'redux-saga'無法異步工作

Question

我正在嘗試（學習）使用redux-saga發出異步發布請求，但是我正在獲得同步行為。

這是我正在使用的代碼：

import {AUTH_REQUEST} from '../constants/authentication';
import {authSuccess, authError} from '../actions/login';
import {takeEvery, call, put, fork, all} from 'redux-saga/effects';
import axios from 'axios';

const authenticate = (username, password) => {
    axios
        .post('http://localhost:8000/api/auth/login/', {username, password})
        .then((response) => {
            console.log('RESPONSE: ', response.data);
            return response.data;
        })
        .catch((error) => {
            throw error;
        });
};

function* watchAuthRequest({username, password, resolve, reject}) {
    try {
        const result = yield call(authenticate, username, password);
        console.log('RESULT', result);
        yield put(authSuccess(result));
        yield call(resolve);
    } catch (error) {
        yield put(authError(error));
        yield call(reject, {serverError: 'Something bad happend !'});
    }
}

const authSaga = function* authSaga() {
    yield takeEvery(AUTH_REQUEST, watchAuthRequest);
};

export default function* rootSaga() {
    yield all([
        fork(authSaga),
    ]);
};

當我提交表單時（我正在使用redux-form），這就是為什么我進入控制台日志的原因：

RESULT: undefined
RESPONSE:  Object {user: Object, token: "04a06266803c826ac3af3ffb65e0762ce909b07b2373c83b5a25f24611675e00"}

甚至authSuccess動作都被分配了一個空的有效負載（ result ）

我在這里做錯什么了嗎？

您缺少return ：

const authenticate = (username, password) => {
    return axios
        .post('http://localhost:8000/api/auth/login/', {username, password})
        .then((response) => {
            console.log('RESPONSE: ', response.data);
            return response.data;
        })
        .catch((error) => {
            throw error;
        });
};
