}

我“米试图上传我的数据文件看起来像这样：

[ 
    { 
    "lastname": "abc", 
    "firstname": "dfx", 
    "employeeid": 78, 
    "hrs": [ 
     { 
     "availhrs": "123", 
     "ttlhrs": "111", 
     "bllhrs": "98", 
     "rto": "16", 
     "ondeckhrs": "0", 
     "nonbllhrs": "0", 
     "employeeid": 78, 
     "dtmonth": "2016-01-01T00:00:00.000Z", 
     "clientid": 1, 
     "clientId": 1, 
     "employeeId": 78 
     } 
    ] 
    } 
]

我创造了我的表是这样的：

var params = { 
    TableName : "ach3", 
    KeySchema: [  
     { AttributeName: "employeeid", KeyType: "HASH" }, //Sort key 
     { AttributeName: "lastname", KeyType: "RANGE" } 
    ], 
    AttributeDefinitions: [  
     { AttributeName: "lastname", AttributeType: "S" }, 
     { AttributeName: "employeeid", AttributeType: "N" } 
    ], 
    ProvisionedThroughput: {  
     ReadCapacityUnits: 10, 
     WriteCapacityUnits: 10 
    } 
};

和这是我如何上传表格：

var allACH = JSON.parse(fs.readFileSync('ach.json', 'utf8')); 


allACH.forEach(function(movie) { 
    var params = { 
     TableName: "ach3", 
     Item: { 
      "lastname": movie.lastname, 
      "firstname": movie.firstname, 
      "employeeid": movie.employeeid, 
      "hrs": movie.hrs 
     } 
    }; 

    dynamodb.putItem(params, function(err, data) { 
     if (err) { 
      console.error("Unable to add item", movie.employeeid, ". Error JSON:", JSON.stringify(err, null, 2)); 
     } else { 
      console.log("PutItem succeeded:", movie.employeeid); 
     } 
    }); 
});

“项目”对象需要具有每个属性的类型信息：所以，你需要像

Item: { 
     "lastname": {S: movie.lastname}, 
     "firstname": {S: movie.firstname}, 
     "employeeid": {S: movie.employeeid}, 
     "hrs": {N: String(movie.hrs) } 
    }

这是告诉说：“姓”是串类型（S）的API。

希望可以帮到

另外，“hrs”本身就是一个json文档，但在你的情况下，你将它声明为一个数字。现在删除“hrs”，看看它是否适用于“lastname”，“firstname”和“employeeid” – hatim
