ruby-on-rails - 在 Rails 中，如何记录每个传入 HTTP 请求的全部内容？

Question

我正在构建一个与 Rails 后端通信的应用程序，该后端向 Rails 发送请求。它失败了。有没有一种简单的方法可以让 Rails 记录和吐出来控制台每个传入 HTTP 请求的全部内容？

如果有人感觉特别仁慈，您也许可以帮助解决根本原因。使用简单的curl命令就可以正常工作:

$ curl -X POST -d "<person><name>Jack</name></person>" -H "Content-Type: application/xml" http://localhost:3000/people.xml
 <?xml version="1.0" encoding="UTF-8"?>
 <person>
  <created-at type="datetime">2009-11-08T16:36:54Z</created-at>
  <id type="integer">3</id>
  <name>Jack</name>
  <updated-at type="datetime">2009-11-08T16:36:54Z</updated-at>
 </person>

但是当我的应用程序发送请求时，Rails 吐出的错误是:

你最好的选择可能是让前端服务器(apache、nginx等)吐出这些......

或者，如果您想从 Rails 执行此操作，请在 Controller 中使用 request.env，例如如下

logger.info(request.env.inspect)
