由于“无法加载外部实体"，因此无法连接到Magento SOAP API v2. [英] Unable to connect to Magento SOAP API v2 due to "failed to load external entity"

问题描述

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

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/"

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，正在加载WSDL，但其中未包含外部SOAP文件.

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');

从v2_soap?wsdl = 1文件中摘录:

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

此问题是由服务器无法从本地计算机访问文件引起的.因此，可能的原因可能是DNS服务器或/etc/hosts，但实际上是一个.htaccess文件，阻止了除我们开发计算机以外的所有主机.这导致了403 Forbidden错误，从而导致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..
