我正在尝试通过WSO2 ESB(RESTful API服务集成)创建集成层。

端点 - http://www.thomas-bayer.com/

上下文 - / sqlrest

URI-template - / CUSTOMER / 3

(API端点 - www.thomas-bayer.com/sqlrest/CUSTOMER/3)

当我尝试使用(http://localhost:8280:/sqlrest/CUSTOMER/3

调用api请求时

我的响应是完整的HTML,包含404错误代码,而不是XML数据。

您可以在WSO2 ESB中使用此API:

<?xml version="1.0" encoding="UTF-8"?>
<api xmlns="http://ws.apache.org/ns/synapse"
     name="sqlrestAPI"
     context="/sqlrest">
   <resource methods="GET" protocol="http" uri-template="/CUSTOMER/{id}">
      <inSequence>
         <log level="full"/>
         <send>
            <endpoint>
               <http method="GET"
                     uri-template="http://www.thomas-bayer.com/sqlrest/CUSTOMER/{uri.var.id}"/>
            </endpoint>
         </send>
      </inSequence>
      <outSequence>
         <send/>
      </outSequence>
      <faultSequence/>
   </resource>
</api>

并使用(在我的情况下OFFSET = 3)调用它:

curl -v http://localhost:8283/sqlrest/CUSTOMER/3

回应:

* About to connect() to localhost port 8283 (#0)
*   Trying 127.0.0.1...
* connected

您提供的上下文不需要是实际端点URL中的任何内容。

例如,您可以将上下文定义为myapi。那你有2个选择。

选项1:

将端点配置为http://www.thomas-bayer.com/

然后,您可以将您的API称为http://localhost:8280/myapi/sqlrest/CUSTOMER/3

选项2:

将端点配置为http://www.thomas-bayer.com/sqlrest/

然后,您可以将您的API称为http://localhost:8280/myapi/CUSTOMER/3
