hi all: I am porting lwip1.30 and ucos2.86 on luminary lm3s8962. the RTOS and
stack begin work and can ping. So I want to build a sample http server on
it.the code below is my http connect task and connect process function. they
are writed referenced the httpserver-netconn.c in lwip contrib-1.30.static void
Http_Task(void *parg) { extern void http_process(struct netconn *pxNetCon);
struct netconn *pxHTTPListener, *pxNewConnection; /* Create a new tcp
connection handle */ pxHTTPListener = netconn_new( NETCONN_TCP );
netconn_bind(pxHTTPListener, NULL, 80 ); netconn_listen( pxHTTPListener );
while(1) { /* Wait for connection. */
pxNewConnection=netconn_accept(pxHTTPListener); http_process(pxNewConnection);
netconn_delete(pxNewConnection); }} extern voidhttp_process(struct netconn
*conn) { struct netbuf *inbuf; char *buf; u16_t buflen; /* Read the data
from the port, blocking if nothing yet there. We assume the request (the
part we care about) is in one netbuf */ inbuf = netconn_recv(conn); if
(netconn_err(conn) == ERR_OK) { netbuf_data(inbuf, &buf, &buflen); /*
Is this an HTTP GET command? (only check the first 5 chars, since there are
other formats for GET, and we're keeping it very simple )*/ if (buflen>=5 &&
buf[0]=='G' && buf[1]=='E' && buf[2]=='T' &&
buf[3]==' ' && buf[4]=='/' ) { /* Send the HTML header
* subtract 1 from the size, since we dont send the \0 in the string
* NETCONN_NOCOPY: our data is const static, so no need to copy it
*/ netconn_write(conn, http_html_hdr, sizeof(http_html_hdr)-1,
NETCONN_NOCOPY); /* Send our HTML page */ netconn_write(conn,
http_index_html, sizeof(http_index_html)-1, NETCONN_NOCOPY); } } /* Close
the connection (server closes in HTTP) */ netconn_close(conn); /* Delete
the buffer (netconn_recv gives us ownership, so we have to make sure to
deallocate the buffer) */ netbuf_delete(inbuf);}I use realview MDK3.24 built
the target and use lm link to debug.when my program runing I find http server
only can connect one time.and when the connect is closed the server send RST
package to web browser(MAXTHON). after this I refresh the web browser but the
server can not response for this connect request.why??
