Question

我有一个非常奇怪的问题，当我尝试使用RestClient访问URL时，它会超时。如果我直接从shell访问URL（使用curl），它加载正常。我可以通过RestClient访问其他网址，例如google。

此外，如果我直接使用Net :: HTTP并发送GET请求，它会通过（!!）。

我怀疑RestClient没有正确构建请求，但我不确定如何让RestClient注销掉任何有用的东西。我也不知道如何访问它正在生成的请求。

如何查看RestClient正在进行的完整http请求？

以下是一些概述问题的代码：

谢谢！

由于错误日志中引用了一些代码行，特别是一个救援块（/lib/restclient/request.rb:427:in＆＃39; rescue in transmission＆＃39;），你可以打开gem并在这些方法中添加一些日志/放置/语句，以尝试找出挂起的链中的哪个位置。它不是超级手术，但它可以让你朝着正确的方向前进。如果您使用的是bundler，我相信您可以运行bundle open restclient，然后深入了解gem的源代码。

如何检查/调试/查看由RestClient生成的请求？
