php实现基于微信公众平台开发SDK(demo)扩展的方法
本文实例讲述了php实现基于微信公众平台开发SDK(demo)扩展的方法。分享给大家供大家参考。具体分析如下:
该扩展基于官方的微信公众平台SDK,这里只做了简单地封装,实现了一些基本的功能(如天气查询,翻译,自动聊天机器人,自定义菜单接口)仅供学习之用.代码如下:
define("TOKEN","xingans"); $wechatObj=newwechatCallbackapiTest(); $wechatObj->responseMsg(); classwechatCallbackapiTest { //签名验证公共接口 publicfunctionvalid() { $echoStr=$_GET["echostr"]; if($this->checkSignature()){ echo$echoStr; exit; } } //主入口处理函数 publicfunctionresponseMsg() { $postStr=$GLOBALS["HTTP_RAW_POST_DATA"]; if(!emptyempty($postStr)){ $postObj=simplexml_load_string($postStr,'SimpleXMLElement',LIBXML_NOCDATA); $msgType=trim($postObj->MsgType); switch($msgType){ case'text': $resultStr=$this->handleText($postObj); break; case'event': $resultStr=$this->handleEvent($postObj); break; default: $resultStr=$this->handleDefault($postObj); break; } echo$resultStr; }else{ echo"Error"; exit; } } //处理文本消息 privatefunctionhandleText($obj){ $keyword=trim($obj->Content); if(preg_match('/天气/',$keyword)){ $contentStr=$this->handleWeather($obj); }elseif(preg_match('/翻译/',$keyword)){ $contentStr=$this->handleTranslation($obj); }else{ $contentStr=$this->handleChat($obj); } return$this->handleStr($obj,$contentStr); } //处理天气 privatefunctionhandleWeather($obj){ $keyword=mb_substr($obj->Content,-2,2,'utf-8'); $zone=mb_substr($obj->Content,0,-2,'utf-8'); if($keyword=='天气'&&!emptyempty($zone)){ $zoneArr=json_decode(file_get_contents('http://api.k780.com:88/?app=weather.city&format=json'),true); $zoneArr=$zoneArr['result']; $cityId=''; foreach($zoneArras$value){ if($zone==$value['citynm']){ $cityId=$value['weaid']; break; } } if(!emptyempty($cityId)){ $data=file_get_contents("http://api.k780.com:88/?app=weather.today&weaid=$cityId&appkey=10638&sign=3736578f099375665f9f141a6326b757&format=json"); $data=json_decode($data); $contentStr="今天是:".$data->result->days.",".$data->result->week.",".$data->result->citynm."天气:".$data->result->weather."n温度:".$data->result->temperature.", ".$data->result->wind_direction.",".$data->result->wind_power.",最低温度:".$data->result->temp_low.",最高温度:".$data->result->temp_high; }else{ $contentStr='找不到输入的城市!'; } }else{ $contentStr='输入的查询格式不正确!'; } return$contentStr; } //处理翻译 privatefunctionhandleTranslation($obj){ $keyword=mb_substr($obj->Content,0,2,'utf-8'); $words=mb_substr($obj->Content,2,220,'utf-8'); if($keyword=='翻译'&&!emptyempty($words)){ $data=file_get_contents('http://fanyi.youdao.com/openapi.do?keyfrom=zfsblog&key=364295447&type=data&doctype=json&version=1.1&q='.urlencode($words)); $data=json_decode($data,true); switch($data['errorCode']){ case'0': $contentStr=$data['translation'][0]; break; case'20': $contentStr='要翻译的文本过长'; break; case'30': $contentStr='无法进行有效的翻译'; break; case'40': $contentStr='不支持的语言类型'; break; case'50': $contentStr='无效的key'; break; default: $contentStr='Error'; break; } }else{ $contentStr='输入的翻译格式不正确!'; } return$contentStr; } //处理聊天信息 privatefunctionhandleChat($obj){ $keywords=$obj->Content; $curlPost=array("chat"=>$keywords); $ch=curl_init();//初始化curl curl_setopt($ch,CURLOPT_URL,'http://www.xiaojo.com/bot/chata.php');//抓取指定网页 curl_setopt($ch,CURLOPT_HEADER,0);//设置header curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);//要求结果为字符串且输出到屏幕上 curl_setopt($ch,CURLOPT_POST,1);//post提交方式 curl_setopt($ch,CURLOPT_POSTFIELDS,$curlPost); $data=curl_exec($ch);//运行curl curl_close($ch); if(!emptyempty($data)){ $contentStr=$data; }else{ $ran=rand(1,5); switch($ran){ case1: $contentStr="小九今天累了,明天再陪你聊天吧"; break; case2: $contentStr="小九睡觉喽~~"; break; case3: $contentStr="呼呼~~呼呼~~"; break; case4: $contentStr="你话好多啊,不跟你聊了"; break; case5: $contentStr="你话好多啊,不跟你聊了"; break; } } return$contentStr; } //创建自定义菜单 publicfunctioncreateMenu($data,$token){ $ch=curl_init(); curl_setopt($ch,CURLOPT_URL,"https://api.weixin.qq.com/cgi-bin/menu/create?access_token=".$token); curl_setopt($ch,CURLOPT_CUSTOMREQUEST,"POST"); curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false); curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false); curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0(compatible;MSIE5.01;WindowsNT5.0)'); curl_setopt($ch,CURLOPT_FOLLOWLOCATION,1); curl_setopt($ch,CURLOPT_AUTOREFERER,1); curl_setopt($ch,CURLOPT_POSTFIELDS,$data); curl_setopt($ch,CURLOPT_RETURNTRANSFER,true); $result=curl_exec($ch); curl_close($ch); return$result; } //查询自定义菜单 functiongetMenu($token){ $url="https://api.weixin.qq.com/cgi-bin/menu/get?access_token=$token"; $ch=curl_init($url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);//获取数据返回 curl_setopt($ch,CURLOPT_BINARYTRANSFER,true);//在启用CURLOPT_RETURNTRANSFER时候将获取数据返回 curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false); curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false); return$output=curl_exec($ch); } //删除自定义菜单 publicfunctiondeleteMenu($token){ $url="https://api.weixin.qq.com/cgi-bin/menu/delete?access_token=".$token; $ch=curl_init(); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false); curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false); $result=curl_exec($ch); curl_close($ch); return$result; }
