Hi, friends
I'm developing a module to connect C programs with WebServices and newly I've used OpenSSL. Actually it hasn't very difficult, although I had some problem. It's very important to set properly the method to use. I'm connecting with a JBoss HTTPs WebService and I had to set this one:
meth = TLSv1_client_method();
ctx = SSL_CTX_new (meth);
I copy bellow the main function I had used, to send the HTTP POST message, I hope it'll be usefull for you:
int sendPOST(void* sd, SSL* ssl, ;char* server, char* port, char* post, char* action, char* csoap, char *response){
int ret=0;
char msg[5000]="";
char buff[5000]="";
int err=0;
int len=0;
char header[200]="";
// Setting HTTP Headers
sprintf(msg,"POST %s HTTP/1.1\r\n", post);
sprintf(header,"Host: %s:%s\r\n", server, port);
len=strlen(msg) ;
memcpy(msg + len , header, strlen(header));
len+=strlen(header);
strcpy(header,"Content-Type: application/x-www-form-urlencoded; charset=utf-8\r\n");
memcpy(msg + len, header, strlen(header));
len+=strlen(header);
sprintf(header,"Content-Length: %d\r\n", strlen(datos));
memcpy(msg + len, header, strlen(header));
len+=strlen(header);
sprintf(header,"SOAPAction: %s\r\n\r\n",action);
memcpy(msg + len, header, strlen(header));
len+=strlen(header);
// Adding csoap
memcpy(msg + len, datos, strlen(datos));
if(sd!=NULL){
// No SSL Connections
err=send((int)sd, msg, len + strlen(datos),0);
if (err == SOCKET_ERROR) {
printf("send() failed with error: %d\n", WSAGetLastError());
closesocket((int)sd);
WSACleanup();
exit(1);
}
do {
err = recv((int)sd, buff, sizeof(buff) - 1, 0);
if ( err > 0 )
printf("Bytes received: %d\n", err);
else if ( err == 0 )
printf("Connection closed\n");
else
printf("recv failed with error: %d\n", WSAGetLastError());
} while( err > 0 );
}else{
// SSL Connections
err = SSL_write (ssl, msg, len + strlen(datos)); CHK_SSL(err);
err = SSL_read (ssl, buff, sizeof(buff) - 1);
CHK_SSL(err);
buff[err] = '\0';
SSL_shutdown (ssl);
}
strcpy(respuesta, buff);
return ret;
}
