char array wont display what it reads from the connected descriptor
This is my code. accept returns the connected descriptor but in the read function the buffer(array) contains some garbage values. I am trying to capture the request made by the browser. I have configured the proxy so it will connect to the desired port. please help
#include <arpa/inet.h> #include <stdio.h> #include <time.h> #include <string.h> #include <errno.h> #include <netdb.h> #include <sys/uio.h> #include <arpa/inet.h> #include <netinet/in.h> #include <sys/types.h> #include <sys/socket.h> int main(int argc, char **argv) { int listenfd, connfd,n,x; socklen_t len; struct sockaddr_in servaddr, cliaddr; char buff[1501]; time_t ticks; int yes = 1; const char *ptr; if ( (listenfd = socket(AF_INET, SOCK_STREAM, 0)) < 0 ){ fprintf(stderr, "socket creation failed\n"); exit (1); } bzero(&servaddr, sizeof(servaddr)); servaddr.sin_family = AF_INET; if (inet_pton(AF_INET,"127.0.0.1", &servaddr.sin_addr) <= 0){ printf("inet_pton error for %s", argv[1]); return 1; } servaddr.sin_port = htons(4616); /* daytime server */ if ( (bind(listenfd, (SA *) &servaddr, sizeof(servaddr))) < 0) { fprintf(stderr, "bind failed\n"); exit (1); fprintf(stderr, "binded\n"); } if ( listen(listenfd, LISTENQ) < 0) { fprintf(stderr, "listen failed\n"); exit (1); fprintf(stderr, "listning\n"); } //for ( ; ; ) { len = sizeof(cliaddr); if ( (connfd = accept(listenfd, (SA *) &cliaddr, &len)) < 0 ) { fprintf(stderr, "accept failed\n"); exit (1); } fprintf(stdout, "accepted\n"); //} for(;;){ while ( n=read(connfd,buff,1500) > 0) { buff[n]=0; printf("%s \n",buff); if (fputs(buff, stdout) == EOF) { printf("fputs error"); return 1; } printf("[%s] \n",buff); } } if (n < 0) { printf("read error"); return 1; } if ( close(connfd) == -1) { fprintf(stderr, "accept failed\n"); exit (1); } close(listenfd); return 0; } |
Initialize the buffer with " "
char buff[1501] = " "; |
I tried., but its not working, I thing something is wrong in the read function
