Javascript 在worklight的Http适配器中检索Lat和Long

我正在尝试使用http适配器检索lat和long。当我尝试调用该过程时，我将能够检索结果。但我只想检索lat和long，不想检索其他附加信息。我已附上我的代码

function getGmapLatLng(pAddress) {
var input = {
method : 'get',
returnedContentType : 'json',
path : 'maps/api/geocode/json',
parameters : {
'address' : pAddress,
'sensor' : 'false' // hard-coded
}
}; 
return WL.Server.invokeHttp(input);
var type = typeof input; 
if ("object" == type) {
if (true == response) {

// Drill down into the response object.
var results = response;
var result = results[0];
var geometry = result;
var location = geometry;
} 
else {

return null;
}
} 
else {
return null;
}

}

谁能纠正我哪里做错了

这应该是你的适配器： googleMap.xml：

<?xml version="1.0" encoding="UTF-8"?>
<wl:adapter name="googleMap"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:wl="http://www.worklight.com/integration"
    xmlns:http="http://www.worklight.com/integration/http">
    <displayName>googleMap</displayName>
    <description>googleMap</description>
    <connectivity>
        <connectionPolicy xsi:type="http:HTTPConnectionPolicyType">
            <protocol>http</protocol>
            <domain>maps.googleapis.com</domain>
            <port>80</port>
        </connectionPolicy>
        <loadConstraints maxConcurrentConnectionsPerNode="2" />
    </connectivity>
    <procedure name="getLangLat"/>
</wl:adapter>
