I need to incorporate a retry mechanism in my JavaScript code for calling an API:
$.ajax({
url: api_url + 'report',
type: 'GET',
dataType: 'json',
async: false,
tryCount : 0,
retryLimit : 3,
headers: {
"Authorization": "Basic " + btoa(api_username + ":" + api_pass)
},
data: {start: start_date, end: end_date},
success: function(result) {
data = result.results;
console.log("success");
},
error : function(xhr, textStatus, errorThrown ) {
console.log("in error");
if (textStatus == 'timeout') {
this.tryCount++;
if (this.tryCount <= this.retryLimit) {
//try again
console.log("try count:");
console.log(this.tryCount);
$.ajax(this);
return;
}
return;
}
if (xhr.status == 500) {
console.log("still 500");
} else {
console.log("still !500");
}
}
});
In the event of server issues resulting in an HTTP 500 response, the given JavaScript file may not trigger the "error:" block and the line "console.log("in error");" doesn't appear in the console.
How can I effectively implement a retry logic to automatically reattempt requests multiple times when encountering a 500 status from the server?
