wso2esb-访问迭代器调解器之外的变量 [英] wso2esb- accessing variable outside iterator mediator

问题描述

基本上，在迭代器内部，我正在使用脚本(名称:setValue)中介器设置一些变量.我试图在迭代器外的 Ruby 脚本中访问它们.

Basically, inside iterator, I am setting some variable using Script (name: setValue) mediator. I am trying to access them in the Ruby script outside the iterator.

根据文档:如何访问迭代器内部定义的迭代器外部的属性中介?

我尝试过的不同选项:

1) 在 Ruby 脚本中，我尝试使用

1) In Ruby script, I tried using

$mc.get-property('Operation','githubhosturl1');  I am getting syntax error at operation.

2) 在 Iterator 之外，我尝试使用 Property 访问它们

2) Outside Iterator I tried accessing them using Property

<property   expression="get-property('operation','githubhosturl')  name="githubhosturl1) 

在表达式中出错.

3) 在我尝试过的 Ruby 脚本中:

3) In Ruby script I tried:

$mc.get-property('githubhosturl1') - 返回空值

$mc.get-property('githubhosturl1') - Empty value returning

我该如何解决这个问题?

How can I solve this issue?

我的代码 - 代理服务 - 我只粘贴了有问题的一小部分.在 setValue 脚本中，我可以在控制台日志中打印值.

My code - proxy service - I am pasting only small portion, where there is an issue. In setValue script I am able to print the value in the console log.

推荐答案

通过将 Iteration 内的所有范围从default"更改为Operation"并使用 get-property('operation', variable) 在外部访问它们，然后将范围更改为默认"

By changing all the scope inside the Iteration from "default" to "Operation" and access them outside using get-property('operation', variable) and then change the scope to "Default"
