我对ansible数组有问题。

我有一个像这样的任务：

  tasks:   
  - name: create member and add to pool 
    bigip_pool_member:
      pool: "{{pool_name}}"
      partition: "{{partition}}"
      host: "{{ip}}"
      name: "{{ip}}"
      port: "{{port}}"
      monitors:
        - "{{item}}"
      loop: "{{monitor}}"
      description: "{{description_member}}" 
      provider:
               ####

我想将多个监视器添加到池中。只有它不起作用。我需要完成一项任务。我该怎么做？
