I'm trying to pass a params object to the $http.get() service. My params look like this:
var params = {
one: value,
two: value
}
And I'm trying to pass them into my function like so:
$http.get('/someUrl', params)
.success(function(data) {
// stuff
})
.error(function(data) {
// error stuff
});
Is this the correct way to go about doing this?
The second argument of $http is a config object (see documentation). Amongst other properties, the config object accepts a params property:
{Object.<string|Object>} – Map of strings or objects which will be serialized with the paramSerializer and appended as GET parameters. Therefore you have to pass the parameters as such
var config = {
params: {
one: value,
two: value
}
}
$http.get('/someUrl', config).then(...)
Suppose the values for the parameters are respectively '1' and '2', $http will send a GET request to the following url:
/someUrl?one=1&two=2
As a side note, try to avoid using success and error functions on $http. They have been deprecated as of angular 1.4.4. Use the methods then with a success and an error callback instead, or then with only a success callback and catch.
For the actual call use a factory or service that you can inject to the controllers you need it in. This is an example factory passing parameters
.factory('Chats', function ($http, $rootScope, $stateParams) {
return {
all: function () {
return $http.get('http://ip_address_or_url:3000/chats', { params: { user_id: $rootScope.session } })
}
};
});
In your controller you use the service like this
.controller('ChatsCtrl', function ($scope, Chats) {
Chats.all().success(function (response) {
$scope.chats = response;
})
})
I have faced similar issue in recent time and I had to add few additional details to request (I used accepted answer with some headers):
$http.get(url, {
params: {
paramOne: valueOne,
paramTwo: valueTwo,
...
},
headers: {
'key': 'value'
},
// responseType was required in my case as I was basically
// retrieving PDf document using this REST endpoint
// This is not required in your case,
// keeping it for somebody else's reference
responseType: 'arraybuffer'
}).success(
function(data, status, headers, config) {
// do some stuff here with data
}).error(function(data) {
// do some stuff here with data
});
The $http documentation suggest that the second argument to the $http.get method is an object which you can pass with it "param" object.
Try something like this:
$http.get('/someUrl', {params: params})
.success(function(data) {
// stuff
})
.error(function(data) {
// error stuff
});
