from http://www./blog/archives/739.html 2013.09 Libevent 的文檔非常少, 而且示例也很奇缺, 在 Google 里一搜, 還真找不到一兩個(gè). 這里貼一個(gè)最簡單的利用 Libevent 2 HTTP 庫, 作為客戶端向服務(wù)器發(fā)起請求的例子. #include <stdio.h>
#include <stdlib.h>
#include <signal.h>
#include <unistd.h>
#include <evhttp.h>
#include <event2/event.h>
#include <event2/http.h>
#include <event2/bufferevent.h>
void http_request_done(struct evhttp_request *req, void *arg){
char buf[1024];
int s = evbuffer_remove(req->input_buffer, &buf, sizeof(buf) - 1);
buf[s] = '\0';
printf("%s", buf);
// terminate event_base_dispatch()
event_base_loopbreak((struct event_base *)arg);
}
int main(int argc, char **argv){
struct event_base *base;
struct evhttp_connection *conn;
struct evhttp_request *req;
base = event_base_new();
conn = evhttp_connection_base_new(base, NULL, "127.0.0.1", 8080);
req = evhttp_request_new(http_request_done, base);
evhttp_add_header(req->output_headers, "Host", "localhost");
//evhttp_add_header(req->output_headers, "Connection", "close");
evhttp_make_request(conn, req, EVHTTP_REQ_GET, "/index.php?id=1");
evhttp_connection_set_timeout(req->evcon, 600);
event_base_dispatch(base);
return 0;
}
