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运行良好，但是我无法从本地环境调用远程环境。
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>
我已经能够从本地主机以及在我的开发机器上运行的两个本地虚拟机之间成功地做到这一点。我也可以毫无问题地访问我的自定义 API 的方法。
但是，当我尝试为我的远程测试环境创建一个肥皂客户端时，我能够创建客户端，但是对 $client->login() 的调用或任何后续调用都会导致以下结果：
php > $client = new SoapClient(REMOTE_WSDL_URI,array('trace'=>1));
php > $client->login(API_USER,API_KEY);

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 99.99% 相同：
- 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 配置相同。
- 代码库相同
我已经在互联网上搜索了线索，包括：
- http://www.magentocommerce.com/boards/viewthread/56528/
- http://www.magentocommerce.com/wiki/5__-_modules_and_development/web_services/overriding_an_existing_api_class_with_additional_functionality#wsdl
- 由于“加载外部实体失败”，无法连接到 Magento SOAP API v2
- Magento API SOAP-ERROR: Parsing WSDL: Couldn't load from '[url]/index.php/api/index/index/?wsdl=1' : 找不到开始标签第 56 行的结尾

我已经尝试了最后一个链接中提到的“Content-Length”标头修复，以及我能想到的几乎所有其他内容……难住了。
