Question

使用AWS java脚本接口将项目插入dynamo db本地表时，发电机数据库获取错误未定义docClient。如何初始化docClient？以下是导致问题的代码。

enter var params = {
TableName: "ADV_Admin",
Item: { "jdate": 45455455411444411,"name": "xyz abc", "pwd": sdewrfsdzs",
  "roles": "[\"ADMIN\",\"USER\"]",  "st": "R",  "uname": "admin"}
};

docClient.put(params, function(err, data) {
if (err)
    console.log(JSON.stringify(err, null, 2));
else
    console.log(JSON.stringify(data, null, 2));
});

在使用docClient之前，您必须在某处定义它，如下所示：

var AWS = require('aws-sdk'); // you probably have this line somewhere already    
var docClient = new AWS.DynamoDB.DocumentClient();

参考错误：未定义docClient
