（一）微信公众号开发基本配置，信公众开发基本配置

作为用代码进行微信开发者或要实现事件响应等功能，微信开发基本配置是必不可少的环节，本文大致梳理开发配置的流程。

1、登入微信公众平台：开发 ---> 基本配置

2、在基本配置页面有“服务器配置”，默认是未启用状态，需要我们先点击“修改配置”进行相关项目填写

3、填写以下项目内容

URL：必须以http://开头，目前仅支持80端口，服务器地址必须是可访问的有效地址（注：用本文中URL举例，曾经看到一篇博文将URL地址填为http://tx.heivr.com/token，但亲测实际开发中无法响应事件，修改URL至具体的文件即可成功）；
EncodingAESKey随机生成即可；

token：微信特别强调了填写的URL需要响应token，因此在index.php中需要进行验证，代码如下：

<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>10</span> <span>     * 签名验证
</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> }

在浏览器中运行index.php若程序无误即可看到返回的字符串，且此时完成验证，并将代码中的token填写到基本配置中的相应位置，点击提交。（注：提交后可能会出现“token验证失败”的提示，若检查代码及各项参数无误，则需多点击几次提交即可成功）

4、提交成功后，点击“开启”按钮，即进入开发者模式，该模式开启后功能 ---> 自定义菜单等部分功能即不可用，若想使用点击“停用”即可
