Examples

Quick testing

    package main

    import (
        "github.com/johnbalvin/gozon"
    )
    func main(){
        //you need to have write permissions, the result will be save inside folder "test"
        gozon.Test()
    }

Basic data

    package main

    import (
        "encoding/json"
        "log"
        "os"
        "github.com/johnbalvin/gozon"
    )
    func main(){
        //you need to have write permissions, the result will be save inside folder "test"
        if err := os.MkdirAll("./test", 0644); err != nil {
            log.Println("test 1 -> err: ", err)
            return
        }
        productURL:="https://www.amazon.com/[label]/dp/[id]?th=1&psc=1"
        client := gozon.DefaulClient()
        data, _, err := client.GetFromURL(productURL)
        if err != nil {
            log.Println("test:2 -> err: ", err)
            return
        }
        f, err := os.Create("./test/data.json")
        if err != nil {
            log.Println("test:3 -> err: ", err)
            return
        }
        json.NewEncoder(f).Encode(data)
    }

Basic data and images

    package main

    import (
        "encoding/json"
        "log"
        "os"
        "github.com/johnbalvin/gozon"

        if err := os.MkdirAll("./test/images", 0644); err != nil {
            log.Println("test 1 -> err: ", err)
            return
        }
        productURL:="https://www.amazon.com/[label]/dp/[id]?th=1&psc=1"
        client := gozon.DefaulClient()

        data, _, err := client.GetFromURL(productURL)
        if err != nil {
            log.Println("test:2 -> err: ", err)
            return
        }
        if err := data.SetImages(client.ProxyURL); err != nil {
            log.Println("test:3 -> err: ", err)
            return
        }
		for j, imgs := range data.Images {
			if len(imgs.Large.Content) != 0 {
				f_name1 := fmt.Sprintf("./test/images/%d_large%s", j, imgs.Large.Extension)
				os.WriteFile(f_name1, imgs.Large.Content, 0644)
			}

			}
		}
        f, err := os.Create("./test/data.json")
        if err != nil {
            log.Println("test:4 -> err: ", err)
            return
        }
        json.NewEncoder(f).Encode(data)
    }

With proxy

        "os"
        "github.com/johnbalvin/gozon"

            log.Println("test:1 -> err: ", err)
            return
        }
        //You need to place the country code, otherwise it will amazon will get it from the IP
        client := gozon.NewClient("US","MXN", proxyURL, 6)
        productsURLs, _, err := client.GetMainURLs()
        data, _, err := client.GetFromURL(productURL)
        if err != nil {
            log.Println("test:2 -> err: ", err)

        }

            log.Println("test:3 -> err: ", err)
            return
        }
        for j, imgs := range data.Images {
            if len(imgs.Large.Content) != 0 {

            if len(imgs.Thumb.Content) != 0 {
                f_name2 := fmt.Sprintf("./test/images/%d_thumb%s", j, imgs.Thumb.Extension)
                os.WriteFile(f_name2, imgs.Thumb.Content, 0644)

            return
        }
        json.NewEncoder(f).Encode(data)
