As a WeChat developer using code or to implement functions such as event response, the basic configuration of WeChat development is an indispensable link. This article roughly outlines the development configuration process.

1. Log in to the WeChat public platform: Development ---> Basic configuration

2. There is "Server Configuration" on the basic configuration page. It is not enabled by default. We need to click "Modify Configuration" first to fill in the relevant items

3. Fill in the following items

• URL: must start with http://, currently only supports port 80, the server address must be an accessible and valid address (Note: Using the URL in this article as an example, I once saw a blog post that The URL address is filled in as http://tx.heivr.com/token, but in actual development, the event cannot be responded to. Modifying the URL to a specific file will succeed );
• EncodingAESKey can be randomly generated;
• token: WeChat particularly emphasizes that the filled in URL needs to respond to the token, so it needs to be verified in index.php, the code is as follows:

  <span> 1</span> <?<span>php
  </span><span> 2</span> <span>define</span>("TOKEN", "此处填写你设置的token值"<span>);
  </span><span> 3</span> 
  <span> 4</span> <span>$wechatObj</span> = <span>new</span><span> CallbackAPI;
  </span><span> 5</span> <span>$wechatObj</span>-><span>valid();
  </span><span> 6</span> 
  <span> 7</span> <span>class</span><span> CallbackAPI {
  </span><span> 8</span> 
  <span> 9</span>     <span>/*</span><span>*

  </span><span>11</span> <span>     * @return [type] [description]
  </span><span>12</span>      <span>*/</span>
  <span>13</span>      <span>public</span> <span>function</span><span> valid() {
  </span><span>14</span>         <span>$echoStr</span> = <span>$_GET</span>["echostr"<span>];
  </span><span>15</span>         <span>$signature</span> = <span>$_GET</span>["signature"<span>];
  </span><span>16</span>         <span>$timestamp</span> = <span>$_GET</span>["timestamp"<span>];
  </span><span>17</span>         <span>$nonce</span> = <span>$_GET</span>["nonce"<span>];
  </span><span>18</span>         <span>$token</span> =<span> TOKEN;
  </span><span>19</span>         <span>//</span><span>将token、timestamp、nonce按字典序排序</span>
  <span>20</span>         <span>$tmpArr</span> = <span>array</span>(<span>$token</span>, <span>$timestamp</span>, <span>$nonce</span><span>);
  </span><span>21</span>         <span>sort</span>(<span>$tmpArr</span><span>);      
  </span><span>22</span>         <span>$tmpStr</span> = <span>implode</span>(<span>$tmpArr</span><span>);
  </span><span>23</span>         <span>//</span><span>对tmpStr进行sha1加密</span>
  <span>24</span>         <span>$tmpStr</span> = <span>sha1</span>(<span>$tmpStr</span><span>);
  </span><span>25</span>         <span>if</span>(<span>$tmpStr</span> == <span>$signature</span><span>){
  </span><span>26</span>             <span>header</span>('content-type:text'<span>);
  </span><span>27</span>             <span>echo</span> <span>$echoStr</span><span>;
  </span><span>28</span>             <span>exit</span><span>;
  </span><span>29</span> <span>        }
  </span><span>30</span> <span>    }
  </span><span>31</span> }

  Copy after login

  Run index.php in the browser. If the program is correct, you can see the returned string, and the verification is completed at this time. Fill in the token in the code into the corresponding position in the basic configuration, and click Submit. (Note: After submission, a "token verification failed" prompt may appear. If the code and parameters are correct, you need to click a few more times to submit successfully )

4. After the submission is successful, click the "Enable" button to enter the developer mode. After this mode is enabled, some functions ---> Custom menu and other functions will be unavailable. If you want to use it, click "Stop" Just use "
