在我的流程中执行多个 http 请求时套接字挂断

Question

我在 Node-red 中遇到问题，因为在我的流程中我有几个对我的 node-red 中的其他服务的 http 请求。据我所知，当我对同一个域进行第二次调用时，错误总是出现（即：本地主机，尽管它可能与另一个域有关）

总结：我有 2 个不同的流程：

一个作为从那里检索文件的 gitlab 接口。所以从这里我调用 gitlab 服务器 (Flow 1)
我的另一个应用程序需要检索 2 个不同的文件。从这个流程，我调用了 2 次到之前的流程 (Flow 2)

所以，一旦我的第二个流程开始，在一些 JavaScript 和切换节点之后，我第一次调用到第一个流程，它调用 gitlab。这绝对没问题第二个流程继续并在另一个 JavaScript 个节点之后再次调用第一个流程，似乎流程已冻结并且没有任何反应，2 分钟后我收到此错误：

您知道可能是什么错误吗？

我在网上搜索过nodejs中的这个错误，例如：

Node.js POST causes [Error: socket hang up] code: 'ECONNRESET' Node js ECONNRESET 我一直在本地测试其中一些可能的解决方案（修改库 follow-redirects 和节点 21-httprequest.js）但是没有任何成功，所以我不知道为什么会出现这个错误

我也试过设置延迟，只是为了确保这不是时间问题

我正在使用 node-red v0.16.2 和 nodejs v4.4.3

提前致谢，问候

PS：我已经完成了一项活动指标测试：

Answer 1

当您在同一流中有两个 HTTP Request 节点时，您必须确保在将消息传递给第二个节点之前删除第一个节点返回的 msg.headers 属性。这是因为来自第一个节点的 headers 是响应 headers，通过将它们传递给第二个节点，您要求该节点在发出请求时使用这些 headers。

您还应该使用“调试”节点来查看流到达的位置；您对 gitlab_interface 流的第二次调用挂起 - 在该流中的每个节点之后添加调试节点会告诉您流到达的位置。
