我在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下载这些软件包。以下是方法：
---
- 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，但是在第二个任务中，出现以下错误：
[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.
您必须from_json在查找后添加jinja2过滤器：
version_file: "{{ lookup('file','/home/shasha/devOps/tests/packageFile.json') | from_json }}"
