1.认证服务器，使公众号开发后可以调用该服务器的下的接口（js同）
在这里插入图片描述

@RestController
public class WeixinController {
    private Logger logger = LoggerFactory.getLogger(WeixinController.class);

    @GetMapping("")//(value = "/",produces = { "application/json;charset=utf-8" })//
    public String getWxRequest(@RequestParam(required = false) String echostr,
                               @RequestParam(required = false) String signature,
                               @RequestParam(required = false) String timestamp,
                               @RequestParam(required =false) String nonce){
        String token="weixin";
        //1）将token、timestamp、nonce三个参数进行字典序排序
        List<String> list=new ArrayList();
        list.add(token);
        list.add(timestamp);
        list.add(nonce);
        Collections.sort(list);
        //2）将三个参数字符串拼接成一个字符串进行sha1加密
        String sha1Hex = DigestUtils.sha1Hex(list.get(0) + list.get(1) + list.get(2));
        logger.info("sha1Hex:{}",sha1Hex);
        //将加密与signature比对，结果一致说明来自微信服务器，返回echostr
        if (sha1Hex.equals(signature)){
            return echostr;
        }
        return null;
    }
}

js直接配置就可以

设置授权的网站

在这里插入图片描述

先开发自定义菜单模块，设置网页入口，然后进入网页开发(授权只是为了获取用户信息等)
在这里插入图片描述

2.获取用户access_token

String url=" https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=%s&secret=%s";
        url= String.format(url,"wxd51c370ef340ace1","a47f52d802dca90063816c64b2f59aca");
        //application/x-www-form-urlencoded
        Connection.Response response = Jsoup.connect(url)
                .ignoreContentType(true)
                .header("Accept", "application/json, text/plain, */*")
                // .header("Content-Type", "application/json;charset=UTF-8")
                .method(Connection.Method.GET).execute();
        String body = response.body();
        JSONObject jsonObject = JSONObject.parseObject(body);
        System.out.println(jsonObject);

=======微信网页开发

3.通过oauth2授权获取登录令牌access_token(不同于用户access_token)

/*通过这个页面授权*/
    @GetMapping("/oauth")
    public void oauth(HttpServletResponse response) throws IOException {
        //配置域名不带http或者https===》shaofeng.free.idcfengye.com (~~~挂载域名后面的都可以授权）
        //获取code
        String url="https://open.weixin.qq.com/connect/oauth2/authorize?" +
                "appid=%s" +
                "&redirect_uri=%s" +
                "&response_type=code&scope=snsapi_userinfo&state=STATE#wechat_redirect";
        url= String.format(url,"wxd51c370ef340ace1","http://shaofeng.free.idcfengye.com/getUserInfo");
        //url是上面配置的授权url域名下的
        //用户确认授权跳转到redirect_uri
        response.sendRedirect(url);

    }

    @GetMapping("/getUserInfo")
    public String getUserInfo(HttpServletRequest request) throws IOException{
        String code = request.getParameter("code");
        String url1="https://api.weixin.qq.com/sns/oauth2/access_token?appid=%s&secret=%s&code=%s&grant_type=authorization_code";
        url1= String.format(url1,"wxd51c370ef340ace1","a47f52d802dca90063816c64b2f59aca",code);

        Connection.Response response1 = Jsoup.connect(url1)
                .ignoreContentType(true)
                .header("Accept", "application/json, text/plain, */*")
                // .header("Content-Type", "application/json;charset=UTF-8")
                .method(Connection.Method.POST).execute();

        System.out.println(JSONObject.parseObject(response1.body()));
        return JSONObject.parseObject(response1.body()).getString("access_token");

    }
