使用auto.js写一个翻译小工具

本帖最后由 wwwwwllllk 于 2023-2-24 21:19 编辑

# 写这个工具的原因
1.在某款app，英语我看不懂，正常情况下它有翻译该段内容的按钮。但是有的时候就没有，我很困扰。每次都得复制出去打开一个app或者网页去翻译一下。很麻烦。

2.如何写英文，搜索输入法自带翻译功能(很nice)

但是它就没有英语转中文

# 思路，踩坑，以及疑惑点
1.我之前写的油猴脚本https://bbs.tampermonkey.net.cn/thread-2326-1-1.html ，思路一模一样(里面有一个MD5工具类这种就是复制过来的，所以不要被吓倒)
2.下面的代码我就把appId,key写为空了，需要的自己去百度翻译申请即可，免费的。
3.这个工具只是解决了我的需求，如果不满足，可以自己去写。
4.工具我用的是auto.jsPro(花钱买的总算是起了一次作用，它的vscode调试工具也比之前好了)，auto.js4才是无敌，pro几乎写不了针对tb,pdd,jd等脚本，因为无法对其布局分析，所以大家用auto.js4或者其它开源免费auto.js即可。

## 踩坑点
1.我觉得小白就时常会被一些信息干扰，但是我之前也是这样的。所以我简单的介绍一些东西方便大家入门。
2.auto.js官网 https://pro.autojs.org/docs/zh/v8/dialogs.html#dialogs-select-title-items-callback(auto.js4也就是之前开源的那一款，auto.jspro它们是有区别的，但是不影响我们使用)，引擎不一样，它们的区别就是类似于vue2,vue3,vue3兼容了vue2的写法，还衍生了一些新的写法。所以对于我们写一些小工具。我们就用之前的写法就可以。因为是兼容的。然后就是需要什么就去官方文档搜索里面输什么。不懂你在百度看看别人写的。

3. 说下我上面踩的坑。最开始我是没有加悬浮按钮，直接input框输入完成点确定调接口返回接口很顺利。为了用的顺手我加了悬浮按钮(我想让按钮移动，百度到一个复制过来报错了，我没找到解决方法，我就放到一个差不多的位置了)，然后就是悬浮按钮点击以后触发弹出input框这里又出问题了。input框还没输完，结框就出来了。

通过百度我发现
```
// 前面加ui以后顺序没问题，但是会在一个新的界面操作，把我app盖住了这肯定不行
// 去掉ui就有问题
"ui";
rawInput("请输入您的名字", "").then(name => {
alert("您的名字是" + name);
});
```

下面这样写就没问题了
```
rawInput("请输入您的名字", "", name => {
alert("您的名字是" + name);
});
```
4.打包apk安装包以后也不能用，我也不知道什么原因

# 代码
```
window = floaty.rawWindow(
<vertical>
   <button id="按钮"text="翻译" style="Widget.AppCompat.Button.Colored"/>
</vertical>
)
setInterval(() => {}, 1000);
window.setPosition(900, 500);

window.按钮.click(function(){
rawInput("请输入英语", "", inputWords => {
alert("结果为: " + translateContent(inputWords));
});
});

function translateContent(inputWords) {
var salt = new Date().getTime();
var appid = ""; // 写成自己的
var key = ""; // 写成自己的
if(!appid || !key){
   alert("请自己前往百度翻译平台网站申请appid和key是免费的，最好不要泄露，因为1秒只能调用一次。多人使用可能就会出现问题了")
}
var str1 = appid + inputWords + salt + key;
var sign = MD5(str1);
var from = "en";
var to = "zh";
const res = http.get(`http://api.fanyi.baidu.com/api/trans/vip/translate?q=${inputWords}&appid=${appid}&salt=${salt}&from=${from}&to=${to}&sign=${sign}`);
