将 axios 的 Get 请求的结果放入数组
我不明白一个非常简单的任务,我用 React 中的 axios 从 API 发出了请求。 如果我通过控制台记录 res.data,就像控制台上单个对象的 170 个结果一样。
我需要将所有这些结果转换为单个对象数组。
这是一项基本任务,但我不明白如何去做。
该应用程序是 Trello 克隆。
我有一个名为 board 的变量,它包含所有数据,通过此列表请求,我抓取 trello 的所有列并附加到 newBoardData 中的 ListObjects [] (它是 board 的克隆)
这是我的代码:
//Get Request
const getList = async (id) => {
try {
return await axios.get(`${ENDPOINT}/lists/${id}`);
} catch (err) {
console.log(err);
}
};
const [loading, setLoading] = useState(false);
// Use Effect for grab the data with the listId
useEffect(() => {
(async () => {
setLoading(true);
const res = await (getList(listId));
//Loading up the listObjects
const oldList = board.board.listObjects
const newList = []
const payload = res.data;
//Adding all the old values to the new list (except for the current payload id)
for(let obj of oldList){
if(obj._id !== payload._id) newList.push(obj)
}
//Adding the current payload id
newList.push(payload)
const data = {
...board,
board: {...board.board, listObjects: newList}
};
setList(res.data);
// Here I put the data objects with the new ListObjects Array
setBoardNew(data);
setLoading(false);
})();
}, []);
这是控制台日志获取请求的res.data:
这里是board对象:
可以看到ListObjects中当前res.data存在垃圾结果
我认为它对每个列表中的每张卡都提出了请求。
非常感谢!
更新:
我将解释该应用程序的工作原理:
我有一个名为 Board.js 的文件,我在其中进行此调用(在控制台日志中,如果我有两列,我有两个调用):
try {
return await axios.get(`${ENDPOINT}/boards/${id}`);
} catch (err) {
console.log(err);
}
};
useEffect(() => {
(async () => {
setLoading(true);
const res = await (getUserBoard(match.params.id));
if (res) {
axios.defaults.headers.common['boardId'] = match.params.id;
} else {
delete axios.defaults.headers.common['boardId'];
}
const payload = { ...res.data, listObjects: [], cardObjects: [] };
const data = {
...state,
board: { ...state.board, ...payload },
};
setBoardData(data);
setLoading(false);
})();
}, []);
然后我将道具数据发送到文件 List .js
{board.board.lists.map((listId, index) => (
<List key={listId} listId={listId} index={index} board={board} />
列表文件发送数据到 card.js
{list.cards.map((cardId, index) => (
<Card key={cardId} cardId={cardId} list={list} index={index} board={boardNew} />
逻辑是:有板(board.js),板上有列表(列)(list.js),列表中有卡片(card.js)
我希望它更清楚。
I don't understand a very simple task, I made a request from a API with axios in react.
If I console log the res.data, is like 170 result of single objects on my console.
I need to convert all these result in a single array of objects.
It's a basic task but I don't understand how to do it.
The application is a Trello Clone.
I have a variable called board that has all the data and with this list request, I grab all the column the the trello and append to ListObjects [] in newBoardData (it's a clone of board)
Here is my code:
//Get Request
const getList = async (id) => {
try {
return await axios.get(`${ENDPOINT}/lists/${id}`);
} catch (err) {
console.log(err);
}
};
const [loading, setLoading] = useState(false);
// Use Effect for grab the data with the listId
useEffect(() => {
(async () => {
setLoading(true);
const res = await (getList(listId));
//Loading up the listObjects
const oldList = board.board.listObjects
const newList = []
const payload = res.data;
//Adding all the old values to the new list (except for the current payload id)
for(let obj of oldList){
if(obj._id !== payload._id) newList.push(obj)
}
//Adding the current payload id
newList.push(payload)
const data = {
...board,
board: {...board.board, listObjects: newList}
};
setList(res.data);
// Here I put the data objects with the new ListObjects Array
setBoardNew(data);
setLoading(false);
})();
}, []);
Here is the console log of the get request res.data:
here is the board object:
You can saw that there is a spam of result with the current res.data in ListObjects
I'think it make a request for every card in every list.
thank you very much!
UPDATE:
I will explain how the app works:
I have a file called Board.js, where I make this call (in the console log I have two call if I have two columns):
try {
return await axios.get(`${ENDPOINT}/boards/${id}`);
} catch (err) {
console.log(err);
}
};
useEffect(() => {
(async () => {
setLoading(true);
const res = await (getUserBoard(match.params.id));
if (res) {
axios.defaults.headers.common['boardId'] = match.params.id;
} else {
delete axios.defaults.headers.common['boardId'];
}
const payload = { ...res.data, listObjects: [], cardObjects: [] };
const data = {
...state,
board: { ...state.board, ...payload },
};
setBoardData(data);
setLoading(false);
})();
}, []);
Then I send the props data to the file List.js
{board.board.lists.map((listId, index) => (
<List key={listId} listId={listId} index={index} board={board} />
The list file send the data to
card.js
{list.cards.map((cardId, index) => (
<Card key={cardId} cardId={cardId} list={list} index={index} board={boardNew} />
The logic is: There is the board(board.js), in the board there are the lists (column)(list.js) in the lists there are the cards (card.js)
I hope it's more clear.

简单地使用这种方法将新的 id 值添加到数组状态中。
simple use this approach to add your new id value into the array state.
