企业微信第三方应用（三）基于springboot开发（获取Ticket，auth_code）

一、构建spring boot项目
1、新建项目
新建一个模块（module）：enterprise-wechat
新建一个子模块（module）：wechat
目录结构如下：

结构描述：
common
-> WeChatConstants：存放企业微信一些常量，公用参数
-> WeChatUtils：存放企业微信第三方应用api
controller
-> SystemController：控制层，接收请求
entity
-> aes：目录下文件企业微信加解密包
service
-> IConfigService：调用企业微信服务层
pom.xml
-> 导入所需要的jar包

pom.xml中需要导入commons.codec包

<dependency>
   <groupId>commons-codec</groupId>
   <artifactId>commons-codec</artifactId>
   <version>1.9</version>
</dependency>

2、方法描述
1）doGetCallback：
① 接收验证请求，用于验证通用开发参数系统事件接收URL、数据回调URL、指令回调URL。
② 企业微信后台录入回调URL点击保存时，微信服务器会立即发送一条GET请求到对应URL，该函数就对URL的signature进行验证。

2）doPostCallback：
① 用于获取 suite_ticket，安装应用时企业微信传递过来的auth_code：指令回调URL。
② 当刷新ticket传递【SuitID】：指令回调URL。
③ 当打开应用时传递【CorpID】：数据回调URL。

3、代码编写
1）企业微信配置类：WeChatConstants

package com.wechat.common;

/**

public class WeChatConstants {

    // 企业微信授权码获取时间
    public static final Long EXPIRES_IN = 24 * 60 * 60 * 1000L;

     */
    public static final String ENCODING_AES_KEY = "IESLPSyW4vyBB90jkzfwfYRtcMky6LIOevr4SVefz7I";

    public static final String REDIRECT_URI = "REDIRECT_URI";

    /**

     */
    public static final String REDIRECT_URL = "www.baidu.com";

    // 第三方应用id（即ww或wx开头的suite_id）
    public static final String APP_ID= "APPID";

    public static final String PERMANENT_CODE = "PERMANENT_CODE";

}

2）企业微信api：WeChatUtils

package com.wechat.common;

/**

 */
public class WeChatUtils {
    /**
     * 第三方应用api start
     */
    // 获取第三方应用凭证

3）controller层：SystemController

package com.wechat.controller;

import com.wechat.service.IConfigService;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.ServletInputStream;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.PrintWriter;

/**
 * 控制层
 */
@Slf4j
@RestController
@RequestMapping(value = "system")
public class SystemController {

    @Autowired
    private IConfigService configService;

    /**
     * 验证通用开发参数及应用回调
     * @param: request
     * @param: response
     * @returns: void
     */
    @ApiOperation(value = "验证通用开发参数及应用回调")
    @GetMapping(value = "getEchostr")
    public void doGetCallback(HttpServletRequest request, HttpServletResponse response) throws Exception {
        // 微信加密签名
        String msgSignature = request.getParameter("msg_signature");
        // 时间戳
        String timestamp = request.getParameter("timestamp");
        // 随机数
        String nonce = request.getParameter("nonce");
        // 随机字符串
        // 如果是刷新，需返回原echostr
        String echoStr = request.getParameter("echostr");
        String sEchoStr=  "";
        PrintWriter out;
        log.debug("msgSignature: " + msgSignature+"timestamp="+timestamp+"nonce="+nonce+"echoStr="+echoStr);
        try {
            sEchoStr = configService.doGetCallback(msgSignature,timestamp,nonce,echoStr); //需要返回的明文;
            log.debug("doGetCallback-> echostr: " + sEchoStr);
            // 验证URL成功，将sEchoStr返回
            out = response.getWriter();
            out.print(sEchoStr);
        } catch (Exception e) {
            //验证URL失败，错误原因请查看异常
            e.printStackTrace();
        }
    }

    /**
     * 刷新ticket，AuthCode
     */
    @ApiOperation(value = "刷新ticket，AuthCode")
    @PostMapping(value = "getEchostr")
    public String doPostCallback(HttpServletRequest request) throws Exception {
        // 微信加密签名
        String msgSignature = request.getParameter("msg_signature");
        // 时间戳
        String timestamp = request.getParameter("timestamp");
        // 随机数
        String nonce = request.getParameter("nonce");
        // 类型
        String type = request.getParameter("type");

        String success = configService.doPostCallback(msgSignature, timestamp, nonce, type, corpId, in);
        return success;
    }
}

4）Service层：IConfigService

package com.wechat.service;

import javax.servlet.ServletInputStream;

/**

 */
public interface IConfigService {

    /**
     * 验证通用开发参数及应用回调
     * @returns: java.lang.String
     */
    String doGetCallback(String msgSignature, String timestamp, String nonce, String echoStr);

    /**
     * 获取SuiteTicket，AuthCode
     */
    String doPostCallback(String msgSignature, String timestamp, String nonce, String type, String corpId, ServletInputStream in);
}

5）service实现类：ConfigServiceImpl

@Slf4j
@Service
public class ConfigServiceImpl implements IConfigService {

    @Autowired

     */
    @Override
    public String doGetCallback(String msgSignature, String timestamp, String nonce, String echoStr) {
        //需要返回的明文
        String sEchoStr="";
        try {
            log.debug(WeChatConstants.TOKENS, WeChatConstants.ENCODING_AES_KEY, WeChatConstants.CORP_ID);
            WXBizMsgCrypt wxcpt = new WXBizMsgCrypt(WeChatConstants.TOKENS, WeChatConstants.ENCODING_AES_KEY, WeChatConstants.CORP_ID);
            sEchoStr = wxcpt.VerifyURL(msgSignature, timestamp, nonce, echoStr);
        } catch (AesException e) {
            e.printStackTrace();
        }
        return sEchoStr;
    }

    /**

     */
    @Override
    public String doPostCallback(String msgSignature, String timestamp, String nonce, String type, String corpId, ServletInputStream in) {
        String id = "";
        // 访问应用和企业回调传不同的ID
        if(!StringUtils.isNull(type) && type.equals("data")){
            id = corpId;
            log.debug("======corpId==="+id);
        } else {

            }
            log.debug("====msg_signature===="+msgSignature+"====timestamp==="+timestamp+"====nonce==="+nonce+"====postData==="+postData);
            String suiteXml = wxcpt.DecryptMsg(msgSignature, timestamp, nonce, postData);
            log.debug("suiteXml: " + suiteXml);
            Map suiteMap = WxUtil.parseXml(suiteXml);
            log.debug("==suiteMap=="+ JSONUtils.toJSONString(suiteMap));
            if(suiteMap.get("SuiteTicket") != null) {
                String suiteTicket = (String) suiteMap.get("SuiteTicket");
                CacheData.put(WeChatConstants.SUITE_TICKET, suiteTicket);
                log.debug("====SuiteTicket=====" + suiteTicket);
            } else if(suiteMap.get("AuthCode") != null){
                String authCode = (String) suiteMap.get("AuthCode");
                log.debug("doPostValid->AuthCode:" + authCode);
                //根据authcode获取企业永久授权码
                weChatService.getPermanentCode(authCode);
                CacheData.put(WeChatConstants.AUTH_CODE, authCode);

            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return "success";
    }

4、验证
以上代码编写完成后，就可以打包到环境上面进行测试验证：
①：echostr验证

返回结果：返回 echostr，并显示已验证

16:11:46.940 [http-nio-9205-exec-7] INFO  c.q.w.s.c.SystemController - [doGetValid,94] - doGetCallback->echostr: 577115934236344259
16:11:46.969 [http-nio-9205-exec-3] INFO  c.q.w.s.c.SystemController - [doGetValid,94] - doGetCallback->echostr: 5267604771365158379

②：刷新Ticket：获取Ticket有两种方式，一是点击按钮获取，二是企业微信每15分钟会调用回调接口获取一次

点击“刷新Ticket” 会弹出如下图，然后点击确定

 Ticket 有效期为30分钟；建议把Ticket放到数据库或者redis中

 ③：获取auth_code
安装第三方应用的时候，会获取auth_code

 ④：安装测试流程

通过企业微信扫码进行安装
