JAVA 微信-基本验证

微信公众平台信息配置：

具体实现，废话不多说直接贴代码：

WeixinController:

package com.qianchong.weixin.controller;

import com.qianchong.weixin.utils.CheckUtil;
import com.qianchong.weixin.vo.WeixinCheckVo;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

/**
 * @description: 微信验证
 * @author: atom
 * @create: 2018-01-17 11:44
 **/
@RestController
@RequestMapping("weixin")
public class WeixinController {

    @RequestMapping("index")
    public void index(WeixinCheckVo weixinCheckVo, HttpServletResponse response) throws IOException {
        //通过检验signature对请求进行校验，若校验成功则原样返回echostr，表示接入成功，否则接入失败
        if (CheckUtil.checkSignature(weixinCheckVo.getSignature(), weixinCheckVo.getTimestamp(), weixinCheckVo.getNonce())) {
            response.getWriter().print(weixinCheckVo.getEchostr());
        }
    }

}

WeixinCheckVo:

package com.qianchong.weixin.vo;

/**
 * @author: atom
 * @create: 2018-01-18 09:18
 **/
public class WeixinCheckVo {

    /**
     * 微信加密签名
     */
    private String signature;

    /**
     * 时间戳
     */
    private String timestamp;

    /**
     * 随机数
     */
    private String nonce;

    /**
     * 随机字符串
     */
    private String echostr;

    public String getSignature() {
        return signature;
    }

    public void setSignature(String signature) {
        this.signature = signature;
    }

    public String getTimestamp() {
        return timestamp;
    }

    public void setTimestamp(String timestamp) {
        this.timestamp = timestamp;
    }

    public String getNonce() {
        return nonce;
    }

    public void setNonce(String nonce) {
        this.nonce = nonce;
    }

    public String getEchostr() {
        return echostr;
    }

    public void setEchostr(String echostr) {
        this.echostr = echostr;
    }
}

验证工具类，CheckUtils:

package com.qianchong.weixin.utils;

import org.apache.commons.lang3.StringUtils;

import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

/**
 * @description: 验证签名信息
 * @author: atom
 * @create: 2018-01-17 12:34
 **/
public class CheckUtil {

    /**
     * weixin绑定token信息
     */
    private static String token = "你的token";

    /**
     * 验证签名
     *
     * @param signature
     * @param timestamp
     * @param nonce
     * @return
     */
    public static boolean checkSignature(String signature, String timestamp, String nonce) {
        if(StringUtils.isBlank(signature) || StringUtils.isBlank(timestamp) || StringUtils.isBlank(nonce)){
            return false;
        }
        String[] arr = new String[] { token, timestamp, nonce };
        sort(arr);
        StringBuilder content = new StringBuilder();
        for (int i = 0; i < arr.length; i++) {
            content.append(arr[i]);
        }
        String tmpStr = null;
        try {
            MessageDigest md = MessageDigest.getInstance("SHA-1");
            byte[] digest = md.digest(content.toString().getBytes());
            tmpStr = byteToStr(digest);
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        }
        return tmpStr != null ? tmpStr.equals(signature.toUpperCase()) : false;
    }

    /**
     * 将字节数组转换为十六进制字符串
     *
     * @param byteArray
     * @return
     */
    private static String byteToStr(byte[] byteArray) {
        String strDigest = "";
        for (int i = 0; i < byteArray.length; i++) {
            strDigest += byteToHexStr(byteArray[i]);
        }
        return strDigest;
    }

    /**
     * 将字节转换为十六进制字符串
     *
     * @param mByte
     * @return
     */
    private static String byteToHexStr(byte mByte) {
        char[] Digit = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F' };
        char[] tempArr = new char[2];
        tempArr[0] = Digit[(mByte >>> 4) & 0X0F];
        tempArr[1] = Digit[mByte & 0X0F];
        String s = new String(tempArr);
        return s;
    }

    /**
     * 字典排序
     * @param array
     */
    public static void sort(String[] array) {
        for (int i = 0; i < array.length - 1; i++) {
            for (int j = i + 1; j < array.length; j++) {
                if (array[j].compareTo(array[i]) < 0) {
                    String temp = array[i];
                    array[i] = array[j];
                    array[j] = temp;
                }
            }
        }
    }
}
