#include <stdio.h>

#include <stdlib.h>#define BOOL int
#define TRUE 1
#define FALSE 0/**判断字符串str1是不是str2开头*/
int is_begin_with(const char *str1, char *str2)

} /**判断链接是否包含端口*/
BOOL is_default_port(const char *url, const char *port)
{if (NULL == url){return FALSE;}		if (is_begin_with(url, "https")){//说明链接https里面包含了443端口if (strstr(url, port)){printf("url start with https and has 443 port\n");r
