api throttling best practices

Introduction to Koa service throttling methods and koa practices I recently met a requirement. It is very simple to start a server. When receiving the request, I call a provided interface and return the result. Because of the performance problem of this interface and the number of requests cannot exceed a specific number, throttling is required in the service.

class, see ratelimiter. For more information about how to use ratelimiter, see ratelimiter usage. The main source code is as follows: Public double acquire () {return acquire (1);} public double acquire (INT permits) {checkpermits (permits); // check whether the parameter is valid (greater than 0) Long microstowait; synchronized (mutex) {// synchronous microstowait = reservenextticket (permits, readsafemicros () to cope with concurrency; // get the time to wait} ticker. sleepmicrosuninterruptib

messages shown above. This restriction also applies to the combination of REST and SOAP API calls. For example, suppose an account makes 1 REST API calls and 1 SOAP API calls at the same time, and one of the clients of that account makes a REST API call. Control Center counts the number of calls per second for that ac

This is a creation in Article, where the information may have evolved or changed. Statement This article is just a summary of my personal reading materials and engineering practices, which may not be the best practice. But hopefully, some help will be given to readers who have doubts about restful API design and engineering practice. Objective The RESTful principle was put forward by Roy Fielding in the fif

So my goal in this article is to start from a practical point of view, give the current Web application of API design best practices (of course, I think the best ~), if it is not appropriate, I will not comply with the standard. Of course, as the basis of design, a few of the principles must be adhered to:

BackgroundThe internet is awash with articles about restful APIs (for convenience, the "RESTful API" shorthand for "API" below), but there is no "universal" design standard: How to do authentication? What is the API format? Should your API include version information? When you start to write an app, especially when the

Web APIs has become a very important topic in the last year. We at M-way Solutions is working every day with different backend systems and therefore we know about the importance of a Clean API design.Typically we use a RESTful design for our web APIs. The concept of REST is to separate the APIs structure into logical resources. There is used the HTTP methods GET, DELETE, POST and PUT to operate with the resources.These is best

Web APIs have become more and more popular in recent years, and the simplicity of API design has become particularly important in multi-backend system interaction applications. In general, RESTful APIs are used as our Web API. This article describes some of the best practices for designing simple RESTful APIs.A noun used instead of a verbUsing nouns to define int

API test Best Practices-AuthenticationApplicable class: Advanced1. OverviewAuthentication is typically defined as an activity that confirms the identity of a resource, in which the identity of the resource refers to the consumer of the API (or, in other words, the caller). Once a user's authentication has passed, he will be granted access to resources or APIs tha
