Question

你好，我想以JSON格式放置操作。可能是我的JSON解析错误，因此我无法更新Data。我的JSON正文数据是

[{
  "receiptNo": "21456",
  "rollno": 12201,
  "bankcode": 2,
  "userid": "rifat",
  "__v": "0"
}]

还有我的NodeJS代码：

router.put('/receiptmaster1/update/:receiptNo', function (req,res) {
  receipt_master1.updateMany({ 
    receiptNo: req.params.receiptNo 
  }, {
    receiptNo: req.body.receiptNo,
    rollno: req.body.rollno,
    bankcode : req.body.bankcode,
    userid: 'rifat',
    __v: "0"
  }).then(function(err) {
    res.send({
      success: true,
      message: "Updated Successfully Master2"
    });
  }).catch(err => {
    res.status(500).send({
      message: err.message || "Error while Updating Server Data"
    });
  });
});

尽管我收到了此回复，但我的数据没有更新

"success":true,"message":"Updated Successfully Master2"

请帮助。

您的JSON是数组中的单个对象。发送时，请将发布的格式更改为对象（不包含包装数组）：

{
  "receiptNo": "21456",
  "rollno": 12201,
  "bankcode": 2,
  "userid": "rifat",
  "__v": "0"
}

或更改在服务器上的访问方式：

router.put('/receiptmaster1/update/:receiptNo', function (req,res) {
  receipt_master1.updateMany({ 
    receiptNo: req.params.receiptNo 
  }, {
    receiptNo: req.body[0].receiptNo,
    rollno: req.body[0].rollno,
    bankcode : req.body[0].bankcode,
    userid: 'rifat',
    __v: "0"
  }).then(function(err) {
    res.send({
      success: true,
      message: "Updated Successfully Master2"
    });
  }).catch(err => {
    res.status(500).send({
      message: err.message || "Error while Updating Server Data"
    });
  });
});

请注意从req.body.到req.body[0].的变化
