微信用户量很多，那么我们如何开始一个属于自己的微信小程序呢，因为自己不是高微信的。最近研究了一下微信，只是先微信的一个小功能。那么下面开始微信开发的搭建。这里如何申请微信公众号自己去官网申请就行了。最后登录该公众号。下面从我公众号开始讲

开启开发者模式

• 点击左侧菜单的基本配置

• 然后是做微信开发我们得有一个属于自己的服务器，方便在上面编写代码。这里我用新浪云作为自己的服务器。
  新浪云服务注册地址

新浪云申请

• 进入新浪云后选择控制台sae

• 然后点击创建新应用 按钮 后弹出选择服务器的界面，我们选择标准版的，因为是免费的。

• 至于里面的二级域名这就是看个人喜好设置的了。设置好之后我们回到父页面，就是点击创建新应用的那个界面就会看到我们创建的应用了，我这里是我实现创立好的。

微信开发者配置

• 通过上面我们就已经有了服务器了，下面我们来填写微信的相关配置

• 上面的url就填写我们的新建的新浪云应用的地址，至于token随便你自己填写，只不过你得记住，因为在新浪云服务器里写代码的时候需要用到。

• 然后点击确定你的微信公众号就成为了开发者模式了。下面我们开始在服务器上实现我们的功能

微信服务器的代码编写

• 点击我们的应用的连接进入应用界面

• 选择左侧菜单树种的应用后再点击代码管理，在右侧就可以看到应用的编辑代码超链接了，点击超链接

• 这里我们可以选择我们index.php进行代码的修改，或者是实现。直接将下面的代码赋值到你的服务器里

• token一定要和微信配置中的相同

• 然后让我们看看效果吧
