PROSAGA码农传奇-ONOS/AWS Lambda/Kappa-如何在Step函数的GetHistoryExecution中使用nextToken？

<div class =“post-text”itemprop =“text”>
  <P>
    需要在parms中使用nextToken传递给下一次调用getExecutionHistory。您可以递归调用此函数，直到所有令牌都用完为止。通过Cloud watch获取日志时遇到类似情况。

    递归获取历史记录的示例，
  </H2>
  <P>
    将getExecutionHistory包装到promise中并添加到不同的JS文件（比如说writer.js）然后你的主index.js文件可以像这样调用那个函数，
  </p>
   <pre>
    <code>
      // writer.js which writes record to Dynamodb
// returns promise
// when history is fetched , dynamodb will be inserted and it will resolve dataexecution which has nextToken

module.exports.get = function(fwdtoken) {

if (fwdtoken) parms.nextToken= fwdtoken;

return new Promise ( (resolve, reject)=>{
    stepfunctions.getExecutionHistory(params, function(err, dataExecution) {
        if (err){
           reject(err.stack)
        } 
        else {
            const params2 = {
                TableName: table,
                Item: {
                    id: executionARN,
                    execution_history: dataExecution
                }
            };
            dynamoDb.put(params2).promise();
        resolve(dataExecution)
        }
      });   
    })    
};

//This goes in main logic
// Invokes getAllLogs recursilvely

var writer = require('./writer');
var fwdtoken;
