JAVA调用微信token返回系统繁忙_微信授权登录用java获取code后再获取token出现40163，code bean used...

但是又没出错，我点击链接

https://open.weixin.qq.com/co...://39.108.80.19:8080/wxtest/callBackServlet&response_type=code&scope=snsapi_base&state=STATE#wechat_redirect

进入然后显示这样

然后再点击继续访问就去到回调页面中显示那段话40163。。。的

我的代码如下：

package servlet;

import Utils.AuthUtil;

import org.json.JSONObject;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

import java.io.PrintWriter;

/**

public class CallBackServlet extends HttpServlet {

/**

*

*/

private static final long serialVersionUID = 1L;

//private static int i = 0;

@Override

protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {

String code =req.getParameter("code");

String url="https://api.weixin.qq.com/sns/oauth2/access_token?appid=" + AuthUtil.APPID+

"&secret=" +AuthUtil.APPSECRET+

"&code=" +code+

"&grant_type=authorization_code";

JSONObject jsonObject= AuthUtil.doGetJson(url);

PrintWriter writer = resp.getWriter();

writer.print(jsonObject.toString()+"--666--"+code);

}

}

///

package Utils;

import org.apache.http.HttpEntity;

import org.apache.http.HttpResponse;

import org.apache.http.client.methods.HttpGet;

import org.apache.http.impl.client.DefaultHttpClient;

import org.apache.http.util.EntityUtils;

import org.json.JSONObject;

import java.io.IOException;

public class AuthUtil {

public static final String APPID="wx084fd8c55cc18287";

public static final String APPSECRET="335f95212c63591d2b3d4404424c9492";

public static JSONObject doGetJson(String url) throws IOException {

JSONObject jsonObject=null;

DefaultHttpClient defaultHttpClient=new DefaultHttpClient();

HttpGet httpGet=new HttpGet(url);

HttpResponse httpResponse = defaultHttpClient.execute(httpGet);

HttpEntity httpEntity=httpResponse.getEntity();

if(httpEntity!=null){

String result= EntityUtils.toString(httpEntity,"UTF-8");

jsonObject=new JSONObject(result);

//System.out.println("jsonObject: "+jsonObject);

}

httpGet.releaseConnection();

return jsonObject;

}

}

试了很多种方法都是提示这样
