I followed this sample (github.com/.../http) to try and make a http request. It is not working. Code and output attached below:
#include <zephyr.h>
#include <net/socket.h>
#include <stdio.h>
#include <string.h>
#define HTTP_HOST "google.com"
#define HTTP_PORT 80
#define RECV_BUF_SIZE 8192
char recv_buf[RECV_BUF_SIZE + 1];
int blocking_recv(int fd, uint8_t *buf, uint32_t size, uint32_t flags) {
int err;
do {
err = recv(fd, buf, size, flags);
} while (err < 0 && errno == EAGAIN);
return err;
}
int blocking_send(int fd, uint8_t *buf, uint32_t size, uint32_t flags) {
int err;
do {
err = send(fd, buf, size, flags);
} while (err < 0 && errno == EAGAIN);
return err;
}
int blocking_connect(int fd, struct sockaddr *local_addr, socklen_t len) {
int err;
do {
err = connect(fd, local_addr, len);
} while (err < 0 && errno == EAGAIN);
return err;
}
int make_req(char *data) {
struct sockaddr_in local_addr;
struct addrinfo *res;
local_addr.sin_family = AF_INET;
local_addr.sin_port = htons(0);
local_addr.sin_addr.s_addr = 0;
printk("HTTP example\n\r");
int err = getaddrinfo(HTTP_HOST, NULL, NULL, &res);
printk("getaddrinfo err: %d\n\r", err);
((struct sockaddr_in *)res->ai_addr)->sin_port = htons(HTTP_PORT);
char send_buf[] =
"GET / HTTP/1.1\r\nHost: www.google.com:80\r\nConnection: close\r\n\r\n";
int send_data_len = strlen(send_buf);
int client_fd = socket(AF_INET, SOCK_STREAM, 0);
printk("client_fd: %d\n\r", client_fd);
err = bind(client_fd, (struct sockaddr *)&local_addr,
sizeof(local_addr));
printk("bind err: %d\n\r", err);
err = blocking_connect(client_fd, (struct sockaddr *)res->ai_addr,
sizeof(struct sockaddr_in));
printk("connect err: %d\n\r", err);
int num_bytes = send(client_fd, send_buf, send_data_len, 0);
printk("send err: %d\n\r", num_bytes);
int tot_num_bytes = 0;
return err;
}
Output:
error: 0 OK HTTP example getaddrinfo err: 0 client_fd: -1 bind err: -1 connect err: -1 send err: -1
