PHP 连接soapServer返回“SOAP: looks like we got no XML document”

1. 写了个soapServer

$server = new SoapServer('xxoo.wsdl');
$server->setClass('URClassName');
$server->handle();

• 新建clientServer去连接

$client = new SoapClient("xxoo.wsdl");
$client->__call($function_name,$arguments);

• server端返回“SOAP: looks like we got no XML document”
• 查看nginx error日志

PHP message: PHP Deprecated:  Automatically populating $HTTP_RAW_POST_DATA is deprecated and will be removed in a future version. To avoid this warning set 'always_populate_raw_post_data' to '-1' in php.ini and use the php://input stream instead. in Unknown on line 0”

• 使用的是php56，按照报错信息提示设置php.ini

always_populate_raw_post_data = -1

• 重启php-fpm
• 连接正常
