Google Translation APIを使って翻訳

[hokada]

Google Translation API を使って翻訳をする方法です。

このGoogle Translation APIを利用するには、Google APIs ConsoleからAPI Keyを生成する必要があります。

Code:

{define-proc public {translate
                        version:int = 2,
                        key:String,
                        source:String,
                        source-locale:Locale,
                        target-locale:Locale
                    }:String
    def site =
        {format
            "https://www.googleapis.com/language/translate/v%i",
            version
        }
    def params =
        {format
            "key=%s&q=%s&source=%s&target=%s",
            key,
            {url-encode-string source},
            source-locale.name,
            target-locale.name
        }
    def target-url = {format "%s?%s", site, params}
    {with-open-streams
        tis = {read-open {url target-url}}
     do
        def json-val = {JsonValue-parse tis}
        {return
            || TODO: HTML decode
            {url-decode-string
                json-val["data"]["translations"][0]["translatedText"]
            }
        }
    }
}
