PHP在用SOAP协议做接口的时候，经常会碰到如下问题,不是不成功，而是偶尔不成功，实在让人费解！

ERR: SOAP-ERROR: Parsing WSDL: Couldn‘t load from ‘http://www.xxxxx.com/member/member_sync.php?wsdl‘ : failed to load external entity "http://www.xxxxx.com/member/member_sync.php?wsdl"

查找日志发现：

NOTIC: [2] SoapClient::SoapClient(): I/O warning : failed to load external entity "http://www.xxxxx.com/member/member_sync.php?wsdl" /home/wwwroot/default/xxxxx.com/App/Modules/Admin/Action/OrderAction.class.php 第 112 行.

网上查找很多资料，有开启selinux、关闭soap缓存、开启openssl等等答案，但尝试过后都不尽人意，现终极解决办法：

只需把php的客户端SoapClient的wsdl模式修改为non-wsdl模式，即可解决!

wsdl模式：

<?php

$url = "http://xxxxx.org/member/member_sync.php?wsdl";

$client = new SoapClient ( $url );

$arr = array (

‘username‘ => ‘test123‘, 

‘company‘ => ‘深圳市xxxxx科技有限公司‘, 

‘password‘ => md5 ( md5 ( "test123" ) ), 

‘encrypt_code‘ => ‘thisisencryptcode‘ ); //加密串，必须

$result = $client->common_func ( ‘sync_member‘, json_encode ( $arr ) );

var_dump ( $result );

?>

non-wsdl模式：

<?php

$client = new SoapClient(null,array(‘location‘=>‘http://www.zgzszj.com/member/member_sync.php‘,uri => ‘member_sync.php‘));

$arr = array (

‘username‘ => ‘test123‘, 

‘company‘ => ‘深圳市xxxxx科技有限公司‘, 

‘password‘ => md5 ( md5 ( "test123" ) ), 

‘encrypt_code‘ => ‘thisisencryptcode‘ ); //加密串，必须

$result = $client->common_func ( ‘sync_member‘, json_encode ( $arr ) );

var_dump ( $result );

?>
