二：根据百度地图提供的接口地址获取实际地址信息

这里以普通IP定位为例：


三，在php中的代码

function getIpAddress($ip){
        $data_info=curl("http://api.map.baidu.com/location/ip?ip=".$ip."&ak=xxxxxxxxxxxxx");
        $data_info = json_decode($data_info,true); //数据转换
        if(!isset($data_info['content'])){

			$data_info['content']['address']='内网地址127.0.0.1';

		}
        return $data_info['content']['address'];
    }
    function curl($url) {     
        $ch = curl_init();     
        curl_setopt($ch, CURLOPT_URL, $url);     
        //参数为1表示传输数据，为0表示直接输出显示。     
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);     //参数为0表示不带头文件，为1表示带头文件     
        curl_setopt($ch, CURLOPT_HEADER,0);     
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,false);     
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,false);     
        $output = curl_exec($ch);     
        curl_close($ch);     
        return $output;
    }
第二种格式：
function get_client_dizhi($ip){
	$url = 'https://api.map.baidu.com/location/ip?ak=3mOsomnzOmq0bsOqPGgx390MsHpWNfra&coor=bd09ll&ip='.$ip; 
	 
	$ch = curl_init();
	if(substr($url,0,5)=='https'){
	    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // 跳过证书检查
	    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);  // 从证书中检查SSL加密算法是否存在
	}
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
	curl_setopt($ch, CURLOPT_URL, $url);
	$response = curl_exec($ch);
	curl_close($ch);
	// $a='{"address":"CN|\u6e56\u5357\u7701|\u5cb3\u9633\u5e02|None|None|100|100","content":{"address":"\u6e56\u5357\u7701\u5cb3\u9633\u5e02","address_detail":{"adcode":"430626","city":"\u5cb3\u9633\u5e02","city_code":"220","district":"","province":"\u6e56\u5357\u7701","street":"","street_number":""},"point":{"x":"113.13548942","y":"29.36317829"}},"status":0}';
	$resArr=json_decode($response,true);
	if($resArr['status']!=0){
		return $resArr['message'];
	}
	// return $resArr;
  	return $resArr['content']['address']; 

}
