QQ云输入法调用说明
1.获取一个 key
URL: http://ime.qq.com/fcgi-bin/getkey?cb=PIME.keyback 将返回如下内容:
参数说明:
cb=PIME.keyback 回调函数名

返回内容:
PIME.keyback({"key":"9850f1051db25a1528883048c58cbe0c","ret":"suc"})

key 用于以后的输入法请求中
ret suc,成功

2.利用开放接口解析输入
URL(五笔输入法): http://ime.qq.com/fcgi-bin/gwb?key=9850f1051db25a1528883048c58cbe0c&cb=window.QQWebIME.callback885&q=w&p=1&pg=5 参数说明:
key 之前获取到的key
cb  回调函数
q   查询的字符串
p   当前为查询字符口串的第几页候选字,可不设置，默认为1
pg  每页显示多少候选字,可不设置,默认为5,且仅支持 5、9 两个值,其他值按5处理

返回内容:
window.QQWebIME.callback885({"is_end":"0","md":"1","p":"1","pg":"5","q":"w","ret":"suc","rs":["人","八","但","你","从","个","会","他","他们","公司"],"rsc":["","","jg","q","w","h","f","b","bwu","cng"],"rscnt":"10"})

is_end    是否为最后一页
md    (只有五笔输入法有些值返回,md=1,表示是使用五笔输入法?)
p    第几页(同请求中的参数)
pg    一页应该显示多少个候选字(同请求中的参数)
q    查询的字符串(同请求中的参数)
ret    suc,成功
rs    返回的候选字列表,如果pg为5,该值一般会是10,如果pg为9,该值一般为9
rsc    对应 rs 中要输出某个候选字还应输入的字符(如:要直接输出"但",对比发现你还应该输入jg(五笔输入法))
rscnt    返回的rs的数量

URL(拼音输入法): http://ime.qq.com/fcgi-bin/getword?key=9850f1051db25a1528883048c58cbe0c&cb=window.QQWebIME.callback885&q=c 参数说明:
同五笔输入法
返回内容:
window.QQWebIME.callback885({"is_end":"0","p":"1","pg":"5","q":"c","ret":"suc","rs":["才","错","次","从","草","菜","猜","擦","踩","惨","存","村","操","此","词","层","催","藏","凑","粗"],"rscnt":"20","rsn":["1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1"]})
