c++ - LibJingle pcp_main.cc 503 错误

几天来，我一直在努力让 PCP LibJingle 示例发挥作用。在解决了所有编译和运行错误之后，我现在遇到了一个我以前没有遇到过的错误。

当作为发送方或接收方运行程序时，程序会收到 503“服务不可用”错误并终止程序，但作为服务器运行时工作正常。我知道标准是 5xx 表示服务器端错误，所以我逐行查看程序输出(最后提供)。根据我对服务器和 LibJingle 几乎为零的经验，我能想到的最好的结果是以下任一(或两者)导致 503:

  1. Google 已禁用 LibJingle pcp 示例的必要服务。
  2. 优先级状态 = -1(据我所知，意味着客户端不可用)。

我已经登录了这两个 Google 帐户，因此它们不会离线/不可用，LibJingle 程序反射(reflect)了这一点。但是，一旦 PCP 示例运行，优先级就会设置回 -1。我还注意到程序输出中的大部分(如果不是全部的话)Google 链接都是 404。

我的问题:

  • 这些理论是否接近于可能/正在发生的事情？
  • 我需要做什么来解决这个问题？
  • 我听说可以使用服务器(Google 服务器以外的服务器)来运行该程序。这是真的？如果是这样，我应该去哪里调查？

提前感谢您的帮助。--KMC

附言在提供的程序输出中，我试图将文件从 forge...1@gmail.com 发送到 forge...2@gmail.com。我审查了一些内容并试图减少其他内容。但是，由于不确定什么可能相关或不相关，我没有做太多剪辑。如果 mod 或其他人知道可能相关的内容并想对其进行编辑，请随时进行。

编辑:根据要求，我包含了一些代码(我会包含所有代码，但主文件有 723 行)。我仍然直接使用未修改的 Google 的 LibJingle 代码，因为我还没有能够让它工作。可以找到此文件的完整代码 here .

最佳答案

好的，所以这个错误是因为错误的完整 JID 和错误的代码执行。 PCP 应按照提供的顺序运行:

  1. 运行“./pcp receiveruser@host.com”并提供帐户密码。
  2. 读取代码输出中提供的 receiveruser@host.com 帐户的完整 JID。如果可能，最简单的方法是在输出中搜索:“logged in as”。取用户账户信息中“.com/”后的所有内容。
  3. 运行“./pcp senderuser@host.com send_file_name.extension receiveruser@host.com/(full JID):received_file_name.extension”

发生此错误是因为正在使用的代码执行方法阻止了帐户被视为可用。这与服务器错误或缺少谷歌服务无关(很抱歉怀疑你，谷歌)。至于优先级为 -1，这也与错误无关(在阅读 XMPP 后了解到)。
