  • 微信公众号接口生成菜单(链接、文本回复及图文消息)

    1、获取access_token
    2、获取图文消息media_id
    3、确定文本回复key,构建菜单json字符串
    4、请求菜单创建接口

    1、获取access_token
    方便起见,用微信公众平台接口调试工具(http://mp.weixin.qq.com/debug?token=1606511159&lang=zh_CN)获取access_token

    获取过程可能会遇到白名单问题,在公众号开发基本配置中临时修改下白名单,不出意外access_token获取成功

    2、因菜单包含图文消息菜单,需获取图文消息media_id,方便起见利用postman调用接口获取。(上述第一步获取access_token也可以直接用postman)

    调试公众号POST请求(获得后台素材media_id)

    接口地址

    http请求方式: POST
    https://api.weixin.qq.com/cgi-bin/material/batchget_material?access_token=ACCESS_TOKEN

    参数说明

    参数是否必须说明
    type 素材的类型,图片(image)、视频(video)、语音 (voice)、图文(news)
    offset 从全部素材的该偏移位置开始返回,0表示从第一个素材 返回
    count 返回素材的数量,取值在1到20之间

    将刚刚获得的基础token拼入接口地址填入postman 选择请求方式为POST

    添加请求参数

     返回结果中获取media_id

    3、包含直接回复文本的菜单,确定key,构建菜单json字符串

    $jsonMenu = '
        {
            "button": [
                {
                    "name": "资源管理", 
                    "sub_button": [
                        {
                            "type": "view", 
                            "name": "我的记录", 
                            "url": "http://m.test.net/h5/my/index", 
                            "sub_button": [ ]
                        }, 
                        {
                            "type": "click", 
                            "name": "使用说明1", 
                            "key": "SYSM-001", 
                            "sub_button": [ ]
                        }, 
                        {
                            "type": "click", 
                            "name": "使用说明2", 
                            "key": "SYSM-002", 
                            "sub_button": [ ]
                        }
                    ]
                }, 
                {
                    "name": "加盟培训", 
                    "sub_button": [
                        {
                            "type": "view", 
                            "name": "安全通告", 
                            "url": "http://mp.weixin.qq.com/s/haHruj5RgoawpYOoEUA1CA", 
                            "sub_button": [ ]
                        }, 
                        
                        {
                           "type": "view_limited", 
                            "name": "图文消息1",
                            "media_id": "O4NvReZyZPUCT4efE3q6FwtfaTmWyEgIbLg2arIGiA0"
                        }, 
                        {
                            "type": "view_limited", 
                            "name": "图文消息2", 
                            "media_id": "O4NvReZyZPUCTyefE3q6FwlTyoldJsDiHbFKCwdmPSc"
                        }, 
                    ]
                }, 
            ]
        }';

    文本回复的菜单需在代码中作相应处理,检测event中click,匹配key值,回复对应文本消息内容

    public function weixin(){
            $postStr = $this->input->raw_input_stream;
            
            $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
    
            if(!empty($postObj)){
                $MsgType = $postObj->MsgType;
    
                switch($MsgType){
                    case "text":
                        $resultStr = $this->_handle_text($postObj);
                        break;
                    case "event":
                        $resultStr = $this->_handle_event($postObj);
                        break;
                    default:
                        $resultStr = "Unknow msg type: ".$MsgType;
                        break;
                }
                echo $resultStr;
            }
            else{
                echo 'error';
            }
        }
    
        function _handle_event($postObj){
            $openid = strval($postObj->FromUserName);
    
            $EventKey = strval($postObj->EventKey);
    
            ll('Weixinlib');
            $userinfo   = $this->weixinlib->get_user_info($openid); // 获取平台用户信息  array  
    
    
            $msgType = 'text';
            switch (strtolower($postObj->Event))
            {
                case "subscribe":
                    $content = $this->_handle_event_subscribe($postObj,$userinfo);
                    break;
                case "scan":
                    $content = $this->_handle_event_scan($postObj,$userinfo);
                    break;
                case "click"://文本消息回复处理
                    $content = $this->_handle_event_click($postObj);
                    break;
                default :
                    $content = "Unknow Event: ".$postObj->Event;
                    break;
            }
            $resultStr = $this->_response($postObj, $content,$msgType);
            return $resultStr;
        }
    
       function _handle_event_click($postObj){
            $scene = $postObj->EventKey;
            return $this->_click_handle_scene($scene);
        }
       function _click_handle_scene($scene){
            switch ($scene){
                case 'SYSM-001':
                    $resultStr = "SYSM-001对应的文本消息";
                    break;
                case 'SYSM-002':
                    $resultStr = "SYSM-001对应的文本消息";
                    break;
                default:
                    $resultStr = "unknow click";
                    break;
    
            }
            return $resultStr;
        }
    
       function _response($object, $content,$msgType = 'text'){
            if(empty($content)){
                return;
            }
            if($msgType == 'text'){
                return $this->_response_text($object, $content);
            }else if($msgType == 'news'){ //图文消息
                return $this->_response_news($object, $content);
            }
        }
    
        private function _response_text($object, $content, $flag=0)
        {
            $textTpl = "<xml>
                            <ToUserName><![CDATA[%s]]></ToUserName>
                            <FromUserName><![CDATA[%s]]></FromUserName>
                            <CreateTime>%s</CreateTime>
                            <MsgType><![CDATA[text]]></MsgType>
                            <Content><![CDATA[%s]]></Content>
                            <FuncFlag>%d</FuncFlag>
                        </xml>";
            $resultStr = sprintf($textTpl, $object->FromUserName, $object->ToUserName, time(), $content, $flag);
            return $resultStr;
        }

    调用创建菜单接口,创建菜单

    $url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=$access_token";
    $output =  http_post($url, $jsonMenu);

    成功返回:{"errcode":0,"errmsg":"ok"}
