【微信公众号开发】自我学习第七章：公众号自定义菜单栏

官方公众号权限

首先明确一个问题：我之前申请的是未认证订阅号，能调用的接口权限有限，我们需要申请测试公众号 (注：在开发者工具里面的公众平台测试帐号)，申请完毕了之后配置成和我们之前的订阅号一样的配置！这样我们的公众平台测试账号是有权限调用自定义菜单栏的接口的！

官方自定义菜单栏API

规范：
1、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。

2、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。

代码实现：

private function curl_http($url, $type = 'get', $res = 'json', $arr=array())  {      //获取百度      //1.初始化curl      $ch = curl_init();      //2.设置curl的参数      curl_Setopt( $ch,CURLOPT_URL,$url );      curl_Setopt( $ch,CURLOPT_RETURNTRANSFER,1 );      curl_setopt( $ch, CURLOPT_HTTPHEADER, array( 'Expect:' ) );      if($type == 'post') {          curl_setopt($ch, CURLOPT_POST, 1);          curl_setopt($ch, CURLOPT_POSTFIELDS, $arr);      }      //3.采集      $output= curl_exec($ch);      //4.关闭      if($res == 'json'){          //【这里是处理curl错误的】          if(curl_errno($ch)){ //成功错误码是0              return curl_errno($ch);          }          curl_close($ch);          return json_decode($output, true);      }  }  /**   * @Route("/accesstoken", name="system_share_accesstoken", methods={"POST", "GET"})   */  private function accesstokenAction()  {      if(isset($_SESSION['accessToken']) && isset($_SESSION['expires_time'] ) && $_SESSION['expires_time'] > time()){          return $_SESSION['accessToken'];      }else{          $appid ='申请的测试appid';          $secret = '申请的测试secret';          $url = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid='.$appid.'&secret='.$secret;          $data = $this->curl_http($url);          $_SESSION['accessToken'] = $data['access_token'];          $_SESSION['expires_time'] = time()+7200;          return $data['access_token'];      }  }  /**   * @Route("/config", name="system_share_config", methods={"POST", "GET"})   */  public function configAction(Request $request)  {      $accesstoken = $this->accesstokenAction();      $url = 'https://api.weixin.qq.com/cgi-bin/menu/create?access_token='.$accesstoken;      //准备参数      $configData = array(          'button' => array(              array(                  "name" => urlencode("开发"),                  "sub_button" => array(                      array(                          "name" => urlencode("微信开发"),                          "key" => 'weixin',                          "type" => "click"                      ),                      array(                          "name" => urlencode("Ubuntu系统"),                          "key" => 'ubuntu',                          "type" => "click"                      ),                  ),              ),              array(                  "name" => urlencode("娱乐"),                  "sub_button" => array(                      array(                          "name" => "acfun",                          "url" => urlencode("http://www.acfun.cn/"),                          "type" => "view"                      ),                      array(                          "name" => urlencode("百度"),                          "url" => urlencode("http://www.baidu.cn/"),                          "type" => "view"                      )                  ),              ),              array(                  "name" => urlencode("关于自己"),                  "sub_button" => array(                      array(                          "name" => urlencode("cndn博客"),                          "url" => urlencode("http://blog.csdn.net/qq_31617637"),                          "type" => "view"                      ),                      array(                          "type" => "scancode_push",                          "name" => urlencode("扫码自动跳转"),                          "key" => "rselfmenu_0_1",                          "sub_button" => [ ]                      ),                      array(                          "type" => "scancode_waitmsg",                          "name" => urlencode("扫码不自动跳转"),                          "key" => "scan_url",                          "sub_button" => [ ]                      ),                      array(                          "type" => "location_select",                          "name" => urlencode("地址定位"),                          "key" => "area",                          "sub_button" => [ ]                      )                  ),              ),          )      );      $configData = urldecode(json_encode($configData));      $data = $this->curl_http($url, 'post', 'json', $configData);      dump($data);die;  }

注意：

数组中的文字必须要通过URL编码处理，不然会报40033错误！

click等事件的处理机制，其实在我们触发事件之后，本质还是当前用户发送XML文件向微信平台请求，即自定义菜单事件推送 ，我们还是需要处理：

if( strtolower( $postObj->MsgType ) == 'event' ){    if( strtolower( $postObj->Event ) == 'subscribe' ){        $toUser   = $postObj->FromUserName;        $fromUser = $postObj->ToUserName;        $time     = time();        $msgType  = 'text';        $content  = '您好，欢迎关注：【踏凌霄】'."\n".'目前支持功能：'."\n".'【1】汉译英：（回复）翻译一+内容'."\n".'【2】英译汉：（回复）翻译二+内容'."\n".'【3】回复（微信开发）查看关于微信开发的博文'."\n".'【4】天气：（回复）天气+地区（拼音）例如（天气baoding）'."\n"."\n"."踏南天，碎凌霄!么么哒！鸡年大吉！";        $info = $this->txtFormatForXml($toUser, $fromUser, $time, $msgType, $content);        echo $info;    }    //点击事件触发    if( strtolower( $postObj->Event ) == 'click' ){        $toUser   = $postObj->FromUserName;        $fromUser = $postObj->ToUserName;        $time     = time();        $msgType  = 'text';        $content  = $postObj->EventKey;        $info = $this->txtFormatForXml($toUser, $fromUser, $time, $msgType, $content);        echo $info;    }    //扫码事件触发    if( strtolower( $postObj->Event ) == 'scancode_waitmsg' ){        $toUser   = $postObj->FromUserName;        $fromUser = $postObj->ToUserName;        $time     = time();        $msgType  = 'text';        $content  = '扫描信息'."\n".$postObj->ScanCodeInfo."\n".'扫描结果'."\n".$postObj->ScanResult;        $info = $this->txtFormatForXml($toUser, $fromUser, $time, $msgType, $content);        echo $info;    }}
