WSO2 ESB - REST API - 响应不来 [英] WSO2 ESB - REST API - Response Does Not Come

问题描述

我在 wso2 esb 中使用 公开了一个 REST 服务.但回应并没有到来.REST 服务是用 Apache Wink 编写的.

I have exposed a REST service using <api> in wso2 esb. But the response does not come. REST service is written in Apache Wink.

API

<api name="API_2" context="/hello" hostname="localhost" port="8080">
  <resource url-mapping="/name" methods="GET">
    <inSequence>    
      <log level="full"/>
      <property name="messageType" value="text/plain" scope="transport" type="STRING"/>             
      <send>
        <endpoint>                              
          <address uri="http://localhost:8080/HelloService/rest/test/hello"/>
        </endpoint>
      </send>
    </inSequence>
    <outSequence>
      <log level="full"/>
      <send/>
    </outSequence>
  </resource>   
</api>

esb 日志

推荐答案

我觉得你的端点地址有误，看起来你重复了两次.因为您在代理名称中有 hello 也将附加到 URL.

I think your endpoint address is wrong , look like you have repeat hello twice. since you have hello in proxy name also which will append to URL.

尝试

您也可以通过在单独的浏览器中调用uri + url-mapping"来验证您的后端工作

Also You can verify your backend works by calling "uri + url-mapping" in separate browser

我在下面展示了适用于我的示例 API，您应该如下调用您的 API，并且日志将打印如下.

I have shown sample API works for me below, you should have called your API as below and log will print as below.

调用网址:http://localhost:8280/TestAPI/customerservice/customers/123

信息 - LogMediator 到:/TestAPI/customerservice/customers/123

INFO - LogMediator To: /TestAPI/customerservice/customers/123

    <api xmlns="http://ws.apache.org/ns/synapse" name="TestAPI" context="/TestAPI">
   <resource methods="GET" url-mapping="/customerservice/customers/123">
      <inSequence>
         <log/>
         <send>
            <endpoint>
               <address uri="http://localhost:9764/jaxrs_basic/services/customers"/>
            </endpoint>
         </send>
      </inSequence>
      <outSequence>
         <log/>
         <send/>
      </outSequence>
   </resource>
</api>
