刚获取的tocken就过期 - WXOPEN Club | 微信小程序专业社区

刚获取tocken，然后拿去获取小程序码，返回结果总是提示tocken过期了。代码如下：

@Test

public void httpTest(){

String url = "https://api.weixin.qq.com/cgi-bin/token";

String params ="grant_type=client_credential&appid="+ appId +"&secret=" + secret;

String result = HttpRequest.sendGet(url,params);

System.out.println("---->");

String tocken = result.toLowerCase();

String Codeurl = "https://api.weixin.qq.com/cgi-bin/wxaapp/createwxaqrcode?access_token=" + tocken;

String codeParms =

"page=/index/index&width=200&scene=1&is_hyaline=false&auto_color=false&line_color={“r”:”0”,”g”:”0”,”b”:”0”}"

;

String codeRes = HttpRequest.sendPost(Codeurl, codeParms);

System.out.println("获取二维码成功！");

System.out.println(codeRes);

}

返回结果如下：

{"errcode":40001,"errmsg":"invalid credential, access_token is invalid or not latest hint: [2YYoSa06932862!]"}

请问有没有人遇到过这种问题啊？在线等，急急急！
