eurlex-ws-go provides an implementation of the EUR-Lex Webservice (Search) in Go. The API is described here and here.
go get -u github.com/slipke/eurlex-ws-goCreate a simple query and call the API (replace <username> and <password> with your credentials):
import (
log "github.com/sirupsen/logrus"
"github.com/slipke/eurlex-ws-go"
)
func main() {
cfg := eurlex.NewConfig("<usename>", "<password>")
ws := eurlex.NewWebservice(cfg)
sr, err := ws.Search(
eurlex.NewSearchRequestFromString("DN~32014R1338 OR DN~32014R1337"),
)
if err != nil {
log.Fatalf("Failed to issue request: %s", err)
return
}
log.Printf(
"Returned %d elements (Page: %d, NumHits: %d, TotalHits: %d, Language: %s)",
len(sr.Result),
sr.Page,
sr.NumHits,
sr.TotalHits,
sr.Language,
)
for _, r := range sr.Result {
log.Printf("Result title: %s", r.Content.Notice.Expression.Title)
}
}eurlex.Config is used to configure your webservice, it has the following defaults:
Config{
...
Logger: logrus.StandardLogger(),
Client: http.DefaultClient,
}eurlex.SearchRequest is used to to query the API.
It has the following defaults:
SearchRequest{
Page: 1,
PageSize: 10,
SearchLanguage: "en",
}Page defines the current page, whereas PageSize defines the maximum numbers of results in the response. SearchLanguage defines the language of the results.
The structure of the returned SearchResult is derived from the returning XML. An example can be found in fixtures/result.xml. More information can be found under Resources.
