群组和双向回呼是一个级别的 应为他们都是属于子账户的操作 所以 他们的子帐号鉴权信息验证是一样

在sdk包里添加

/**
   添加组  
    */
      function CreateGroup($Group)
      {   
        //子帐号鉴权信息验证,对必选参数进行判空。
        $auth=$this->subAuth();
        if($auth!=""){
            return $auth;
        }
        // 拼接请求包体 
        if($this->BodyType=="json"){
           $body= "{'from':'$from','to':'$to','customerSerNum':'$customerSerNum','fromSerNum':'$fromSerNum','promptTone':'$promptTone'}";
        }else{
           $body= "<Request>
  <name>$Group</name>
  <type>0</type>
  <permission>0</permission>
  <declared>云通讯技术交流</declared>
</Request> ";
        }
        $this->showlog("request body = ".$body);
        // 大写的sig参数  
        $sig =  strtoupper(md5($this->SubAccountSid . $this->SubAccountToken . $this->Batch));
        // 生成请求URL
        $url="https://$this->ServerIP:$this->ServerPort/$this->SoftVersion/SubAccounts/$this->SubAccountSid/Group/CreateGroup?sig=$sig";
        $this->showlog("request url = ".$url);
        // 生成授权:子帐号Id + 英文冒号 + 时间戳 
        $authen=base64_encode($this->SubAccountSid . ":" . $this->Batch);
        // 生成包头 
        $header = array("Accept:application/$this->BodyType","Content-Type:application/$this->BodyType;charset=utf-8","Authorization:$authen");
        // 发请求
        $result = $this->curl_post($url,$body,$header);
        $this->showlog("response body = ".$result);
        if($this->BodyType=="json"){//JSON格式
           $datas=json_decode($result); 
        }else{ //xml格式
           $datas = simplexml_load_string(trim($result," \t\n\r"));
        }
      //  if($datas == FALSE){
//            $datas = new stdClass();
//            $datas->statusCode = '172003';
//            $datas->statusMsg = '返回包体错误'; 
//        }
        return $datas;
    }

再自己新建一个调用文件,我起的名字叫做CreateGroup.php

尽量留下原来例子的语法,便于及时的参考

效果图

云通讯 添加群组_php

重点就是鉴权的验证,子账户当然不能和主账号混为一谈。
