font-size: 16px;"><strong><span style="line-height: 1.8; color: rgb(128, 0, 0);">一、简介</span></strong></span></p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif; line-height: 25.2px;">上一篇文章介绍了<a title="微信公众平台天气预报功能开发" href="http://www.cnblogs.com/mchina/p/3170551.html" target="_blank" style="text-decoration: none; color: rgb(0, 0, 0); border-bottom-width: 1px; border-bottom-style: dotted; border-bottom-color: rgb(51, 51, 51);">微信公众平台天气预报</a>功能的开发,实现了微信公众平台的第一个实际应用,在接下来的这一篇文章中,我们将对微信翻译功能进行简单开发,以供读者参考。</p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif; line-height: 25.2px;"><span style="line-height: 1.8; color: rgb(128, 0, 0); font-size: 16px;"><strong>二、思路分析</strong></span></p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif; line-height: 25.2px;"><span style="line-height: 1.8;">和上一篇查询天气的思路差不多,首先要对用户发送过来的消息进行判断,判断消息里是否含有“翻译”关键字,如果含有,则提取待翻译内容,然后调用网络上</span><span style="line-height: 1.8;">开放的翻译API 进行相关翻译。</span></p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif; line-height: 25.2px;"><span style="line-height: 1.8; font-size: 16px;"><strong><span style="line-height: 1.8; color: rgb(128, 0, 0);">三、翻译API 分析</span></strong></span></p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif; line-height: 25.2px;">网络上有很多翻译API,大家可以根据自己的需求进行选择。这里我们选择应用比较广泛的,翻译功能还比较不错的有道翻译API 和百度翻译API,下面对这两种API的相关信息进行分析。</p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif; line-height: 25.2px;"><strong>3.1 有道翻译API</strong></p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif; line-height: 25.2px;">3.1.1 API 地址:<a href="http://fanyi.youdao.com/openapi" style="text-decoration: none; color: rgb(0, 0, 0); border-bottom-width: 1px; border-bottom-style: dotted; border-bottom-color: rgb(51, 51, 51);">http://fanyi.youdao.com/openapi</a></p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif; line-height: 25.2px;"><strong>注意:</strong>有道提供的API 接口,在下面的测试时,json 数据格式返回不正确,到网上查阅资料,可以正确翻译的地址为&nbsp;<a href="http://fanyi.youdao.com/fanyiapi" target="_blank" style="text-decoration: none;
