The async.retry function runs once-CodePudding

I can't find a proper explanation of how to use the retry function from the async librarydocs

var async = require('async');
    
function callFunc(data, time, name, callback) {
     console.log("#")
     callback({message: data, time, name}, null); //error
     // callback(null, {message: "ok"});               // ok
}


var func = callFunc.bind(null, "data", "time", "name", function (err, data) {
     console.log(data);
     return err;
})
async.retry({times: 3, interval: 1000}, func, function (err, results) {
     console.log('===================================');
     console.log('Async function');
})

Example of what I implement(but simpler). Can you tell me what I'm doing wrong? Killed the whole day for this.

P.S. The function should be called three times on error.

CodePudding user response：

The async.retry function expects a function that has the signature function (callback, results), where callback is a callback function that you should call when the operation is complete, and results is an object that contains the results of the operation so far.

CodePudding user response：

var async = require('async');

function callFunc(data, time,callback) {
     console.log(data, time)
     callback({message: "err"}, null); // error
     // callback(null, {message: "ok"}); // ok
}

async.retry({times: 3, interval: 1000}, function(callback, results) {
     callFunc("test", "data", callback)
},
function (err, results) {
     console.log('===================================');
     console.log('Async function');
})
