布尔类型属性在WSO2 EI 6.1.1中不起作用

如何解决布尔类型属性在WSO2 EI 6.1.1中不起作用

我正在将 BOOLEAN 类型属性值（请参见代码： delete_all_contacts 属性）传递给在WSO2 EI 6.1.1中不起作用的端点URL。出现错误，例如“ delete_all_contacts'是布尔值必需的参数” 。我认为即使属性类型为BOOLEAN，也总是将其视为“ STRING”类型。请有人帮助我解决此问题吗？

API代码：

<api context="/contactapi" name="ContactAPI" xmlns="http://ws.apache.org/ns/synapse">
        <resource methods="POST" uri-template="/deletecontact?*">
             <inSequence>
          
          <log level="custom">
                <property name="===Delete contacts " value=" API Called===="/>

            </log>
            
            <property  name="delete_all_contacts" expression="get-property('query.param.delete_all_contacts')" scope="default" type="BOOLEAN"/>
            <property expression="get-property('query.param.ids')" name="ids" scope="default" type="STRING"/>
            <property expression="get-property('Sendgrid-Config')" name="SendgridConfig" scope="default" type="OM"/>
            <property description="apiKey" expression="$ctx:SendgridConfig//*[local-name()='apiKey']" name="apiKey" scope="default" type="STRING"/>

            <filter regex="true" source="boolean(get-property('delete_all_contacts'))">

                    <header expression="fn:concat('https://api.sendgrid.com/v3/marketing/contacts','?delete_all_contacts=',get-property('delete_all_contacts'))" name="To" scope="default"/>
                    <log level="custom">
                        <property expression="get-property('To')" name="===To==="/>
                    </log>
                </then>
                <else>
                    <header expression="fn:concat('https://api.sendgrid.com/v3/marketing/contacts','?ids=',get-property('ids'))" name="To" scope="default"/>
                    <log level="custom">

            <property name="HTTP_METHOD" scope="axis2" type="STRING" value="DELETE"/>
            <call>
                <endpoint>

            </log>
        </faultSequence>
    </resource>
</api>

API详细信息：

URL ：http：// localhost：8280 / contactapi / deletecontact？delete_all_contacts = true

方法：删除

错误响应：

{"message":"'delete_all_contacts' is  boolean required param","parameter":"delete_all_contacts"}

解决方法

我尝试了精简版的API，它似乎可以正常工作。

<api xmlns="http://ws.apache.org/ns/synapse" name="ContactAPI" context="/contactapi">
   <resource methods="POST" uri-template="/deletecontact?*">
      <inSequence>
         <log level="custom">
            <property name="===Delete contacts " value=" API Called===="/>
            <property name="===query.param.delete_all_contacts===" expression="get-property('query.param.delete_all_contacts')/"/>
         </log>
         <property name="delete_all_contacts" expression="get-property('query.param.delete_all_contacts')" scope="default" type="BOOLEAN"/>
         <filter source="boolean(get-property('delete_all_contacts'))" regex="true">
            <then>
               <log level="custom">
                  <property name="===Inside===" value="Then"/>
               </log>
            </then>
            <else>
               <log level="custom">
                  <property name="===Inside===" value="Else"/>
               </log>
            </else>
         </filter>
         <respond/>
      </inSequence>
      <outSequence/>
      <faultSequence>
         <log level="custom">
            <property name="===faultSequence" value="Called=="/>
            <property name="ERROR_MESSAGE" expression="get-property('ERROR_MESSAGE')"/>
         </log>
      </faultSequence>
   </resource>
</api>
                        

但是，我注意到您已将资源方法定义为POST，并发送了一个DELETE请求。也许这会引起一些问题。
