WSO2のREST APIで空のレスポンスを返すESB

Question

WSO2のESB 4.9.0にAPIアーティファクトがあり、単純なPUT RESTサービスを提供しています。

PUTサービスはここで着信要求のログを簡略化し、コンテンツなしでHTTPコード200で応答する必要があります。

これは、APIのリソースです：私は、次の例外を取得（GET要求で使用されている）をtrueにプロパティ "NO_ENTITY_BODY" と

<api xmlns="http://ws.apache.org/ns/synapse" name="myapi" context="/context"> 
    <resource methods="PUT" uri-template="/resource"> 
     <inSequence> 
      <log level="custom"> 
       <property name="PUT" value="/v1/updateWorkflowData" /> 
      </log> 
      <property name="NO_ENTITY_BODY" value="true" scope="axis2" /> 
      <property name="HTTP_SC" value="200" scope="axis2" /> 
      <respond /> 
     </inSequence> 
    </resource> 
</api>

私の質問は現在：

1. 一般：リクエストにコンテンツが含まれている場合、レスポンスを空に設定するにはどうすればよいですか？
2. "NO_ENTITY_BODY"のソリューションは間違っていて動作しませんか？

Answer 1

1）スクリプトメディエータを使用して、応答本文を空の文字列に置き換えることができます。これを行う他の方法もあります。スクリプトメディエーターはオプションです。

2）"NO_ENTITY_BODY「あなたは体を持っていない要求からの応答を期待することを指定するために使用されている。例えばGETリクエスト。

Answer 2

NO_ENTITY_BODYあなたはtype属性を追加する必要がありますので、ブール値になることを期待：

<property name="NO_ENTITY_BODY" value="true" scope="axis2" type="BOOLEAN" />
