示例1: dispatch
return async dispatch => {
if (!sourceDataSource) {
// explore not initialized
dispatch(queriesImportedAction({ exploreId, queries }));
return;
}
let importedQueries = queries;
// Check if queries can be imported from previously selected datasource
if (sourceDataSource.meta.id === targetDataSource.meta.id) {
// Keep same queries if same type of datasource
importedQueries = [...queries];
} else if (targetDataSource.importQueries) {
// Datasource-specific importers
importedQueries = await targetDataSource.importQueries(queries, sourceDataSource.meta);
} else {
// Default is blank queries
importedQueries = ensureQueries();
}
const nextQueries = importedQueries.map((q, i) => ({
...q,
...generateEmptyQuery(queries),
}));
dispatch(queriesImportedAction({ exploreId, queries: nextQueries }));
};示例2: async
return async (dispatch, getState) => {
const datasourceName = instance.name;
// Keep ID to track selection
dispatch(loadDatasourcePendingAction({ exploreId, requestedDatasourceName: datasourceName }));
let datasourceError = null;
try {
const testResult = await instance.testDatasource();
datasourceError = testResult.status === 'success' ? null : testResult.message;
} catch (error) {
datasourceError = (error && error.statusText) || 'Network error';
}
if (datasourceError) {
dispatch(loadDatasourceFailureAction({ exploreId, error: datasourceError }));
return Promise.reject(`${datasourceName} loading failed`);
}
if (datasourceName !== getState().explore[exploreId].requestedDatasourceName) {
// User already changed datasource again, discard results

}
if (instance.init) {

}
if (datasourceName !== getState().explore[exploreId].requestedDatasourceName) {
