请求体未定义，嵌套属性的猫鼬验证错误

Question

我正在工作nodejs/express/mongoose

我的模型:

const TodoSchema = new mongoose.Schema({
name: { type: String, required: ['Name is required'] },
},

});

控制器:

async function createTask(req, res) {
try {
const task = new Todo({ name: req.body });
console.log(req);
console.log('Name check: ', req.name);
const result = await task.save();
console.log('check: ', task, result);
// res.send('Task created: ', result);
res.json({ msg: 'Task created', item: result });
} catch (error) {
console.log('Task creation error:', error);
return res.json({
msg: error,
});
}

}

我的回复是:

"msg": {
"errors": {
"name": {
"name": "ValidatorError",
"message": "Name is required",
"properties": {
"message": "Name is required",
"type": "required",
"path": "name"
},
"kind": "required",
"path": "name"
}
},
"_message": "Todo validation failed",
"name": "ValidationError",
"message": "Todo validation failed: name: Name is required"
}

}

对于我的日志，req.name是undefined, req.body.

我看了mongoose验证的文档和type关键字，并尝试了建议，但没有任何帮助。我的post端点怎么了?

Answer 1

当你在你的猫鼬模式中使用required时，你有一个错误，你错过了true参数。下面是我的例子=>

---

const mongoose = require("mongoose");
const TaskSchema = new mongoose.Schema({
name: {
type: String,
required: [true, "You Must Provide name"],
trim: true,
maxlength: [23, "Maximum twenty characters"],
minlength: [5, "Minimum four characters"],
}
});
module.exports = mongoose.model("Task", TaskSchema);

也许，你只是没有添加中间件来表达。

app.use(express.json());
app.use(express.urlencoded({ extended: false }))
