微信小程序的消息推送的token的配置

女爷i 2023-01-08 05:24 191阅读 0赞

在做小程序的一个功能的时候 我们需要用到消息推送  
服务器ip,域名什么的都配置好了,但示token就是报错  
下面的代码复制带走 修改一下配置就可以了,(大部分也是百度的,在这里做个笔记整合一下)

上图红线部分后面的地方就是我们验证token的接口路径

package org.begete.zhongkehaobo.demos.controller;

    @RestController

    public class WXTokenController {
        
        @RequestMapping("/verify_wx_token")
        public String verifyWXToken(HttpServletRequest request) throws AesException {
        
            String msgSignature = request.getParameter("signature");
            String msgTimestamp = request.getParameter("timestamp");
            String msgNonce = request.getParameter("nonce");
            String echostr = request.getParameter("echostr");
            if (WXPublicUtils.verifyUrl(msgSignature, msgTimestamp, msgNonce)) {
        
                return echostr;
            }
            return null;
        }
    
    }

            String signature = SHA1.getSHA1("123456", timeStamp, nonce);
            if (!signature.equals(msgSignature)) {

            }
            return true;

    }

加密

        public static String getSHA1(String token, String timestamp, String nonce) throws AesException {
        
            try {
        
                String[] array = new String[]{
        token, timestamp, nonce};
                StringBuffer sb = new StringBuffer();
                // 字符串排序
                Arrays.sort(array);
                for (int i = 0; i < 3; i++) {
        
                    sb.append(array[i]);
                }
                String str = sb.toString();

                    if (shaHex.length() < 2) {
