Message distribution mechanism for work queues

The last blog post briefly introduced the basics of RABBITMQ and wrote a classic language starter program--helloworld. In this blog post we will create a Task Force column to distribute time-consuming tasks among workers (consumer). It is also an example of a translated website. Task Force Column

In the previous blog post, we completed a simple send and receive message program for the declared queue. Below we will create a work queue to distribute time-consuming tasks to multiple workers (consumer).

The primary task of the Work queue (aka: Task queue) is to avoid immediately doing a resource-intensive task that must wait for completion. Instead, we do task scheduling: encapsulate the task as a message and send it to the queue. The worker running in the background (consumer) takes it out and executes it eventually. When you run multiple workers (consumer), the tasks in the queue are worked on for shared execution.

Such a concept is useful for Web applications that handle complex tasks in a request window for an HTTP short link.

prepare to use the Thread.Sleep () method to simulate time-consuming. Use the number of decimal points to represent the complexity of the task. Each point will live in a 1s "work". For example, Hello ... It takes 3s of time to finish processing.
