如何在 REST Web 服务中保留 javascript console.log（通过重载）？

Question

I have a Angular 5 application with any javascript console.log("..."); I want create and add a javascript file on top on my application that overloads all console.log("..."); with a POST function to a Web Services.

If my classic application log this:

console.log("start");
console.log("error");
console.log("stop");

I want my Angular5 application to process 3 asynchone POST requests to my Web Services. Example:

POST {"user": "foo", "log": "start"}
POST {"user": "foo", "log": "error"}
POST {"user": "foo", "log": "stop"}

Note: The user in the body is just an example because the final version uses a Json Web Token in the header.

Is there a library to do this because it seems like a basic feature?

How about replacing the default log function.

 (function() { var oldLog = console.log; console.log = function(msg) { oldLog.apply(console, arguments); alert(msg); } })() console.log("test")
