网页授权获取用户基本信息---获取code码
今天碰到微信公众号实现菜单跳转请求用户参数
获取code码碰到了这个问题
网页微信第三方登录-redirect_uri参数错误
通过网页授权access_token和openid获取用户基本信息（支持UnionID机制）
目录
2 第二步：通过code换取网页授权access_token
4 第四步：拉取用户信息(需scope为 snsapi_userinfo)
第一步：用户同意授权，获取code
在确保微信公众账号拥有授权作用域（scope参数）的权限的前提下（服务号获得高级接口后，默认拥有scope参数中的snsapi_base和snsapi_userinfo），引导关注者打开如下页面：
https://open.weixin.qq.com/connect/oauth2/authorize?appid=APPID&redirect_uri=REDIRECT_URI&response_type=code&scope=SCOPE&state=STATE#wechat_redirect 若提示“该链接无法访问”，请检查参数是否填写错误，是否拥有scope参数对应的授权作用域权限。
尤其注意：由于授权操作安全等级较高，所以在发起授权请求时，微信会对授权链接做正则强匹配校验，如果链接的参数顺序不对，授权页面将无法正常访问
参考链接(请在微信客户端中打开此链接体验):
scope为snsapi_base
https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx520c15f417810387&redirect_uri=https%3A%2F%2Fchong.qq.com%2Fphp%2Findex.php%3Fd%3D%26c%3DwxAdapter%26m%3DmobileDeal%26showwxpaytitle%3D1%26vb2ctag%3D4_2030_5_1194_60&response_type=code&scope=snsapi_base&state=123#wechat_redirect
scope为snsapi_userinfo
https://open.weixin.qq.com/connect/oauth2/authorize?appid=wxf0e81c3bee622d60&redirect_uri=http%3A%2F%2Fnba.bluewebgame.com%2Foauth_response.php&response_type=code&scope=snsapi_userinfo&state=STATE#wechat_redirect
尤其注意：跳转回调redirect_uri，应当使用https链接来确保授权code的安全性。
参数说明
| 参数 | 是否必须 | 说明 |
|---|---|---|
| appid | 是 | 公众号的唯一标识 |
| redirect_uri | 是 | 授权后重定向的回调链接地址， 请使用 urlEncode 对链接进行处理 |
| response_type | 是 | 返回类型，请填写code |
| scope | 是 | 应用授权作用域，snsapi_base （不弹出授权页面，直接跳转，只能获取用户openid），snsapi_userinfo （弹出授权页面，可通过openid拿到昵称、性别、所在地。并且， 即使在未关注的情况下，只要用户授权，也能获取其信息 ） |
| state | 否 | 重定向后会带上state参数，开发者可以填写a-zA-Z0-9的参数值，最多128字节 |
| #wechat_redirect | 是 | 无论直接打开还是做页面302重定向时候，必须带此参数 |
注意：其中redirect_uri必须到http://tool.chinaz.com/tools/urlencode.aspx把你要请求的地址转urlEncode码然后请求
如果跳转的请求是action或者别的（控制层）方法参数不能加载方法体中接收参数值就可以
用户同意授权后
如果用户同意授权，页面将跳转至 redirect_uri/?code=CODE&state=STATE。
code说明 ： code作为换取access_token的票据，每次用户授权带上的code将不一样，code只能使用一次，5分钟未被使用自动过期。
我的链接转码过前为：https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx7f1ceeace0d20918&redirect_uri=https://bw.cross.echosite.cn/shjz/people!addPeople213.do&code=CODE&scope=snsapi_userinfo&state=1&connect_redirect=1#wechat_redirect
我的链接转码过后为：https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx7f1ceeace0d20918&redirect_uri=https%3a%2f%2fbw.cross.echosite.cn%2fshjz%2fpeople!addPeople213.do&code=CODE&scope=snsapi_userinfo&state=1&connect_redirect=1#wechat_redirect
发送到微信点开第一步
然后参数到了后台
其中addPeople213这个方法不能带参数否则会报错，然后在方法体中接收code码就ok了
到此code码就获取到了
