//因为公众号请求发送消息接口需要认证（300RMB）,所以这里选择的是测试号接口，一般来说效果差不多//https://mp./debug/cgi-bin/sandboxinfo?action=showinfo&t=sandbox/index首先你得去这里配置测试号，配置的源码如下//封装成一个类，返回给微信，定义一个常量TOKEN值为weixin，用于交互微信
define("TOKEN", "weixin");//自己定义的token 就是个通信的私钥$wechatObj = new wechatCallbackapiTest();$wechatObj->valid();class wechatCallbackapiTest{public function valid(){$echoStr = $_GET["echostr"];if($this->checkSignature()){echo $echoStr;exit;}}public function responseMsg(){//get post data, May be due to the different environments$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];//extract post dataif (!empty($postStr)){$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);$fromUsername = $postObj->FromUserName;$toUsername = $postObj->ToUserName;$keyword = trim($postObj->Content);$time = time();$textTpl = "<xml><ToUserName><![CDATA[%s]]></ToUserName><FromUserName><![CDATA[%s]]></FromUserName><CreateTime>%s</CreateTime><MsgType><![CDATA[%s]]></MsgType><Content><![CDATA[%s]]></Content><FuncFlag>0</FuncFlag></xml>";if(!empty( $keyword )){$msgType = "text";$contentStr = "Welcome to wechat world!";$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);echo $resultStr;}else{echo "Input something...";}}else {echo "";exit;}}private function checkSignature(){$signature = $_GET["signature"];$timestamp = $_GET["timestamp"];$nonce = $_GET["nonce"];$token =TOKEN;$tmpArr = array($token, $timestamp, $nonce);sort($tmpArr);$tmpStr = implode( $tmpArr );$tmpStr = sha1( $tmpStr );if( $tmpStr == $signature ){return true;}else{return false;}}}
测试号配置好了后，就可以开始实现发送微信消息接口了；
/*** @return mixed* 获取微信Access_token*/public function get_wx_access_token(){//将access_token存在session/cookie中//如果access_token在session中并没有过期if (isset($_SESSION['access_token']) && $_SESSION['expire_time'] > time()) {return $_SESSION['access_token'];}//如果access_token不存在或者已经过期，重新获取access_tokenelse {//protected $appid="wx99e125***efaebe9"; //公众号APPID//protected $appsecret="14b01a0afd0ea****7c4a1a4882385c6"; //公众号秘钥$url = "https://api./cgi-bin/token?grant_type=client_credential&appid=" . $this->appid . "&secret=" . $this->appsecret;$arr = $this->my_curl_wx_api($url);//存到session中$access_token = $arr['access_token'];$_SESSION['access_token'] = $arr['access_token'];$_SESSION['expire_time'] = time() + 7200;return $access_token;}}//发送public function service_send(){unset($_SESSION);//获取Access_token$Access_token=$this->get_wx_access_token();//请求地址$url="https://api./cgi-bin/message/custom/send?access_token=".$Access_token;//组装接口Array$array=["touser"=>"o0roI1lyAa_8WgMNUlUOjpMlap_Y", //用户的openid"text"=>["content"=>"China is very NB!!!

上面就是全部代码，喜欢给个赞鼓励鼓励~~~谢谢
