I have an AngularJS service called sensorReadingsAPI
, which has the following function with get
:
var _countSensorReadingsFilter = function () {
return $http.get(config.baseUrl + "/sensorReading/countFilter").then(function (data,status) {
sensorReadingCountFilter = data.data;
return Number(sensorReadingCountFilter);
}).catch(function() {});
};
The /countFilter
is defined in a NodeJS controller:
module.exports = {
countFilter: function (req, res) {
return res.sensorReadingCountFilter();
}
};
And sensorReadingCountFilter
is as follows:
module.exports = function sensorReadingCountFilter(statusCode){
var req = this.req;
var res = this.res;
SensorReading.count({deviceNum:'MBA002'}).exec(function countCB(error, found) {
return res.view({val: found});
});
};
Right now, the count is static (where is written {deviceNum:'MBA002'}
). I need a way to make this value be dinamic, using a variable, preferably being send from the AngularJS controller. I have several devices, with the portential to add even more, and don't want to create a /countFilter
module for each of them.
In other words, a way to send variables from an AngularJS service to a NodeJS controller. When searching for ways to do this, I have found next to nothing.
For clearance: all of this returns the number of readings from the selected device, and config.baseUrl
is the local machine and port.
You can use url parameters in your $http.get('url-here?param1=1,param2=2')
and then you can access these params in your req
object on the server side req.query.param1
.
You also can specify params in config object of $http:
$http.get('my-url-here', { params: {deviceNum:'MBA002'} })
.success()
