以前写了一个每日推送的英文小程序:brainyQuoteLite 有兴趣的小伙伴可以扫码体验一下。

接入百度翻译API,首先你先注册一个开发者:

注册百度翻译开发者

然后选择你要的翻译服务,我的是通用翻译,你会有一个appid和key,请求API的时候需要对参数进行md5,后面会有例子。

备注:这个模板是网上找的。这里包装了一下异步的函数,这样就方便在别的地方调用了。

import md5 from './md5.js'

const appid = ''  //注册百度翻译api
const key = ''    //注册百度翻译api

function translate(q, from='en',to='zh') {
  // { from = 'auto', to = 'auto' } = { from: 'auto', to: 'auto' } 表示默认传递参数传递的值
  //Promise 对象
  return new Promise((resolve, reject) => {
    let salt = Date.now()  //随机数
    let sign = md5(`${appid}${q}${salt}${key}`)  //拼接 MD5进行加密
    wx.request({
      url: 'https://fanyi-api.baidu.com/api/trans/vip/translate',
      data: {
        q,  //待翻译文本
        from,  //待翻译的原始语言
        to,   //待翻译成的目标语言
      appid,
        salt,  //随机数
        sign   //拼接 MD5进行加密
      },
      success(res) {
        console.log(res)
        if (res.data && res.data.trans_result) {
          resolve(res.data)
        } else {
          reject({ status: 'error', msg: '翻译失败' })
          wx.showToast({
            title: '翻译失败',
            icon: 'none',
            duration: 3000
          })
        }
      },
      fail() {
        reject({ status: 'error', msg: '翻译失败' })
        wx.showToast({
          title: '网络异常',
          icon: 'none',
          duration: 3000
        })
      }
    })
  })
}
module.exports.translate = translate

调用

 translate(xxx).then((res)=>{
            console.log(res);
            _this.setData({
              translate:res.trans_result[0].dst
            })
          }).catch((error)=>{
            console.log('tanslate error!')
            console.log(error)
          })

null

好了。
