WP8.1小梦词典开发1:金山词霸API使用

原文出自：http://www.bcmeng.com/windows-phone-api/

今天开始小梦给大家分享一下小梦词典开发中几个关键问题,首先我们来看查词功能的实现.小梦词典的查词功能是通过金山词霸的查词API来实现的.首先我们需要申请金山词霸API的key:

金山词霸API的key申请:

申请地址:http://open.iciba.com/?c=api#jhjy   进入后输入您的网站名,网站地址和你的邮箱就可以,key会发送到你的邮箱里.我试过了,网站名和网站地址可以随意填写,只要邮箱是你的就可以.

金山词霸查词API数据返回格式:
