我正在尝试使用php-mongo库构建一个在mongo中搜索地理空间数据的查询。
对象结构
{
"_id" : ObjectId("536ecef59bdc8977f1e9c06f"),
"location" : {
"type" : "Point",
"coordinates" : [
[
-74.220408,
40.727703
]
]
},
"bounds" : {
"type" : "Polygon",
"coordinates" : [
[
[
-74.221403,
40.728457
],
[
-74.219413,
40.728457
],
[
-74.219413,
40.726949
],
[
-74.221403,
40.726949
],
[
-74.221403,
40.728457
]
]
]
},
"tile" : {
"type" : "Polygon",
"coordinates" : [
[
[
-74.220498,
40.727772
],
[
-74.220318,
40.727772
],
[
-74.220318,
40.727634
],
[
-74.220498,
40.727634
],
[
-74.220498,
40.727772
]
]
]
},
"status" : "2",
"dev" : "0"
}
索引
[
{
"v" : 1,
"key" : {
"_id" : 1
},
"name" : "_id_",
"ns" : "atlantic.Analyzer_Marks"
},
{
"v" : 1,
"key" : {
"location.coordinates" : "2d"
},
"name" : "location.coordinates_2d",
"ns" : "atlantic.Analyzer_Marks"
},
{
"v" : 1,
"key" : {
"bounds" : "2dsphere"
},
"name" : "bounds_2dsphere",
"ns" : "atlantic.Analyzer_Marks",
"2dsphereIndexVersion" : 2
},
{
"v" : 1,
"key" : {
"tile" : "2dsphere"
},
"name" : "tile_2dsphere",
"ns" : "atlantic.Analyzer_Marks",
"2dsphereIndexVersion" : 2
}
]
$mongo = new MongoClient("mongodb://someserver.com:27017");
$marks = $mongo->selectDB('atlantic');
$q = array('bounds' => array(
'$geoWithin' => array(
'$geometry' => array(
'type' => 'Polygon',
'coordinates' => array(array(
array(40.125246,-74.327963),
array(40.125246,-74.325989),
array(40.123738,-74.325989),
array(40.123738,-74.327963),
array(40.125246,-74.327963)
))
)
)
)
);
$marks = new MongoCollection($marks,'Analyzer_Marks');
$marks = $marks->find($q);
//var_dump($marks);
$results = array();
if(!empty($marks)){
foreach($marks as $mark) {
$results[] = array(
"location" => $mark['location'],
"tile" => $mark['tile'],
"status" => $mark['status']
);
}
}
这是我得到的错误:
致命错误:未捕获的异常' MongoCursorException'同 message' someserver.com:27017:无法规范查询:BadValue不好 地理查询'在/var/www/html/one-call/lib/somefile.php:97
MongoDB版本2.6.1
答案 0 :(得分:0)
我可以重现那个错误。我认为你缺少一个围绕坐标数组的数组调用:
$mongo = new MongoClient("mongodb://someserver.com:27017");
$marks = $mongo->selectDB('atlantic');
$q = array('bounds' => array(
'$geoWithin' => array(
'$geometry' => array(
'type' => 'Polygon',
'coordinates' => array(
array(
array(40.125246,-74.327963),
array(40.125246,-74.325989),
array(40.123738,-74.325989),
array(40.123738,-74.327963),
array(40.125246,-74.327963)
)
)
)
)
)
);
修改代码后,我不再收到该错误
