查询dynamoDB以获取X和Y之间的值

const AWS = require('aws-sdk');

AWS.config.update({ region: 'your_region' }); // 设置AWS区域

const dynamodb = new AWS.DynamoDB.DocumentClient();

const tableName = 'your_table_name'; // 替换为实际的表名
const xValue = 'your_x_value'; // 替换为实际的X值
const yValue = 'your_y_value'; // 替换为实际的Y值

const params = {
  TableName: tableName,
  KeyConditionExpression: '#x = :xValue AND #y BETWEEN :startY AND :endY',
  ExpressionAttributeNames: {
    '#x': 'X',
    '#y': 'Y',
  },
  ExpressionAttributeValues: {
    ':xValue': xValue,
    ':startY': yValue,
    ':endY': yValue,
  },
};

dynamodb.query(params, (err, data) => {
  if (err) {
    console.error('Error querying DynamoDB:', err);
  } else {
    console.log('Query result:', data.Items);
  }
});
