我正在使用html和jquery mobile.here代码:

<div data-role = "content">
        <form action = "?" method="post" name="form" id = "form">
            <fieldset>
            <div data-role = "fieldcontain" class = "ui-hide-label">
                <label for="name">Name</label>
                <input type="text" name="name" id="name" value="" placeholder="Name" />
            </div>

            <div data-role ="fieldcontain" class= "ui-hide-label">
                <label for="surname">Surname</label>
                <input type="text" name="surname" id="surname" value="" placeholder="Surname"/>
            </div>

            <div data-role ="fieldcontain" class= "ui-hide-label">
                <label for="address">Address</label>
                <input type="text" name="address" id="address" value="" placeholder="Address"/>
            </div>


                <div data-role="fieldcontain" class="ui-hide-label">
                    <label for="birth-place">Birth Place</label>
                    <input type="text" name="birth-place" id="birth_place" value="" placeholder="Birth Place" />
                </div>
                <div data-role = "fieldcontain" …

我正试图通过名为Wreck的节点模块获取html页面

获取数据应该很容易,但我无法得到它们

'use strict';

var Wreck = require('wreck');

var url = 'http://www.google.it';

var callback = function(err, response, payload){
  Wreck.read(response, null, function(err, body){
      //here print out the html page
  });
};

Wreck.get(url, callback);

上面是一个简单的脚本,只是开发人员自述文件的副本.根据文档body应该返回一个缓冲对象,但我怎样才能读取一个body对象？我已阅读使用toJSON或toString()但我没有得到任何结果

创建一个线程并在类的构造函数中调用其start()方法是否正确？

public class Server implements Runnable {

    private ServerSocket server;

    public Server(int port) {
        try {
            //Opens a new server 
            server = new ServerSocket(port);
        } catch (IOException ioe) {
            ioe.printStackTrace();
        }

        new Thread(this, "Server").start();
    }

    @Override
    public void run() {
    }
}

我正在寻找验证用户登录属于角色的功能.可能是以下几点？

pageContext.request.userPrincipal.roles 

我应该如何与JSTL一起正确使用它来测试用户是否属于ADMIN组？

这有什么错误？

我正在尝试使用以下代码更新实体:

db.Account.update({
                    'post_id': data.id
                }, {
                  where: { id: account.id }
                })
                .spread(account => {

                  next();
                });

但它不起作用.任何的想法？

我有以下两个bash行

TMPFILE="$(mktemp)" || exit 1

< package.json jq '. + {"foo":'"${BOO}"'}' > "$TMPFILE"

但是我收到以下错误:

jq: error: syntax error, unexpected '}' (Unix shell quoting issues?) at <top-level>, line 1:
. + {"foo":}
jq: 1 compile error

任何想法如何通过在那里使用双引号来使shellcheck错误静音来正确地逃避该部分

我正在尝试使用包在 python 中构建 CLI click。我使用的 Python 版本是3.6

这是我的应用程序的主要内容：

import os
import click

cmd_folder = os.path.join(os.path.dirname(__file__), 'commands')


class IAMCLI(click.MultiCommand):

    def list_commands(self, ctx):
        rv = []
        for filename in os.listdir(cmd_folder):
            if filename.endswith('.py') and \
                    filename.startswith('cmd_'):
                rv.append(filename[4:-3])
        rv.sort()
        return rv

    def get_command(self, ctx, cmd_name):
        ns = {}
        fn = os.path.join(cmd_folder, 'cmd_{}.py'.format(cmd_name))
        with open(fn) as f:
            code = compile(f.read(), fn, 'exec')
            eval(code, ns, ns)
        return ns['cli']


@click.command(cls=IAMCLI)
@click.option('--env', default='dev', type=click.Choice(['dev', 'staging', 'production']),
              help='AWS Environment')
@click.pass_context
def cli():

嗨,我想创建一个数组,其中每个位置由枚举的值表示.

例如:

public enum type{

  green,blue,black,gray;

}

现在我想创建一个阵列,其中每个位置都是绿色,蓝色,......

我会更清楚.我想创建一个数组,其中位置由enum class.instead int []数组表示.[=] int []创建int [] array = new int [type.value]

我已将gson添加到我的pom.xml。就这个。但是当我打电话Gson gson = new Gson()并尝试在 Maven 存储库中搜索时，它没有找到任何元素。为什么？我哪里错了？

在 docker-compose 中，我用这种方式创建卷：

volumes:
  - ./server:/home/app
  - /home/app/node_modules

为了解决 的问题node_modules。

我该如何解决 kubernetes 中的问题？

我创建了以下配置

  spec:
    containers:
    - env: []
      image: "image"
      volumeMounts:
      - mountPath: /home/app
        name: vol-app
      - mountPath: /home/app/node_modules
        name: vol-node-modules
      name: demo
    volumes:
    - name: vol-app
      hostPath:
        path: /Users/me/server
    - name: vol-node-modules
      emptyDir: {}

但它不起作用。节点模块为空
