java?百度翻譯工具類?分別有前端和后端的?例子及工具

使用百度翻譯接口需要網上申請key，代碼里面有URL。

前端翻譯 js info要查詢的信息 result拿到的結果

var query=info;var appid = '20180626000180267';var key = 'SwHMdwzocdsLMYPJ4M08';var salt = (new Date).getTime();var temp;// 多個query可以用\n連接 如 query='apple\norange\nbanana\npear'var from = 'auto';var to = 'zh';var str1 = appid + query + salt +key;var sign = MD5(str1);$.ajax({url: 'http://api.fanyi.baidu.com/api/trans/vip/translate',type: 'get',dataType: 'jsonp',data: {q: query,appid: appid,salt: salt,from: from,to: to,sign: sign},success: function (data) {result= data.trans_result[0].dst;} });}
