响应对象未分配给变量REDUX-SAGA

Question

后端的响应出现问题。

我使用猫鼬删除了一个具有特定id的项目。

create方法运行良好，我可以获得值响应并将其分配到一个变量中。

Delete也很好，但我无法获得响应值来将响应分配给变量const post

function* deletePostSaga(action) {
try {
console.log("_id: ", action.payload);
const post = yield call(api.deletePost, action.payload);
console.log("Post - Delete: ", post);
yield put(actions.deletePost.deletePostSuccess(post));
} catch (err) {
console.error(err);
yield put(actions.deletePost.deletePostFailure(err));
}
}

api.deletePost:

import axios from "axios";
export const fetchPosts = () => axios.get(`/posts`);
export const createPost = (payload) => axios.post(`/posts`, payload);
export const updatePost = (payload) => axios.put("/posts", { data: payload });
export const deletePost = (payload) => {
console.log(payload);
axios.delete(`/posts`, { data: payload });
};

项目被删除，我从devtool检查网络并检查预览，我还得到了响应对象：

message: "Delete successfully"
post: {author: "Anonymous", likeCount: 0, _id: "60d99146df51c152f189b1c4", title: "123", content: "123",…}
attachment: ""
author: "Anonymous"
content: "123"
createdAt: "2021-06-28T09:07:18.178Z"
likeCount: 0
title: "123"
updatedAt: "2021-06-28T09:07:18.178Z"
__v: 0
_id: "60d99146df51c152f189b1c4"
success: true

只是不知道为什么我不能将响应分配给const post变量，它只是显示为undefined。感谢阅读。

Answer 1

deletePost = async (payload) => {
console.log(payload);
const response = await axios.delete(`/posts`, { data: payload });
return response;
};

使用async关键字时，需要使用await才能进行阻塞调用。

Answer 2

您需要更新deletePost才能从axios返回值。你可以这样使用async await：

deletePost = async (payload) => {
console.log(payload);
const response = await axios.delete(`/posts`, { data: payload });
return response
};
