TexTraの翻訳 APIをJavaScriptだけで取得する

Last updated at Posted at 2022-08-27

Web API の JavaScript での取得方法について の質問があったので作ってみました。

See the Pen TexTra 翻訳 Demo by John Doe (@04) on CodePen.

async function handle(e) {
  name = "extra";
  key = "5b37d68901799f71e8937f26add0fafd06309732b";
  secret = "71d1b17cfdc7e26e6232a9a750c038d2";
  text = e.target.value;

  const oauth = OAuth({
    consumer: { key, secret },
    signature_method: "HMAC-SHA1",
    hash_function(base_string, key) {
      return CryptoJS.HmacSHA1(base_string, key).toString(CryptoJS.enc.Base64);
    }
  });

  const options = {
    url: "https://mt-auto-minhon-mlt.ucri.jgn-x.jp/api/mt/generalNT_en_ja/",
    method: "POST",
    data: { text, name, key, type: "json" }
  };

  const cors_support = "https://corsproxy.io/?";
  const res = await fetch(cors_support + options.url, {
    method: options.method,
    body: new URLSearchParams(options.data),
    headers: oauth.toHeader(oauth.authorize(options))
  }).then((r) => r.json());
  document.all.output.value = res.resultset.result.text;
}

Python

Pythonでもpipで簡単にインストールできるようにしてみました。

pip install textra
