（二）网页授权获取用户基本信息，获取基本信息

在公众号的配置过程中，许多开发者会在菜单中加入HTML5页面，有时在页面内需要访问页面的用户信息，此时就需要网页授权获取用户基本信息

PS：本博文所阐述的微信开发基于Yii2.0框架

1、设置授权回调域名：开发 ---> 接口权限

　　找到“网页授权获取用户基本信息”，点击后面对应的“修改”，在弹框响应位置填写授权回调域名即可，此处的域名不需要加http:// （关于网页授权回调域名的说明详情可参考公众平台开发者文档）

2、获取授权

　　关于OAuth2.0博主参考的是方倍工作室的博文http://www.cnblogs.com/txw1958/p/weixin71-oauth20.html（PS：方倍是一个微信开发大神，其中的微信开发内容还是比较详细的，推荐参考），其中详细剖析了微信官方文档的相关内容，也提供了获取授权的更详细思路和方案。

　　实际上，获取用户信息的关键在于获取用户的openid。博主想要实现用户点击公众号菜单打开页面即可自动授权，从而针对该用户进行数据库操作，于是有下面两种方式：　

　　（1）利用自定义菜单请求授权页面

　　　　自定义菜单后面会单独写一篇博文，在这里先简述一下通过自定义菜单进行授权，该方法需要高级接口权限，且局限于关注公众号的用户直接从菜单进入页面。

<span> 1</span> <span>$menu</span> = '<span>{
</span><span> 2</span> <span>  "button":[
</span><span> 3</span> <span>    {
</span><span> 4</span> <span>      "type": "view",
</span><span> 5</span> <span>      "name": "商城",
</span><span> 6</span> <span>      "url": "https://open.weixin.qq.com/connect/oauth2/authorize?appid=xxx&redirect_uri=http://tx.heivr.com/index.php&response_type=code&scope=snsapi_base&state=1#wechat_redirect"
</span><span> 7</span> <span>    },
</span><span> 8</span> 
<span> 9</span> <span>    {
</span><span>10</span> <span>      "name":"快递服务",
</span><span>11</span> <span>      "sub_button":[
</span><span>12</span> <span>        {
</span><span>13</span> <span>           "type":"click",
</span><span>14</span> <span>           "name":"发快递",
</span><span>15</span> <span>           "key":"express"
</span><span>16</span> <span>        },
</span><span>17</span> <span>        {
</span><span>18</span> <span>           "type":"click",
</span><span>19</span> <span>           "name":"快递查询",
</span><span>20</span> <span>           "key":"ww"
</span><span>21</span> <span>        }
</span><span>22</span> <span>      ]
</span><span>23</span> <span>    },
</span><span>24</span> <span>  ]
</span><span>25</span> }';

Nach dem Login kopieren

　　需要授权的view直接在url处填写微信提供的授权请求地址，其中：

appid：填写微信公众平台基本配置中的AppID；
redirect_uri：填写授权完成后跳转的页面地址，即自己的html5页面；
state：跳转至回调页面所带参数；

response_type：网页授权的两种scope，微信官方文档中说明如下：

1<span>、以snsapi_base为scope发起的网页授权，是用来获取进入页面的用户的openid的，并且是静默授权并自动跳转到回调页的。用户感知的就是直接进入了回调页（往往是业务页面）
</span>2、以snsapi_userinfo为scope发起的网页授权，是用来获取用户的基本信息的。但这种授权需要用户手动同意，并且由于用户同意过，所以无须关注，就可在授权后获取该用户的基本信息。

Nach dem Login kopieren

按照此方法点击“商城”即可接收到返回的openid，继而进行下一步用户信息的获取。　

　　（2）利用JS自动请求授权页面

　　　　这个方法相对而言比较笨拙，步骤略复杂，但目前能解决需求还没有研究简化方法，且由于页面的跳转多数情况下访问页面的时间会增加，但相比于前一个方法，该方法可以获取到非关注用户的基本信息。有些程序可能涉及到页面分享，程序没有强制关注但其他用户通过分享直接进入页面也需要记录用户信息，此时可以考虑该方法。（微信开发相关的代码博主封装成工具类调用，这里先贴用到的部分，以后整理完成会全部贴出来并附下载链接）

　　　　该方法的思路为：js请求链接获取code ---> 利用code换取openid ---> 得到用户基本信息

程序要求用户打开产品列表即获取用户信息并存入数据库，其中设计了几个变量作用如下：

$refresh：判断页面是否刷新，由于首次打开页面未进行oauth验证时才自动请求验证，避免反复刷新，这里用回调的state参数作为判断依据且设state=1（若有特定参数需要可将state赋值为所需值）；

$request：即为验证请求地址

f. 视图自动刷新

只需要在视图中添加以下js代码即可

<span> 1</span> <script type="text/javascript">
<span> 2</span> 
<span> 3</span>     <span>//</span><span>自动请求获取code</span>
<span> 4</span>     $(<span>function</span><span>(){
</span><span> 5</span>         <span>var</span> refresh = <?= <span>$refresh</span>; ?><span>;
</span><span> 6</span>         <span>var</span> request = '<?= $request[0]; ?>'<span>;
</span><span> 7</span>         <span>if</span>(refresh == 1<span>){
</span><span> 8</span>             console.<span>log</span>(1<span>);
</span><span> 9</span>             location =<span> request;
</span><span>10</span> <span>        }
</span><span>11</span> <span>    });
</span><span>12</span> </script>
