请问这里的accessToken如何生成？我已经通过https://api.weixin.qq.com/sns/oauth2/component/access_token这个请求获取access_token值，{“access_token”:“31_cY8P51yHO49Dlpr-9-PpJfLpFSEvOpOFdRBX2d9NaC0CqGTQBy41-Jl1MZYQg947E2LINbpBMhKQsApJONq41Q”,“expires_in”:7200,“refresh_token”:“31_O-XvEmnpbhwnRjHbtlenvsLYMcXLujFgwHjasa3CgQjb_X22PKtLBfKerJy42WzJJqbWr2kBlrT6p5om5k4ZGA”,“openid”:“oX2kOwKa5ZSkVGbMuxobREixmyW0”,“scope”:“snsapi_userinfo”}，可拿着这里的access_token请求https://api.weixin.qq.com/cgi-bin/user/info?access_token=，反馈说access_token无效。
