I am new to React Redux, and All I already did:
1) activate my backend server (localhost:5000)
2) activate my front-end server using npm start (localhost:8080)
3) I tried to dispatch action by using
this.props.dispatch({type: ActionTypes.FILE_UPLOAD_REQUEST, email: this.state.email, file: this.state.policyFile});
4) Using atlas-saga, and call my service function associated with the dispatch :
let result = yield call(Atlas.uploadFile, action.email, action.file);
5) define the function as :
export const uploadFile = (email, file) => {
return fetch(`${BASE_URL}/v1/files/${email}/policies`, {
method: 'POST',
headers:{} ,
body: {'file': file}
})
.then(response => response.json())
}
After I try to run a function at my react( a function that calls the dispatch), it gives me errors that they cannot found the route. This is the error message from the console.
Fetch API cannot load https://api-staging.autoarmour.co/v1/files/[email protected]/policies. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access. The response had HTTP status code 500. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
Yes, I did not create any reducer, just pure function that will upload a file. Thank you
