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,主要记录了go语言的一个关于简单翻译的项目

go语言 实战 简单翻译

将查询的单词序列化，查询返回一个json

代码转换网址curlconverter.com/#go

json转go结构体网址oktools.net/json2go

将上面返回的JSON通过结构体反序列化

代码如下

package main

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

   TransType string `json:"trans_type"`
   Source    string `json:"source"`
   UserID    string `json:"user_id"`
}

   Rc   int `json:"rc"`
   Wiki struct {
      KnownInLaguages int `json:"known_in_laguages"`

         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"`

   } `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"`
}
