（一）微信公众号开发基本配置

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：

登入後複製

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
