微信域名回调
标签(空格分隔): springboot java wechat
普通方法
- 设置域名(内网穿透工具natapp)
需要在微信中设置回调域名
- 获取code
经过发送 微信服务器,微信重定向到本地。
https://open.weixin.qq.com/connect/oauth2/authorize?appid=APPID&redirect_uri=REDIRECT_URI&response_type=code&scope=SCOPE&state=STATE#wechat_redirect
APPID = 对接公众号账户id
REDIRECT_URI = 回调域名地址
SCOPE = 获取用户信息方式两种(snsapi_base、snsapi_userinfo)
- 换取access_token
通过重定向获取code,重新发送请求获取用户信息。
https://api.weixin.qq.com/sns/oauth2/access_token?appid=APPID&secret=SECRET&code=CODE&grant_type=authorization_code
APPID = 对接公众号账户id
SECRET = 对接公众号账户secret
CODE = 重定向获取的id
/**
* 获取code测试
* @param code
*/
@GetMapping("/auth")
public void auth(@RequestParam("code") String code){
log.info("code={}",code);
String url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=APPID&secret=SECRET&code="+code+"&grant_type=authorization_code";
RestTemplate restTemplate = new RestTemplate();
String response = restTemplate.getForObject(url,String.class);
log.info("response={}",response);
}
使用SDK方法
- 引用
<dependency>
<groupId>com.github.binarywang</groupId>
<artifactId>weixin-java-mp</artifactId>
<version>2.8.0</version>
</dependency>
- 获取code
//引用配置参数
@Data
@Component
@ConfigurationProperties(prefix = "wechat")
public class WechatAccountConfig {
/** 账户 .*/
private String wechat_appid;
/** 密码 .*/
private String wechat_secret;
}
//参数设置
@Component
public class WechatMpConfig {
@Autowired
private WechatAccountConfig wechatAccountConfig;
@Bean
public WxMpService wxMpService(){
WxMpService wxMpService = new WxMpServiceImpl();
wxMpService.setWxMpConfigStorage(wxMpConfigStorage());
return wxMpService;
}
@Bean
public WxMpConfigStorage wxMpConfigStorage(){
WxMpInMemoryConfigStorage wxMpConfigStorage = new WxMpInMemoryConfigStorage();
wxMpConfigStorage.setAppId(wechatAccountConfig.getWechat_appid());
wxMpConfigStorage.setSecret(wechatAccountConfig.getWechat_secret());
return wxMpConfigStorage;
}
}
//获取code
/**
* 获取code
* @param returnUrl
* @return
*/
@GetMapping("/authrize")
public String authrize(@RequestParam("returnUrl") String returnUrl){
String url = "http://www.xiaojinzi.top/sell/wechat/userInfo";
String rediectUrl = wxMpService.oauth2buildAuthorizationUrl(url,WxConsts.OAUTH2_SCOPE_USER_INFO, URLEncoder.encode(returnUrl));
return "rediectUrl:" + rediectUrl;
}
- 获取openid
/**
* 微信openid
* @param code
* @param returnUrl
* @return
*/
@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】 e={}",e);
throw new SellException(ResultEnum.WECHAT_WEB_ERROR.getCode(),e.getError().getErrorMsg());
}
String openid = wxMpOAuth2AccessToken.getOpenId();
return "rediectUrl:"+ returnUrl + "?openid="+openid;
}
