php根据IP获取所在省份-百度api接口

这里用的file_put_contents,你也可以用别的，直接怼代码：

//拼接传递的参数
    $getData = array(
        'query'    =>    '127.0.0.1',
        'resource_id'    =>    '6006',
        'oe'    =>    'UTF-8',
        'format'    =>    'json'
    );
    $getData = http_build_query($getData);
    $opts = array(
      'http'=>array(
        'method'=>"POST",
        'header'=>"Content-type:application/x-www-form-urlencoded\r\n" .
                  "Content-length:". strlen($getData) ."\r\n",
                  "content"=>$getData,
      )
    );
    //获取Ip所属位置
    $context = stream_context_create($opts);
    $fp = file_get_contents('http://opendata.baidu.com/api.php', false, $context);
    var_dump(json_decode($fp, true));

返回的数据样式为：

array (4) { ["status"]=> string(1) "0" ["t"]=> string(0) "" ["set_cache_time"]=> string(0) "" ["data"]=> array(1) { [0]=> array (15) { ["location"]=> string(31) "北京市北京市 不告诉你" ["titlecont"]=> string(14) "IP地址查询" ["origip"]=> string(14) "123.206.79.176" ["origipquery"]=> string(14) "123.206.79.176" ["showlamp"]=> string(1) "1" ["showLikeShare"]=> int(1) ["shareImage"]=> int(1) ["ExtendedLocation"]=> string(0) "" ["OriginQuery"]=> string(14) "123.206.79.176" ["tplt"]=> string(2) "ip" ["resourceid"]=> string(4) "6006" ["fetchkey"]=> string(14) "123.206.79.176" ["appinfo"]=> string(0) "" ["role_id"]=> int(0) ["disp_type"]=> int(0) } } }
