"errcode":40163,"errmsg":"code been used

[876529270]

刚刚接触 微信开发 被这个40163 困扰好多天了,心态崩了,求大神解决.直接上代码
用的是微信测试号开发,ngrok映射工具
现在的问题是
第一个用户可以顺利获取到openid,后面的用户就获取不到了
,每一次生成的code也是新的,但就是没有用,心态爆炸
拦截器代码

private static final String APPID = "??";
	private static final String SCOPE = "snsapi_base";
	private static String REDIRECT_URI = "https://b3d6bc4a.ngrok.io/WeChat/getOpenid.do";
	private static String URL = "https://open.weixin.qq.com/connect/oauth2/authorize?appid=APPID&redirect_uri=REDIRECT_URI&response_type=code&scope=SCOPE&state=STATE#wechat_redirect";

	@Override
	public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
			throws Exception {
		HttpSession session = request.getSession();
		String openid = (String) request.getSession().getAttribute("openid");
		if (openid == null) {
			REDIRECT_URI = UrlUtil.getURLEncoderString(REDIRECT_URI);
			URL = URL.replace("APPID", APPID).replace("REDIRECT_URI", REDIRECT_URI).replace("SCOPE", SCOPE);
			session.setAttribute("reqPath", request.getServletPath());
			response.sendRedirect(URL);
			session.setAttribute("URL", URL);
			return false;
		} else {
			return true;
		}
	}

获取openid代码

private static final String APPID = "??";
	private static final String SECRET = "??";
	private static String requestUrl = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=APPID&secret=SECRET&code=CODE&grant_type=authorization_code";

	@RequestMapping("/getOpenid")
	public String getOpenid(HttpServletRequest request, HttpServletResponse response) {
		String path = (String) request.getSession().getAttribute("reqPath");
		
		// 用户同意授权后，能获取到code
		String code = request.getParameter("code");
		
		// 获取网页授权access_token
		JSONObject object = getOauth2AccessToken(APPID, SECRET, code);
		
		request.getSession().setAttribute("openid", object.getString("openid"));
		return "redirect:" + path;

	}

	public static JSONObject getOauth2AccessToken(String appId, String appSecret, String code) {
		// 拼接请求地址
		requestUrl = requestUrl.replace("APPID", appId).replace("SECRET", appSecret).replace("CODE", code);
		// 获取网页授权凭证
		JSONObject jsonObject = null;

		try {
			jsonObject = HttpUtil.getJsonForGet(requestUrl);
		} catch (ParseException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}

		return jsonObject;
	}

沙发!!!!

终于解决了,是静态方法的问题,静态方法只会初始化一次,后面再调用传参数,code值也改变不了

private static final String APPID = "??";
    private static final String SECRET = "??";
    private  String requestUrl = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=APPID&secret=SECRET&code=CODE&grant_type=authorization_code";
 
    @RequestMapping("/getOpenid")
    public String getOpenid(HttpServletRequest request, HttpServletResponse response) {
        String path = (String) request.getSession().getAttribute("reqPath");
         
        // 用户同意授权后，能获取到code
        String code = request.getParameter("code");
         
        // 获取网页授权access_token
        JSONObject object = getOauth2AccessToken(APPID, SECRET, code);
         
        request.getSession().setAttribute("openid", object.getString("openid"));
        return "redirect:" + path;
 
    }
 
    public  JSONObject getOauth2AccessToken(String appId, String appSecret, String code) {
        // 拼接请求地址
        requestUrl = requestUrl.replace("APPID", appId).replace("SECRET", appSecret).replace("CODE", code);
        // 获取网页授权凭证
        JSONObject jsonObject = null;
 
        try {
            jsonObject = HttpUtil.getJsonForGet(requestUrl);
        } catch (ParseException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
 
        return jsonObject;
    }

自己给自己埋坑

分享网页的时候，带了一个code，这个如何解决啊

大哥，教教我

[mianguiwu2107]

public class OAuthServlet extends HttpServlet { private static final long serialVersionUID = -1847238807216447030L; public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { request.setCharacterEncoding( request.setCharacterEncoding("utf-8"); response.setCharacterEncoding("utf-8"); // 用户同意授权后，能获取到code String code = request.getParameter("code"); String state = request.getParameter("state"); // 用户同意授权 if (!"authdeny".equals(code)) { // 获取网页授权access_token WeixinOauth2Token weixinOauth2Token = AdvancedUtil.getOauth2AccessToken("wxe34a90ac7bxxcab85c", "1207d566090a8344xxxd6224c02c", code); // 网页授权接口访问凭证 String accessToken = weixinOauth2Token.getAccessToken(); // 用户标识 String openId = weixinOauth2Token.getOpenId(); // 获取用户信息 SNSUserInfo snsUserInfo = AdvancedUtil.getSNSUserInfo(accessToken, openId); // 设置要传递的参数 request.setAttribute("snsUserInfo", snsUserInfo); request.setAttribute("state", state); } // 跳转到index.jsp request.getRequestDispatcher("index.jsp").forward(request, response); } } 第一次可以获取到信息，但是第二次就code已被使用 大哥，求教一下怎么改才能让code不被重复使用，具体代码有吗

这个和静态方法没什么关系吧，只是楼主讲链接设置成了全局变量，第一次请求对链接进行了修改并保存了下来，第二次请求来是对修改之后的链接进行替换，当然无法匹配到要修改的字符串，所以访问的还是第一次访问的链接，才会出现这样的错误
