最近参加了字节跳动的后端专场青训营，是一个免费的Go培训项目，正好最近入职了字节跳动的安全与风控部门，负责公司的业务安全(电商SDLC)，公司大部分业务以Go为主，借此青训营机会希望也可以提升一下自己的Go后端开发水平，更好的为公司工作。

按照青训营要求，每个学员为了顺利结业需参加笔记创作活动，这是我的第一篇笔记，首发于掘金社区。

以下是正文

这是我参与「第三届青训营 -后端场」笔记创作活动的的第1篇笔记

前言▸

在Day1的『Go语言上手-基础语言』中，老师给了三个项目，其中一个是基于彩云翻译使用Go来实现一个建议的词典查询功能，代码支持英译汉。我发现彩云翻译很好用，不需要自己申请api就可以使用，于是我在此基础上加以改造，将其做成了一个Alfred Workflow，并且添加了中译英的功能。

AlfredWorkflow初体验▸

Alfred是MacOS上提升工作效率的工具。关于Alfred可以看我博客的两篇文章：

• Alfred 4: MacOS效率提升大杀器（上篇）
• Alfred 4: MacOS效率提升大杀器（下篇）

可以在我的github下载到这次的彩云翻译Workflow: https://github.com/y1nglamore/caiyunTranslator

效果如下：

如果上面的Gif动画加载不出来，可以看静态图：

使用方法▸

首先去我的github仓库下载彩云翻译.alfredworkflow

双击导入Alfred，然后双击这个Script Filter

将命令中的go的绝对路径改成你本机的绝对路径，可以用whereis go查看

然后只需要在Alfred中输入cy xxx即可。这里如果xxx是英文就是英译汉，如果是中文就是汉译英。

构造思路▸

代码▸

首先老师给的版本是这样的：

适配Alfred▸

为了适配Alfred，我们需要定义输出所需要的结构体：

代码语言：javascript复制

<span class="hljs-comment">// 用于翻译结果的图标显示</span>
<span class="hljs-keyword">type</span> icon <span class="hljs-keyword">struct</span> {
	Type <span class="hljs-keyword">string</span> <span class="hljs-string">`json:"type"`</span>
	Path <span class="hljs-keyword">string</span> <span class="hljs-string">`json:"path"`</span>
}

<span class="hljs-comment">// 用于单条结果</span>
<span class="hljs-keyword">type</span> item <span class="hljs-keyword">struct</span> {
	Subtitle <span class="hljs-keyword">string</span> <span class="hljs-string">`json:"subtitle"`</span> <span class="hljs-comment">// 固定的小字的标题</span>
	Title    <span class="hljs-keyword">string</span> <span class="hljs-string">`json:"title"`</span>
	Arg      <span class="hljs-keyword">string</span> <span class="hljs-string">`json:"arg"`</span>
	Icon     icon   <span class="hljs-string">`json:"icon"`</span>
}

<span class="hljs-comment">// 结果集</span>
<span class="hljs-keyword">type</span> items <span class="hljs-keyword">struct</span> {
	Items []item <span class="hljs-string">`json:"items"`</span>
}

然后将输出都以特定的json形式（具体什么形式可以看我博客的Alfred 4: MacOS效率提升大杀器（下篇）的介绍）输出，首先是报错时候的输出：

代码语言：javascript复制

<span class="hljs-comment">// 发生错误时的结果</span>
<span class="hljs-keyword">if</span> resp.StatusCode != <span class="hljs-number">200</span> {
    <span class="hljs-comment">//log.Fatal("bad StatusCode:", resp.StatusCode, "body", string(bodyText))</span>
    <span class="hljs-keyword">var</span> errItem []item
    errItem = []item{
        {
            Subtitle: <span class="hljs-string">"error"</span>,
            Title:    <span class="hljs-string">"bad StatusCode: "</span>   strconv.FormatInt(<span class="hljs-keyword">int64</span>(resp.StatusCode), <span class="hljs-number">10</span>),
            Arg:      <span class="hljs-string">"bad StatusCode: "</span>   strconv.FormatInt(<span class="hljs-keyword">int64</span>(resp.StatusCode), <span class="hljs-number">10</span>),
            Icon:     icon,
        },
    }

    errItems := items{Items: errItem}
    itemsJson, _ := json.Marshal(errItems)
    fmt.Println(<span class="hljs-keyword">string</span>(itemsJson))
    <span class="hljs-keyword">return</span>
}

然后是结果通过json.Marshal序列化后输出，以英译汉为例：

代码语言：javascript复制

<span class="hljs-keyword">var</span> resultItem []item
resultItem = []item{
    {
        Subtitle: <span class="hljs-string">"音标"</span>,
        Title:    <span class="hljs-string">"EN:"</span>   dictResponse.Dictionary.Prons.En   <span class="hljs-string">" US:"</span>   dictResponse.Dictionary.Prons.EnUs,
        Arg:      <span class="hljs-string">"EN:"</span>   dictResponse.Dictionary.Prons.En   <span class="hljs-string">" US:"</span>   dictResponse.Dictionary.Prons.EnUs,
        Icon:     icon,
    },
}
<span class="hljs-keyword">for</span> i, paraphrase := <span class="hljs-keyword">range</span> dictResponse.Dictionary.Explanations {
    paraphraseItem := item{Subtitle: <span class="hljs-string">"解释"</span>   strconv.FormatInt(<span class="hljs-keyword">int64</span>(i <span class="hljs-number">1</span>), <span class="hljs-number">10</span>), Title: paraphrase, Arg: <span class="hljs-string">"解释"</span>   strconv.FormatInt(<span class="hljs-keyword">int64</span>(i <span class="hljs-number">1</span>), <span class="hljs-number">10</span>), Icon: icon}
    resultItem = <span class="hljs-built_in">append</span>(resultItem, paraphraseItem)
}
resultItems := items{Items: resultItem}
resultJson, _ := json.Marshal(resultItems)
fmt.Println(<span class="hljs-keyword">string</span>(resultJson))

最后写两个函数，通过网上抄的IsChinese()判断是否字符串含有中文，如果含有中文就是汉译英，否则英译汉：

代码语言：javascript复制

<span class="hljs-function"><span class="hljs-keyword">func</span> <span class="hljs-title">IsChinese</span><span class="hljs-params">(str <span class="hljs-keyword">string</span>)</span> <span class="hljs-title">bool</span></span> {
	<span class="hljs-keyword">var</span> count <span class="hljs-keyword">int</span>
	<span class="hljs-keyword">for</span> _, v := <span class="hljs-keyword">range</span> str {
		<span class="hljs-keyword">if</span> unicode.Is(unicode.Han, v) {
			count  
			<span class="hljs-keyword">break</span>
		}
	}
	<span class="hljs-keyword">return</span> count &gt; <span class="hljs-number">0</span>
}

<span class="hljs-function"><span class="hljs-keyword">func</span> <span class="hljs-title">main</span><span class="hljs-params">()</span></span> {
	<span class="hljs-keyword">if</span> <span class="hljs-built_in">len</span>(os.Args) != <span class="hljs-number">2</span> {
		<span class="hljs-comment">//		fmt.Fprintf(os.Stderr, `usage: simpleDict WORD</span>
		<span class="hljs-comment">//example: simpleDict hello</span>
		<span class="hljs-comment">//		`)</span>
		os.Exit(<span class="hljs-number">1</span>)
	}
	word := os.Args[<span class="hljs-number">1</span>]
	icon := icon{Type: <span class="hljs-string">"file"</span>, Path: <span class="hljs-string">"logo2.png"</span>}
	<span class="hljs-keyword">if</span> !IsChinese(word) {
		queryEnglish(word, icon)
	} <span class="hljs-keyword">else</span> {
		queryChinese(word, icon)
	}
}

后记▸

第一天的知识比较简单，也没啥可记的，所以就分享一个我自己做的小工具吧。Alfred是真的神器，推荐用mac的同学都来试试，真的会爱不释手。

最后推荐一个我常用的翻译Workflow：有道翻译 超级好用，强烈推荐！
