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. | |
Public Member Functions inherited from NetworkSocketHandler | |
| 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. | |
