(2) Web page authorization to obtain basic user information, obtain basic information

During the configuration process of public accounts, many developers will add HTML5 pages to the menu. Sometimes it is necessary to access the user information of the page within the page. In this case, the web page authorization is required to obtain the user’s basic information

PS: The WeChat development described in this blog post is based on the Yii2.0 framework

1. Set authorization callback domain name: Development ---> Interface permissions

Find "Web page authorization to obtain basic user information", click the corresponding "Modify" at the end, and fill in the authorization callback domain name in the response position of the pop-up box. The domain name here does not need to add http:// (For details about the web page authorization callback domain name, please refer to the public platform developer documentation)

2. Obtain authorization

About OAuth2.0 bloggers refer to the blog post of Fangbei Studio http://www.cnblogs.com/txw1958/p/weixin71-oauth20.html (PS: Fangbei is a WeChat development master , the WeChat development content is relatively detailed, recommended reference), which analyzes the relevant content of WeChat official documents in detail, and also provides more detailed ideas and solutions for obtaining authorization.

In fact, the key to obtaining user information is to obtain the user's openid. The blogger wants to realize that the user can automatically authorize the page by clicking on the official account menu, so as to perform database operations on the user, so there are the following two methods: 　

(1) Use the custom menu to request authorization page

I will write a separate blog post after the custom menu. Here I will briefly describe authorization through the custom menu. This method requires advanced interface permissions and is limited to users who follow the official account and enter the page directly from the menu. .

<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> }';

Copy after login

　For views that require authorization, directly fill in the authorization request address provided by WeChat at the url, where:

appid: Fill in the AppID in the basic configuration of the WeChat public platform;
redirect_uri: fill in the address of the page that will jump after the authorization is completed, that is, your own html5 page;
state: parameters for jumping to the callback page;

response_type: two scopes for web page authorization. The official WeChat documentation explains as follows:

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。

Copy after login

Click "Mall" according to this method to receive the returned openid, and then proceed to the next step of obtaining user information. 　

　 (2) Use JS to automatically request the authorization page

This method is relatively clumsy and the steps are slightly complicated. However, there is currently no simplified method that can solve the needs. In addition, due to page jumps, the time to access the page will increase in most cases, but compared to the previous A method that can obtain basic information about non-following users. Some programs may involve page sharing. The program does not force following, but other users who enter the page directly through sharing also need to record user information. In this case, you can consider this method. (The code bloggers related to WeChat development are encapsulated into tool calls. The used parts are posted here first. After the arrangement is completed, all will be posted with download links)

The idea of this method is: js request link to get code ---> Use code in exchange for openid ---> Get basic user information

$refresh: Determine whether the page is refreshed. Since the page is opened for the first time without oauth verification, verification is automatically requested to avoid repeated refreshes. Here, the state parameter of the callback is used as the basis for judgment and state=1 (if there is a specific Parameters need to be able to assign the state to the required value);

$request: This is the verification request address

f. View automatically refreshes

Just add the following js code to the view

<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><span> 7</span>         <span>if</span>(refresh == 1<span>){
</span><span> 8</span>             console.<span>log</span>(1<span>);
