Ansible+Flask+jQueryFileUpload 远程文件管理
一.利用Ansible API 2.0对远程主机指定目录内文件的上传,删除,以及解压缩等操作.
核心代码:
AnsibleApi2.py
#!/usr/bin/env python
# -*- coding: utf-8 -*-
#
# this is the Simple Interface package of Ansible2 API

import os
from tempfile import NamedTemporaryFile
from collections import namedtuple

self.host_ok[result._host.get_name()] = result
def v2_runner_on_failed(self, result, *args, **kwargs):

class AnsibleTask(object):

else:

}
self.loader = DataLoader()
# create inventory and pass to var manager
self.hostsFile = NamedTemporaryFile(delete=False)
self.hostsFile.write(targetHost)
self.hostsFile.close()
self.inventory = Inventory(
loader=self.loader,
variable_manager=self.variable_manager,

self.variable_manager.set_inventory(self.inventory)
self.callback = None
def ansiblePlay(self, module_name, module_args):

# run it

try:

stdout_callback=‘default‘,
)
tqm._stdout_callback = self.callback
result = tqm.run(play)
finally:
# print result
if tqm is not None:
tqm.cleanup()
os.remove(self.hostsFile.name)
self.inventory.clear_pattern_cache()
return result
def run_playbook(self, playbook_path):
self.callback = ResultsCollector()

pbex._tqm._stdout_callback = self.callback
return pbex.run() # 返回的结果是数字，不同的结果对应不同的数字

def ansible_command(targetHost, passwd, module_name, module_args):

return ret, ansiTask.get_result()
def ansible_playbook(targetHost, passwd, playbook_yaml):
"""

:param passwd 主机访问密码
:param playbook_yaml yaml任务文件
"""
ansiTask = AnsibleTask(targetHost, passwd)
ret = ansiTask.run_playbook(playbook_yaml)
return ret, ansiTask.get_result()二.利用jQueryFileUpload框架完成文件列表,文件上传,文件删除等操作的Http请求,以及UI展示
主要涉及到:
<script src="http://www.mamicode.com/static/plugins/jQueryFileUpload/vendor/jquery.ui.widget.js"></script> <!-- The Templates plugin is included to render the upload/download listings --> <script src="http://www.mamicode.com/static/plugins/jQueryFileUpload/tmpl.min.js"></script> <!-- blueimp Gallery script --> <script src="http://www.mamicode.com/static/plugins/jQueryFileUpload/jquery.blueimp-gallery.min.js"></script> <!-- The Iframe Transport is required for browsers without support for XHR file uploads --> <script src="http://www.mamicode.com/static/plugins/jQueryFileUpload/jquery.iframe-transport.js"></script> <!-- The basic File Upload plugin --> <script src="http://www.mamicode.com/static/plugins/jQueryFileUpload/jquery.fileupload.js"></script> <!-- The File Upload processing plugin --> <script src="http://www.mamicode.com/static/plugins/jQueryFileUpload/jquery.fileupload-process.js"></script> <!-- The File Upload validation plugin --> <script src="http://www.mamicode.com/static/plugins/jQueryFileUpload/jquery.fileupload-validate.js"></script> <!-- The File Upload user interface plugin --> <script src="http://www.mamicode.com/static/plugins/jQueryFileUpload/jquery.fileupload-ui.js"></script> <!-- The main application script --> <script src="http://www.mamicode.com/static/plugins/jQueryFileUpload/bootstrap.min.js"></script>
当然在form表单提交的时候,你可能会带外数据,那么你可能会用到jQueryFileUpload框架中的绑定事件,
如下：
// Callback for the submit event of each file upload:
// submit: function (e, data) {}, // .bind(‘fileuploadsubmit‘, func);
// Callback for the start of each file upload request:
// send: function (e, data) {}, // .bind(‘fileuploadsend‘, func);
// Callback for successful uploads:
// done: function (e, data) {}, // .bind(‘fileuploaddone‘, func);
// Callback for failed (abort or error) uploads:
// fail: function (e, data) {}, // .bind(‘fileuploadfail‘, func);
// Callback for completed (success, abort or error) requests:
// always: function (e, data) {}, // .bind(‘fileuploadalways‘, func);
// Callback for upload progress events:
// progress: function (e, data) {}, // .bind(‘fileuploadprogress‘, func);
// Callback for global upload progress events:
// progressall: function (e, data) {}, // .bind(‘fileuploadprogressall‘, func);
// Callback for uploads start, equivalent to the global ajaxStart event:
// start: function (e) {}, // .bind(‘fileuploadstart‘, func);
// Callback for uploads stop, equivalent to the global ajaxStop event:
// stop: function (e) {}, // .bind(‘fileuploadstop‘, func);
// Callback for change events of the fileInput(s):
// change: function (e, data) {}, // .bind(‘fileuploadchange‘, func);
// Callback for paste events to the pasteZone(s):
// paste: function (e, data) {}, // .bind(‘fileuploadpaste‘, func);
// Callback for drop events of the dropZone(s):
// drop: function (e, data) {}, // .bind(‘fileuploaddrop‘, func);
// Callback for dragover events of the dropZone(s):
// dragover: function (e) {}, // .bind(‘fileuploaddragover‘, func);
// Callback for the start of each chunk upload request:
// chunksend: function (e, data) {}, // .bind(‘fileuploadchunksend‘, func);
// Callback for successful chunk uploads:
// chunkdone: function (e, data) {}, // .bind(‘fileuploadchunkdone‘, func);
// Callback for failed (abort or error) chunk uploads:
// chunkfail: function (e, data) {}, // .bind(‘fileuploadchunkfail‘, func);
// Callback for completed (success, abort or error) chunk upload requests:
// chunkalways: function (e, data) {}, // .bind(‘fileuploadchunkalways‘, func);三.利用Flask搭建Web服务器,Flask依赖两个外部库：Jinja2模板引擎和Werkzeug WSGI工具集。

当然这只是目前研究开发的项目中很小的一个功能模块,拿出来分享，谢谢.
