Google 地图 api 地理编码不起作用

Question

我正在 CodeIgniter 中开发一个项目，我需要特定位置的 lat 和 lng。底部的代码工作正常，但现在 $geo['status'] 显示 QUERY_OVER_LIMIT。如何解决？

我还收到以下警告：

undefined offset:0 error in $latlng['lat']= $geo['results'][0]['geometry']['location']['lat']; $latlng['lng']= $geo['results'][0]['geometry']['location']['lat'];

提前致谢。这是我的代码：

$address = $this->input->post('key');
$geo = file_get_contents('http://maps.googleapis.com/maps/api/geoco/json?address='.urlencode($address).'&sensor=false');
$geo = json_decode($geo, true);

if ($geo['status'] = 'OK') {
    $latlng['lat']= $geo['results'][0]['geometry']['location']['lat'];
    $latlng['lng']= $geo['results'][0]['geometry']['location']['lat'];
    echo json_encode($latlng);
} else {
    echo 0;
}

Answer 1

首先，您对 $geo['status'] = 'OK' 的检查将始终是 'OK'，因为您使用了一个“=”而不是“==”。

这意味着即使 google 响应与您预期的不同，您仍然继续进入该代码块。

<?php

$row = [
    'address' => '1315 10th St.',
    'city'    => 'Sacramento',
    'state'   => 'CA',
    'zip'     => '95814'
];

$address = str_replace(' ', '+', $row['address'] ) . ',' 
    . str_replace(' ', '+', $row['city'] ) . ',' 
    . str_replace(' ', '+', $row['state'] ) . ',' 
    . str_replace(' ', '+', $row['zip'] );

function get_gps_coordinates_of_street_address( $address )
{
    $url = 'https://maps.googleapis.com/maps/api/geocode/json?address=' 
                    . $address;

    if( $response = @file_get_contents( $url ) )
    {
        $geo = json_decode( $response, TRUE );

        if( $geo['status'] == 'OK' )
        {
            return $geo['results'][0]['geometry']['location']['lat'] . ',' . $arr['results'][0]['geometry']['location']['lng'];
        }
        else
        {
            return 'GPS coordinates were not available for supplied ADDRESS';
        }

    }
    else
    {
        return 'GPS coordinates were not available because connection failed or malformed request';
    }
}

var_dump( get_gps_coordinates_of_street_address( $address ) );
