PHP获取城市天气APIUSB源码，USB调用的是微鲤的USB，2020年9月1日 10:11:07测试接口还可以正常采用。

API查询USB代码

<?php 
   function tian(){
    $city=$_GET['city'];
    $url="https://wthrcdn.etouch.cn/weather_mini?city=".$city; 
    $str = file_get_contents($url);
    $result= gzdecode($str);
    //end
    echo  $result;
   }
   tian();  
?>

USB返回数据
