Accessing IPv6 resolvable URL with port (e.g. localhost:12345) results in Bad Address in Strawberry Perl 5.30.1

由 旧时模样 提交于 2021-02-07 16:22:05
问题 When using strawberry perl 5.30.1 under Windows 10 with IPv6 enabled, URLs with Portnumbers cannot be resolved properly due to what appears to be a bug in the DNS parser of Perl. For the following test, we have a simple webserver listening on Port 8810 for all interfaces. Port 12345 does NOT host anything. Following is the script we use for reproduction: use strict; use warnings; use LWP::UserAgent; my $ua = LWP::UserAgent->new(); my $result=$ua->get("http://localhost:8810/"); print "(DNS

Perl “lwp-request” giving error 500 using TLS 1.2

问题 We've been using a shipping API via our Unix server, specifically SCO Openserver 5.0.7, for a little over a year. Our system generates XML files, sends them to the server using the lwp-request command, receives the response, interprets it, and processes it as needed by our system. The exact command we use is: lwp-request -m POST https://url.com < REQUESTFILE.XML > RESPONSEFILE.XML The shipping company is upgrading all servers to require TLS 1.2, and now I get 500 SSL negotiation failed: as a

Java线程与Linux内核线程的映射关系

由 こ雲淡風輕ζ 提交于 2020-04-12 09:26:08
Linux从内核2.6开始使用NPTL （Native POSIX Thread Library）支持，但这时线程本质上还是轻量级进程（LWP）。 Java里的线程是由JVM来管理的，它如何对应到操作系统的线程是由JVM的实现来确定的。Linux 2.6上的HotSpot使用了NPTL机制， JVM线程跟内核轻量级进程有一一对应的关系 。线程的调度完全交给了操作系统内核，当然jvm还保留一些策略足以影响到其内部的线程调度，举个例子，在linux下，只要一个Thread.run就会调用一个fork产生一个线程。 Java线程在Windows及Linux平台上的实现方式，现在看来，是内核线程的实现方式。 这种方式实现的线程，是直接由操作系统内核支持的——由内核完成线程切换，内核通过操纵调度器（Thread Scheduler）实现线程调度，并将线程任务反映到各个处理器上。 内核线程是内核的一个分身。程序一般不直接使用该内核线程，而是使用其高级接口，即轻量级进程（LWP），也即线程。这看起来可能很拗口。看图： （说明：KLT即内核线程Kernel Thread，是“内核分身”。每一个KLT对应到进程P中的某一个轻量级进程LWP（也即线程），期间要经过用户态、内核态的切换，并在Thread Scheduler 下反应到处理器CPU上。） 这种线程实现的方式也有它的缺陷

How can I update my Twitter status with Perl and only LWP::UserAgent?

问题 I'm trying to update my status through the Twitter API and OAuth. I get stuck on the last step, the status update. Here's my code.

How can I make a JSON POST request with LWP?

问题 If you try to login at https://orbit.theplanet.com/Login.aspx?url=/Default.aspx (use any username/password combination), you can see that the login credentials are sent as a non-traditional set of POST data: just a lonesome JSON string and no normal key=value pair. Specifically, instead of: username=foo&password=bar or even something like: json={"username":"foo","password":"bar"} There's simply: {"username":"foo","password":"bar"} Is it possible to perform such a request with LWP or an
