（二）網(wǎng)頁授權(quán)獲取用戶基本信息，獲取基本信息

在公眾號的配置過程中，許多開發(fā)者會在菜單中加入html5頁面，有時在頁面內(nèi)需要訪問頁面的用戶信息，此時就需要網(wǎng)頁授權(quán)獲取用戶基本信息

PS：本博文所闡述的微信開發(fā)基于Yii2.0框架

1、設置授權(quán)回調(diào)域名：開發(fā) ---> 接口權(quán)限

　　找到“網(wǎng)頁授權(quán)獲取用戶基本信息”，點擊后面對應的“修改”，在彈框響應位置填寫授權(quán)回調(diào)域名即可，此處的域名不需要加http:// ?（關于網(wǎng)頁授權(quán)回調(diào)域名的說明詳情可參考公眾平臺開發(fā)者文檔）

2、獲取授權(quán)

　　關于OAuth2.0博主參考的是方倍工作室的博文http://www.cnblogs.com/txw1958/p/weixin71-oauth20.html（PS：方倍是一個微信開發(fā)大神，其中的微信開發(fā)內(nèi)容還是比較詳細的，推薦參考），其中詳細剖析了微信官方文檔的相關內(nèi)容，也提供了獲取授權(quán)的更詳細思路和方案。

　　實際上，獲取用戶信息的關鍵在于獲取用戶的openid。博主想要實現(xiàn)用戶點擊公眾號菜單打開頁面即可自動授權(quán)，從而針對該用戶進行數(shù)據(jù)庫操作，于是有下面兩種方式：　

　　（1）利用自定義菜單請求授權(quán)頁面

　　　　自定義菜單后面會單獨寫一篇博文，在這里先簡述一下通過自定義菜單進行授權(quán)，該方法需要高級接口權(quán)限，且局限于關注公眾號的用戶直接從菜單進入頁面。

<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":"快遞服務",
</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":"發(fā)快遞",
</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":"快遞查詢",
</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> }';

登錄后復制

　　需要授權(quán)的view直接在url處填寫微信提供的授權(quán)請求地址，其中：

appid：填寫微信公眾平臺基本配置中的AppID；
redirect_uri：填寫授權(quán)完成后跳轉(zhuǎn)的頁面地址，即自己的html5頁面；
state：跳轉(zhuǎn)至回調(diào)頁面所帶參數(shù)；

response_type：網(wǎng)頁授權(quán)的兩種scope，微信官方文檔中說明如下：

1<span>、以snsapi_base為scope發(fā)起的網(wǎng)頁授權(quán)，是用來獲取進入頁面的用戶的openid的，并且是靜默授權(quán)并自動跳轉(zhuǎn)到回調(diào)頁的。用戶感知的就是直接進入了回調(diào)頁（往往是業(yè)務頁面）
</span>2、以snsapi_userinfo為scope發(fā)起的網(wǎng)頁授權(quán)，是用來獲取用戶的基本信息的。但這種授權(quán)需要用戶手動同意，并且由于用戶同意過，所以無須關注，就可在授權(quán)后獲取該用戶的基本信息。

登錄后復制

按照此方法點擊“商城”即可接收到返回的openid，繼而進行下一步用戶信息的獲取。　

　　（2）利用JS自動請求授權(quán)頁面

　　　　這個方法相對而言比較笨拙，步驟略復雜，但目前能解決需求還沒有研究簡化方法，且由于頁面的跳轉(zhuǎn)多數(shù)情況下訪問頁面的時間會增加，但相比于前一個方法，該方法可以獲取到非關注用戶的基本信息。有些程序可能涉及到頁面分享，程序沒有強制關注但其他用戶通過分享直接進入頁面也需要記錄用戶信息，此時可以考慮該方法。（微信開發(fā)相關的代碼博主封裝成工具類調(diào)用，這里先貼用到的部分，以后整理完成會全部貼出來并附下載鏈接）

　　　　該方法的思路為：js請求鏈接獲取code ---> 利用code換取openid ---> 得到用戶基本信息

? ? ? ? ? ? ?程序要求用戶打開產(chǎn)品列表即獲取用戶信息并存入數(shù)據(jù)庫，其中設計了幾個變量作用如下：

? ? ? ? $refresh：判斷頁面是否刷新，由于首次打開頁面未進行oauth驗證時才自動請求驗證，避免反復刷新，這里用回調(diào)的state參數(shù)作為判斷依據(jù)且設state=1（若有特定參數(shù)需要可將state賦值為所需值）；

? ? ? ? $request：即為驗證請求地址

? ? ? ? f. 視圖自動刷新

? ? ? ? 只需要在視圖中添加以下js代碼即可

<span> 1</span> <script type="text/javascript">
<span> 2</span>
