通过 HTTPs 使用 REST 服务时出错

Question

我有一个简单的 REST HTTPS POST，它的 uri 是这样的：https://paymentservicestest.informa.com/mcas_services.asp?

非常适合在浏览器、邮递员等中运行。使用 Mule 3.8 HTTP，我从 RAML 生成规范中选择 uri，设置 uri-param，但我仍然收到异常和下面的代码。

 ERROR 2016-10-11 16:16:52,944 [[tstconnection].HTTP_Listener_Configuration.worker.01] org.mule.module.http.internal.request.DefaultHttpRequester: Remote host closed connection.

Answer 1

您的 URI 中似乎有错字

我可以从您的帖子中看到实际的 URI 应该是：

https://paymentservices.informa.com/

在您的配置中，您正在调用以下 URI：

https://paymentservice.informa.com/

确保在“服务”中包含“s”，这至少应该向正确的服务器发出成功的请求。

将您的 HTTP_Request_Configuration 更改为：

<?xml version="1.0" encoding="UTF-8"?>
 
 <mule
...

<http:request-config name="HTTP_Request_Configuration" protocol="HTTPS" host="paymentservices.informa.com" port="443" connectionIdleTimeout="300000" responseTimeout="300000" doc:name="HTTP Request Configuration" />
...

 </mule>
