http - 一些 Camel IN 交换标头未映射到 HTTP 标头，尽管 mapHttpMessageHeaders 和 copyHeaders 都默认为 true

Question

我正在使用 Camel 3.1.0 版及其 http 组件来调用 REST 端点，该端点需要以下标头：日期、主机、摘要、授权等以确保安全。但是，当我在向 http 组件发送请求之前在路由中设置所有这些标头时，总是缺少“日期”HTTP 标头。使用 WireMock 和真实测试环境进行测试。如果我将它与其他几个测试一起运行而不是单独运行，那么测试也可以通过。

这是代码：

        .setHeader("flowId", simple("\${body.flowId}"))
        .process { exchange ->
            with(pubsubConfig) { exchange.setPubsubTimeHeaders(minIntervalValueMills, maxIntervalValueMills, timeoutMillis) }

            val settlementAdviceRequestDto = exchange.message.body as SettlementAdviceRequestDto
            exchange.setProperty("settlementAdviceRequestDto", settlementAdviceRequestDto)

            // Setting security headers
            request.entity = StringEntity(jacksonObjectMapper().writeValueAsString(settlementAdviceRequestDto))
            signer.signRequest(request, exchange.message)
        }
        .marshal(settlementAdviceRequestJacksonDataFormat)
        .logInfoWithBreadCrumbId("Received SettlementAdviceRequestDto from PubSub, flowId: \${header.flowId}, sending to N&TS with \${headers}")
        .to(with(ntsConfigProperties) {
            "$protocol://$host:$port/$path?" +
                    "httpClient.maxConnTotal=$maxConnectionsTotal" +
                    "&httpClient.maxConnPerRoute=$maxConnectionsPerRoute" +
                    "&httpClient.connectionRequestTimeout=$connectionRequestTimeout" +
                    "&httpClient.connectTimeout=$connectionTimeout" +
                    "&httpClient.socketTimeout=$socketTimeout" +
                    "&httpClient.redirectsEnabled=$followRedirects"
        })
        .logInfoWithBreadCrumbId("SettlementAdviceRequestDto sent to N&TS, flowId: \${header.flowId} \${headers}")
