我正在向API端点发出POST请求,该端点应该将属性的布尔值更改为“true”。
粗略地说:
export const toggleToTrue = payload => {
return (dispatch, getState) => {
let store = getState();
dispatch({ type: "TOGGLE_TO_TRUE", payload });
return axios
.post(
someendpoint,
{ payload },
{
headers: {
Authorization: "Bearer " + accessToken,
"Content-type": "application/json"
}
}
)
.then(res =>
dispatch({
type: "TOGGLE_TO_TRUE_RESOLVE",
res: res.data
})
)
.catch(err =>
dispatch({
type: "TOGGLE_TO_TRUE_ERROR",
err: err
})
);
};
};
然后在我的减速机上:
case "TOGGLE_TO_TRUE":
newState.status = action.type;
newState.error = null;
return [...state, newState];
break;
case "TOGGLE_TO_TRUE_RESOLVE":
if (action.res.errorCode == 0) {
newState.status = "TOGGLE_TO_TRUE_SUCCESS";
// Need to dispatch again the action to get updated list
} else {
newState.status = "TOGGLE_TO_TRUE_ERROR";
newState.error = getErrorMessage(action.res);
}
return [...state, newState];
break;
case "TOGGLE_TO_TRUE_ERROR":
newState.status = action.type;
newState.error = getErrorMessage(action.err);
return [...state, newState];
break;
目前,我的POST请求是成功的,因为我没有从这个帖子请求中获取数据,我需要做另一个GET请求来获取更新的对象。
我在代码中的哪个位置?
在发送TOGGLE_TO_TRUE_RESOLVE
行动之后:
...
.then(res =>
dispatch({
type: "TOGGLE_TO_TRUE_RESOLVE",
res: res.data
})
)
.then(callTheApiAgain)
.then(res =>
dispatch({
type: "TOGGLE_TO_TRUE_SUCCESS",
res: res.data
})
);
但是你还需要在你的减速机中处理新的动作TOGGLE_TO_TRUE_SUCCESS
。
