主要做php接口请求的限制
ip请求只能在国内
特殊接口请求限制
请求频繁限制
php网络请求
function ihttp_request($curl, $https = true, $method = 'GET', $header = array(), $data = null)
{$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $curl);curl_setopt($ch, CURLOPT_HTTPHEADER, $header);curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);if ($https) {curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);}if ($method == 'POST') {curl_setopt($ch, CURLOPT_POST, true);curl_setopt($ch, CURLOPT_POSTFIELDS, $data);}$content = curl_exec($ch);if ($content === false) {return "网络请求出错: " . curl_error($ch);exit();}curl_close($ch);return $content;
}先给两个 获取请求ip和输出中文json中文带unicode转utf-8的函数
//获取请求ip
function get_real_ip()
{$iipp = $_SERVER["REMOTE_ADDR"];return $iipp;
}//json中文unicode转utf-8
function unicode2Chinese($str)
{return preg_replace_callback("#\\\u([0-9a-f]{4})#i",function ($r) {return iconv('UCS-2BE', 'UTF-8', pack('H4', $r[1]));},$str);
}
再来看一下获取ip属地的函数
function getIPAddress($ip)
{if ($ip) {$get = ihttp_request("https://ip.useragentinfo.com/json?ip=" . $ip);$get = json_decode($get, true);if ($get['code'] == 200) {if ($get['country'] == "中国") {//ip正常return array("ret" => 200,"country" => $get['country'],"province" => $get['province']);} else {//ip不在国内return array("ret" => 2,"msg" => "ip验证失败","country" => $get['country'],"province" => $get['province']);}} else {//请求ip失败return array("ret" => 1,"msg" => "请求归属失败");}} else {//请求没有ipreturn array("ret" => -1,"nsg" => "暂不支持此类请求","country" => 0,"province" => 0);}
}
用file_get_contents比较方便也很快
function SS_SERVER()
{$act = empty($_GET['act']) ? "0" : $_GET['act'];$max_request = 10; //特殊接口每天最大请求次数$limitAct_congig = array("login", //这里是特殊限制接口，每天只能请求几次（像login这种接口限制 可防止别人恶意爬号）);//先获取请求ip的归属地$user_ip = get_real_ip();$user_add = getIPAddress($user_ip);if ($user_add['ret'] == 1) {exit(unicode2Chinese(json_encode(["ret" => 999,"msg" => $user_add['msg'] //请求归属失败])));} elseif ($user_add['ret'] == 2) {exit(unicode2Chinese(json_encode(["ret" => 888,"msg" => $user_add['msg'] //ip验证失败])));} elseif ($user_add['ret'] == -1) {exit(unicode2Chinese(json_encode(["ret" => 777,"msg" => $user_add['msg'] //请求没有ip])));} else {//请求ip正常，接下来判断ip请求次数if (file_exists("ipgetDay.log")) {$ipget_data = file_get_contents("ipgetDay.log");$ipget_data = json_decode($ipget_data, true);empty($ipget_data[date("Y-m-d", time())]) ? $ipget_data[date("Y-m-d", time())] = array() : $ipget_data[date("Y-m-d", time())]; //[取今日总键值]$singleday_ipget = $ipget_data[date("Y-m-d", time())]; empty($singleday_ipget[$user_ip]) ? $singleday_ipget[$user_ip] = array() : $singleday_ipget[$user_ip]; //[取用户数据键值]if ($singleday_ipget[$user_ip]) {//请求act 是否在 在接口限制内if (in_array($act, $limitAct_congig)) { //[在限制接口内，直接判断今日请求次数，不考虑频繁请求]//看看今天请求有没有超出额度if ((int)$singleday_ipget[$user_ip][$act] < $max_request) { //[今天没有超出额度]//------------------------------------------------------------------------------//empty($ipget_data[date("Y-m-d", time())][$user_ip][$act]) ? $ipget_data[date("Y-m-d", time())][$user_ip][$act] = 1 : $ipget_data[date("Y-m-d", time())][$user_ip][$act];$ipget_data[date("Y-m-d", time())][$user_ip][$act] = $ipget_data[date("Y-m-d", time())][$user_ip][$act] + 1;$ipget_data[date("Y-m-d", time())][$user_ip]['get_time'] = time();$handle = fopen('ipgetDay.log', 'w+');fwrite($handle, json_encode($ipget_data));fclose($handle);//------------------------------------------------------------------------------//return true;} elseif ((int)$singleday_ipget[$user_ip][$act] >= $max_request) { //[超出额度了]exit(unicode2Chinese(json_encode(["ret" => 9087,"act" => $act,"limit" => $max_request,"msg" => "超出请求额度"])));}//不在限制接口内，判断请求次数和时间} else {$currentTime = time(); //判断请求时间if ($currentTime - (int)$singleday_ipget[$user_ip]['get_time'] > 3) { //[在请求范围内]//------------------------------------------------------------------------------//empty($ipget_data[date("Y-m-d", time())][$user_ip][$act]) ? $ipget_data[date("Y-m-d", time())][$user_ip][$act] = 1 : $ipget_data[date("Y-m-d", time())][$user_ip][$act];$ipget_data[date("Y-m-d", time())][$user_ip][$act] = $ipget_data[date("Y-m-d", time())][$user_ip][$act] + 1;$ipget_data[date("Y-m-d", time())][$user_ip]['get_time'] = time();$handle = fopen('ipgetDay.log', 'w+');fwrite($handle, json_encode($ipget_data));fclose($handle);//------------------------------------------------------------------------------//return true;} else {exit(unicode2Chinese(json_encode(["ret" => 5609,"wait" => $currentTime - (int)$singleday_ipget[$user_ip]['get_time'],"msg" => "频繁请求过滤"])));}}} else {//------------------------------------------------------------------------------//empty($ipget_data[date("Y-m-d", time())][$user_ip][$act]) ? $ipget_data[date("Y-m-d", time())][$user_ip][$act] = 1 : $ipget_data[date("Y-m-d", time())][$user_ip][$act];$ipget_data[date("Y-m-d", time())][$user_ip][$act] = $ipget_data[date("Y-m-d", time())][$user_ip][$act] + 1;$ipget_data[date("Y-m-d", time())][$user_ip]['get_time'] = time();$handle = fopen('ipgetDay.log', 'w+');fwrite($handle, json_encode($ipget_data));fclose($handle);//------------------------------------------------------------------------------//return true;}} else {exit(unicode2Chinese(json_encode(["ret" => 666,"msg" => "sql failed!"])));}}
}
下面是完整代码，主义的是ipgetDay.log文件必须手动创建!
<?phpfunction ihttp_request($curl, $https = true, $method = 'GET', $header = array(), $data = null)
