AngularJS $http.delete not working in Azure App Service - angularjs

Question

A follow-up on a similar question I posted yesterday. I am trying to delete data from a table in Azure App service. This is my function in my Angular file.
function delName(user) {
//$scope.categories.push(user);
alert("about to delete. Action cannot be undone. Continue?")
$http.delete('https://test-evangelists-1.azurewebsites.net/tables/people', user, config)
.then(function (res) {
$scope.getNames();
});
}
Then I added an HTML button:
<button id="btn-del-evangelist" class="btn btn-default btn" ng-click="delName(user);">Delete User</button>
This is the value of my headers variable:
var config = {
headers: {
'Access-Control-Allow-Origin':'*',
'ZUMO-API-VERSION': '2.0.0'
}
};
But when I tried to run it, the console returns the following error:
which states that the header for ZUMO-API-VERSION must be specified.
Below is my code for GET and POST
GET:
function getNames() {
$http.get('https://test-evangelists-1.azurewebsites.net/tables/people', config)
.then(function (res) {
console.log(res);
$scope.people = res.data;
});
}
POST
function addName(user){
//$scope.categories.push(user);
alert("about to post!")
$http.post('https://test-evangelists-1.azurewebsites.net/tables/people', user, config)
.then(function (res) {
$scope.getNames();
});
}
Since I have already specified the header in my variable, I wonder what can be wrong here. Any help will be appreciated.
UPDATE:
I figured out that the Id must be appended to the URL before I can perform delete. However, I need to run a GET to retrieve the ID given the parameters but I am still encountering errors when getting the ID.
This is now my Delete function
function delName(user) {
alert("About to delete. Action cannot be undone. Continue?")
var retrievedId = "";
$http.get('https://test-evangelists-1.azurewebsites.net/tables/people', {
params: { name: user.name, location: user.location },
headers: { 'Access-Control-Allow-Origin': '*', 'ZUMO-API-VERSION': '2.0.0' }
})
.then(function (res) {
retrievedId = res.id;
alert(retrievedId);
});
$http.delete('https://test-evangelists-1.azurewebsites.net/tables/people/' + retrievedId, config)
.then(function (res) {
$scope.getNames();
});
}
Does anyone know what is wrong in the GET command when getting the ID?
UPDATE 2: I have written instead an Web Method (asmx) that will connect to SQL server to retrieve the ID passing the needed parameters. The ID will be returned as a string literal but in JSON format. Then I called JSON.parse to parse the string into JSON object then assigned the ID to a variable to which I appended in the URL. –
This is now my Delete function after I have written the Web Method.
function delName(user) {
var confirmres = confirm("You are about to delete this record. Action cannot be undone. Continue?");
var retrievedId = "";
if (confirmres == true) {
//get the ID via web service
$http.get('\\angular\\EvangelistsWebService.asmx/GetId', {
params: { name: user.name, location: user.location },
headers: { 'Access-Control-Allow-Origin': '*', 'ZUMO-API-VERSION': '2.0.0' },
dataType: "json",
contentType: "application/json; charset=utf-8"
})
.then(function (res) {
$scope.retData = res.data;
var obj = JSON.parse($scope.retData);
angular.forEach(obj, function (item) {
if (item.length == 0)
alert('No data found');
else {
//perform delete after getting the ID and append it to url
$http.delete('https://test-evangelists-1.azurewebsites.net/tables/people/' + item.id, config)
.then(function (res) {
$scope.getNames();
});
alert(item.id + ' deleted');
}
});
});
}
}
That is one way that I have learned on how to call HTTP DELETE on AngularJS. But I don't know if that is the optimal one. In any case, that works for me, unless there will be other suggestions.

Answer 1

$http.delete only has one parameter (config), not two (data, config).
Delete API
delete(url, [config]);
vs.
Post API
post(url, data, [config]);
To your updated problem:
To delete an item from your table, it appears the correct url is:
/tables/tablename/:id
Note the : before id.
