Javascript 使用带有Express的Put方法，我得到了代码200，但没有更新

大家好，我刚刚尝试创建更新函数，并使用Postman更新

firstName

字段。控制台中的结果是HTTP/1.1“200，但未更新任何内容

这是邮递员尸体的结果

{
    "user_id": "5adaa55c0364d01cd9478492",
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiI1YWRhYTU1YzAzNjRkMDFjZDk0Nzg0OTIiLCJpYX4OTJ9.JpDShf4iBFBCQ5rGflKbsj3jisl-PS68UOTnVpxNyXs",
    "data": {
        "userData": [
            {
                "address": [
                    {}
                ]
            }
        ]
    }
}

这就是我试图更新的内容

{
    "data": {
        "userData": [
            {
                "firstName": "George"
            }
        ]
    }
}

这是我从

authentication\u controller.js

exports.update = function (req, res, next) {
  var email = req.body.email;
  var password = req.body.password;
  var role = req.body.role;
  var firstName = req.body.firstName;
  var lastName = req.body.lastName;
  var phone = req.body.phone;
  var number = req.body.number;
  var street = req.body.street;
  var city = req.body.city;
  var postcode = req.body.postcode;
  var user = req.user;

  user.save(function (err) {
    if (err) {
      return next(err)
    } else {
      res.json({
        user_id: user._id,
        token: tokenForUser(user),
        data: {
          email: email,
          password: password,
          userData: [{
            role: role,
            firstName: firstName,
            lastName: lastName,
            phone: phone,
            address: [{
              number: number,
              street: street,
              city: city,
              postcode: postcode
            }],
          }],
        }
      });
    }
  });
}

router.route('/users/:user_id/data')
  .get(requireAuth, AuthenticationController.index)
  .put(requireAuth, AuthenticationController.update);

这是我的

route.js

exports.update = function (req, res, next) {
  var email = req.body.email;
  var password = req.body.password;
  var role = req.body.role;
  var firstName = req.body.firstName;
  var lastName = req.body.lastName;
  var phone = req.body.phone;
  var number = req.body.number;
  var street = req.body.street;
  var city = req.body.city;
  var postcode = req.body.postcode;
  var user = req.user;

  user.save(function (err) {
    if (err) {
      return next(err)
    } else {
      res.json({
        user_id: user._id,
        token: tokenForUser(user),
        data: {
          email: email,
          password: password,
          userData: [{
            role: role,
            firstName: firstName,
            lastName: lastName,
            phone: phone,
            address: [{
              number: number,
              street: street,
              city: city,
              postcode: postcode
            }],
          }],
        }
      });
    }
  });
}

router.route('/users/:user_id/data')
  .get(requireAuth, AuthenticationController.index)
  .put(requireAuth, AuthenticationController.update);

您没有调用mongoose模型。您正在调用用户对象，该对象由

requireAuth

中间件通过解码JWT放置在

req

上

您需要调用/使用实际的mongoose

用户

型号：

const User = require('./path/to/mongoose/model/User')

...

// assuming the decoded JWT user object has an `id` property
User.findByIdAndUpdate(req.user.id, req.body)
    .exec()
    .then(doc => res.json(doc)
    .catch(err => res.json(err))

您是否应该使用update并传递更新的对象

user.update（{data}，{options}，（err，raw）=>{res.send（err？err:raw）}）

@JoeWarner那

{options}在哪里

come from？只是一个占位符，表示可以传递第二个参数中的选项。如果没有，只需传递一个空对象即可any@JoeWarner在这种情况下，什么是

raw

，因为现在的响应是

{“ok”：0，“n”：0，“nModified”：0}

const User=require（“../models/User”）

我正在调用它，我只是没有将此代码粘贴到这里。您不是。您正在从

req调用
user
。user

与

user

不同。这不是在使用它，而是在导入它
