Project Archived

Youdao has deployed a new frontend which uses Webpack and I have no time to make my crawler adapt to it.
So, this project is permanently ARCHIVED, or I'll back if I need this again.

Notably, the old translator API seems unchanged.
If you're trying to make another crawler, this repo and youdao.max.js may be helpful.

Youdao4J

Translating texts via Youdao Translator by one class.
Need GSON.

Usage

Youdao4J did lots of works in the background. DO NOT create morr Youdao4J Object.
Token expiration or cookie expiration are held automatically.

import java.util.concurrent.CompletableFuture;

public class Showcase {
    {
        var yd = Youdao4J.fromDefault(); // The default one is lazy-loaded and cached in memory.
        var advancedYd = Youdao4J.from(HttpClient.newBuilder(), Duration.ofMinutes(30), "Firefox UA ..?"); // If you need to specific User-Agent, HTTP Proxy, Cache-Control etc.
        yd.translate(Youdao4J.LanguageType.AUTO, Youdao4J.LanguageType.CHINESE, "Nullcat sb"); // Translate synchronously.
        CompletableFuture<String> future = yd.translateAsync(Youdao4J.LanguageType.AUTO, Youdao4J.LanguageType.CHINESE, "Nullcat sb"); // Translate Asynchronously. Threads are held by Http Clients
        future.thenAccept(System.out::println); // Print the result.

        Assertions.assertEquals(Youdao4J.fromDefault(), Youdao4J.fromDefault()); // They're equal.
    }
}
