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:

            ]
        )
        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):

    """
    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。
