【问题描述】：

我正在尝试与支付网关 (FirstData) 进行交互。到目前为止，我已经创建了 cURL 请求，并终于让它工作了。现在我可以生成包含在 SOAP 中的 XML。我收到一条错误消息：

输入 SOAP 请求格式不正确。异常是 org.xml.sax.SAXParseException：文档中根元素之前的标记必须格式正确。

这是我提供的 xml：

$this->xml = "<?xml version=\"1.0\"?>";
$this->xml = "<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\">";
$this->xml = "<SOAP-ENV:Header />";
$this->xml = "<SOAP-ENV:Body>";
$this->xml = "<fdggwsapi:FDGGWSApiOrderRequest xmlns:fdggwsapi=\“http://secure.linkpt.net/fdggwsapi/schemas_us/fdggwsapi\">";
$this->xml = "<v1:Transaction xmlns:v1=\"http://secure.linkpt.net/fdggwsapi/schemas_us/v1\">";
$this->xml = "<v1:CreditCardTxType>";
$this->xml = "<v1:Type>sale</v1:Type>";
$this->xml = "</v1:CreditCardTxType>";
$this->xml = "<v1:CreditCardData>";
$this->xml = "<v1:CardNumber>4012000033330026</v1:CardNumber>";
$this->xml = "<v1:ExpMonth>12</v1:ExpMonth>";
$this->xml = "<v1:ExpYear>12</v1:ExpYear>";
$this->xml = "</v1:CreditCardData>";
$this->xml = "<v1:Payment>";
$this->xml = "<v1:ChargeTotal>12</v1:ChargeTotal>";
$this->xml = "</v1:Payment>";
$this->xml = "</v1:Transaction>";
$this->xml = "</fdggwsapi:FDGGWSApiOrderRequest>";
$this->xml = "</SOAP-ENV:Body>";
$this->xml = "</SOAP-ENV:Envelope>";

return $this->xml;

我找不到太多关于此的信息，并且已经尝试了所有方法。以下是我通过 cURL 请求发送的标头：

$headers = array(
        "Content-type: text/xml;charset=\"utf-8\"", 
        "Accept: text/xml", 
        "Cache-Control: no-cache", 
        "Pragma: no-cache", 
        "SOAPAction: \"run\"", 
        "Content-length: ".strlen($this->genXML()),
        );

*genXML() 包含上面列出的 XML 的 XML 消息

感谢任何信息。

【参考方案1】：

你的意思是$this->xml .= "..."？否则每次都只是覆盖字符串，对吧？
