问题：访问名称在循环中更改的变量

我也会尝试简化一些事情，以下是我提出的一些改变：

1. 
   在slurp任务中，注册一个变量，比方说
   
slurp_var

   。每个循环中的Ansible都不会覆盖你的变量，每个循环都会在list数组中添加结果
   
slurp_var.results

   （例子如下）。
   


2. 
   打印 - 或处理 - 您的结果，使用
   
with_items

   环。

这是一个修改过的PB来演示结果：





<code>
  ---
hosts: localhost
gather_facts: false
vars:
  packages:
list:
  package_name1:
    url: http://domaine.com/package_name_src1
    dest: file1
  package_name2:
    url: http://domaine.com/package_name_src2
    dest: file2
 
  tasks:
- name: slurp checksum
  slurp:
    src: "/tmp/{{ item.value.dest }}.sha1"
  register:  slurp_var
  with_dict: "{{ packages.list }}"
- name: debug
  debug:
    msg: "sha1: {{ item.content | b64decode }}"
  with_items: "{{ slurp_var.results }}"
</code>
  





演示运行：

需要你注意的一件事是检查

slurp_var

当你试图“啜饮”的文件丢失时，再添加一些

when

你后续任务中的条款..






希望能帮助到你！
