微信小程序客服消息自动回复功能laravel-api接口编写
注册微信小程序登录账号,获取appid,appsecret;
在小程序后台配置域名,校验服务器地址URL,拿assces_token
//微信小程序 access_token
public static function Wxxcxtoken()
{
$appid = 'xxx';
$appsecret = 'xxx';
if (!Redis::get('xcxaccess_token')) {
$r = file_get_contents("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$appid&secret=$appsecret");
$data = json_decode($r,true);
Redis::set('xcxaccess_token',$data['access_token']);
Redis::expire('xcxaccess_token' , 7100);//设置有效期为10秒
}
$access_token = Redis::get('xcxaccess_token');
return $access_token;
}
//redis存储操作
public static function Wxxcxsetlog($key,$get,$time=60)
{
Redis::set($key,json_encode($get));
Redis::expire($key , $time);//设置有效期为10秒
}
public static function Wxxcxgetlog($key)
{
return Redis::get($key);
}
public static function Wxxcxdellog($key)
{
return Redis::del($key); // 成功删除返回 删除条数, 失败则返回 false
}
3.标准流程了 下载微信小程序的demo 拿过来改改
/**
* 小程序客服显示控制按钮
*/
public function xcxkfstatus()
{
$status = 1;//1开启 0关闭
return $status;
}
/**
* 客服消息
*/
public function xcxkfxx()
{
//SelectOption::Wxxcxsetlog('xcxkfxx',$_GET);//回调监控
if (isset($_GET['echostr'])) { //校验服务器地址URL
$this->valid();
}else{
$this->responseMsg();
}
}
function valid()
{
$echoStr = $_GET["echostr"];
if($this->checkSignature()){
header('content-type:text');
echo $echoStr;
exit;
}else{
echo $echoStr.'+++'.'cbbcbbhtz';
exit;
}
}
function checkSignature()
{
$signature = $_GET["signature"];
$timestamp = $_GET["timestamp"];
$nonce = $_GET["nonce"];
$token = 'cbbcbbhtz';
$tmpArr = array($token, $timestamp, $nonce);
sort($tmpArr, SORT_STRING);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );
if( $tmpStr == $signature ){
return true;
}else{
return false;
}
}
function responseMsg()
{
$postStr = file_get_contents('php://input'); //此处推荐使用file_get_contents('php://input')获取后台post过来的数据
//SelectOption::Wxxcxsetlog('xcxkfpost',$postStr); //回调监控
if (!empty($postStr) && is_string($postStr)){
$postArr = json_decode($postStr,true);
$id = SelectOption::Wxxcxgetlog('xcxSessionFrom');
SelectOption::Wxxcxsetlog('xcxSessionFrom',isset($postArr['SessionFrom'])?$postArr['SessionFrom']:$id);
if(!empty($postArr['MsgType']) && $postArr['MsgType'] == 'text'){ //用户发送文本消息
$fromUsername = $postArr['FromUserName']; //发送者openid
$media_id = ''; //输入想要回复的图片消息的media_id
$str = SelectOption::Wxxcxgetlog('xcxSessionFrom');
$str = strtr($str, array('\"' => ''));
$content = SelectOption::ProductCreditCardVipLink(strtr($str, array('"' => '')));
$data=array(
"touser"=>$fromUsername,
"msgtype"=>"text",
"text"=>array("content"=>$content)
);
$json = json_encode($data,JSON_UNESCAPED_UNICODE); //php5.4+
$this->requestAPI($json);
}elseif(!empty($postArr['MsgType']) && $postArr['MsgType'] == 'image'){ //用户发送图文消息
$fromUsername = $postArr['FromUserName']; //发送者openid
$media_id = ''; //输入想要回复的图片消息的media_id
$data=array(
"touser"=>$fromUsername,
"msgtype"=>"image",
"image"=>array("media_id"=>$media_id)
);
$json = json_encode($data,JSON_UNESCAPED_UNICODE); //php5.4以上版本才可使用
$this->requestAPI($json);
}elseif($postArr['MsgType'] == 'event' && $postArr['Event']=='user_enter_tempsession'){ //用户进入客服
$fromUsername = $postArr['FromUserName']; //此处为文字回复,不同的回复方式可参考文章顶部第三个链接“回复客户消息”里查看
//id
$content = SelectOption::ProductCreditCardVipLink($postArr['SessionFrom']);
$data=array(
"touser"=>$fromUsername,
"msgtype"=>"text",
"text"=>array("content"=>$content)
);
$json = json_encode($data,JSON_UNESCAPED_UNICODE); //php5.4+
$this->requestAPI($json);
}else{
exit('error');
}
}else{
echo "empty";
exit;
}
}
function requestAPI($json){
$access_token = SelectOption::Wxxcxtoken();
/*POST发送https请求客服接口api*/
$url = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=".$access_token;
//以'json'格式发送post的https请求
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_POST, 1); // 发送一个常规的Post请求
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
if (!empty($json)){
curl_setopt($curl, CURLOPT_POSTFIELDS,$json);
}
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
//curl_setopt($curl, CURLOPT_HTTPHEADER, $headers );
$output = curl_exec($curl);
if (curl_errno($curl)) {
echo 'Errno'.curl_error($curl);//捕抓异常
}
curl_close($curl);
if($output == 0){
echo 'success';exit;
}
}
4.这接口就可以了,对接小程序代码调试一下就ok了
请勿发布不友善或者负能量的内容。与人为善,比聪明更重要!
