安排 API 调用以将结果保存到数据库

Question

I currently have a MERN stack web application hosted on Zeit, which is a simple stock simulator. I would like to schedule an API call to an endpoint every weekday at 4:00pm to pull some market data for the day, and save it to a MongoDB database. What is the best way to do this? For reference I am familiar with Microsoft Azure, and AWS. Thanks

Answer 1

In AWS, you can use a CloudWatch events rule that triggers a lambda function every weekday at 4:00pm. Lambda function should have code to read the data and save data in MongoDB.

Answer 2

You can use Azure Functions with time trigger for it:

function.json

{
    "schedule": "0 0 4 * * *",
    "name": "myTimer",
    "type": "timerTrigger",
    "direction": "in"
}

JavaScript code:

module.exports = function (context, myTimer) {
    var timeStamp = new Date().toISOString();

    if (myTimer.IsPastDue)
    {
        context.log('Node is running late!');
    }
    context.log('Node timer trigger function ran!', timeStamp);   
    //LOGIC TO PERFORM REQUEST / INSERT  on Mongo

    context.done();
};
