HTTP methods (GET and POST)

HTTP methods are the standard actions used to perform operations on web servers. Within the context of building APIs or distributed systems, two of the most fundamental methods are GET and POST^[400-devops__09-Scripting-Language__golang__introduction__part-3.http__readme.md].

The GET method is primarily used to request data from a specified resource^[400-devops__09-Scripting-Language__golang__introduction__part-3.http__readme.md]. It is the default mechanism for retrieving information, such as fetching a list of items or a specific record, where the request parameters are typically encoded in the URL^[400-devops__09-Scripting-Language__golang__introduction__part-3.http__readme.md].

The POST method is designed to send data to a server to create or update a resource^[400-devops__09-Scripting-Language__golang__introduction__part-3.http__readme.md]. Unlike GET, requests using this method often include a payload (e.g., JSON data) in the request body, making it suitable for operations that require submitting complex data structures to the server^[400-devops__09-Scripting-Language__golang__introduction__part-3.http__readme.md].

When implementing these methods, it is crucial to validate the request type and handle errors appropriately. For example, if a server endpoint defines a specific operation for POST but receives a different HTTP method, the server should return a 405 Method Not Allowed status code^[400-devops__09-Scripting-Language__golang__introduction__part-3.http__readme.md].
