api-PHP调用java发邮件的服务,收件箱发现部分乱码,麻烦大家给我看看,谢谢

        $content = '活生生的';
        $email = 'test_email@gmail.com';

        $myHttp = new MyHttp();

        $data = array(
                'tenantid'       => UserLogicModel::getTenantId(),//租户id
                'suject'         => $subject,
                'text'           => base64_encode($content),
                'tomail'         => $email,
                'attachmentPath' => $attachmentPath,         //"attachmentPath":"/usr/local/files/入职offer通知.doc",
                'attachmentName' => $attachmentName,         //"attachmentName":"入职offer通知.doc"
        );
        


        $json_data = json_encode($data);
        $params    = "params=".$json_data;
        $res       = $myHttp->send(Dict::$STATIC_SEND_MAIL_URL, $params, "POST", "");

class MyHttp {
    
    //发送网络请求
    public function send($url,$data,$method,$token){
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
        curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)');
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($ch, CURLOPT_AUTOREFERER, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        //$header = array(
        //    'u:1234567777',
        //    't:1234568888',
        //);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('token:$token'));
        $tmpInfo = curl_exec($ch);
        if (curl_errno($ch)) {
          return curl_error($ch);
        }
        $stat=curl_getinfo($ch,CURLINFO_HTTP_CODE); //我知道HTTPSTAT码哦～
        curl_close($ch);
        switch ($stat) {
            case '200':
                if(empty($tmpInfo))
                    $tmpInfo='{"stat":"ok"}';
                break;
            
            default:
                # code...
                break;
        }
        if(empty($tmpInfo))
            $tmpInfo="";

        //记录与api接口之间的通信数据到日志
        \Think\Log::write("http $method req[$stat]:res($tmpInfo)",'ALERT');
        return $tmpInfo;
    }

上面是请求java接口的curl代码,无论我怎么求里面加指定charset=UTF-8,java端

 $head    = array("Content-Type: application/json;charset=UTF-8"); //解决java接口乱码问题,直接抛送json数据
        curl_setopt($ch, CURLOPT_HTTPHEADER,$head);
        加上这句代码,马上就接受不到参数.

回复内容：

        $content = '活生生的';
        $email = 'test_email@gmail.com';

        $myHttp = new MyHttp();

        $data = array(
                'tenantid'       => UserLogicModel::getTenantId(),//租户id

                'tomail'         => $email,
                'attachmentPath' => $attachmentPath,         //"attachmentPath":"/usr/local/files/入职offer通知.doc",

其实应该是可以得，不知道你的java接口是不是规定了必须是json格式的，如果是，那么你这一句修改下：

$params    = "params=".$json_data;    //你这是一个string，因为你前面加了params=这个，所以你直接把$json_data传送过去试试
