Quickbooks Web 连接器 "Response is not well-formed XML" 错误

Question

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 工作中使用该软件 4 年，没有出现重大问题；但是，现在我们正在添加一个额外的 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出现错误“响应格式不正确 XML”：

Response is not well-formed XML.

错误从 serverVersion() 开始，但作业实际上并没有失败，直到 authenticate()。看来问题出在 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 table 显示正确的 XML:

我不明白的是 PHP 处理程序对 serverVersion() 的 XML 响应看起来很好（实际上与工作处理程序返回的 XML 相同，除了URL)，并且此处理程序未记录任何错误，但 QBWC 拒绝它。

Answer 1

已解决 - XML 对 QBWC 的响应在 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。呸！
