无法访问req.body的值

Question

我正在尝试使用Axios在Mongo中执行PUT请求以更新我的DB，这样我就可以更新当前周和季节。在我的路由中，我可以访问req.body，但如果我尝试设置值，它会说这些值是未定义的。在这一点上，我尝试了很多不同的事情。我也遇到了这个问题：；强制转换为数字失败"；。

以下是请求的样子：

function currentWeek() {
const currentWeek =
"https://api.sportsdata.io/v3/nfl/scores/json/CurrentWeek?key=...";
axios.get(currentWeek).then((res) => {
const weekCheck = res.data;
const timeframeURL =
"https://api.sportsdata.io/v3/nfl/scores/json/Timeframes/current?key=...";
console.log(weekCheck);
axios.get(timeframeURL).then((res) => {
const timeframeWeek = res.data;
// console.log(timeframeWeek);
const thisWeek = timeframeWeek.filter(
(timeframeWeek) => timeframeWeek.Week === weekCheck
);
console.log(thisWeek);
const config = {
headers: {
"Content-Type": "application/json",
},
};

axios
.put("http://localhost:4000/api/currentweek/5ffce18e78d4742414cf279e", thisWeek, config)
.then((res) => console.log("working"))
.catch((err) => console.error(err));
console.log("Done!");
});
}); 
}

这是我的路线：

router.put("/:_id", async (req, res) => {
const { Season, Week } = req.body;
const { _id } = req.params;
const weekField = {};
// SETING THE VALUES FROM REQ.BODY TO BE IN weekField
if (Season) weekField.Season = Season;
if (Week) weekField.Week = Week;
try {
let weekParam = await CurrentWeek.find({_id});
if (!weekParam) return res.stats(404).json({ msg: "ID in the Params does not exist" });
console.log(_id);
console.log(req.body) // RETURNS THE OBJECT CORRECTLY
console.log(weekField); // RETURNS AS AN EMPTY OBJECT
console.log("From Route ^^");
weekParam = await CurrentWeek.findOneAndUpdate(
_id,
{ $set: weekField },
{ new: true }
);
res.json(weekParam);
} catch (err) {
console.error(err.message);
res.status(500).send("Server Error");
}
});

这是型号：

const mongoose = require('mongoose');
const CurrentWeekSchema = mongoose.Schema([{
Week: Number,
Season: Number
}]);
const CurrentWeek = module.exports = mongoose.model('currentweek', CurrentWeekSchema); 
//^enables require from routes
module.exports.getCurrentWeek = function(callback, limit){
CurrentWeek.find(callback).limit(limit);
}

这里有一个我试图接受的对象的例子：

[
{
SeasonType: 3,
Season: 2020,
Week: 2,
Name: 'Divisional Playoffs',
ShortName: 'Divisional',
StartDate: '2021-01-12T00:00:00',
EndDate: '2021-01-18T23:59:59',
FirstGameStart: '2021-01-16T16:35:00',
FirstGameEnd: '2021-01-16T20:35:00',
LastGameEnd: '2021-01-17T22:40:00',
HasGames: true,
HasStarted: true,
HasEnded: false,
HasFirstGameStarted: false,
HasFirstGameEnded: false,
HasLastGameEnded: false,
ApiSeason: '2020POST',
ApiWeek: '2'
}
]

Answer 1

我发现了这个问题，也许这对将来的其他人有帮助！

在我的路由器文件中，我需要更改这个：

const { Season, Week } = req.body;
const { _id } = req.params;
const weekField = {};
// SETING THE VALUES FROM REQ.BODY TO BE IN weekField
if (Season) weekField.Season = Season;
if (Week) weekField.Week = Week;

对此：

const data = req.body;
const { Season, Week } = data[0];
const { _id } = req.params;
const weekField = {};
// SETING THE VALUES FROM REQ.BODY TO BE IN weekField
if (Season) weekField.Season = Season;
if (Week) weekField.Week = Week;

原因是put请求接收的数据来自一个数组，所以我不得不将req.body设置为数组中的第一个对象。
