前言
实现功能:输入一个英文单词,返回翻译及其英标。
这个项目非常简单,本文的主要目的是记录两个网站(curl语句转换成golang代码,json结构体转go结构体),留着以后直接用。
抓包
首先随便去一个翻译网站抓个包,这里我去的是彩云小译,然后随便输入一个单词,去找前端发送给后端的请求。
这里copy的内容是:
curl 'https://api.interpreter.caiyunai.com/v1/dict' \ -H 'Connection: keep-alive' \ -H 'os-version: ' \ -H 'User-Agent: Mozilla/5.0 (Linux; Android) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.109 Safari/537.36 CrKey/1.54.248666' \ -H 'app-name: xy' \ -H 'Content-Type: application/json;charset=UTF-8' \ -H 'Accept: application/json, text/plain, */*' \ -H 'device-id: ' \ -H 'os-type: web' \ -H 'X-Authorization: token:qgemv4jr1y38jyq6vhvi' \ -H 'Origin: https://fanyi.caiyunapp.com' \ -H 'Sec-Fetch-Site: cross-site' \ -H 'Sec-Fetch-Mode: cors' \ -H 'Sec-Fetch-Dest: empty' \ -H 'Referer: https://fanyi.caiyunapp.com/' \ -H 'Accept-Language: zh-CN,zh;q=0.9' \ --data-raw '{"trans_type":"en2zh","source":"good"}' \ --compressed
解析成go代码
这个时候我们去这个网页:Convert curl commands to Python, JavaScript, PHP, R, Go, Rust, Elixir, Java, MATLAB, Dart, CFML, Ansible URI, Strest or JSON,将复制的内容粘贴到里面,就能得到go的代码了!
下面的代码都是网页解析curl自动生成的
package main import ( "fmt" "io/ioutil" "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("Connection", "keep-alive") req.Header.Set("User-Agent", "Mozilla/5.0 (Linux; Android) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.109 Safari/537.36 CrKey/1.54.248666") 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("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") 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) } fmt.Printf("%s\n", bodyText) }
json转go结构体
运行程序后,我们发现返回的是json,我们需要将json反序列化到go的结构体中

这么多的嵌套,手写岂不累死,这时就去第二个网页:JSON转Golang Struct
可以发现结构体已经生成好了,我们只需要将结构体赋值到代码中,进行反序列化即可
输入看看效果

此时就输出好了,后续可以将单词替换成输入的单词,输入替换成翻译和英标即可。
重点
本文的重点在于crul转go代码和json转go结构体的两个工具的使用,我记得之前写一个项目的时候,手写es返回的json结构体,居然忘记了找工具去转换,心塞。
