go-postman-collection

Go module to work with Postman Collections.

This module aims to provide a simple way to work with Postman collections. Using this module, you can create collections, update them and export them into the Postman Collection format v2 (compatible with Insomnia)

Postman Collections are a group of saved requests you can organize into folders. For more information about Postman Collections, you can visit the official documentation.

Examples

Collections

Read a Postman Collection

package main

import (
	"os"

	postman "github.com/rbretecher/go-postman-collection"
)

func main() {
	file, err := os.Open("postman_collection.json")
	defer file.Close()

	if err != nil {
		panic(err)
	}

	c, err := postman.ParseCollection(file)

	_ = c
}

Create and save a Postman Collection

package main

import (
	"os"

	postman "github.com/rbretecher/go-postman-collection"
)

func main() {
    c := postman.CreateCollection("My collection", "My awesome collection")

    c.AddItemGroup("A folder").AddItem(&postman.Item{
        Name:    "This is a request",
        Request: Request{
            URL: &URL{
                Raw: "http://www.google.fr",
            },
            Method: postman.Get,
        },
    })

    file, err := os.Create("postman_collection.json")
    defer file.Close()

    if err != nil {
        panic(err)
    }

    err = c.Write(file)

    if err != nil {
        panic(err)
    }
}

Items

Items are the basic unit for a Postman collection, it can either be a request (Item) or a folder (ItemGroup).

// Create a simple item.
item := postman.CreateItem(postman.Item{
    Name:    "A basic request",
    Request: Request{
        URL: &URL{
            Raw: "http://www.google.fr",
        },
        Method: postman.Get,
    }
})

// Create a simple folder.
folder := postman.CreateItemGroup(postman.ItemGroup{
    Name: "A folder",
})

// Add the item to the folder
folder.AddItem(item)

Request

Part of the Item, a Request represents an HTTP request.

// Basic request
req := Request{
    URL: &URL{
        Raw: "http://www.google.fr",
    },
    Method: postman.Get,
}

// Complex request
req := postman.Request{
    URL: &postman.URL{
        Raw: "http://www.google.fr",
    },
    Method: postman.Post,
    Body: &postman.Body{
        Mode: "raw",
        Raw:  "{\"key\": \"value\"}",
    },
}

Auth

Auth can be added to a Request or an ItemGroup.

// Create basic auth with username and password
auth := postman.CreateAuth(postman.Basic, postman.CreateAuthParam("username", "password"))

Variable

Variable can be added to Collection, Item, ItemGroup and URL.

v := postman.CreateVariable("env", "prod")
