我目前正在学习Flask.
$.ajax()使用jQuery 发送数据后,type='post'服务器端在检查时发出错误request.method.同样的情况发生在type='get'.
错误

package main

func f(a *int){

}
func main(){

Error :: 不能在f的参数中使用a(type [100] int)作为类型*int
我正在使用AWS Glue创建元数据表。
AWS胶履带数据存储路径：s3：// bucket-name /
S3中的存储桶结构就像
??? bucket-name
? ??? pt=2011-10-11-01
? ? ??? file1
| | ??? file2
? ??? pt=2011-10-11-02
? ? ??? file1
? ??? pt=2011-10-10-01
? ? ??? file1
? ??? pt=2011-10-11-10
? ? ??? file1
为此aws爬行器创建4个表。
我的问题是为什么aws胶履带不检测分区？
我想按照--tags中给出的标签顺序在ansible剧本中运行任务
我的剧本
---
- hosts: all
remote_user: root
vars:
file_path: '{{filename}}'
tasks:
- name: Delete user
user:
name: "{{username}}"
state: absent
remove: yes
tags:
- delete_user
- name: Create user
user:
name: "{{username}}"
shell: /bin/bash
groups: "{{groupname}}"
password: "{{ password |password_hash('sha512') }}"
tags:
- create_user
- name: Add ssh key
authorized_key:
user: "{{username}}"
key: "{{lookup('file', 'file_path')}}"
exclusive: yes
tags:
- add_ssh_key
运行Ansible
ansible-playbook createuser.yml --extra-vars "username=hello password=helloworld groupname=something filename=/path/to/filename" --tags=create_user,add_ssh_key,delete_user
预期产量
