NodeJS http-proxy-middleware 停止转发

如何解决NodeJS http-proxy-middleware 停止转发

我是 Node 的新手，尤其是 http-proxy-middleware，所以我不确定要提供多少信息以及提供哪些信息。我的中间件服务器过去常常接受请求并将它们转发到另一个 Java 服务器并向原始调用者提供响应。但是，它不再转发到 Java 服务器。不过，Java 服务器确实会响应直接请求。我相信这与我们将 Java 服务器从 HTTPS 服务器更改为 HTTP 相关，因为这是更改的关键。然而，我想我告诉了代理中间件它需要的一切。

我通过 DEBUG=express-http-proxy 启用了调试

我的中间件托管在 https://localhost:8080，关键 URI 是 /sprint-cost-recovery。

我的日志显示：

config.sprint_cost_recovery_client_host=http://localhost:8447 config.sprint_cost_recovery_server_host=http://localhost:8448

我的路由片段是：

    app.use('/sprint-cost-recovery*',ensureAuthenticated,function (req,res,next) {
            logger.debug('Route: /sprint-cost-recovery: Forwarding to '+config.sprint_cost_recovery_client_host);
            next();
        },forward_proxy(config.sprint_cost_recovery_client_host,{
            limit: '2mb',memoizeHost: false,preserveHostHdr: true,https: false,secure: false,proxyErrorHandler: function (err,next) {
                util.inspect(err);
                next();
            },proxyReqPathResolver: req => {
                logger.debug('Route: /sprint-cost-recovery: proxyReqPathResolver() function reached');
                util.inspect(req.originalUrl);
                util.inspect(req.hostname);
                util.inspect(req.https_port);
                const result = url.parse(req.originalUrl).path;
                logger.debug('Route: /sprint-cost-recovery: proxyReqPathResolver(): result=' + result);
                return result;
            }
        })
    );

我愿意接受猜测。顺便说一句，有谁知道是否有用 Java 编写的中间件/表达等价物？
