I am currently running 2 servers:
Below is my action for logging a user in:
// Redux Action
export function loginUser(creds, role) {
return dispatch => {
// We dispatch requestLogin to kickoff the call to the API
dispatch(requestLogin(creds));
return axios.post(`${ROOT_URL}/login/${role}`, creds).then((response) => {
console.log(response);
if(response.status === 200) {
// If login was successful, set the token in local storage
localStorage.setItem('id_token', response.data);
// Dispatch the success action
dispatch(receiveLogin(response));
return response;
}
}).catch(err => {
// If there was a problem, we want to
// dispatch the error condition
dispatch(loginError(err.data));
return err;
});
};
}
I purposely disconnected my database to catch errors and see what happens. So, this is what I can see in the terminal:
12:49:24 Project-0 Server is listening at port 3000
12:49:24 Project-0 Mongoose disconnected
12:49:24 Project-0 Mongoose connection error: MongoError: connect ECONNREFUSED 192.168.1.116:27017
12:49:34 Project-0 Wed, 13 Apr 2016 07:19:34 GMT express deprecated res.send(status): Use res.sendStatus(status) instead at app/index.js:61:7
12:49:34 Project-0 OPTIONS /login/admin Wed, 13 Apr 2016 07:19:34 GMT ::ffff:192.168.1.134 200 5.894
12:49:35 Project-0 POST /login/admin Wed, 13 Apr 2016 07:19:35 GMT ::ffff:192.168.1.134 - -
Now, when I submit the login form, status goes from pending to cancelled.
How can we catch this status using axios or do we have to write a mechanism for this in express itself?
Axios 0.10.0
Note: I couldn't tag axios as the tag doesn't exist and I can't create a new one.
use axios.isCancel()
.catch(err => {
if(axios.isCancel(err)) {
// do something
}
}
)
You actually catch errors(unsuccessful responses) in catch statement. You can for example log it to console like this:
.catch(err => {
// If there was a problem, we want to
// dispatch the error condition
dispatch(loginError(err.data));
console.log(err);
return err;
});
