使用Mule esb发送电子邮件

Question

我必须对“已发送”变量进行测试，如果它为false，那么我必须发送电子邮件，这是我的代码：

<http:request-config name="HTTP_Request_Configuration" protocol="HTTPS" host="gist.githubusercontent.com" port="443" doc:name="HTTP Request Configuration"/>
<smtp:gmail-connector name="Gmail" validateConnections="true" doc:name="Gmail"/>
<flow name="push3Flow">
    <quartz:inbound-endpoint jobName="HTTP-Puller-Scheduler" repeatInterval="5000" responseTimeout="10000" doc:name="Quartz" repeatCount="0">
        <quartz:event-generator-job/>
    </quartz:inbound-endpoint>
    <http:request config-ref="HTTP_Request_Configuration" path="Rajeun/b550fe17181610f5c0f0/raw/9cf0940d1b534220a4e50493f42a70e2f4a20584/file.json" method="GET" doc:name="HTTP"/>
    <json:json-to-object-transformer returnClass="java.lang.Object" doc:name="JSON to Object"/>
    <choice doc:name="Choice">
        <when expression="#[(message.payload.sent) &amp;&amp; (message.payload.email != &quot;&quot;)]">
            <logger level="INFO" doc:name="Logger" message="its ok"/>
        </when>
        <otherwise>
            <component doc:name="Java" class="Component1"/>
          <smtp:outbound-endpoint host="smtp.gmail.com" port="587" 
    user="myemail%40gmail.com" password="pass" to= "<Json-email>@gmail.com"
    from="Rajeun" subject="Testing mule" responseTimeout="10000" connector-ref="Gmail" doc:name="Send notification email"/>
        </otherwise>
    </choice>
</flow>

Java类：

import org.mule.api.MuleEventContext;
import org.mule.api.lifecycle.Callable;


public class Component1 implements Callable{


 @Override
 public Object onCall(MuleEventContext eventContext) throws Exception {
  eventContext.getMessage().setPayload("This is email Body ");
  return eventContext.getMessage();
 }

}

我的json文件：

https://gist.githubusercontent.com/Rajeun/b550fe17181610f5c0f0/raw/3f5eaeea955b6eb56bc4715f535fa8bb6d7ab798/file.json

我想做的是从json文件（与我指定的令牌关联的电子邮件）中自动获取电子邮件。 当我尝试这个：

 <smtp:outbound-endpoint host="smtp.gmail.com" port="587" 
        user="myemail%40gmail.com" password="pass" to= "#[payload.email]"
        from="Rajeun" subject="Testing mule" responseTimeout="10000" connector-ref="Gmail" doc:name="Send notification email"/>

它给出了“电子邮件地址”为空我该怎么办？ 先感谢您。

Answer 1

不要使用#[payload.email]使用#[message.payload.email] ，如下所示：

<smtp:outbound-endpoint host="smtp.gmail.com" port="587" 
        user="myemail%40gmail.com" password="pass" to= "#[message.payload.email]"
        from="Rajeun" subject="Testing mule" responseTimeout="10000" connector-ref="Gmail" doc:name="Send notification email"/>

#[payload.email]因为有时有时单独的有效负载会因为任何原因而失败..因此，最好使用#[message.payload.email]

同样，您的表情应该为<when expression="#[message.payload.sent &amp;&amp; message.payload.email != &quot;&quot;]">

编辑版本

<set-variable variableName="email" value="#[message.payload.email]" doc:name="Variable"/>
 <component doc:name="Java" class="Component1"/>
 <smtp:outbound-endpoint host="smtp.gmail.com" port="587" 
            user="myemail%40gmail.com" password="pass" to= "#[flowVars['email']]"
            from="Rajeun" subject="Testing mule" responseTimeout="10000" connector-ref="Gmail" doc:name="Send notification email"/>

在名为email的变量中设置#[message.payload.email] ，然后像上面一样在smtp组件中使用变量email
