Question

我正在尝试检查服务器上是否存在多个HTTP资源，以及他们何时不想上传它们。问题是我不知道如何注册多个

- name: Checking if schema already exists
  uri:
    url: http://{{ riak_server }}:10018/search/schema/{{ item }} return_content=yes
  register: http_response_{{ item }}
  failed_when: http_response_{{ item }}.status != 400
  with_items:
    - sch_patents
    - sch_entities
    - sch_cpcs
    - sch_ipcs
    - sch_entities_patents
  run_once: true
  delegate_to: "{{ riak_server }}"
  tags: creating_schema

调用任务失败：

TASK: [riak | Checking if schema already exists] ******************************
fatal: [10.10.10.11 -> 10.10.10.11] => error while evaluating conditional: http_response_sch_patents.status != 400

FATAL: all hosts have already failed -- aborting

检查多个资源并上传丢失的资源的正确方法是什么？

当从循环任务中注册输出时（例如使用with_items时），您将从所有循环变量中获得响应的字典。

所以你应该做这样的事情：

- name: Checking if schema already exists
  uri:
    url: http://{{ riak_server }}:10018/search/schema/{{ item }} return_content=yes
  register: http_responses
  with_items:
    - sch_patents
    - sch_entities
    - sch_cpcs
    - sch_ipcs
    - sch_entities_patents
  run_once: true
  delegate_to: "{{ riak_server }}"
  tags: creating_schema

- name: copy schema if not exists
  copy:
    src: path/to/src/schema
    dest: path/to/dest/
  when: {{ item.status }} != 400
  with_items: http_responses.results

使用Ansible检查HTTP资源的最佳方法是什么？
