Remote - basic principle introduction

Remote— Introduction to basic principles

background

When we write test cases everyday , It is inevitable that there is a need to obtain data from the server ,RF The framework itself is based on Python A layer of encapsulation , It is not friendly to complex interaction and coding , Therefore, the official provides a Remote To help us improve this situation , You can execute background methods like keywords , It is convenient for us to simplify complex calls .

Remote Principle

Remote The principle of is actually to use HTTP Request to a background service , Get a return result after executing the logic of the background service , actually , Write one yourself HTTP The service then parses the return value , With the use Remote It's the same .

The official logic diagram is like this .

The difference between them is Remote It uses XML-RPC, And we generally HTTP Most of them use JSON.

Because it's based on HTTP Protocol to communicate , So this way can cross language , such as RobotFramework Is based on Python Of , It's easy to call Python The library of , But if the business service is Java, And you need to do some encryption logic when requesting , Then it is best to directly call the encryption method of the business , without Remote&#
