I am attempting to send a params object to the $http.get() method. My params are structured as follows:
var params = {
one: value,
two: value
}
I am trying to pass them into my function like this:
$http.get('/someUrl', params)
.success(function(data) {
// operations
})
.error(function(data) {
// error handling
});
Is this the correct approach for accomplishing this task?
In the realm of $http, the second parameter is a config object (refer to documentation). This config object, amidst other properties, recognizes a params property:
{Object.<string|Object>} – Assortment of strings or objects that will be serialized with the paramSerializer and attached as GET parameters.Thus, you must provide the parameters in this manner:
var config = {
params: {
one: value,
two: value
}
}
$http.get('/someUrl', config).then(...)
Assuming the values for the parameters are '1' and '2' respectively, $http will dispatch a GET request to the subsequent URL:
/someUrl?one=1&two=2
On a side note, it's advised to refrain from utilizing the success and error functions on $http. They have been deprecated since angular 1.4.4. Instead, use the methods then with a success and an error callback, or just a success callback followed by catch.
To make actual calls, it is recommended to utilize a factory or service that can be injected into the necessary controllers. Below is an example of a factory with parameters being passed:
.factory('Chats', function ($http, $rootScope, $stateParams) {
return {
all: function () {
return $http.get('http://ip_address_or_url:3000/chats', { params: { user_id: $rootScope.session } })
}
};
});
Within your controller, you can incorporate the service in this manner:
.controller('ChatsCtrl', function ($scope, Chats) {
Chats.all().success(function (response) {
$scope.chats = response;
})
})
Recently, I encountered a similar issue and found a solution by adding extra details to my request. I utilized the accepted answer but included some additional headers:
$http.get(url, {
params: {
paramOne: valueOne,
paramTwo: valueTwo,
...
},
headers: {
'key': 'value'
},
// In my case, setting the responseType was necessary as I was downloading a PDF document from this REST endpoint
// This may not be needed in your scenario,
// but including it here for future reference
responseType: 'arraybuffer'
}).success(
function(data, status, headers, config) {
// Perform operations on the data received
}).error(function(data) {
// Handle errors related to data retrieval
});
According to the $http documentation, it is recommended to include an object as the second argument when using the $http.get method. This object can contain additional parameters.
Here's an example of how you can use this:
$http.get('/anotherUrl', {params: additionalParams})
.success(function(result) {
// do something
})
.error(function(result) {
// handle error
});
