | |
Start the querying. | |
~NetworkHTTPSocketHandler () | |
Free whatever needs to be freed. | |
![]() | |
NetworkSocketHandler () | |
Create a new unbound socket. | |
virtual | ~NetworkSocketHandler () |
Close the socket when destructing the socket handler. | |
virtual void | Close () |
Really close the socket. | |
bool | HasClientQuit () const |
Whether the current client connected to the socket has quit. | |
void | Reopen () |
Reopen the socket so we can send/receive stuff again. | |
void | SendGRFIdentifier (Packet *p, const GRFIdentifier *grf) |
Serializes the GRFIdentifier (GRF ID and MD5 checksum) to the packet. | |
void | ReceiveGRFIdentifier (Packet *p, GRFIdentifier *grf) |
Deserializes the GRFIdentifier (GRF ID and MD5 checksum) from the packet. | |
void | SendCompanyInformation (Packet *p, const struct Company *c, const struct NetworkCompanyStats *stats, uint max_len=NETWORK_COMPANY_NAME_LENGTH) |
Package some generic company information into a packet. |
Static Public Member Functions | |
static int | Connect (char *uri, HTTPCallback *callback, const char *data=NULL, int depth=0) |
Connect to the given URI. | |
static void | HTTPReceive () |
Do the receiving for all HTTP connections. |
Data Fields | |
SOCKET | sock |
The socket currently connected to. |
Private Member Functions | |
int | HandleHeader () |
Handle the header of a HTTP reply. | |
int | Receive () |
Handle receiving of HTTP data. |
Private Attributes | |
char | recv_buffer [4096] |
Partially received message. | |
int | recv_pos |
Current position in buffer. | |
int | recv_length |
Length of the data still retrieving. | |
HTTPCallback * | callback |
The callback to call for the incoming data. | |
const char * | data |
The (POST) data we might want to forward (to a redirect). | |
int | redirect_depth |
The depth of the redirection. |
