关于微信公众号自动回复文本、图片以及图文

1.微信公众号自动回复文本：

       首先我们应该增加reply_id以及内容（content）到数据表rh_mp_reply_text,然后根据reply_id查找表rh_mp_rule的信息关键字。然后我们在回复信息的那个方法里写入以下代码：

       

               case 'text':
                    $reply=M('mp_reply_text')->find($reply_id);
                    if($reply){
                        $reply_text=$reply['content'];
                    }else{
                        $reply_text="出错了";
                    }
                    return ResponsePassive::text($request['fromusername'],$request['tousername'],$reply_text);
                    break;

      下面是将页面获取的内容写入数据表：

          

                        $model=M('mp_reply_text');
			$content=I('post.content');
			$arr['content']=$content;
			$ret=$model->add($arr);
			$m=M('mp_rule');
			$mp=getCurrentMp();
			$a=array(
				'mpid'=>$mp['id'],
				'keyword'=>I('post.keyword'),
				'type'=>'text',
				'reply_id'=>$ret
				);
			$m->add($a);
			if($ret){
				$this->ajaxReturn(array('status'=>1,'msg'=>'添加成功','url'=>U('replytext')));
			}else{
				$this->ajaxReturn(array('status'=>0,'msg'=>'添加失败'));
			}

2.回复图片

        首先我们要将图片上传到微信服务器上，我们需要调用接口https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=$accessToken&type=image，这样他会给我们返回一个media_id,这样我们在写入数据表。

			$keyword=I('post.keyword');
			$media_id=I('media_id');
			$url=I('post.url');//图片在本地服务器上的路径
			if(empty($keyword)|| empty($url)){
				$this->ajaxReturn(array('status'=>0,'msg'=>'必须输入关键字和选择图片'));
				exit;
			}
			if(empty($media_id)){
				$accessToken=getAccess_token();
				include APP_PATH . 'LaneWeChat/lanewechat.php';	
				$url1="https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=$accessToken&type=image";
				$file=realpath('.'. $url);//相对路径->绝对路径
				$data['media']=Curl::addFile($file);			
				$ret=Curl::callWebServer($url1,$data,'post',1,0);
				if(isset($ret['media_id'])){
					$media_id=$ret['media_id'];
					$url=$ret['url'];
				}else{
					$ret['fail']='本地图片上传公众号失败';
					$this->ajaxReturn(array('status'=>1,'msg'=>$ret));
					exit;
				}
				$data['media_id']=$media_id;
				$data['url']=$url;
				$reply_id=M('mp_reply_image')->add($data);
				$mp=getCurrentMp();
				$arr=array(
					'mpid'=>$mp['id'],
					'type'=>'image',
					'keyword'=>$keyword,
					'reply_id'=>$reply_id
					);
				$ret=M('mp_rule')->add($arr);
				if($ret){
						$this->ajaxReturn(array('status'=>1,'msg'=>'添加成功','url'=>U('replyimage')));
				}else{
					$this->ajaxReturn(array('status'=>0,'msg'=>'添加失败'));
				}
			}

   

               case 'image':
                    $reply=M('mp_reply_image')->find($reply_id);
                    if($reply){
                        $media_id=$reply['media_id'];
                        return ResponsePassive::image($request['fromusername'],$request['tousername'],$media_id);
                    }else{
                        $reply_text="出错了";
                        return ResponsePassive::text($request['fromusername'],$request['tousername'],$reply_text);
                    }
                    
                    break;

3.回复图文

$result=I('post.');
			if(empty($result['keyword'])|| empty($result['url'])){
				$this->ajaxReturn(array('status'=>0,'msg'=>'必须输入关键字和选择图片'));
				exit;
			}
			if(empty($result['media_id'])){
				$accessToken=getAccess_token();
				include APP_PATH . 'LaneWeChat/lanewechat.php';	
				$url1="https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=$accessToken&type=image";
				$file=realpath('.'. $result['url']);//相对路径->绝对路径
				$data['media']=Curl::addFile($file);			
				$ret=Curl::callWebServer($url1,$data,'post',1,0);
				if(isset($ret['media_id'])){
					$media_id=$ret['media_id'];
					$url=$ret['url'];
				}else{
					$ret['fail']='本地图片上传公众号失败';
					$this->ajaxReturn(array('status'=>1,'msg'=>$ret));
					exit;
				}
				$data['title']=$result['title'];
				$data['description']=$result['content'];
				$data['picurl']=$url;
				$data['url']=$result['content_source_url'];
				$reply_id=M('mp_reply_news')->add($data);
				$mp=getCurrentMp();
				$arr=array(
					'mpid'=>$mp['id'],
					'type'=>'news',
					'keyword'=>$result['keyword'],
					'reply_id'=>$reply_id
					);
				$ret=M('mp_rule')->add($arr);
				if($ret){
					$this->ajaxReturn(array('status'=>1,'msg'=>'添加成功','url'=>U('replynews')));
				}else{
					$this->ajaxReturn(array('status'=>0,'msg'=>'添加失败'));
				}
			}

 case 'news':
                    $reply=M('mp_reply_news')->find($reply_id);
                    if($reply){
                        $item[]=ResponsePassive::newsItem($reply['title'],$reply['descrpition'],$reply['picurl'],$reply['url']);
                        return ResponsePassive::news($request['fromusername'],$request['tousername'],$item);
                    }else{
                        $reply_text="出错了";
                        return ResponsePassive::text($request['fromusername'],$request['tousername'],$reply_text);
                    }
                    break;

这样就可以实现回复图文、文本、图片。
