本文寫的是使用者公眾號輸入關鍵詞，微信伺服器被動回覆內容。

首先在後臺上傳關鍵詞與回覆內容

前臺頁面內容如下

<form class="layui-form" action="{:U('replyText')}" style="padding-right: 10px;" method="post">
    <div class="layui-form-item">
        <label class="layui-form-label">回覆關鍵詞</label>
        <div class="layui-input-block">
            <input type="text" name="keyword" required  lay-verify="required"   placeholder="請輸入關鍵詞" autocomplete="off" class="layui-input">
        </div>
    </div>
   
    <div class="layui-form-item">
        <label class="layui-form-label">回覆內容</label>
        <div class="layui-input-block">
            <textarea name="content" required  lay-verify="required" placeholder="請輸入內容" class="layui-textarea"></textarea>
        </div>
    </div>
    
    <div class="layui-form-item">
        <div class="layui-input-block">
            <button class="layui-btn" lay-submit lay-filter="SBT">提交</button>
            <a href="{:U('keywords',['type'=>'text'])}" class="layui-btn layui-btn-primary">返回</a>
        </div>
    </div>
</form>

<script>
  // alert('123');
layui.use('form', function(){
    var form = layui.form
    form.on('submit(SBT)', function(data){
        var load = layer.load();
        $.post("{:U('replyText')}",data.field,function (res) {
            //replyText即為上傳文字的方法
           layer.alert(res.msg);
            layer.close(load);
            // layer.msg(res.msg,{time:1000},function () {
            //     window.location.href=res.url;
            // });
          
        })
        return false;
    });

});

</script>
 

後臺控制器程式碼

mp_rule 表結構

mp_reply_text表結構

// 上傳文字
    public function replytext($type=""){
     if(empty($type)){
  	    $type = 'text'; 
  	        
     }
     $keyword=I('post.keyword');
     $content = I('post.content');
        $mp=$this->mp;
        $mp_id=$mp['id'];
        $data2['mp_id']=$mp_id;
        $data2['keyword']=$keyword;
        $data2['type']='text';
        $data2['status'] = $mp['is_use'];
        $data1['content'] = $content;
        $ret = M('mp_reply_text')->add($data1);
        $data2['reply_id'] = $ret;
        M('mp_rule')->add($data2);
        $this->ajaxReturn(array('msg'=>'上傳成功'));
  
   	}
 

新增進資料表中後，當用戶像公眾號輸入關鍵字，就需要回復內容了

這是lanewechat中的wechatrequest.php中的部分程式碼，當用戶輸入的是文字時回覆內容

 public static function text(&$request){
        $mpid = $_GET['id'];
        $content = $request['content'];
        $where['mp_id'] = $mpid;
        $where['keyword'] = $content;
        $data = M('mp_rule')->where($where)->find();
        if($data){

            //傳送訊息中有這個關鍵字
            $reply_id = $data['reply_id'];
            $type = $data['type'];
            if($type == 'text'){
                $reply = M('mp_reply_text')->find($reply_id);
                $reply_text = $reply['content'];
                return ResponsePassive::text($request['fromusername'], $request['tousername'], $reply_text);
            }   
            echo "success";
        }
    }
 

此時向公眾號傳送關鍵字時會有文字回覆
