如题，先上代码：
//http_server.c
#include
#include
#include
#include
#include
#define PORT 8080 #define SERVER_MARK "mytest http server 0.1" void http_handle(struct evhttp_request *req, void *arg); int main() { struct event_base *base; struct evhttp *http; struct evhttp_bound_socket *handle; //创建事件处理机制 base = event_base_new(); http = evhttp_new(base); evhttp_set_gencb(http, http_handle, NULL); evhttp_set_timeout(http, 120); handle = evhttp_bind_socket_with_handle(http, "0.0.0.0", PORT); if( NULL == handle ) { fprintf(stderr, "Server http handle error\n"); return -1; } //开始事件循环 event_base_dispatch(base); evhttp_free(http); event_base_free(base); return 0; } void http_handle(struct evhttp_request *req, void *arg) { struct evbuffer *buffer = evbuffer_new(); //获取客户端请求的URI const char *uri; uri = evhttp_request_uri(req); evbuffer_add_printf(buffer, "uri = %s\n", uri); //解析URI的参数(即GET方法的参数) struct evkeyvalq params; evhttp_parse_query(uri, ms); evbuffer_add_printf(buffer, "a = %s\n", evhttp_find_header( ms, "a")); evbuffer_add_printf(buffer, "b = %s\n", evhttp_find_header( ms, "b")); //设置HTTP表头 evhttp_add_header(req->output_headers, "Server", SERVER_MARK); evhttp_add_header(req->output_headers, "Content-Type", "text/plain; charset=UTF-8"); evhttp_add_header(req->output_headers, "Connection", "close"); //返回数据 evhttp_send_reply(req, HTTP_OK, "OK", buffer); evbuffer_free(buffer); }
编译：gcc http_server.c -o http_server -levent
运行：./http_server
然后在
浏览器上输入：http://localhost:8080/ a=hello&b=world
然后页面上会出现：
uri = / a=hello&b=world
a = hello
b = world
大功告成，哈哈。
