《糖果唱》-开发一个微信公共平台后台
开发一个公共账号的大体的开发思路是：
数据库相关的代码并没有给出，其实很简单的逻辑，大约用了一下午写完的，本来可以做的更加复杂的，为了快速实现就简化了，
1用户关注，返回一条默认信息 “欢迎挑战糖果唱音乐机器人，来感受不一样的音乐吧,开始请按1~”
PS：此时用户不管按什么，除了1之外都返回该信息，按9看团队联系方式等
2用户按1，返回一条音频信息，同时创建一条用户信息，信息存储用户得分，用户openid，答对和打错的数目
3，用户看到一条音频信息，如 ：“客官，俺已经为您准备好了一条上好的狼嚎，请您享用,猜一猜这首狼嚎的名字，1XXXX,2，XXX,3,XXXX4，XXX”，此处可准备多种这样的文字，可以编辑文字，如不输入1234则提示用户输入
4用户输入答案，此处判断答案是否正确，如正确则提示加分，也可输入0查询当前分值，输入9继续游戏
一、创建相应的数据表：
DROP TABLE IF EXISTS `wx_info`;
CREATE TABLE `wx_info` (
`openid` varchar(64) NOT NULL,
`point` int(11) unsigned zerofill DEFAULT NULL,
`answer` int(11) DEFAULT NULL,
`createtime` int(11) DEFAULT NULL,
PRIMARY KEY (`openid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;二、验证服务器TOKEN
详细的请参考 http://mp.weixin.qq.com/wiki/index.php?title=%E8%8E%B7%E5%8F%96access_token
三、编写相应的逻辑代码：
valid();
$wechatObj->responseMsg();
class wechatCallbackapiTest
{
public function valid()
{
$echoStr = $_GET["echostr"];
//valid signature , option
if($this->checkSignature()){
echo $echoStr;
exit;
}
}
public function responseMsg()
{
$textTpl = "
%s
0
";
$newsTpl = "
%s
%s
-
<![CDATA[%s]]>
1
";
$musicTpl = "
%s
<![CDATA[%s]]>
0
";
//get post data, May be due to the different environments
$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
//extract post data
if (!empty($postStr)){
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
//发送方ID
$fromUsername = $postObj->FromUserName;
//咱们的ID
$toUsername = $postObj->ToUserName;
$keyword = trim($postObj->Content);
