从数组react redux thunk调度异步操作

Question

根据需要，我们需要从数组列表中进行API调用。使用了redux thunk进行异步操作。在api调用完成后将请求参数传递给reducer时出现问题。

# From the container
let document = [ bankstatement1,bankstatement2];
document.map(element => {
dispatch ( actions.uploadFiles(element) )
});
# inside actions
export const uploadFiles = (payload) => {
return async dispatch => {

const response = await callAPIMiddleware(dispatch, {
types: ['DOC_UPLOAD_START','DOC_UPLOAD_SUCCESS','DOC_UPLOAD_ERROR'],
endPoint: ApiEndpoints.DOCUMENT_UPLOAD,
type: HTTP_METHOD_TYPE.POST,
payload: payload,
headers: Headers.multipart,

});
return response;
};
};
# inside axios middle ware
export const callAPIMiddleware = async (dispatch, RequestParams) => {
# calling upload_start ,here also the request payload being asked.     
dispatch({
type: "DOC_UPLOAD_START,
data:RequestParams //bankstatement1,bankstatement2
});

# let res = await axios.post(endPoint,RequestParams, {
headers: reqHeaders,
config: reqConfig,
});
if (res && res.data) {

dispatch({
type:'DOC_UPLOAD_SUCCESS',
data: res.data,
param:RequestParams //bankstatement2,bankstatement2 here it is always referring to "bankstatement2" 
});

}

After the API call is finished, reference to first request parameter is overridden by second one.Can anyone suggest how we can still refer to the first element .

编辑：如果你试图把最后一段逻辑放在"；那么"；所以它肯定在那里范围内？

axios.post(endPoint,RequestParams, {
headers: reqHeaders,
config: reqConfig,
}).then(res => {
console.log('calling dispatch for ', RequestParams);
if (res && res.data) {
dispatch({
type:'DOC_UPLOAD_SUCCESS',
data: res.data,
param: RequestParams,
});
} else {
console.log('oops no result for ', RequestParams);
}
})
