Assume that I have two input boxes with corresponding ng-model as fname and lname. If I call http request as :
$http({method:'GET', url:'/search', params:{fname: fname, lname: lname}})
will it call to the url :
/search?fname=fname&lname=lname
The error I am getting at the backend(python) is :
cannot concatenate str and nontype objects.
Are these parameters not sent as strings? If not, how to get around with this?
Here is how you do it:
$http.get("/url/to/resource/", {params:{"param1": val1, "param2": val2}})
.then(function (response) { /* */ })...
Angular takes care of encoding the parameters.
Maxim Shoustin's answer does not work ({method:'GET', url:'/search', jsonData} is not a valid JavaScript literal) and JeyTheva's answer, although simple, is dangerous as it allows XSS (unsafe values are not escaped when you concatenate them).
Build URL '/search' as string. Like
"/search?fname="+fname"+"&lname="+lname
Actually I didn't use
`$http({method:'GET', url:'/search', params:{fname: fname, lname: lname}})`
but I'm sure "params" should be JSON.stringify like for POST
var jsonData = JSON.stringify(
{
fname: fname,
lname: lname
}
);
After:
$http({
method:'GET',
url:'/search',
params: jsonData
});
We can use input data to pass it as a parameter in the HTML file w use ng-model to bind the value of input field.
<input type="text" placeholder="Enter your Email" ng-model="email" required>
<input type="text" placeholder="Enter your password " ng-model="password" required>
and in the js file w use $scope to access this data:
$scope.email="";
$scope.password="";
Controller function will be something like that:
var app = angular.module('myApp', []);
app.controller('assignController', function($scope, $http) {
$scope.email="";
$scope.password="";
$http({
method: "POST",
url: "http://localhost:3000/users/sign_in",
params: {email: $scope.email, password: $scope.password}
}).then(function mySuccess(response) {
// a string, or an object, carrying the response from the server.
$scope.myRes = response.data;
$scope.statuscode = response.status;
}, function myError(response) {
$scope.myRes = response.statusText;
});
});
Here is a simple mathed to pass values from a route provider
//Route Provider
$routeProvider.when("/page/:val1/:val2/:val3",{controller:pageCTRL, templateUrl: 'pages.html'});
//Controller
$http.get( 'page.php?val1='+$routeParams.val1 +'&val2='+$routeParams.val2 +'&val3='+$routeParams.val3 , { cache: true})
.then(function(res){
//....
})
