使用go构建彩云翻译的Alfred Workflow ｜ 青训营笔记

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：

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

效果如下：

如果上面的Gif动画加载不出来，可以看静态图：

image-20220508155914512

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 161421_SuAg4d

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 161504_JmrHgl

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：

package main

import (
	"bytes"
	"encoding/json"
	"fmt"
	"io/ioutil"
	"log"
	"net/http"
	"os"
)

type DictRequest struct {
	TransType string `json:"trans_type"`
	Source    string `json:"source"`
	UserID    string `json:"user_id"`
}

type DictResponse struct {
	Rc   int `json:"rc"`
	Wiki struct {
		KnownInLaguages int `json:"known_in_laguages"`
		Description     struct {
			Source string      `json:"source"`
			Target interface{} `json:"target"`
		} `json:"description"`
		ID   string `json:"id"`
		Item struct {
			Source string `json:"source"`
			Target string `json:"target"`
		} `json:"item"`
		ImageURL  string `json:"image_url"`
		IsSubject string `json:"is_subject"`
		Sitelink  string `json:"sitelink"`
	} `json:"wiki"`
	Dictionary struct {
		Prons struct {
			EnUs string `json:"en-us"`
			En   string `json:"en"`
		} `json:"prons"`
		Explanations []string      `json:"explanations"`
		Synonym      []string      `json:"synonym"`
		Antonym      []string      `json:"antonym"`
		WqxExample   [][]string    `json:"wqx_example"`
		Entry        string        `json:"entry"`
		Type         string        `json:"type"`
		Related      []interface{} `json:"related"`
		Source       string        `json:"source"`
	} `json:"dictionary"`
}

func query(word string) {
	client := &http.Client{}
	request := DictRequest{TransType: "en2zh", Source: word}
	buf, err := json.Marshal(request)
	if err != nil {
		log.Fatal(err)
	}
	var data = bytes.NewReader(buf)
	req, err := http.NewRequest("POST", "https://api.interpreter.caiyunai.com/v1/dict", data)
	if err != nil {
		log.Fatal(err)
	}
	req.Header.Set("Connection", "keep-alive")
	req.Header.Set("DNT", "1")
	req.Header.Set("os-version", "")
	req.Header.Set("sec-ch-ua-mobile", "?0")
	req.Header.Set("User-Agent", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.51 Safari/537.36")
	req.Header.Set("app-name", "xy")
	req.Header.Set("Content-Type", "application/json;charset=UTF-8")
	req.Header.Set("Accept", "application/json, text/plain, */*")
	req.Header.Set("device-id", "")
	req.Header.Set("os-type", "web")
	req.Header.Set("X-Authorization", "token:qgemv4jr1y38jyq6vhvi")
	req.Header.Set("Origin", "https://fanyi.caiyunapp.com")
	req.Header.Set("Sec-Fetch-Site", "cross-site")
	req.Header.Set("Sec-Fetch-Mode", "cors")
	req.Header.Set("Sec-Fetch-Dest", "empty")
	req.Header.Set("Referer", "https://fanyi.caiyunapp.com/")
	req.Header.Set("Accept-Language", "zh-CN,zh;q=0.9")
	req.Header.Set("Cookie", "_ym_uid=16456948721020430059; _ym_d=1645694872")
	resp, err := client.Do(req)
	if err != nil {
		log.Fatal(err)
	}
	defer resp.Body.Close()
	bodyText, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		log.Fatal(err)
	}
	if resp.StatusCode != 200 {
		log.Fatal("bad StatusCode:", resp.StatusCode, "body", string(bodyText))
	}
	var dictResponse DictResponse
	err = json.Unmarshal(bodyText, &dictResponse)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(word, "UK:", dictResponse.Dictionary.Prons.En, "US:", dictResponse.Dictionary.Prons.EnUs)
	for _, item := range dictResponse.Dictionary.Explanations {
		fmt.Println(item)
	}
}

func main() {
	if len(os.Args) != 2 {
		fmt.Fprintf(os.Stderr, `usage: simpleDict WORD
example: simpleDict hello
		`)
		os.Exit(1)
	}
	word := os.Args[1]
	query(word)
}

适配Alfred

为了适配Alfred，我们需要定义输出所需要的结构体：


// 用于翻译结果的图标显示
type icon struct {
	Type string `json:"type"`
	Path string `json:"path"`
}

// 用于单条结果
type item struct {
	Subtitle string `json:"subtitle"` // 固定的小字的标题
	Title    string `json:"title"`
	Arg      string `json:"arg"`
	Icon     icon   `json:"icon"`
}

// 结果集
type items struct {
	Items []item `json:"items"`
}

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：

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

    errItems := items{Items: errItem}
    itemsJson, _ := json.Marshal(errItems)
    fmt.Println(string(itemsJson))
    return
}

然后是结果通过json.Marshal序列化后输出，以英译汉为例：

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

func IsChinese(str string) bool {
	var count int
	for _, v := range str {
		if unicode.Is(unicode.Han, v) {
			count++
			break
		}
	}
	return count > 0
}

func main() {
	if len(os.Args) != 2 {
		//		fmt.Fprintf(os.Stderr, `usage: simpleDict WORD
		//example: simpleDict hello
		//		`)
		os.Exit(1)
	}
	word := os.Args[1]
	icon := icon{Type: "file", Path: "logo2.png"}
	if !IsChinese(word) {
		queryEnglish(word, icon)
	} else {
		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！
