When making two $http calls, the second call should only be executed based on the response from the first call if there is an error present.
When making two $http calls, the second call should only be executed based on the response from the first call if there is an error present.
For optimal handling of your request, it is recommended to utilize the .then() method. By using .then, you have the ability to specify multiple functions that will be executed - the first one in case of success, and the second one in case of an error. Here is an example:
//Initiating the first HTTP call
$http.get('http://your-url.com')
.then(function (response) {
//Success: perform necessary actions here
}, function (response) {
//Error: Retrieve relevant data from the response and proceed with a second HTTP call:
var data = response.data;
var statusCode = response.status;
var statusText = response.statusText;
$http.get('http://your-second-url.com');
});
The response object passed into these functions contains the following properties:
data – The response body
status – The status code of the response (e.g. 404)
headers – Headers included in the response
statusText – Text description of the response status
Here is an example of how you can achieve this:
var getData = $http.get('firstUrl.com');
getData.then(
function(response) {
$scope.movieContent = response.data;
})
.catch(function (error) {
fetchSecondUrl();
console.log("Oops! Something went wrong.");
});
After that :
var fetchSecondUrl = function(){
var fetchData = $http.get('secondUrl.com');
fetchData.then(
// retrieve the data and perform other necessary actions
);
}
