我有一个包含文件以及其他文件夹的文件夹。
我在这些文件夹中有一些JSON文件，我需要在所有这些文件夹中将这些文件中的字符串“ logs ”更改为“ LOGINS ”。
我目前能够在主文件夹中的文件中更改此字符串，但无法在子文件夹中进行更改。
即使在子文件夹中，我也能够列出所有文件，但是我不知道如何更改子文件夹中文件的字符串。
这是我当前的剧本：
if (it == StreamState.STOPPED) {
this.stopForeground(false)
}
else if (it == StreamState.STARTED) {
val channelId = "media_playback_channel"
exoNotificationListener = ExoNotificationListener(onNotificationPosted, onNotificationCancelled)
playerNotificationManager = playerNotificationManager ?: PlayerNotificationManager.createWithNotificationChannel(
application.applicationContext,
channelId,
R.string.media_playback_notification,
R.string.media_playback_notification_id,
mcNotificationManager,
exoNotificationListener
)
playerNotificationManager?.setFastForwardIncrementMs(0)
playerNotificationManager?.setRewindIncrementMs(0)
playerNotificationManager?.setUseNavigationActions(false)
// Here I am setting the color which works fine when content is playing.
playerNotificationManager?.setColor(notificationColor)
bindPlayer(playerNotificationManager)
}

find模块能够根据您的指示为您提供文件列表，根据此结果，要对该列表进行操作，您需要register的结果find模块。
- name: Find all files with extension .json under folder and all sub folders
find:
paths: /var/log/conf/login/
patterns: '*.json'
recurse: yes
register: files_to_change
然后，在注册了此文件列表之后，您可以对find模块产生的所有文件创建循环并多次执行相同的步骤。
这可以通过with_items循环来完成：
- name: Replace string in files
replace:
dest: "{{ item.path }}"
regexp: 'logs'
replace: 'LOGINS'
with_items: "{{ files_to_change.files }}"
完整的剧本说明如下：
---
- hosts: localhost
connection: local
tasks:
######
# Mind that this step is just there to make this example relevant,
# I am creating folders, as your users would do, here
######
- name: Creating folders structure
file:
dest: "{{ item }}"
state: directory
with_items:
- /var/log/conf/login/some
- /var/log/conf/login/sub
- /var/log/conf/login/path/to
######
# Mind that this step is just there to make this example relevant,
# I am just creating some JSON files, here, as your users would do
######
- name: Creating file with the content to replace
copy:
dest: "{{ item }}"
content: "The quick brown fox jumps over the lazy logs ;)"
with_items:
- /var/log/conf/login/some/test.json
- /var/log/conf/login/sub/hello.json
- /var/log/conf/login/path/to/file.json
- name: Find all files with extension .json under folder and all sub folders
find:
paths: /var/log/conf/login/
patterns: '*.json'
recurse: yes
register: files_to_change
######
# Mind that this is looping on the result of the find module,
# so it is fully dynamic based on the folders that your end-users might create
######
- name: Replace string in files
replace:
dest: "{{ item.path }}"
regexp: 'logs'
replace: 'LOGINS'
loop_control:
label: "{{ item.path }}"
with_items: "{{ files_to_change.files }}"
- name: Display files content
debug:
msg: "{{ lookup('file', item.path) }}"
loop_control:
label: "{{ item.path }}"
with_items: "{{ files_to_change.files }}"
这将输出：
