Question

我对邮递员JSON发布要求的语法是：

{
    "id": 3,
    "type": "Colonial",
    "Location": 1.1,
    "Postnumber": 1424,
    "City": "Helsinki",
    "Reservation_time": "1112"
}

These column hold values in postgresDB
id = serial
type = varchar
location = point
postnumber = int
City = varchar
Reservation time = varchar

我无法弄清楚什么是错误的，因为我得到的错误是整数的错误类型。

编辑：添加了端点模型和服务。

型号：

exports.createTila = async (id, type, location, postnumber, city, reservation_time) => {
  try {
    const result = await client.query(
      "INSERT INTO tila (id, type, location, postnumber, city, reservation_time) VALUES$
      [id, type, location, postnumber, city, reservation_time]
    );
    return result.rows;
  } catch (err) {
    throw new Error(err);
  }
};

服务：

exports.createTila = async (request, response) => {
  try {
    const tilaObject = request.body;
    const newTila = await tilaModel.createTila(tilaObject);
    response.status(200).send(newTila);
  } catch (err) {
    response.status(400).send({ message: err.message });
  }
};

Answer 1

检查表字段的值，任何字段值都将为null，这就是它引发此异常的原因。并更改字段

{
    "id": 3,
    "type": "Colonial",
    "latitude": 1.1,
    "longitude " : 1.1
    "postnumber": 1424,
    "city": "Helsinki",
    "reservation time": "1112"
}

这里的纬度和经度是双精度类型

Answer 2

我认为问题出在point类型的位置，您的json应该具有latitude和longitude值，而不是像1.1这样的浮点数

{
   "id":3,
   "type":"Colonial",
   "Location":{
      "latitude":35.55689,
      "longitude":51.54865
   },
   "Postnumber":1424,
   "City":"Helsinki",
   "Reservation time":"1112"
}

我发现了我的错误：

不是像这样在服务中创建对象

exports.createTila = async (request, response) => {
  try {
    const tilaObject = request.body;
    const newTila = await tilaModel.createTila(tilaObject);
    response.status(200).send(newTila);
  } catch (err) {
    response.status(400).send({ message: err.message });
  }
};

我还需要在服务中定义db列的值，如下所示：

exports.createTila = async (request, response) => {
  try {
    const {id, type, location, postnumber, city, reservation_time} = request.body;
    const newTila = await tilaModel.createTila(id, type, location, postnumber, city, reservation_time);
    response.status(200).send(newTila);
  } catch (err) {
    response.status(400).send({ message: err.message });
  }
};

POSTMAN产生错误：错误：整数类型的输入语法无效：尝试发送POST请求时
