1. It is written
on the official website.axios.post(url, data)
.then(response => {
console.log(response);
})
.catch(error => {
console.log(error);
})2. The company project is written as
axios.post(url, data)
.then(response => {
console.log(response);
}, error => {
console.log(error);
})I am a rookie. I haven"t used then and catch before. Are these two writing methods the same? Thank you
first of all, this is not about axios catch but about the then of new Promise ()
Ruan Yifeng wrote very clearly in the promise document
then Reject thencatch
// bad
promise
.then(function(data) {
// success
}, function(err) {
// error
});
// good
promise
.then(function(data) { //cb
// success
})
.catch(function(err) {
// error
});
thentry/catchcatchthenthere is no saying that who is good or bad mainly depends on the business. It may be easy to understand some
in this way.
catch
console.log(response);
the above code reports an error and cannot be captured.
