~~~ //获取IP地址 $ip = $this->request->ip(); //通过IP地址获取城市 $result = file_get_contents('http://api.map.baidu.com/location/ip?ak=kC9QTUMKc5G672aVFkFQ8aQmRvEiCU0f&ip=' . $ip . '&coor=bd09ll'); //json数据转化成数组 $result = json_decode($result, true); $city_title = $result['content']['address_detail']['city']; ~~~ 结果如下图: ~~~ array(3) { ["address"] => string(34) "CN|四川|成都|None|CHINANET|0|0" ["content"] => array(3) { ["address"] => string(18) "四川省成都市" ["address_detail"] => array(6) { ["city"] => string(9) "成都市" ["city_code"] => int(75) ["district"] => string(0) "" ["province"] => string(9) "四川省" ["street"] => string(0) "" ["street_number"] => string(0) "" } ["point"] => array(2) { ["x"] => string(12) "104.06792346" ["y"] => string(11) "30.67994285" } } ["status"] => int(0) } ~~~
