Parameter for HTTP requests

The supported parameter extractors are explained below.

Query Parameter

The FromQuery extractor function provides a simple way to extract string, int, float64 and bool values from the query (www....com/item?query=xyz). In addition, Option provides additional features explained below.

import (
  "github.com/StevenCyb/goapiutils/extractor/http/request/parameter"
)
// ...

stringValue, err := parameter.FromQuery[string](req, parameter.Option{Key: "stringValue"})
intValue, err := parameter.FromQuery[int](req, parameter.Option{Key: "intValue"})
floatValue, err := parameter.FromQuery[float64](req, parameter.Option{Key: "floatValue"})
boolValue, err := parameter.FromQuery[bool](req, parameter.Option{Key: "boolValue"})

Path Parameter

The FromPath extractor function provides a simple way to extract string, int, and bool values from the URL path (www....com/item/{item_id}). In addition, Option provides additional features explained below.

import (
  "github.com/StevenCyb/goapiutils/extractor/http/request/parameter"
)
// ...

stringValue, err := parameter.FromPath[string](req, parameter.Option{Key: "stringValue"})
intValue, err := parameter.FromPath[int](req, parameter.Option{Key: "intValue"})
boolValue, err := parameter.FromPath[bool](req, parameter.Option{Key: "boolValue"})

Parameter Option

The Option argument for the From* extractors are similar. Available options:

• Key[string]: name of the parameter
• Required[bool]: mark parameter as required
