HTTP协议网络读卡器通讯报文

本说明使用的读卡器：https://item.taobao.com/item.htm?spm=a21dvs.23580594.0.0.52de2c1bGBhMtE&ft=t&id=22173428704

一、读卡器设置为GET方式提交刷卡数据

GET /IC-14h.asp?info=37&jihao=0&cardtype=5&card=0000000A&dn=169850547BD05F21 HTTP/1.1
Host: 192.168.1.211:5000
Connection: close
User-Agent: Mozilla/4.0
Accept-Language: en

二、读卡器设置为POST方式提交刷卡数据

POST /IC-14h.asp HTTP/1.1
Host: 192.168.1.211:5000
Connection: close
User-Agent: Mozilla/4.0
Accept-Language: en
Content-Type: application/x-www-form-urlencoded
Content-Length: 60

info=37&jihao=0&cardtype=5&card=0000000A&dn=169850547BD05F21

三、读卡器设置为JSON方式提交刷卡数据

POST /IC-14h.asp HTTP/1.1
Host: 192.168.1.211:5000
Connection: close
User-Agent: Mozilla/4.0
Accept-Language: en
Content-Type: application/json
Content-Length: 82

{"info":"24","jihao":"0","cardtype":"5","card":"0000000A","dn":"169850547BD05F21"}

四、服务器端以JSON方式回应驱动读卡器显示文字、播报语音

{"Response":"json","infotype":"1","info":"28","disp":"{卡号:}1234567890AB25-04-30 11:30:50","dispdelay":"20","beeptype":"1","voicetype":"读取卡号[n1]1234567890ABCDEF","k1delay":"20","k2delay":"20"}

五、服务器端以字符串方式回应驱动读卡器显示文字、播报语音

Response=1,32,{卡号:}1234567890AB25-04-30 11:30:50,20,2,读取卡号[n1]1234567890ABCDEF,20,30

六、服务端ASHX网页获取刷卡数据及回应示例
