Codeigniter谷歌地图API V3地理编码不工作

我正试图使用Biostall的谷歌地图v3 API来绘制一系列地址,但当我尝试输入地址时,每次生成的Lon-Lat都是0,0。只有当我特别输入每个地址的经度和纬度时,它才有效。即使是Biostall在他的示例视频和文档中使用的条目也不起作用。我也在尝试使用地理编码缓存功能,请帮忙。

$this->load->library('googlemaps');

$config = array();
$config['zoom'] = 'auto';
$config['geocodeCaching'] = TRUE;
$config['region'] = 'US';
$config['sensor'] = FALSE;
$this->googlemaps->initialize($config);

$marker = array();
$marker['position'] = '37.429, -122.1519';
$marker['animation'] = 'DROP';
$this->googlemaps->add_marker($marker);

$marker = array();
$marker['position'] = '1600 Amphitheatre Parkway in Mountain View, Santa Clara County, California United States';
$marker['animation'] = 'DROP';
$this->googlemaps->add_marker($marker);

$data['map'] = $this->googlemaps->create_map();

echo print_r($data['map']['markers']);

标记输出:

阵列([marker_0]=>阵列([纬度]=<37.429[经度]=&t;-122.1519)[marker_1]=>数组([纬度]=>0[经度]=<0))1

这是制作的地图:

BIOSTALL的建议输出如下: 纬度:0 长度:0 错误:OVER_QUERY_LIMIT 数据位置(_L): http://maps.google.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway+in+Mountain+View%2C+Santa+Clara+County%2C+California+United+States&sensor=false&region=US
