"Remotely closed" 当我尝试在 Mule 中使用 HTTPS 发送 REST

Question

我有一个简单的 REST HTTPS GET，它的 uri 是这样的：

https://mytest.test:443/nccpointshop/REST/giftcard/giftcards/list/currency/SEK

在浏览器、Postman 等中与运行完美配合。使用 Mule 3.8 HTTP 我 select 来自 RAML 生成规范的 uri，设置 uri-param 并且我仍然是出现异常：

我附上了我的配置的图片

Answer 1

Mule HTTP 连接器的特点是它总是从关联的配置中添加主机和端口作为 header： headers=[ 主机=correct.host:443

有些系统不允许这样做，它们不接受添加端口（在我们的例子中，端口是在后端系统中动态分配的）。所以，这个请求：https://correct.host:443/nccpointshop/REST/giftcard/giftcards/list/currency/SEK

无效，但这个有效： https://correct.host/nccpointshop/REST/giftcard/giftcards/list/currency/SEK

这很难被注意到和捕捉到，因为 Postman 和 Chrome 都会发送正确的请求。我建议使用其他一些工具，如 SoapUI（我用它注意到了）。但是，有一种方法可以像这样覆盖 header 中 "Host" 的值：

    <http:request config-ref="HTTP_Request_Configuration1" path="/nccpointshop/REST/giftcard/giftcards/list/currency/SEK" method="GET" doc:name="Copy_of_HTTP">
        <http:request-builder>
            <http:header headerName="Host" value="correct.host"/>
        </http:request-builder>
    </http:request>
