如何使用ansible读取json文件

我的 ansible 脚本所在的目录中有一个 json 文件。以下是json文件的内容：

{ "resources":[
           {"name":"package1", "downloadURL":"path-to-file1" },
           {"name":"package2", "downloadURL": "path-to-file2"}
   ]
}

我正在尝试使用 get_url 下载这些包。下面是方法：

---
- hosts: localhost
  vars:
    package_dir: "/var/opt/"
    version_file: "{{lookup('file','/home/shasha/devOps/tests/packageFile.json')}}"

  tasks:
    - name: Printing the file.
      debug: msg="{{version_file}}"

    - name: Downloading the packages.
      get_url: url="{{item.downloadURL}}" dest="{{package_dir}}" mode=0777
      with_items: version_file.resources

第一个任务是正确打印文件的内容，但在第二个任务中，我收到以下错误：

[DEPRECATION WARNING]: Skipping task due to undefined attribute, in the future this
will be a fatal error.. This feature will be removed in a future release. Deprecation
warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.

你必须添加一个from_jsonjinja2 查找后过滤器：

version_file: "{{ lookup('file','/home/shasha/devOps/tests/packageFile.json') | from_json }}"
