微信公众号（答题抽奖）开发

标签 微信 公众号 答题 抽奖 开发 繁體版
原文   原文链接

首先在公众号里面设置好连接地址。javascript

接下来开始开发：css

连接地址的页面，也就是首页，须要调微信接口获取code:html

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>话费抽奖</title>
</head>
<body onLoad="parent.location='https://open.weixin.qq.com/connect/oauth2/authorize?appid=*****************&redirect_uri=http://survey.runmin.top/uploa/wx.do&response_type=code&scope=snsapi_base'">
</body>
</html>

注意这里的redirect_uri就是跳转的地址，而且微信会带着code返回，也就是说request中有code参数。java

注意我这里web.xml里面配置了多个servlet，包括wx.do:mysql

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

    <servlet-class>com.bt.action.Wx</servlet-class>

    <url-pattern>/wx.do</url-pattern>

  </servlet>
  <servlet-mapping>
    <servlet-name>UserScore</servlet-name>
    <url-pattern>/UserScore.do</url-pattern>
  </servlet-mapping>
  <servlet>
    <servlet-name>UserPrize</servlet-name>
    <servlet-class>com.bt.action.UserPrize</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>UserPrize</servlet-name>
    <url-pattern>/UserPrize.do</url-pattern>
  </servlet-mapping>
    <servlet>
    <servlet-name>GetPercent</servlet-name>
    <servlet-class>com.bt.action.GetPercent</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>GetPercent</servlet-name>
    <url-pattern>/GetPercent.do</url-pattern>
  </servlet-mapping>
      <servlet>
    <servlet-name>GetPrice</servlet-name>
    <servlet-class>com.bt.action.GetPrice</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>GetPrice</servlet-name>
    <url-pattern>/GetPrice.do</url-pattern>
  </servlet-mapping>

  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

因此调完微信之后会跳转到个人com.bt.action.Wx这个servlet（乱码没有作处理，比较麻烦）：jquery
