3.2、将微信公众号配置写入yaml文件并引入类中
wechat:
mpAppId: 你的微信测试号appId
mpAppSecret: 你的微信测试号secret
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
/**
* @author ：小肖
* @date ：Created in 2022/2/2 10:31
*/
@Component
@Data
@ConfigurationProperties(prefix = "wechat")
public class WechatAccountConfig {
/**
* 公众号id
*/
private String mpAppId;
/**
* 公众号密钥
*/
private String mpAppSecret;
}
3.3、编写配置类初始化设置wxMpService配置
import me.chanjar.weixin.mp.api.WxMpConfigStorage;
import me.chanjar.weixin.mp.api.WxMpInMemoryConfigStorage;
import me.chanjar.weixin.mp.api.WxMpService;
import me.chanjar.weixin.mp.api.impl.WxMpServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;
/**
* @author ：小肖
* @date ：Created in 2022/2/2 10:24
*/
@Component
public class WechatMpConfig {
@Autowired
private WechatAccountConfig wechatAccountConfig;
@Autowired
private WxMpInMemoryConfigStorage wxMpInMemoryConfigStorage;
@Bean
public WxMpService wxMpService(){
WxMpService wxMpService = new WxMpServiceImpl();
wxMpService.setWxMpConfigStorage(wxMpInMemoryConfigStorage);
return wxMpService;
}
@Bean
public WxMpInMemoryConfigStorage wxMpConfigStorage(){
/**
* 这里需要注意的是 由于父类中没有定义对应的接口
* 所以所有的方法都在其实现类中，所以我们要构造实现类
*/
WxMpInMemoryConfigStorage wxMpConfigStorage = new WxMpInMemoryConfigStorage();
wxMpConfigStorage.setAppId(wechatAccountConfig.getMpAppId());
wxMpConfigStorage.setSecret(wechatAccountConfig.getMpAppSecret());
return wxMpConfigStorage;
}
}
3.4、编写对应的controller
import com.xiao.enums.ResultEnum;
import com.xiao.exception.SellException;
import lombok.extern.slf4j.Slf4j;
import me.chanjar.weixin.common.api.WxConsts;
import me.chanjar.weixin.common.error.WxErrorException;
import me.chanjar.weixin.mp.api.WxMpService;
import me.chanjar.weixin.mp.bean.result.WxMpOAuth2AccessToken;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
/**
* @author ：小肖
* @date ：Created in 2022/2/2 10:20
*/
@Controller
@RequestMapping("/wechat")
@Slf4j
public class WechatController {
@Autowired
private WxMpService wxMpService;
@GetMapping("/authorize")
public String authorize(@RequestParam("returnUrl") String returnUrl){
String url = "http://xiao-sell.natapp1.cc/sell/wechat/userInfo";
String redirectUrl = wxMpService.oauth2buildAuthorizationUrl(url, WxConsts.OAuth2Scope.SNSAPI_USERINFO,returnUrl);
return "redirect:" + redirectUrl;
}
@GetMapping("/userInfo")
public String userInfo(@RequestParam("code") String code,
@RequestParam("state") String returnUrl) {
WxMpOAuth2AccessToken wxMpOAuth2AccessToken = new WxMpOAuth2AccessToken();
try{
wxMpOAuth2AccessToken = wxMpService.oauth2getAccessToken(code);
}catch (WxErrorException e){
log.error("【微信网页授权错误】 exception = {}",e);
throw new SellException(ResultEnum.WECHAT_MP_ERROR.getCode(),e.getError().getErrorMsg());
}
String openId = wxMpOAuth2AccessToken.getOpenId();
log.info("openid = {}",openId);
return "redirect:" + returnUrl + "?openid=" + openId;
}
}
3.5、进行debug测试
第一个断点
该重定向的url很明显就是我们手工方式中获取code的url。
第二个断点
成功获取了code和openid。
