Java - HtmlUnit - 无法将 HTML 保存到文件(在某些情况下)

Question

我在 HtmlUnit 中保存响应 HTML 时遇到间歇性问题。

现在，父目录已存在，并且其他一些文件已写入该目录。查看文件名，我没有看到任何明显的危险信号，表明文件名是错误的。

我可以做什么来纠正这个错误？

谢谢

Answer 1

嗯，您完全在最大路径长度之内。异常跟踪显然认为这是路径问题。

我会尝试一些额外的测试来帮助隔离问题。在写入之前检查目录:File.exists()、File.isDirectory()、File.isWritable()。对文件本身进行类似的检查。可能想看看磁盘是否已满。

如果您能获得有关问题根源的更多信息，我们就能解决问题。
