【微信公众平台开发】创建自定义菜单（四）

1.根据微信公众平台文档，得知创建自定义菜单有如下规则：

a.目前自定义菜单最多包括3个一级菜单，每个一级菜单最多包含5个二级菜单。一级菜单最多4个汉字，二级菜单最多7个汉字，多出来的部分将会以“...”代替。请注意，创建自定义菜单后，由于微信客户端缓存，需要24小时微信客户端才会展现出来。建议测试时可以尝试取消关注公众账号后再次关注，则可以看到创建后的效果。

注：所以最多只能创建15个功能菜单，多了就出错了！

b.

目前自定义菜单接口可实现两种类型按钮，如下：

click：用户点击click类型按钮后，微信服务器会通过消息接口推送消息类型为event的结构给开发者（参考消息接口指南），并且带上按钮中开发者填写的key值，开发者可以通过自定义的key值与用户进行交互；view：用户点击view类型按钮后，微信客户端将会打开开发者在按钮中填写的url值（即网页链接），达到打开网页的目的，建议与网页授权获取用户基本信息接口结合，获得用户的登入个人信息。

接口调用请求说明

http请求方式：POST（请使用https协议） https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN

2.根据文档提供的规则和接口调用说明，封装成一个类编写代码如下

class WeChatCreateMenu{<span style="white-space:pre"></span>//判断token是否过期，如果过期重新获取，不然直接从数据库取public function Get_access_token($appid,$secret){$db = DBManage::getInstance();$db->ConnDB();$sql = "select * from t_token";if($db-> GetEffectRows($sql) > 0){$sql = "select * from t_token where TokenFlag='sd'";$res = $db->GetData($sql);while( $obj = mysqli_fetch_object($res)){if($obj->TokenTime-60 > time()) //Token还没过期{return $obj->Token;}else  //过期{break;}}}$url="https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$appid."&secret=".$secret;$json=self::DoCurlGetRequest($url);$retData=json_decode($json,true);if(!$retData){return false;}$token = $retData['access_token'];$expire = $retData['expires_in'];$oldTime = time() + $expire;$sql = "select * from t_token";if($db-> GetEffectRows($sql) == 0) //无数据{$sql = "insert into t_token values('sd','$token','$oldTime')";$db->ExecSql($sql);}else //更新 数据{$sql = "update t_token set Token='$token',TokenTime='$oldTime' where TokenFlag='sd'";$db->ExecSql($sql);}//file_put_contents("debug.txt", "token====".$token.PHP_EOL,FILE_APPEND);return $token;}//因为url是https 所有请求不能用file_get_contents,用curl请求json 数据private function DoCurlGetRequest($url){$ch = curl_init();curl_setopt($ch, CURLOPT_URL,$url);curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);$result = curl_exec($ch);curl_close($ch);return $result;}function DoCurlPostRequest($url, $jsonData){$con = curl_init((string)$url);curl_setopt($con,CURLOPT_HEADER, false);curl_setopt($con, CURLOPT_POSTFIELDS,$jsonData);curl_setopt($con, CURLOPT_POST, true);curl_setopt($con, CURLOPT_RETURNTRANSFER, true);curl_setopt($con,CURLOPT_SSL_VERIFYPEER,false);  //略过证书验证$result = curl_exec($con) ;if(curl_errno($con)){file_put_contents("tmp.txt", curl_errno($con).PHP_EOL,FILE_APPEND);}return $result;}public  function  CreateMenu(){$token = $this->Get_access_token("wxa5fd3441ffa34","a49921c7d71b57850c57d1f589");$url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=".$token;  //自定义菜单接口$menuData = array('button' => array(array('name' => '走进窗骑','sub_button' => array(array('type' =>'click','name' => '微官网','key' => 'sdwgw'),array('type' =>'view','name' => '全品牌推广','url' => 'http://128.88.44.11/WXProject/DataHtml/html/qpptg.html'),array('type' =>'view','name' => '3D影视包装','url' => 'http://128.88,44,11/WXProject/DataHtml/html/3d.html'),array('type' =>'view','name' => '互动体验','url' => 'http://128.88.44.11/WXProject/DataHtml/html/hudong.html'),array('type' =>'view','name' => '合作客户','url' => 'http://128.88.44.11/WXProject/DataHtml/html/partner.html'))),array('name' => '微楼书','sub_button' =>array(array('type' =>'click','name' => '项目概况','key' => 'xmgk'),array('type' =>'view','name' => '区位配套','url' => 'http://128.88.44.11/WXProject/DataHtml/qwpt.html'),array('type' =>'view','name' => '景观鉴赏','url' => 'http://128.88.44.11/WXProject/WXPicBrowser/jgjd.php'),array('type' =>'view','name' => '户型展示','url' => 'http://128.88.44.11/WXProject/WXPicBrowser/jdhx.php'),array('type' =>'view','name' => '3D视频','url' => 'http://128.88.44.11/WXProject/DataHtml/video.html'))     ),array('name' => "互动体验",'sub_button' => array(array('type' =>'click','name' => '会员中心','key' => 'hyzx'),array('type' =>'view','name' => '看房预约','url' => 'http://128.88.44.11/WXProject/DataPHP/seehouse.php'),array('type' =>'view','name' => '智能问答','url' => 'http://128.88.44.11/WXProject/DataPHP/test.php'),array('type' =>'view','name' => '一键功能','url' => 'http://128.88.44.11/WXProject/onetouchdial.html#mp.weixin.qq.com'),array('type' =>'click','name' => '刮刮乐','key' => 'ggl')))));$data = JSON($menuData);$this->DoCurlPostRequest($url,$data);  //以https发送post请求}}

写完上面的类，直接在index.php，调用就行了；然后按前面几篇介绍的方法传到sae上面，运行测试

3.大概思路：根据微信的文档说明，首先按规则创建好菜单，然后按规定写好创建自定义菜单接口，接着用https发送post请求，微信服务器收到请求，判断发送过来的接口没错；微信服务器发送创建好的菜单到每一位微信用户的客户端显示。

有同学说没有数据库操作类，我也直接贴出来吧！

<?phpclass DBManage{private $conn;private static $_instance;public function __clone(){trigger_error("Clone is not allow!",E_USER_ERROR);}public static function getInstance(){if(!self::$_instance instanceof self){self::$_instance = new self;}return self::$_instance;}function ConnDB(){$this->conn = mysqli_init();$ret = mysqli_real_connect($this->conn, "122.128.111.111", "root", "mima222", "wxdb", 6033, "t_userinfo", MYSQLI_CLIENT_FOUND_ROWS);}function ExecSql($sql){$ret = mysqli_query($this->conn, $sql);return $ret;}function GetEffectRows($sql){$ret = mysqli_query($this->conn, $sql);return mysqli_num_rows($ret);}function GetData($sql){$ret = mysqli_query($this->conn, $sql);return $ret;}}?>
