明明時剛獲取的tocken，然后直接拿去獲取小程序碼，返回結(jié)果顯示tocken已經(jīng)過期。代碼如下：    @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("獲取二維碼成功！");        System.out.println(codeRes);            }然后返回結(jié)果時這樣的：{"errcode":40001,"errmsg":"invalid credential, access_token is invalid or not latest hint: [ZrecEa05114689!]"}不知小伙伴們有沒有遇到過這樣的問題的。求大神能否幫我解決一下啊！在線等！
