微信请求发生错误！错误代码：40001，说明：invalid credential, access_token is invalid or not latest hints

首先检查AppSecret是否填写正确(然并卵)
检查获取access_token的接口是否混淆,一个是基础access_token,一个是网页授权access_token,其差别在于基础access_token无需code,所以使用要明确
如下:
1.如果使用以下接口获取用户信息则使用网页授权access_token,参数和返回数据说明请参考网页授权

http：GET（请使用https协议） https://api.weixin.qq.com/sns/userinfo?access_token=ACCESS_TOKEN&openid=OPENID&lang=zh_CN

正确则返回数据

{   
  "openid":" OPENID",
  "nickname": NICKNAME,
  "sex":"1",
  "province":"PROVINCE",
  "city":"CITY",
  "country":"COUNTRY",
  "headimgurl":       "http://thirdwx.qlogo.cn/mmopen/g3MonUZtNHkdmzicIlibx6iaFqAc56vxLSUfpb6n5WKSYVY0ChQKkiaJSgQ1dZuTOgvLLrhJbERQQ4eMsv84eavHiaiceqxibJxCfHe/46",
  "privilege":[ "PRIVILEGE1" "PRIVILEGE2"     ],
  "unionid": "o6_bmasdasdsad6_2sgVt7hMZOPfL"
}

2.如果使用以下接口获取用户信息则使用基础access_token,参数和返回数据说明请参考获取用户基本信息

http请求方式: GET https://api.weixin.qq.com/cgi-bin/user/info?access_token=ACCESS_TOKEN&openid=OPENID&lang=zh_CN

正确则返回数据

{
    "subscribe": 1, 
    "openid": "o6_bmjrPTlm6_2sgVt7hMZOPfL2M", 
    "nickname": "Band", 
    "sex": 1, 
    "language": "zh_CN", 
    "city": "广州", 
    "province": "广东", 
    "country": "中国", 
    "headimgurl":"http://thirdwx.qlogo.cn/mmopen/g3MonUZtNHkdmzicIlibx6iaFqAc56vxLSUfpb6n5WKSYVY0ChQKkiaJSgQ1dZuTOgvLLrhJbERQQ4eMsv84eavHiaiceqxibJxCfHe/0",
    "subscribe_time": 1382694957,
    "unionid": " o6_bmasdasdsad6_2sgVt7hMZOPfL"
    "remark": "",
    "groupid": 0,
    "tagid_list":[128,2],
    "subscribe_scene": "ADD_SCENE_QR_CODE",
    "qr_scene": 98765,
    "qr_scene_str": ""
}

如果以上使用正确问题依然存在请检查access_token是否过期或重复获取导致失效,详情移步官方文档
