免费(po-jie) Google翻译接口源码 (不用*，在国内也可以访问，不过时间需要几秒钟)

源码来源
https://blog.csdn.net/hujingshuang/article/details/80178152

注：原文的代码没问题也齐全，不过小白可能会不明白 Google.js 在哪、怎么放？
针对小白我在最后面给出了工程源码 下载直接运行就可以验证使用

maven依赖

  <!-- https://mvnrepository.com/artifact/org.apache.httpcomponents/httpclient -->
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.5.12</version>
        </dependency>

Google.js

项目根目录下 新建个目录js , 然后新建一个文件 Google.js

代码中访问Google.js的路径: System.getProperty(“user.dir”) + “/js/Google.js”

Google.js 源码

function token(a) {
    var k = "";
    var b = 406644;
    var b1 = 3293161072;

    var jd = ".";
    var sb = "+-a^+6";
    var Zb = "+-3^+b+-f";

    for (var e = [], f = 0, g = 0; g < a.length; g++) {
        var m = a.charCodeAt(g);
        128 > m ? e[f++] = m : (2048 > m ? e[f++] = m >> 6 | 192 : (55296 == (m & 64512) && g + 1 < a.length && 56320 == (a.charCodeAt(g + 1) & 64512) ? (m = 65536 + ((m & 1023) << 10) + (a.charCodeAt(++g) & 1023),

        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }
}

运行结果 可以看到翻译内容: “Who am I, where am I?”,“我是谁，我在哪儿？”

最后，工程demo源码

当前能正常使用的时间点 2020-12-17 ，时间若太久了不知道接口会不会被河蟹，自己验证可用后再使用
