关于微信公众号自动回复文本、图片以及图文 - 好文

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。
