I have this code in AngularJS:
$http({
url: my_url,
method: "GET",
data: null,
headers: {
"Content-Type": "application/json",
"my-token": "mytoken",
}
}).then(function(response, err) {
console.log(response)
console.log(err)
});
When the URL is correct and the status is 200, the response is displayed with status 200. But I want now to test with a wrong Url, then nothing is displayed, neither response nor error, so how to detect if there is no response?
By reading the $http documentation you can handle errors inside your error callback function. Also take a look at this HTTP Status Code list. Any 4xx status code e.g. 404 - not found will end inside the errorCallback function. You are also be able to handle the HTTP status by accessing response.status inside your callback functions.
Please note that there is always a response / HTTP Status code while performing an HTTP-Request.
$http({
method: 'GET',
url: '/someUrl'
}).then(function successCallback(response) {
// this callback will be called asynchronously
// when the response is available
}, function errorCallback(response) {
// called asynchronously if an error occurs
// or server returns response with an error status.
});

$http?then takes two functions as parameters. First is called for success and Second is called for error. This is called promise.
Use following code to catch error:
.then(function(response) {
// Success
}, function(error) {
// Error
})
error in console? What kind of URL you are using?$http({
url: my_url,
method: "GET",
headers: {
"Content-Type": "application/json",
"my-token": "mytoken",
}
}).then(function(response) {
console.log(response)
}, function(error) {
console.log(error);
console.log(error.data);
});
Add a function as second parameter to .then() will track error cases for http calls.
data:nullThe problem was with this line, it should be removed "my-token": "mytoken", Thank you !
errorCallbackofthen()method i.e..then(function (response, err) { }, function(response){ //do stuff} );
