Amazon dynamodb 在DynamoDB中查询索引会导致主键错误

我发现在桌子上查询GSI很困难。下面的代码示例导致与主键相关的键错误，尽管我使用的是索引

表定义：

TableName : config.user_table,
KeySchema: [       
    { AttributeName: "user", KeyType: "HASH"}
],
AttributeDefinitions: [       
    { AttributeName: "user", AttributeType: "S" },
    { AttributeName: "activation_code", AttributeType: "S" },
],
GlobalSecondaryIndexes: [
    {
        IndexName: "activation_code_index",
        KeySchema: [
            {AttributeName: "activation_code", KeyType: "HASH"}
        ],
        Projection: {
            ProjectionType: "ALL"
        },
        ProvisionedThroughput: {
            "ReadCapacityUnits": 1,"WriteCapacityUnits": 1
        }
    }
],
ProvisionedThroughput: {       
    ReadCapacityUnits: 10, 
    WriteCapacityUnits: 10
}

var params = {
    TableName: config.user_table,
    IndexName: "activation_code_index",
    KeyConditionExpression: "activation_code = :code", 
    ExpressionAttributeValues: {
        ":code": code
    }
};
return dcl.query(params).promise();

查询定义：

TableName : config.user_table,
KeySchema: [       
    { AttributeName: "user", KeyType: "HASH"}
],
AttributeDefinitions: [       
    { AttributeName: "user", AttributeType: "S" },
    { AttributeName: "activation_code", AttributeType: "S" },
],
GlobalSecondaryIndexes: [
    {
        IndexName: "activation_code_index",
        KeySchema: [
            {AttributeName: "activation_code", KeyType: "HASH"}
        ],
        Projection: {
            ProjectionType: "ALL"
        },
        ProvisionedThroughput: {
            "ReadCapacityUnits": 1,"WriteCapacityUnits": 1
        }
    }
],
ProvisionedThroughput: {       
    ReadCapacityUnits: 10, 
    WriteCapacityUnits: 10
}

var params = {
    TableName: config.user_table,
    IndexName: "activation_code_index",
    KeyConditionExpression: "activation_code = :code", 
    ExpressionAttributeValues: {
        ":code": code
    }
};
return dcl.query(params).promise();

错误：

message: 'One or more parameter values were invalid: Missing the key user in the item',
code: 'ValidationException',

尝试在代码中的

activation\u code\u index

周围使用双引号。JSON的标准要求双引号，而不是单引号。@JeffreyPhillipsFreeman将单引号改为双引号，但仍然存在相同的问题。唯一让我感到不寻常的是，在表定义中，在二级索引之前没有“CREATE:”标记。你确定索引是真的吗created@JeffreyPhillipsFreeman我可以在dynamodbui中看到索引。我还可以在UI中查询索引，问题似乎是通过aws-sdk进行查询。对不起，我当时不知所措：(
