【问题描述】：

我们将 Quickbooks Web 连接器 (QBWC) 与 Consolibyte Quickbooks php 开发工具包一起使用。我们已经在 QBWC 工作了 4 年，使用该软件没有出现重大问题；但是，现在我们添加了一个额外的 QBWC 作业来访问不同的 QB 公司文件和不同的处理程序。每次运行此作业时都会收到错误“响应不是格式正确的 XML”：

20211117.18:47:19 UTC   : QBWebConnector.RegistryManager.getUpdateLock() : HKEY_CURRENT_USER\Software\Intuit\QBWebConnector\UpdateLock = FALSE

20211117.18:47:21 UTC   : QBWebConnector.SOAPWebService.do_authenticate() : QBWC1012: Authentication failed due to following error message.
Response is not well-formed XML.

错误从 serverVersion() 开始，但直到 authenticate() 作业才真正失败。似乎问题出在 PHP 处理程序中；但是，它没有记录任何错误，并且开发工具包日志表显示了正确的 XML：

我不明白的是，PHP 处理程序对 serverVersion() 的 XML 响应看起来不错（实际上与工作处理程序返回的 XML 相同，但 URL 除外），并且此处理程序没有记录任何错误，但 QBWC正在拒绝它。

【问题讨论】：

我们可能没有足够的信息来诊断，但读取 *** Calling clientVersion() with following parameter:<productVersion="2.2.0.71"> 的日志行要么是错误的日志语法选择，要么是您的 XML 格式不正确问题的线索。

感谢您的回复，虽然这只是日志语法而不是问题的根源。

不客气。很高兴你figured it out。 ??????

【参考方案1】：

已解决 - 对 QBWC 的 XML 响应在 XML 声明之前有一个额外的换行符，这导致 QBWC 完全拒绝它。额外字符的来源是一个 PHP 配置文件，在第一个 <?php 标记之前有一个空行。呵呵！
