获取真实ip
先获取真实的IP地址，也有可能用户使用了代/理或者其他的，所以不能用PHP自带的函数了，用下面这段函数来获取
//获取真实ip
function real_ip()
{
$ip = $_SERVER['REMOTE_ADDR'];
if (isset($_SERVER['HTTP_X_FORWARDED_FOR']) && preg_match_all('#d{1,3}.d{1,3}.d{1,3}.d{1,3}#s', $_SERVER['HTTP_X_FORWARDED_FOR'], $matches)) {
foreach ($matches[0] as $xip) {
if (!preg_match('#^(10|172.16|192.168).#', $xip)) {
$ip = $xip;
break;
}
}
} elseif (isset($_SERVER['HTTP_CLIENT_IP']) && preg_match('/^([0-9]{1,3}.){3}[0-9]{1,3}$/', $_SERVER['HTTP_CLIENT_IP'])) {
$ip = $_SERVER['HTTP_CLIENT_IP'];
} elseif (isset($_SERVER['HTTP_CF_CONNECTING_IP']) && preg_match('/^([0-9]{1,3}.){3}[0-9]{1,3}$/', $_SERVER['HTTP_CF_CONNECTING_IP'])) {
$ip = $_SERVER['HTTP_CF_CONNECTING_IP'];
} elseif (isset($_SERVER['HTTP_X_REAL_IP']) && preg_match('/^([0-9]{1,3}.){3}[0-9]{1,3}$/', $_SERVER['HTTP_X_REAL_IP'])) {
$ip = $_SERVER['HTTP_X_REAL_IP'];
}
return $ip;
}根据IP地址获取城市信息
这里使用百度地图的 api来获取
//根据ip地址获取城市
function get_ip_city($clientip)
{
if (isset($_SERVER['HTTP_X_FORWARDED_FOR']) && $_SERVER['HTTP_X_FORWARDED_FOR'] && strcasecmp($_SERVER['HTTP_X_FORWARDED_FOR'], $unknown)) {
$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
} elseif (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], $unknown)) {
$ip = $_SERVER['REMOTE_ADDR'];
}
$url = 'http://api.map.baidu.com/location/ip?ip=' . $ip . '&ak=zyjHt3iUKWVHB5HjQYy7th1DTbKTPcGY';
$html = file_get_contents($url);
$res = json_decode($html);
$cheng = $res->content->address_detail->province; //城市
$sheng = $res->content->address_detail->city; //省份
$city = $cheng . $sheng;
return $city;
}根据城市名称获取天气
通过上面的代码，已经获取到了IP地址和城市名称。现在获取天气，这里用的是今日头条的 api接口
//获取真实ip
$ip = get_real_ip();
//获取城市
$city = get_ip_city($ip);
//根据城市获取天气
$result = get_curl("https://www.toutiao.com/stream/widget/local_weather/data/?city={$city}");获取结果
城市我这里是随便选的。因为返回结果的内容挺长，所以这里我只截取一部分在这里展示请求结果

}然后把它转换成数组
$array = json_decode($result,true);
$weather = $array['data']['weather']['day_condition'];
echo $weather;这样就获取到了天气结果
