通过go语言编写百度翻译API实现中印地文翻译功能

package main

import (
    "fmt"
    "io/ioutil"
    "net/http"
    "strings"
)

func translate(text string) (string, error) {
    url := "http://api.fanyi.baidu.com/api/trans/vip/translate"

    data := make(map[string]string)
    data["q"] = text
    data["from"] = "auto"
    data["to"] = "zh"

    params := []string{}
    for key, value := range data {
        params = append(params, key+"="+value)
    }

    appid := "your_appid"
    secretKey := "your_secretkey"
    salt := "1435660288"

    sign := appid + text + salt + secretKey
    signMd5 := md5.Sum([]byte(sign))
    signStr := fmt.Sprintf("%x", signMd5)

    params = append(params, "appid="+appid)
    params = append(params, "salt="+salt)
    params = append(params, "sign="+signStr)

    body := strings.NewReader(strings.Join(params, "&"))
    resp, err := http.Post(url, "application/x-www-form-urlencoded", body)
    if err != nil {
        return "", err
    }

    defer resp.Body.Close()
    bb, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        return "", err
    }

    return string(bb), nil
}

func main() {
    text := "Hello, world!"

    result, err := translate(text)
    if err != nil {
        fmt.Println("翻译失败：", err)
        return
    }

    fmt.Println("翻译结果：", result)
}
