springboot的微信公众号（三）微信接入验证
首先pom依赖，你可以直接全部复制进去

application.properties配置文件
server.port = 8080
server.context-path = /wx-demo
spring.datasource.druid=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/wxtest
spring.datasource.username=root
spring.datasource.password=123456这里的数据库配置暂时没有用，可以先放着，如果你想接入数据库，可以直接接入
启动类
package com.example.weixin.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class WxDemoApplication {
public static void main(String[] args) {
SpringApplication.run(WxDemoApplication.class, args);
}
}
注意：如果配置了数据库文件，需要在建立相应的数据库，否则会报错
这个时候应该能正常启动了。
下面进行接入：
官方文档上面指出，需要四个参数，然后是get请求，参数需要加密的
接入代码如下：
@RequestMapping(value="/wx",method={RequestMethod.GET,RequestMethod.POST})
public void wxLogin(HttpServletRequest request,HttpServletResponse response) throws UnsupportedEncodingException{
//设置编码，不然接收到的消息乱码
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
String signature = request.getParameter("signature");//微信加密签名
String timestamp = request.getParameter("timestamp");//时间戳
String nonce = request.getParameter("nonce");//随机数
String echostr = request.getParameter("echostr");//随机字符串
PrintWriter out = null;
//接入验证
if(WeiXinUtil.checkSignature(signature, timestamp, nonce)){
if (echostr!=null) {
System.out.println(echostr);
try {
out = response.getWriter();
} catch (IOException e) {
e.printStackTrace();
}
out.write(echostr);//验证成功返回的值
return;
}校验代码
/**
*
* @param signature 微信加密签名
* @param timestamp 时间戳
* @param nonce 随机数
* @return
*/
public static boolean checkSignature(String signature,String timestamp,String nonce){
String[] str = new String[]{token,timestamp,nonce};
//排序
Arrays.sort(str);
//拼接字符串
StringBuffer buffer = new StringBuffer();
for(int i =0 ;i<str.length;i++){
buffer.append(str[i]);
}
//进行sha1加密
String temp = SHA1.encode(buffer.toString());
//与微信提供的signature进行匹对
return signature.equals(temp);
}private static final String token = "mytoken123456";//自己在微信测试平台设置的token加密比对代码
/**
* sha1加密
* @author Administrator
*
*/
public final class SHA1 {
private static final char[] HEX_DIGITS = {'0', '1', '2', '3', '4', '5',
'6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'};
/**
* Takes the raw bytes from the digest and formats them correct.
*
* @param bytes the raw bytes from the digest.
* @return the formatted bytes.
*/
private static String getFormattedText(byte[] bytes) {
int len = bytes.length;
StringBuilder buf = new StringBuilder(len * 2);
// 把密文转换成十六进制的字符串形式
for (int j = 0; j < len; j++) {
buf.append(HEX_DIGITS[(bytes[j] >> 4) & 0x0f]);
buf.append(HEX_DIGITS[bytes[j] & 0x0f]);
}
return buf.toString();
}
public static String encode(String str) {
if (str == null) {
return null;
}
try {
MessageDigest messageDigest = MessageDigest.getInstance("SHA1");
messageDigest.update(str.getBytes());
return getFormattedText(messageDigest.digest());
} catch (Exception e) {
throw new RuntimeException(e);
}
} 如果，校验成功就会在这里
弹出配置成功
同时，这里
也会显示成功的，一般不会失败，如果失败就慢慢排查。
