如何打印HttpURLConnection发送的所有请求标头？
[英]How to print all the request headers which HttpURLConnection is sending?
问题描述
I am using HttpURLConnection in one of my Java program to hit a HTTP URL via Java. 
我在我的一个Java程序中使用HttpURLConnection通过Java访问HTTP URL。
I know I can set the request header value something like this. 我知道我可以像这样设置请求标头值。
connObj.setRequestProperty("User-Agent", "curl/7.29"); connObj.setRequestProperty（“ User-Agent”，“ curl / 7.29”）;
But I want to print all the request headers which is generated by URLConnection. 但我想打印所有由URLConnection生成的请求标头。 Is that possible? 那可能吗？

How about calling getRequestProperties() which as the documentation states 如何调用文档中指出的getRequestProperties()
Returns an unmodifiable Map of general request properties for this connection.
