由于“无法加载外部实体"，无法连接到 Magento SOAP API v2

问题描述

我无法使用 PHP 连接到 Magento SOAP API v2.出现的错误是:

I am unable to connect to the Magento SOAP API v2 using PHP. The error that occurs is:

PHP 致命错误:未捕获的 SoapFault 异常:[WSDL] SOAP 错误:解析 WSDL:无法从 'http://www.example.com/index.php/api/v2_soap/index/wsdl/1/':无法加载外部实体 "http://www.example.com/index.htmlphp/api/v2_soap/index/wsdl/1/"

PHP Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://www.example.com/index.php/api/v2_soap/index/wsdl/1/' : failed to load external entity "http://www.example.com/index.php/api/v2_soap/index/wsdl/1/"

看起来，WSDL 正在加载，但它包含的外部 SOAP 文件没有加载.

As it seems, the WSDL is being loaded, but the external SOAP file which it includes not.

PHP 连接代码:

$client = new SoapClient('http://www.example.com/api/v2_soap?wsdl=1');
$session = $client->login('username', 'password');

<小时>

从 v2_soap?wsdl=1 文件中截取:

Snip from v2_soap?wsdl=1 file:

<service name="MagentoService">
    <port name="Mage_Api_Model_Server_V2_HandlerPort" binding="typens:Mage_Api_Model_Server_V2_HandlerBinding">
        <soap:address location="http://www.example.com/index.php/api/v2_soap/index/"/>
    </port>
</service>

Magento 版本为 1.5.1.0.

推荐答案

此问题是由于服务器无法从本地机器访问文件造成的.所以可能的原因可能是 DNS 服务器或/etc/hosts，但它实际上是一个 .htaccess 文件阻止了除我们的开发计算机之外的任何主机.这导致了 403 Forbidden 错误，进而导致了 SOAP 错误等等.

This problem is caused by the server not being able to access the file from the local machine. So the possible cause could've been the DNS server or /etc/hosts, but it was actually a .htaccess file blocking any hosts except from our development computers. This resulted in a 403 Forbidden error, which resulted in the SOAP error and so on..
