当在 useEffect 函数中调用 action 时,react-component 会无休止地重新渲染
useEffect(() => {
props.getApi('pages/websitepage/page_type/choices')
},[])
在这里,我使用 connect 方法来调度动作(也尝试了 hooks 方式)。
export function getApi(url) {
return dispatch => {
Axios
.get(
BASE_URL + url ,{
headers: header
}
)
.then(response => {
dispatch(fetchResponse(response.data.data));
})
.catch(error => {
console.log(error)
});
};
}
export const fetchResponse = (data) => {
console.log('data',data);
return{
type: 'FETCH_RESPONSE',
payload: data
}
};
正如你在这里看到的,我正在调用动作调度来存储状态。但是组件不断重新渲染,我有什么可能的解决方案来阻止这种行为吗?在下面附加记录器响应
action FETCH_RESPONSE
prev state {isAuthenticated: true, error: null, isLoading: false, currentBlogPage: 0, submitting: false, …}
action {type: "FETCH_RESPONSE", payload: Array(4)}
next state {isAuthenticated: true, error: null, isLoading: false, currentBlogPage: 0, submitting: false, …}
action FETCH_RESPONSE
prev state {isAuthenticated: true, error: null, isLoading: false, currentBlogPage: 0, submitting: false, …}
action {type: "FETCH_RESPONSE", payload: Array(4)}
next state {isAuthenticated: true, error: null, isLoading: false, currentBlogPage: 0, submitting: false, …}
action FETCH_RESPONSE
prev state {isAuthenticated: true, error: null, isLoading: false, currentBlogPage: 0, submitting: false, …}
action {type: "FETCH_RESPONSE", payload: Array(4)}
next state {isAuthenticated: true, error: null, isLoading: false, currentBlogPage: 0, submitting: false, …}
