A package to get the ECB exchange rates for use with Go (golang) services
Check a current exchange rate
package main
import (
"fmt"
"log"
"github.com/openprovider/ecbrates"
)
func main() {
r, err := ecbrates.New()
if err != nil {
log.Fatal("Error: ", err)
}
// Case 1: get dollar rate relative to euro
if value, ok := r.Rate[ecbrates.USD].(string); ok {
fmt.Println("Exchange rate", r.Date, ": EUR 1 -> USD", value)
}
// Case 2: convert of 100 euros to dollars
if value, err := r.Convert(100, ecbrates.EUR, ecbrates.USD); err == nil {
fmt.Println("Exchange rate", r.Date, ": EUR 100.0 -> USD", value)
}
// Case 3: convert of 100 dollars to yens
if value, err := r.Convert(100, ecbrates.USD, ecbrates.JPY); err == nil {
fmt.Println("Exchange rate", r.Date, ": USD 100.0 -> JPY", value)
}
}Show history of exchange rates for EUR -> USD
package main
import (
"fmt"
"log"
"github.com/openprovider/ecbrates"
)
func main() {
rates, err := ecbrates.Load() // 90 days history
// rates, err := ecbrates.LoadAll() // ALL history
if err != nil {
log.Fatal("Error: ", err)
}
for _, r := range rates {
if value, ok := r.Rate[ecbrates.USD].(string); ok {
fmt.Println("Exchange rate", r.Date, ": EUR 1 -> USD", value)
}
}
