首先我们需要一个合适的API，这里就用和老师相同的彩云翻译

然后随便输入一个单词点击翻译后右键点击检查在NetWork下寻找到有Payload和Preview的dict，如图：

再接着右键dict->Copy->Copy as cURL(或者Copy as cURL(bash))

将Curl的POST请求转换为Go语言的代码，是为了在Go语言中实现与Curl相同的功能。这样可以在Go语言中发送POST请求，并使用Go语言的特性和库进行处理和处理响应数据。

使用curlconverter.com/go/ 网站将curl命令转化为go语言代码。

package main import ( "fmt" "io" "log" "net/http" "strings" ) func main() { client := &http.Client{} var data = strings.NewReader(`{"trans_type":"en2zh","source":"good"}`) req, err := http.NewRequest("POST", "https://api.interpreter.caiyunai.com/v1/dict", data) if err != nil { log.Fatal(err) } req.Header.Set("authority", "api.interpreter.caiyunai.com") req.Header.Set("accept", "application/json, text/plain, */*") req.Header.Set("accept-language", "zh-CN,zh;q=0.9") req.Header.Set("app-name", "xy") req.Header.Set("content-type", "application/json;charset=UTF-8") req.Header.Set("device-id", "2cb44afb42b380444a568eeef2f0c398") req.Header.Set("origin", "https://fanyi.caiyunapp.com") req.Header.Set("os-type", "web") req.Header.Set("os-version", "") req.Header.Set("referer", "https://fanyi.caiyunapp.com/") req.Header.Set("sec-ch-ua", `"Not/A)Brand";v="99", "Google Chrome";v="115", "Chromium";v="115"`) req.Header.Set("sec-ch-ua-mobile", "?0") req.Header.Set("sec-ch-ua-platform", `"Windows"`) req.Header.Set("sec-fetch-dest", "empty") req.Header.Set("sec-fetch-mode", "cors") req.Header.Set("sec-fetch-site", "cross-site") req.Header.Set("user-agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/115.0.0.0 Safari/537.36") req.Header.Set("x-authorization", "token:qgemv4jr1y38jyq6vhvi") resp, err := client.Do(req) if err != nil { log.Fatal(err) } defer resp.Body.Close() bodyText, err := io.ReadAll(resp.Body) if err != nil { log.Fatal(err) } fmt.Printf("%s\n", bodyText) }

再根据这curl命令生成的go代码来写request body。

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"`
}

func main() {
   client := &http.Client{}
   //var data = strings.NewReader(`{"trans_type":"en2zh","source":"good"}`)
   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)
   }
}

再去复制respond的json使用oktools.net/json2go 网站转换为go语言的map结构。

type AutoGenerated struct {
	Rc int `json:"rc"`
	Wiki struct {
	} `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"`
}

最后将它放入我们的代码中，最终代码。

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 {
   } `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{}
   //var data = strings.NewReader(`{"trans_type":"en2zh","source":"good"}`)
   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("authority", "api.interpreter.caiyunai.com")
   req.Header.Set("accept", "application/json, text/plain, */*")
   req.Header.Set("accept-language", "zh-CN,zh;q=0.9")
   req.Header.Set("app-name", "xy")
   req.Header.Set("content-type", "application/json;charset=UTF-8")
   req.Header.Set("device-id", "2cb44afb42b380444a568eeef2f0c398")
   req.Header.Set("origin", "https://fanyi.caiyunapp.com")
   req.Header.Set("os-type", "web")
   req.Header.Set("os-version", "")
   req.Header.Set("referer", "https://fanyi.caiyunapp.com/")
   req.Header.Set("sec-ch-ua", `"Not/A)Brand";v="99", "Google Chrome";v="115", "Chromium";v="115"`)
   req.Header.Set("sec-ch-ua-mobile", "?0")
   req.Header.Set("sec-ch-ua-platform", `"Windows"`)
   req.Header.Set("sec-fetch-dest", "empty")
   req.Header.Set("sec-fetch-mode", "cors")
   req.Header.Set("sec-fetch-site", "cross-site")
   req.Header.Set("user-agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/115.0.0.0 Safari/537.36")
   req.Header.Set("x-authorization", "token:qgemv4jr1y38jyq6vhvi")
   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))
   }
   //fmt.Printf("%s\n", bodyText)
   var dictResponse DictResponse
   err = json.Unmarshal(bodyText, &dictResponse)
   if err != nil {
      log.Fatal(err)
   }
   //fmt.Printf("%#v\n", dictResponse)
   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.Println(os.Stderr, `usage: simpleDict WORD
example: simpleDict hello
      `)
      os.Exit(1)
   }
   word := os.Args[1]
   query(word)
}

在终端使用go run来运行代码，如图。

这里将它用一个函数封装起来了，更方便我们的使用。
