Generic https://rest.gadventures.com G API Document datatype

It extracts the common code for dealing with resource (JSON) "documents" from the G API.

Features include

• Calculating checksums (ETag)
• Specific behaviour on how the G API de/serializes JSON (e.g. nil slices are [], not null)
• Equal method to be able to compare one Document to another
• Binary serialization, which is faster than JSON and thanks to golang/snappy, results in smaller payload size
• Evaluating if the response is a GAPIError

The core datatype Document, is an alias for map[string]interface{}. While this will be slower than using custom structs, the tradeoff is that Document instances do not require customization based on the requested resource. In other words adding/removing attributes from G API resources does not require modifications to the gadventures/apidoc module.

Usage

specify the following in your go.mod file

require github.com/gadventures/apidoc v0.2.0

Example

package main

import (
	"encoding/json"
	"log"

	"github.com/gadventures/apidoc"
)

const blob := `{
    "street": "Stand 1385",
    "city": "Victoria Falls",
    "country": {
        "id": "ZW",
        "href": "https://rest.gadventures.com/countries/ZW",
        "name": "Zimbabwe"
    }
}`

func main() {
	doc = apidoc.New()
	err := json.Unmarshal([]byte(blob), &doc)
	if err != nil {
		log.Fatal(err.Error())
	}
	
	fmt.Println(doc["city"].(string)) // will print "Victoria Falls"
	
	id, ok := doc.GetPath("country", "id")
	if !ok {
		log.Fatal("could not find country.id in document")
	}
	fmt.Println(countryID.(string)) // will print "ZW"
}

NOTE

This library can be combined with gadventures/httpclient to build a rudimentary REST Client in Go for the G API.
