我要假设你使用的是WS-I标准的SOAP API V2作为我有这个相同的问题;如果没有，则这可能仍然适用。我从来没有能够连接到V2 API，而它是WS-I标准，这是我发现了这个错误。

I'm going to assume you are using the WS-I compliant SOAP API v2 as I had this exact same issue; if not, then this still might apply. I was never able to connect to the v2 API without it being WS-I compliant, which is how I found this bug.

如果你有看应用程序/ code /核心/法师/原料药/型号/服务器/ WSI /适配器/ Soap.php 文件，你会看到在基本上分成两部分的公共运行功能 - 1为实际的SOAP响应WSDL定义响应和1。

If you have a look at the app/code/core/Mage/Api/Model/Server/Wsi/Adapter/Soap.php file you will see in the public run function that is essentially split into two parts - 1 for the WSDL definition response and 1 for the actual SOAP response.

在SOAP响应有一点串替换回事，替换＆LT;肥皂：操作的soapAction =＆GT;＆LT; / SOAP：操作＆gt; 的＆LT;肥皂：操作的soapAction =/＆GT; 等。这显然​​是导致与内容长度计算的问题 - 这也是发生在WSDL定义响应，但它似乎并没有被引起的问题。

In the SOAP response there is a bit of string replacing going on, substituting <soap:operation soapAction=""></soap:operation> for <soap:operation soapAction="" /> and so on. This is evidently causing an issue with the content-length calculation - this is also occurring in the WSDL definition response, but it doesn't seem to be causing an issue.

我能够通过更换与下面的code中的尝试大括号中的code成功连接到SOAP API。基本上，我结束了清除头和重新计算的内容长度 在的的字符串替换发生了：

I was able to successfully connect to the SOAP API by replacing the code between the try curly brackets with the code below. Basically, I ended up clearing the headers and recalculating the content-length AFTER the string replacement had taken place:

            $this->_instantiateServer();

            $content = preg_replace(
                        '/(\>\<)/i',
                        ">\n<",
                        str_replace(
                                '<soap:operation soapAction=""></soap:operation>',
                                "<soap:operation soapAction=\"\" />\n",
                                str_replace(
                                        '<soap:body use="literal"></soap:body>',
                                        "<soap:body use=\"literal\" />\n",
                                        preg_replace(
                                            '/<\?xml version="([^\"]+)"([^\>]+)>/i',
                                            '<?xml version="$1" encoding="'.$apiConfigCharset.'"?>',
                                            $this->_soap->handle()
                                        )
                                )
                        )
                    );

            $this->getController()->getResponse()
                      ->clearHeaders()
                      ->setHeader('Content-Type','text/xml; charset='.$apiConfigCharset)
                      ->setHeader('Content-Length',strlen($content))
                      ->setBody($content);

希望这有助于
