Configuration

Credentials

DADATA_API_KEY and DADATA_SECRET_KEY environment variables are used by default to authenticate client.

Custom credential provider may be used by implementing client.CredentialProvider interface.

Also, there is a "simple" credential provider client.Credentials you may utilize.

creds := client.Credentials{
    ApiKeyValue:    "<YOUR_API_KEY>",
    SecretKeyValue: "<YOUR_SECRET_KEY>",
}

api := NewSuggestApi(client.WithCredentialProvider(&creds))

HTTP client

HTTP client may be overridden with custom one:

httpClient := &http.Client{}

api := NewSuggestApi(WithHttpClient(httpClient))

Low level client usage

Pass and consume raw bytes/strings:

    endpointUrl, err := url.Parse("https://suggestions.dadata.ru/suggestions/api/4_1/rs/")
    if err != nil {
        return
    }

    cli := client.NewClient(endpointUrl,
        client.WithEncoderFactory(encoder.RawEncoderFactory()),
        client.WithDecoderFactory(encoder.RawDecoderFactory()),     
    )

    request := bytes.NewBufferString("{ \"query\": \"москва хабар\" }")
    response := &bytes.Buffer{}

    err = cli.Post(context.Background(), "suggest/address", request, response)
    if err != nil {
        return
    }

    fmt.Print(response.String()) // Output: `{"suggestions":[{"value":"г Москва, ул Хабаровская",...`
