网站建设服务标准化公司如何注册企业邮箱

很多系统中需要做自己的翻译器,所以大家都想到把现成的网站扒下来用,Google Translate和Yahoo Babel Fish就成了大家的首选.Google好说,直接用HttpURLConnection做post请求即可,但是Google防盗措施非常好,用个几次就出现一个防盗链的页面,就无法玩了,所以Yahoo Babel Fish就成了大家的选择.但是发现最新版本的宝贝鱼用HttpURLConnection怎么请求,怎么设置编码方式得到的中文都是乱码.后来发现,在java中必须设置connection.setRequestProperty( "User-agent" , "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.1.4322; .NET CLR 2.0.50215; fqSpider)" );才能得到正确的中文显示,c#中同样.还需要注意的是,在输入的link中是中文的话,除了用java.net.URLEncoder.encode编码外还需要在link中加入&ei=gb2312.下面是全部编码.
