Magento Soap API在本地工作但不是远程工作

Question

我为Magento Enterprise 1.11创建了一个自定义API。通过Soap v1调用API在我的本地开发环境中工作正常，但是我无法从本地环境调用到远程环境。

在我的localdev上使用php交互式shell：

php > $client = new SoapClient(WSDL_URI,array('trace'=>1));
php > $client->login(API_USER,API_KEY);
php > var_dump($client->__getLastResponse());
string(538) "<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="urn:Magento" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><SOAP-ENV:Body><ns1:loginResponse><loginReturn xsi:type="xsd:string">f0eec73e49665aaf9cc4a6644fba5dc6</loginReturn></ns1:loginResponse></SOAP-ENV:Body></SOAP-ENV:Envelope>

我已经能够从localhost以及在我的开发机器上运行的两个本地VM之间成功完成此操作。我也可以毫无问题地访问我的自定义API的方法。

但是，当我尝试在我的远程测试环境中创建一个soap客户端时，我能够创建客户端，但是对$ client-> login（）或任何后续调用的调用会产生以下结果：

php > $client = new SoapClient(REMOTE_WSDL_URI,array('trace'=>1));
php > $client->login(API_USER,API_KEY);
PHP Warning:  Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://REMOTE_HOST/index.php/api/index/index/wsdl/1/' : failed to load external entity "http://REMOTE_HOST/index.php/api/index/index/wsdl/1/" in php shell code:1

当我点击//REMOTE_HOST/index.php/api/?wsdl时，我得到了标准的Magento WSDL。

这两个环境的相同性为99.99％：

服务器版本：Apache / 2.2.16（Debian）（本地开发和远程）
PHP 5.3.18（本地开发）5.3.19（远程主机）
Apache / PHP配置是相同的。
代码库是相同的

我已经搜索了intewebs的线索，包括：

我已经尝试了倒数第二个链接中提到的“内容长度”标题修复，以及我能想到的其他所有内容......难倒。
