从捕捉道路获取结果API

需要一些帮助。所以我使用Google API Snap To Road。这里是我的代码：从捕捉道路获取结果API

<?php 
set_time_limit(0); 
$jsonarr = array(); 
$today=date("Y-m-d"); 

$ACCOUNT=$_GET['ACCOUNT']; 
$ticket_no=$_GET['ticket_no']; 
require_once("config/msdb_connect.php"); 

$query = mssql_query("SELECT * FROM TblGps WHERE DOOR = '".$ticket_no."' AND  DATETIME BETWEEN '".$today." 00:00:00' AND '".$today." 23:59:59' ORDER BY DATETIME DESC"); 
while($row = mssql_fetch_array($query)) 
{ 
    //parameters 
    $lng=$row['LONG']; 
    $lat=$row['LAT']; 
    //$data = array('lat'=>$lat,'lng'=>$lng); 
    //echo $latlng = GetArray($data); 

$jsonarr[] = array(
         'id' => $row['ID'], 
         'account' => $row['ACCOUNT'], 
         'datetime' =>date("m/d/Y  H:i:s",strtotime($row['DATETIME'])), 
         'loc' => $row['LOCATION'], 
         // 'speed' => $row['SPEED'], 
         'longi' => $lng, 
         'lat' => $lat, 
         'lac' => $row['LAC'], 
         'cid' => $row['CID'], 
         // 'engine' => $row['ENGINE'], 
         'remarks' => $row['REMARKS'] 
        ); 
} 

$path = GetArray($jsonarr); 
$snailtrail=GetSnailTrail($path); 

function GetArray($array){ 

    $stringdata = ""; 
    for($i = 0 ; $i <= count($array) - 1 ; $i++){ 
    $rows = (object)$array[$i]; 
    if($i == count($array) - 1) $stringdata .= $rows->lat.','.$rows->longi; 
    else $stringdata .= $rows->lat.','.$rows->longi.'|'; 
    } 
    return $stringdata; 
} 
function GetSnailTrail($path){ 
    $key='AIzaSyDRlfacNyHn7ZOsC0FzufqZ_rtQYfZD6wA'; 
    $url='https://roads.googleapis.com/v1/snapToRoads?path='.$path.'&interpolate=true&key='.$key.' '; 

    $curl = curl_init(); 
    curl_setopt($curl, CURLOPT_URL, $url); 
    curl_setopt($curl, CURLOPT_CUSTOMREQUEST,"POST"); 
    // curl_setopt($curl, CURLOPT_POSTFIELDS, $json); 
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); 
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); 

    $api_response = curl_exec($curl); 
    curl_close($curl); 
    $result = json_decode($api_response); 

    $result = (object)$result; 
    $result = (object)$result->location; 

    return $result; 
    }

所以我从我的DATABSE获取经度和纬度。然后，我将使用我的函数GetArray将其组合为GetSnailTrail函数中参数路径的多个记录。

因此，这将是这个样子的发送API之前：

https://roads.googleapis.com/v1/snapToRoads?path=14.567467,121.030726|14.566950,121.030497|14.567447,121.031204|14.566947,121.030520|14.566947,121.030520|14.567590,121.031181|14.567590,121.031181|14.567377,121.031236|14.566947,121.030520|14.567447,121.031204|14.566947,121.030520|14.566947,121.030520|14.566947,121.030520|14.566947,121.030520|14.567590,121.031181|14.567377,121.031236|14.567447,121.031204|14.567377,121.031236|14.567377,121.031236|14.567377,121.031236|14.567377,121.031236|14.567377,121.031236|14.567377,121.031236|14.567590,121.031181|14.567377,121.031236|14.567590,121.031181|14.567377,121.031236|14.567447,121.031204|14.567377,121.031236|14.567447,121.031204|14.567377,121.031236|14.567466,121.030726|14.567377,121.031236|14.567377,121.031236|14.567377,121.031236|14.567447,121.031204|14.567377,121.031236|14.567056,121.030569|14.567012,121.030539|14.567049,121.030568|14.567009,121.030545|14.567468,121.030728|14.567031,121.030549|14.567007,121.030545|14.567098,121.030403|14.567037,121.030548|14.567178,121.030624|14.566899,121.030486|14.566946,121.030520|14.567056,121.030569|14.567056,121.030569|14.567056,121.030569|14.566946,121.030520|14.566947,121.030522|14.566947,121.030522|14.566947,121.030522|14.567103,121.030594|14.566946,121.030520|14.566947,121.030522|14.566947,121.030524|14.567028,121.030556|14.566780,121.030502|14.566780,121.030502|14.567103,121.030594|14.567103,121.030594|14.566947,121.030522|14.566946,121.030520|14.566946,121.030520|14.566946,121.030520|14.566947,121.030524|14.566947,121.030524&interpolate=true&key=AIzaSyDRlfacNyHn7ZOsC0FzufqZ_rtQYfZD6wA

后，该API将返回这样的结果：

{ 
    "snappedPoints": [ 
    { 
     "location": { 
     "latitude": 14.567361300000002, 
     "longitude": 121.03068420000001 
     }, 
     "originalIndex": 0, 
     "placeId": "ChIJF6oagKzJlzMRlFWOLr4F1SI" 
}

出于某种原因，我不能呼应或获得在我的$jsonarr上输入它的响应。得到回应后该怎么办？谢谢

卷曲没有提供任何错误？请参阅：[curl_error]（http://php.net/manual/en/function.curl-error.php）。和'var_dump（$ api_response）'。 – Jigar

是的，它显示411错误 –

给出的URL和相关数据返回浏览器来访问返回的数据的每一部分我发现这个工作确定，假设$data分配来自卷边请求的响应。

curl请求是使用GET而不是POST和在函数之外解码的响应完成的。以前你的代码试图访问$result->location〜而应该是$result->snappedPoints

function GetSnailTrail($path=false){ 
     if(!$path)return false; 
     $key='AIzaSyDRlfacNyHn7ZOsC0FzufqZ_rtQYfZD6wA';

     curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); 
     curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); 

     $result = curl_exec($curl); 
     curl_close($curl); 

     return $result; 
    } 

    $path='14.567467,121.030726|14.566950,121.030497|14.567447,121.031204|14.566947,121.030520|14.566947,121.030520|14.567590,121.031181|14.567590,121.031181|14.567377,121.031236|14.566947,121.030520|14.567447,121.031204|14.566947,121.030520|14.566947,121.030520|14.566947,121.030520|14.566947,121.030520|14.567590,121.031181|14.567377,121.031236|14.567447,121.031204|14.567377,121.031236|14.567377,121.031236|14.567377,121.031236|14.567377,121.031236|14.567377,121.031236|14.567377,121.031236|14.567590,121.031181|14.567377,121.031236|14.567590,121.031181|14.567377,121.031236|14.567447,121.031204|14.567377,121.031236|14.567447,121.031204|14.567377,121.031236|14.567466,121.030726|14.567377,121.031236|14.567377,121.031236|14.567377,121.031236|14.567447,121.031204|14.567377,121.031236|14.567056,121.030569|14.567012,121.030539|14.567049,121.030568|14.567009,121.030545|14.567468,121.030728|14.567031,121.030549|14.567007,121.030545|14.567098,121.030403|14.567037,121.030548|14.567178,121.030624|14.566899,121.030486|14.566946,121.030520|14.567056,121.030569|14.567056,121.030569|14.567056,121.030569|14.566946,121.030520|14.566947,121.030522|14.566947,121.030522|14.566947,121.030522|14.567103,121.030594|14.566946,121.030520|14.566947,121.030522|14.566947,121.030524|14.567028,121.030556|14.566780,121.030502|14.566780,121.030502|14.567103,121.030594|14.567103,121.030594|14.566947,121.030522|14.566946,121.030520|14.566946,121.030520|14.566946,121.030520|14.566947,121.030524|14.566947,121.030524'; 

    $data=GetSnailTrail($path); 

    if($data) { 

     $json=json_decode($data,true); 
     $points=$json['snappedPoints']; 

     foreach($points as $key => $value){ 
      $obj=(object)$value; 
      $lat=$obj->location['latitude']; 
      $lng=$obj->location['longitude']; 
      $index=property_exists($obj,'originalIndex') ? $obj->originalIndex : 'n/a'; 
      $id=$obj->placeId; 
      echo 'id:'.$id.' index:'.$index.' lat:'.$lat.' lng:'.$lng.'<br />'; 
     } 
    }

你可以进一步简化代码最初构建路径时。而不是如果你要构建的阵列，并在while循环像这样与纬度/经度填充的复杂函数来处理$jsonarr数据：

$pathdata=array(); 

while($row = mssql_fetch_array($query)){ 
    $jsonarr[] = array(
     'id'  => $row['ID'], 
     'account' => $row['ACCOUNT'], 
     'datetime' => date("m/d/Y H:i:s", strtotime($row['DATETIME'])), 
     'loc'  => $row['LOCATION'], 
     'longi'  => $row['LONG'], 
     'lat'  => $row['LAT'], 
     'lac'  => $row['LAC'], 
     'cid'  => $row['CID'], 
     'remarks' => $row['REMARKS'] 
    ); 
    $pathdata[]="{$row['LAT']},{$row['LONG']}"; 
} 

$path=implode('|',$pathdata);

然后，可以implode使用所选择的定界符的数据（|）实现一连串的要点。

使用JavaScript，你可以发挥一下有以下处理此：

echo " 
<script type='text/javascript'> 
    /* \$data is already a json object, echo it in javascript and process */ 
    var path={$data}; 

    function processpath(path){ 
     var json=path.snappedPoints; 
     for(var o in json){ 
      try{ 
       var point=json[ o ]; 
       if(typeof(point)!='undefined'){ 

        var lat=point.hasOwnProperty('location') && point.location.hasOwnProperty('latitude') ? point.location.latitude : false; 
        var lng=point.hasOwnProperty('location') && point.location.hasOwnProperty('longitude') ? point.location.longitude : false; 
        var index=point.hasOwnProperty('originalIndex') ? point.originalIndex : 'n/a'; 
        var id=point.hasOwnProperty('placeId') ? point.placeId : 'n/a'; 

        if(lat && lng) console.log('id:%s, index:%s, lat:%s, lng:%s', id, index, lat, lng); 
       } 
      }catch(err){ 
       console.warn(err); 
       continue; 
      } 
     } 
    } 
    processpath(path); 
</script>";

谢谢你的回答。请问如何摆脱'BR'？ –

哦，对不起 - BR'是一个本地定义的常量 - 我总是忘记删除，当发布的答案...这是'
' – RamRaider

谢谢...但我怎么能把它放在$ jsonarray这将是得到我的JavaScript显示？而不是从数据库的长经度？ –
