使用go sdk扫描dynamodb表并对列表使用包含

package main

import (
    "fmt"
    "github.com/aws/aws-sdk-go/aws"
    "github.com/aws/aws-sdk-go/aws/session"
    "github.com/aws/aws-sdk-go/service/dynamodb"
)

func main() {
    // 创建DynamoDB服务的Client对象
    sess, err := session.NewSession(&aws.Config{
        Region: aws.String("us-west-2"),
    })
    if err != nil {
        panic(err)
    }

    svc := dynamodb.New(sess)

    // 构造ScanInput参数对象
    input := &dynamodb.ScanInput{
        TableName: aws.String("your-table-name"),
    }

    // 执行扫描操作
    result, err := svc.Scan(input)
    if err != nil {
        panic(err)
    }

    // 处理扫描结果
    for _, item := range result.Items {
        // 处理每个条目...
        fmt.Println(item)
    }
}

package main

import (
    "fmt"
    "github.com/aws/aws-sdk-go/aws"
    "github.com/aws/aws-sdk-go/aws/session"
    "github.com/aws/aws-sdk-go/service/dynamodb"
)

func main() {
    // 创建DynamoDB服务的Client对象
    sess, err := session.NewSession(&aws.Config{
        Region: aws.String("us-west-2"),
    })
    if err != nil {
        panic(err)
    }

    svc := dynamodb.New(sess)

    // 构造ScanInput参数对象，同时添加FilterExpression参数来实现包含操作
    input := &dynamodb.ScanInput{
        TableName: aws.String("your-table-name"),
        FilterExpression: aws.String("contains(attribute_name, :value)"),
        ExpressionAttributeValues: map[string]*dynamodb.AttributeValue{
            ":value": {
                S: aws.String("your-value"),
            },
        },
    }

    // 执行扫描操作
    result, err := svc.Scan(input)
    if err != nil {
        panic(err)
    }

    // 处理扫描结果
    for _, item := range result.Items {
        // 处理每个条目...
        fmt.Println(item)
    }
}
