我的代码如下:
URL url = new URL("1.0.0.25/otfg/services");
HttpURLConnection cnx = url.openConnection();
cnx.setRequestProperty("Host", "example.org");
但是当我使用 tcpdump 记录传出的包时,http-header "Host" 是 1.0.0.25.
But when I log the outgoing packages with tcpdump the http-header "Host" is 1.0.0.25.
可能是http-header主机"在发送过程的后期被覆盖,如果是,我该如何避免这种行为.
Could it be that the http-header "Host" is overwritten at a later stage of the sending process, if yes how can I avoid this behavior.
重复问题.
最后一条评论解决了我的问题:
The last comment solved my problem:
System.setProperty("sun.net.http.allowRestrictedHeaders", "true")
或者在虚拟机启动时:
-Dsun.net.http.allowRestrictedHeaders=true
这篇关于如何覆盖 http-header “主机"在 HttpURLConnection 中?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持跟版网!
