Google 翻译(中英,英中)

网上找了好久, 终于弄好了, 免费的谷歌翻译,直接上代码,不懂留言:

//翻译
app.get('/google', function (req, res, next) {
    var content = req.query.content;

    //请求查找TKK中的数值(可以当爬虫使用)
    superagent
        .get('https://translate.google.cn/?hl=en')
        .end(function (err, sres) { // callback
            /**设置响应头允许ajax跨域访问**/
            res.setHeader("Access-Control-Allow-Origin", "*");
            /*星号表示所有的异域请求都可以接受，*/
            res.setHeader("Access-Control-Allow-Methods", "GET,POST");
            // 常规的错误处理
            if (err) {
                return next(err);
            }
            var str = sres.text;
            console.log(str);
            var str1 = str.split('TKK')[1].substring(20, 79);//得到TKK附近的字符串
            var a = str1.match(/3d(\S*);/)[1];
            var b = str1.substring(15, 74).match(/3d(\S*);/)[1];
            var c = str1.substring(29, 74).match(/return (\S*)\+/)[1];
            var tkd = c + '.' + ((a - 0) + (b - 0));
            //得到TK的值
            var myTk = tk(content, tkd);
            // console.log(a + "\n" + b + "\n" + c + "\n" + myTk);
            var url_google = "";
            if (/^[a-zA-Z]*$/.test(content)) {
                console.log("英文" + content);
                url_google = "https://translate.google.cn/translate_a/single?client=t&sl=en&tl=zh-CN&hl=en&dt=at&dt=bd&dt=ex&dt=ld&dt=md&dt=qca&dt=rw&dt=rm&dt=ss&dt=t&ie=UTF-8&oe=UTF-8&otf=1&pc=1&ssel=0&tsel=0&kc=2&tk=" + myTk + "&q=" + content;

总结: 现在google 翻译都收费了,找免费的不容易啊,还好有一个网页版免费的, 通过使用爬虫, 爬取必要信息,收集数据.

superagent: 这个方法很好用, 爬虫慢慢搞!!!!!

使用这个方法, 能爬取大部分资源,是做爬虫的好帮手,解决了资源不足的问题,觉的内容好,使用多线程,百万级资源分分钟搞定!

使用被人的接口,怕被禁,网速不好会有延迟,影响体验.

自己做一个接口放网上,想怎么用就怎么用.就是这么任性.

不会弄的联系我,方式你懂的.......
