web-services - 如何使用名称/值对创建 HTTP POST 的 Mule ESB 服务？

Question

我需要创建一个 mule 服务，它将数据 POST 到需要名称/值对(而不是 xml)的 Web 服务，然后处理来自该服务的 XML 响应。我找不到关于如何为 http POST 准备有效负载的好示例。

有人可以提供一些见解或示例吗？

到目前为止我所拥有的是(我不知道是否需要“PathToTransformerClass”):

    <service name="myService">
        <inbound>
            <vm:inbound-endpoint path="myService.request" synchronous="true">
                <custom-transformer class="PathToTransformerClass" />
            </vm:inbound-endpoint>
        </inbound>
        <outbound>
            <pass-through-router>
                <http:outbound-endpoint address="URIofWebServiceToPostTo" method="POST" synchronous="true">
                    <response-transformers>
                        <custom-transformer class="PathToClassToProcessTheResponse" />
                    </response-transformers>
                </http:outbound-endpoint>
            </pass-through-router>
        </outbound>
    </service>

我也找不到任何示例，但看起来像是内置的 HTTP transformers是

http-response-to-object-transformer A transformer that converts an HTTP response to a Mule Message. The payload may be a String, stream, or byte array.

http-response-to-string-transformer Converts an HTTP response payload into a string. The headers of the response will be preserved on the message.

object-to-http-request-transformer This transformer will create a valid HTTP request using the current message and any HTTP headers set on the current message.

message-to-http-response-transformer This transformer will create a valid HTTP response using the current message and any HTTP headers set on the current message.

对象到http-request-transformer可能是你最好的选择；也许您可以创建一个键值对映射，然后将其转换为 URL 编码形式？不确定，但希望这能为您提供一些有关 Google 的信息。
