篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Java 调用翻译软件实现英文文档翻译相关的知识,希望对你有一定的参考价值。

前言:

因最近要进行OCP的考试准备。看着大堆英文文档确实有些疼痛。又因文档内容有点大,又需要逐一去翻译 又很费时费力。于是 百度了一番,找到一些 可以使用Java来调用百度翻译软件的API( 注:(官方标注)每月前200万字不要钱,49元/月) 。于是就自己手动的修改了一番。然后就使用。


Java调用百度API实现翻译


百度官方API 访问地址:http://api.fanyi.baidu.com/api/trans/product/apidoc

百度官方计费声明:

下面是Java调用百度API实现翻译的具体步骤:

一、在写代码之前先在在百度翻译平台中,申请APP_ID 

申请地址申请的详见 点击打开链接

申请之后,会得到APP_ID和SECURITY_KEY

二、java代码如下

Java 破解谷歌翻译 免费 api 调用


注 :本文来源于《Java 破解谷歌翻译 免费 api 调用

在公司大佬的指点下, 写了个破解谷歌翻译的工具类,能破解谷歌翻译, 思路如下:

1 获取 tkk 
2 根据 tkk,和 输入内容 获取 tk 
3 根据 word,tk ,组装 url 访问 谷歌翻译 api

调用如下:

public static void main(String[] args) {
        /*GoogleApi googleApi = new GoogleApi();*/
        GoogleApi googleApi = new GoogleApi("122.224.227.202", 3128);
        String result = googleApi.translate("Many applications within the enterprise domain ", "", "zh");
        System.out.println(result);
    }
