教程二:回复简单的文本消息,回复文本消息
前面我们完成了微信公众号的`服务器配置`,并且完成了token的验证.
现在我们尝试回复用户发送给公众号的文本消息.
1.首先我们确定`微信配置`为`启用`状态.
2.然后我们进入微信公众平台的`沙盒测试账号`,因为在这种状态下对已各种借口的权限限制比较小,而且
这是一个独立的公众号,有独立的`appID` `appsecret` `url` `token`,不影响线上环境!
这是一个独立的公众号,有独立的`appID` `appsecret` `url` `token`,不影响线上环境!
这是一个独立的公众号,有独立的`appID` `appsecret` `url` `token`,不影响线上环境!
(重要的事情说三遍)
3.进入`沙盒测试账号`时根据提示用自己的微信扫码相应的二维码,完成后会出现测试账号配置信息,
根据自己的需要修改`URL`和`Token`
我这里依旧使用之前我们SAE的URL和Token,分别是:
URL:http://weixinshow001.sinaapp.com
Token:weixin
4.接下来,我们要修改我们之前的`index.php`文件了,
因为之前的功能只是提供了token的验证,
没有实现任何消息回复功能,
现在我们利用已经写好的一个wechat的php库,来实现文本信息的回复.
有效代码如下:
<?<span>php </span><span>/*</span><span>* * 微信公众平台 PHP SDK 示例文件 </span><span>*/</span> <span>//</span><span>导入wechat的php类库</span> <span>require</span>('wechat/Wechat.php'<span>); </span><span>/*</span><span>* * 微信公众平台演示类 </span><span>*/</span> <span>//</span><span>继承Wechat类,这里实现了消息回复和接受的基本功能</span> <span>class</span> TestWechat <span>extends</span><span> Wechat { </span><span>/*</span><span>* * 收到文本消息时触发,回复收到的文本消息内容 * * @return void </span><span>*/</span> <span>//</span><span>step 2 // 收到用户发给公众号的文本信息的时候会调用此函数</span> <span>protected</span> <span>function</span><span> onText() { </span><span>//</span><span>$this->getRequest('content') 返回的是用户发送给公众号的文本</span> <span>$this</span>->responseText('收到了文字消息:' . <span>$this</span>->getRequest('content'<span>)); } } </span><span>//</span><span>step 1 //新建一个Wechat的实例,用于处理用户发送过来的信息 //aeskey 可以随便写,测试账号没有使用消息加密 //token以及appid与`测试号管理`页的信息相同,不是公众号的信息 //token以及appid与`测试号管理`页的信息相同,不是公众号的信息 //token以及appid与`测试号管理`页的信息相同,不是公众号的信息</span> <span> (重要的事情说三遍) </span><span>$wechat</span> = <span>new</span> TestWechat(<span>array</span><span>( </span>'token' => 'weixin', 'aeskey' => 'xxx', 'appid' => 'wx5d1fb434a1652ae8', 'debug' => <span>true</span><span> )); </span><span>$wechat</span>-><span>run(); 复制代码</span>
代码的处理流程是,
step 1:创建一个TestWechat的实例写入各种配置数据.
step 2:当用户向公众号发送信息时,读取用户发送过来的文本内容并作为文本信息回复给用户.
最终的代码结构是:
我们在微信中和测试号的通讯如下:
wechat的php在附件中,
有关wechat-php的使用我们会在后面更为详细的介绍.
