如何在ansible中遍历字典值

我试图遍历“ key”：＆“ Value”的字典。我没有得到适当的结果。我想从字典中打印某些键的值。

这是我的代码：

- hosts: all
  gather_facts: false
  strategy: free
  tasks:
  - include_vars: roles/oracle/vars/install_vars.yaml
    vars:
     var_list:
        - script_name

  - set_fact:
      ORACLE_HOMES_DIR: "/u01/app/oracle/product"
      DB_HOME: "{{ ORACLE_HOMES_DIR }}/{{ ORACLE_VERSION }}/dbinst_1"

  - name: Copy script to host
    copy:
      src: "{{ playbook_dir }}/{{ script_name }}"
      dest: "/tmp/"
      owner: "{{ USER_ORACLE }}"
      group: "{{ GROUP_ORACLE }}"
      mode: 0755

  - name: Verify if the DB is open READ WRITE (or) not
    become_user: "{{ USER_ORACLE }}"
    environment:
      ORACLE_SID: "{{ sid }}"
      ORACLE_HOME: "{{ ORACLE_HOME }}"
    shell: "echo \"set pagesize 0\n select trim(open_mode) from v\\$database;\" | {{ORACLE_HOME}}/bin/sqlplus -S / as sysdba"
    with_items: "{{ hostvars[inventory_hostname]['sid_list'] }}"
    loop_control:
      loop_var: sid
    register: om

  - name: Get the OM output
    debug:
     msg: "om Results {{ item.0.sid }} is {{ item.1.value }}"
    with_dict: "{{ om.results }}"
    when: ("'sid' in item.key" and "'stdout' in item.key")

我试图在此处打印键“ sid”和“ stdout”的所有值，以下是字典的输出。因此，我可以使用循环条件遍历所有处于“读取写入”模式的SID的运行SQL查询。

答案 0 :(得分：0)

据我所知，您正在寻找sid包含om.results[].stdout的{​​{1}}吗？如果是这样，READ WRITE肯定是错误的解决方法，因为with_dict:是列表而不是 dict ；您想要的是：

om.results
