This code cancel GET requests but cant abort POST calls.
If i send GET requests first and i dont cancel them via abortAll method,they just finish by themselves this token cancel by itself and doesnt work on next requests?
What am i missing?
Thanks,John
import axios from 'axios'
class RequestHandler {
constructor(){
this.cancelToken = axios.CancelToken;
this.source = this.cancelToken.source();
}
get(url,callback){
axios.get(url,{
cancelToken:this.source.token,
}).then(function(response){
callback(response.data);
}).catch(function(err){
console.log(err);
})
}
post(url,callbackOnSuccess,callbackOnFail){
axios.post(url,{
cancelToken:this.source.token,
}).then(function(response){
callbackOnSuccess(response.data);
}).catch(function(err){
callbackOnFail()
})
}
abortAll(){
this.source.cancel();
// regenerate cancelToken
this.source = this.cancelToken.source();
}
}
I have found out that you can cancel post request this way,i missunderstand this documentation part. In previous code,i have passed cancelToken to the POST data request not as a axios setting.
import axios from 'axios'
var CancelToken = axios.CancelToken;
var cancel;
axios({
method: 'post',
url: '/test',
data: {
firstName: 'Fred',
lastName: 'Flintstone'
},
cancelToken: new CancelToken(function executor(c) {
// An executor function receives a cancel function as a parameter
cancel = c;
})
}).then(()=>console.log('success')).catch(function(err){
if(axios.isCancel(err)){
console.log('im canceled');
}
else{
console.log('im server response error');
}
});
// this cancel the request
cancel()
Maybe I'm wrong, but each request should have a unique source object.
Cancel previous Axios request on new request with cancelToken and source.
https://github.com/axios/axios#cancellation
// cancelToken and source declaration
const CancelToken = axios.CancelToken;
let source = CancelToken.source();
source && source.cancel('Operation canceled due to new request.');
// save the new request for cancellation
source = axios.CancelToken.source();
axios.post(url, postData, {
cancelToken: source.token
})
.then((response)=>{
return response && response.data.payload);
})
.catch((error)=>{
return error;
});
