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 # # Author: TCollaboration # import os from tempfile import NamedTemporaryFile from collections import namedtuple from ansible.parsing.dataloader import DataLoader from ansible.vars import VariableManager from ansible.inventory import Inventory from ansible.playbook.play import Play from ansible.executor.playbook_executor import PlaybookExecutor from ansible.executor.task_queue_manager import TaskQueueManager from ansible.plugins.callback import CallbackBase class ResultsCollector(CallbackBase): def __init__(self, *args, **kwargs): super(ResultsCollector, self).__init__(*args, **kwargs) self.host_ok = {} self.host_unreachable = {} self.host_failed = {} def v2_runner_on_unreachable(self, result): self.host_unreachable[result._host.get_name()] = result def v2_runner_on_ok(self, result, *args, **kwargs): self.host_ok[result._host.get_name()] = result def v2_runner_on_failed(self, result, *args, **kwargs): self.host_failed[result._host.get_name()] = result class AnsibleTask(object): def __init__(self, targetHost, passwd=None): Options = namedtuple(‘Options‘, [‘listtags‘, ‘listtasks‘, ‘listhosts‘, ‘syntax‘, ‘connection‘, ‘module_path‘, ‘forks‘, ‘remote_user‘, ‘private_key_file‘, ‘ssh_common_args‘, ‘ssh_extra_args‘, ‘sftp_extra_args‘, ‘scp_extra_args‘, ‘become‘, ‘become_method‘, ‘become_user‘, ‘verbosity‘, ‘check‘]) # initialize needed objects self.variable_manager = VariableManager() self.options = Options( listtags=False, listtasks=False, listhosts=False, syntax=False, connection=‘smart‘, module_path=‘/usr/lib/python2.7/site-packages/ansible/modules‘, forks=100, remote_user=‘root‘, private_key_file=None, ssh_common_args=None, ssh_extra_args=None, sftp_extra_args=None, scp_extra_args=None, become=False, become_method=None, become_user=‘root‘, verbosity=None, check=False) if not passwd: self.passwords = dict(vault_pass=‘secret‘) else: self.passwords = { ‘conn_pass‘: ‘{0}‘.format(passwd), ‘become_pass‘: ‘{0}‘.format(passwd) } 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, host_list=self.hostsFile.name) self.variable_manager.set_inventory(self.inventory) self.callback = None def ansiblePlay(self, module_name, module_args): # create play with tasks play_source = dict( name="Ansible Play", hosts=‘all‘, gather_facts=‘no‘, tasks=[ dict(action=dict(module=module_name, args=module_args)) ] ) play = Play().load( play_source, variable_manager=self.variable_manager, loader=self.loader) # run it tqm = None self.callback = ResultsCollector() try: tqm = TaskQueueManager( inventory=self.inventory, variable_manager=self.variable_manager, loader=self.loader, options=self.options, passwords=self.passwords, 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 = PlaybookExecutor( playbooks=[playbook_path], inventory=self.inventory, variable_manager=self.variable_manager, loader=self.loader, options=self.options, passwords=self.passwords) 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 get_result(self): self.results_raw = {‘success‘: {}, ‘failed‘: {}, ‘unreachable‘: {}} for host, result in self.callback.host_ok.items(): self.results_raw[‘success‘][host] = result._result for host, result in self.callback.host_failed.items(): self.results_raw[‘failed‘][host] = result._result[‘msg‘] for host, result in self.callback.host_unreachable.items(): self.results_raw[‘unreachable‘][host] = result._result[‘msg‘] return self.results_raw def ansible_command(targetHost, passwd, module_name, module_args): """ ansible 模块接口 :param targetHost 主机ip :param passwd 主机访问密码 :param module_name 模块名称 :param module_args 模块参数 """ ansiTask = AnsibleTask(targetHost, passwd) ret = ansiTask.ansiblePlay(module_name, module_args) return ret, ansiTask.get_result() def ansible_playbook(targetHost, passwd, playbook_yaml): """ ansible playbook接口 :param targetHost 主机ip :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="/static/plugins/jQueryFileUpload/vendor/jquery.ui.widget.js"></script> <!-- The Templates plugin is included to render the upload/download listings --> <script src="/static/plugins/jQueryFileUpload/tmpl.min.js"></script> <!-- blueimp Gallery script --> <script src="/static/plugins/jQueryFileUpload/jquery.blueimp-gallery.min.js"></script> <!-- The Iframe Transport is required for browsers without support for XHR file uploads --> <script src="/static/plugins/jQueryFileUpload/jquery.iframe-transport.js"></script> <!-- The basic File Upload plugin --> <script src="/static/plugins/jQueryFileUpload/jquery.fileupload.js"></script> <!-- The File Upload processing plugin --> <script src="/static/plugins/jQueryFileUpload/jquery.fileupload-process.js"></script> <!-- The File Upload validation plugin --> <script src="/static/plugins/jQueryFileUpload/jquery.fileupload-validate.js"></script> <!-- The File Upload user interface plugin --> <script src="/static/plugins/jQueryFileUpload/jquery.fileupload-ui.js"></script> <!-- The main application script --> <script src="/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.
