Sequelize 仅以 UTC 格式读取日期时间

Question

我已将 timezone 选项设置为我的时区（Europe/Zagreb 并且我也尝试过 +02:00），并且时间已按原样保存，但是，从数据库中读取时间时，Sequelize 将其转换为 UTC。我也尝试过不同的时区，每个时区都正确保存，但从数据库读取时总是转换为 UTC。

我是不是做错了什么，或者这是一个已知问题，是否有任何解决方法？

我创建了一个新连接：

sequelize = new Sequelize(config.database, config.username, config.password, config);

我的配置如下所示：

"development": {
    "username": "root",
    "password": "root",
    "database": "db",
    "host": "localhost",
    "dialect": "mysql",
    "timezone": "Europe/Zagreb"
}

Answer 1

你可以试试这段代码，我遇到了同样的问题，这对我有用。

const sequelize = new Sequelize(mysql.database, mysql.user, mysql.password, {
    host: mysql.host,
    port:3306,
    dialect:'mysql',
    define: {
      underscored: true,
      freezeTableName: true, //use singular table name
      timestamps: false,  // I do not want timestamp fields by default
    },
    dialectOptions: {
      useUTC: false, //for reading from database
      dateStrings: true,
      typeCast: function (field, next) { // for reading from database
        if (field.type === 'DATETIME') {
          return field.string()
        }
          return next()
        },
    },
    timezone: '+01:00'
});

如果您使用 UTC，可能不需要时区。

例如，我的mysql服务器时区是'+08:00'，

"mysql2": "^1.6.4", "sequelize": "^4.41.2"

const sequelize = new Sequelize(database, username, password, {
    host: hostname,
    port: port,
    dialect: 'mysql',
    dialectOptions: {
        typeCast: function (field, next) {
            if (field.type == 'DATETIME' || field.type == 'TIMESTAMP') {
                return new Date(field.string() + 'Z');
            }
            return next();
        }
    },
    operatorsAliases: false,
    pool: {
        max: 5,
        min: 0,
        acquire: 30000,
        idle: 10000
    }
});

Answer 3

您可以试试这个对我有用的选项：

const sequelize = new Sequelize(database, username, password, {
  host: hostname,
  port: port,
  dialect: 'mysql',
  dialectOptions: {
    encrypt: false,
    options: {
      useUTC: false, // for reading from database
    },
  },
  operatorsAliases: false,
  pool: {
    max: 5,
    min: 0,
    acquire: 30000,
    idle: 10000
  }
});

Sequelize 仅以 UTC 格式读取日期时间

Sequelize reads datetime in UTC only

mysql

timezone

datetime

utc
