Question

我已经到处搜索，但是找不到解决我问题的方法。

我正在尝试连接到API，但出现此错误“看起来我们没有XML文档”。

我向创建API的公司发送了一封电子邮件，他们说问题出在我的服务器上。我也在本地环境中尝试过，但这是同样的问题。

代码：

 $soap = new soapclient( $WS_URL, array('trace' => 1, 'exceptions' => 0));
 $result = $soap->authenticate( $API_KEY );
 $APISession = $result[1];

try {
  echo '<pre>';
    var_dump($soap);
     echo '</pre>';
} catch (Exception $e) {
    echo($soap->__getLastResponse());
    echo PHP_EOL;
    echo( $soap->__getLastRequest());
}

//140 - Document number
//4 - Document Type

 $getdocumentpdflink = $soap->getdocumentpdflink($APISession, 140, 4);

 echo '<pre>';
 print_r($getdocumentpdflink);
 echo '</pre>';

 die;

不知道可能是什么问题。

先谢谢您。

最诚挚的问候！

从打印（写入文件...）开始，您的程序实际生成的输出...显然是无效的XML。请记住，XML比HTML严格得多。
