小编srg*_*bnd的帖子

有一个在本地运行的网络服务器，我想在 iframe 内有 Keycloak（在另一个域上）登录页面。我在 Keycloak Real Settings > Security Defenses > Headers > Content-Security-Policy 中尝试了以下设置

frame-src 'self' http://127.0.0.1 http://192.168.1.140 http://localhost *.home-life.hub http://trex-macbook.home-life.hub localhost; frame-ancestors 'self'; object-src 'none';

基本上，我将本地 IP 地址和主机名作为frame-src.

登录页面未显示，我在浏览器控制台中收到此错误

Refused to display 'http://keycloak.example.com:8080/auth/realms/master/protocol/openid-connect/auth?client_id=es-openid&response_type=code&redirect_uri=https%3A%2F%2Fkibana.example.com%3A5601%2Fauth%2Fopenid%2Flogin&state=3RV-_nbW-RvmB8EfUwgkJq&scope=profile%20email%20openid' in a frame because an ancestor violates the following Content Security Policy directive: "frame-ancestors 'self'".

我的自定义标题存在

我的服务器和 UI（服务器呈现）代码：

'use strict';

const Hapi = require('@hapi/hapi');

const init = async () => {
  // Run server on all interfaces
  const server = Hapi.server({
    port: 3000, …

我想在Ansible的帮助下创建和配置Amazon EC2机器.现在,我收到以下错误:

fatal: [localhost]: FAILED! => {"changed": false, "failed": true, "msg": "Instance creation failed => InvalidKeyPair.NotFound: The key pair '~/.keys/EC2-Kibi-Enterprise-Deployment.pem' does not exist"}

但是.pem键存在:

$ ls -lh ~/.keys/EC2-Kibi-Enterprise-Deployment.pem 
-r-------- 1 sergey sergey 1.7K Apr  6 09:56 /home/sergey/.keys/EC2-Kibi-Enterprise-Deployment.pem

它创建于欧盟(爱尔兰)地区.

这是我的剧本:

--
- name: Setup servers on Amazon EC2 machines
  hosts: localhost
  gather_facts: no

  tasks:
    - include_vars: group_vars/all/ec2_vars.yml

    ### Create Amazon EC2 instances

      ec2:
        count: "{{ count }}"
        key_name: "{{ key }}"
        region: "{{ region …

我使用以下前端代码导出.csv文档.

HTML

  <form id="tool-export" method="post" action="export/">{% csrf_token %}
    <a id="export-link" class="btn btn-sm btn-primary" href="#">DOWNLOAD</a>
  </form>

JS

  $('#export-link').click(function(e) {
    e.preventDefault();
    var link = $(this);
    var form = link.closest('form');

    var project_id = proj_id.find(":selected").val();
    var input = $('<input>').attr('type', 'hidden').attr('name', 'project_id').val(project_id);
    form.append($(input));

    var project_type = proj_type.val();
    input = $('<input>').attr('type', 'hidden').attr('name', 'project_type').val(project_type);
    form.append($(input));

    form.submit();
  });

出口运作良好,我得到了正确的文件.但是,我也会在点击导出链接后收到您所做的更改可能无法保存的消息.如何禁用此消息？我不想看到它.

Python 2.7.10

我编写了以下代码来测试一个简单的回调函数.

def callback(a, b):
    print('Sum = {0}'.format(a+b))

def main(callback=None):
    print('Add any two digits.')
    if callback != None:
        callback

main(callback(1, 2))

我执行它时收到这个:

Sum = 3
Add any two digits.

为什么Add any two digits之后Sum = 3呢？我想这是因为回调函数首先执行.执行完所有其他代码后如何执行回调函数main()？

我使用Google Drive API 参考中的这个例子来下载文件

def downloadFile(driveService, fileId):
    request = driveService.files().get_media(fileId=fileId)
    fh = io.BytesIO()
    downloader = MediaIoBaseDownload(fh, request)
    done = False
    while done is False:
        status, done = downloader.next_chunk()
        print ("Download %d%%." % int(status.progress() * 100))

我得到错误

我需要自动完成短语.例如,当我搜索"alz痴呆症"时,我想得到"阿尔茨海默氏症的老年痴呆症".

为此,我配置了Edge NGram tokenizer.我在查询体中尝试了两个edge_ngram_analyzer并standard作为分析器.然而,当我试图匹配一个短语时,我无法得到结果.

我究竟做错了什么？

我的查询:

{
  "query":{
    "multi_match":{
      "query":"dementia in alz",
      "type":"phrase",
      "analyzer":"edge_ngram_analyzer",
      "fields":["_all"]
    }
  }
}

我的映射:

...
"type" : {
  "_all" : {
    "analyzer" : "edge_ngram_analyzer",
    "search_analyzer" : "standard"
  },
  "properties" : {
    "field" : {
      "type" : "string",
      "analyzer" : "edge_ngram_analyzer",
      "search_analyzer" : "standard"
    },
...
"settings" : {
  ...
  "analysis" : {
    "filter" : {
      "stem_possessive_filter" : {
        "name" : "possessive_english",
        "type" : …

我按照Celery Django教程,我在示例(add, mul)中看到的任务对我来说非常有用.我做的时候得到了正确的回答res = add.delay(1,2); res.get().

但是*** NotRegistered: u'pipeline.tasks.sayhello'当我尝试执行另一项任务时,我得到了res = sayhello.delay('trex').

如果我这样做,res = sayhello('trex')我只需输入即可得到结果res.但是通过这种方式,我在不使用Celery的情况下执行ornidarly函数.

该任务仅在我在Django shell中运行时才有效 ./manage shell

>>> res = sayhello.delay('trex')
>>> res.get()
u'Hello trex'

所以,问题是我无法执行sayhello任务pipeline/views.py.但我可以执行任务add,并mul从那里.

这是为什么？如何正确运行任务views.py？

错误已完整消息:

[2016-11-11 10:56:09,870: ERROR/MainProcess] Received unregistered task of type u'pipeline.tasks.sayhello'.
The message has been ignored and discarded.

是否可以在Elasticsearch中查询不同路径上的多个嵌套对象？我可以在一个路径上查询一个嵌套对象,但我找不到正确的语法来查询不同路径上的两个对象.

我需要使用如下逻辑查询:

{'query': {
   'bool': {
       'must': [
           'nested': {
               'path': 'Diagnosis',
               'query': {
                   'bool': {
                       'must': [{'match_phrase': {'Diagnosis.Diagnosis': {'query': "epidemia"}}}]
                   }  
               }
           },
           'nested': {
               'path': 'Demographic',
               'query': {
                   'bool': {
                       'must': [{'match_phrase': {'Demographic.Gender': {'query': "female"}}}]
                   }  
               }
           }
       ]
   }
}}

最终目标是对我的PostgreSQL数据库数据进行非规范化(72个表,总共超过1600列),并且能够对其使用布尔查询.

我想为所有DataTables(带滚动插件)列设置静态宽度.

如果我为<th>除一个之外的所有标签设置宽度,它会使列更宽.如果为所有标签设置了宽度,它就不起作用.另外,当我通过开发人员工具进行检查时,我看不到任何<th>宽度的元素400px.该元素具有不同的宽度115px,132px,145px...

这是为什么？如何设置列的确切宽度？

CSS

.big-col {
  width: 400px;
}

JS

var options = {
    "sScrollX": "100%",
    "sScrollXInner": "110%",
    "bScrollCollapse": true,
    "colReorder": true
};

$(document).ready(function() {
    $('#example').dataTable(options);
});

完整示例:http://fiddle.jshell.net/sergibondarenko/o1hoabep/8/

另外,我尝试了columnDefs选项,但没有成功.

 var options = {
    "columnDefs": [
      { "width": "100px", "targets": "_all" }
    ]
 };

确切的列数未知.HTML表是基于服务器端的数据动态构建的.

我在官方教程https://docs.djangoproject.com/en/1.8/intro/reusable-apps/之后构建并安装了我的自定义Django应用程序

安装似乎很成功.
