如何在使用Dispatch和Scala时打印http请求
当我使用Dispatch库和Scala时，出于调试目的，如何在写完这样的语句之后用文本中的标题等打印出整个HTTP请求？
When I am using Dispatch library and Scala, for debugging purpose, how to print out the entire HTTP request with headers, etc. in text after writing a statement like this ?
val svc = url("http://api.hostip.info/country.php")
假设您使用的是最新版本的lib， url（...）返回 Req ，这只是 com.ning.http的一个薄包装器.client.RequestBuilder 。您可以使用 svc.toRequest 获取基础请求对象，然后可以调用 toString 或组合其他方法取决于您真正追求的信息。更多信息：
Assuming you're using the latest version of the lib, url(...) returns a Req, which is just a thin wrapper around com.ning.http.client.RequestBuilder. You can get the underlying request object with svc.toRequest, which you can then call toString on or combine the other methods available depending on what information you're really after. More info:
