=====================正確答案========================
臥槽，原來是我的阿里云的端口號配置錯(cuò)了

這樣是不行的！

你在window.onload的外面聲明一個(gè)變量var app ,把里面的var去掉就可以了,或則直接把里面的var去掉

原生也可以呢步驟:
下載 npm i -S blueimp-md5;
導(dǎo)入:import md5 from 'blueimp-md5'
普通加密:let val=md5('value');

1. 關(guān)于 pyo 優(yōu)化:

參考鏈接

• When the Python interpreter is invoked with the -O flag, optimized code is generated and stored in .pyo files. The optimizer currently doesn't help much; it only removes assert statements. When -O is used, all bytecode is optimized; .pyc files are ignored and .py files are compiled to optimized bytecode.
• Passing two -O flags to the Python interpreter (-OO) will cause the bytecode compiler to perform optimizations that could in some rare cases result in malfunctioning programs. Currently only __doc__ strings are removed from the bytecode, resulting in more compact .pyo files. Since some programs may rely on having these available, you should only use this option if you know what you're doing.
• Your program doesn't run any faster when it is read from a .pyc or .pyo file than when it is read from a .py file; the only thing that's faster about .pyc or .pyo files is the speed with which they are loaded.
• When a script is run by giving its name on the command line, the bytecode for the script is never written to a .pyc or .pyo file. Thus, the startup time of a script may be reduced by moving most of its code to a module and having a small bootstrap script that imports that module. It is also possible to name a .pyc or .pyo file directly on the command line.

2. 關(guān)于 pyd:

pyd 可以理解為 Windows DLL 文件。

參考鏈接

• Yes, .pyd files are dll’s, but there are a few differences. If you have a DLL named foo.pyd, then it must have a function PyInit_foo(). You can then write Python "import foo", and Python will search for foo.pyd (as well as foo.py, foo.pyc) and if it finds it, will attempt to call PyInit_foo() to initialize it. You do not link your .exe with foo.lib, as that would cause Windows to require the DLL to be present.
• Note that the search path for foo.pyd is PYTHONPATH, not the same as the path that Windows uses to search for foo.dll. Also, foo.pyd need not be present to run your program, whereas if you linked your program with a dll, the dll is required. Of course, foo.pyd is required if you want to say import foo. In a DLL, linkage is declared in the source code with __declspec(dllexport). In a .pyd, linkage is defined in a list of available functions.

都需要轉(zhuǎn)義的，目前你的類已經(jīng)實(shí)現(xiàn)了xss過濾
你只需要再加上filter

public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
    HttpServletRequest req=(HttpServletRequest)request;
    chain.doFilter(new XssHttpServletRequestWrapper(req), response, chain);
}

int (*p)[5] = &arr;

你就可以理解成 *p 是 arr 的別名，也就是 p 的值等于 &arr。
所以你想要通過 p 獲取數(shù)組的值，需要 *(*p)，這是第一個(gè)元素，第二個(gè)元素 *(*p + 1) 以此類推。

第一次和第二次采集的是同樣的內(nèi)容嗎？把$query->all()打印出來看看， 第二次應(yīng)該是沒有選擇到內(nèi)容

直接寫配置的路徑的話，webpack識別不了。所以要加上~這個(gè)符號，用來告訴webpack這個(gè)路徑是絕對路徑

你認(rèn)為那些是常用漢字？

1. 把你認(rèn)為是常用的漢字存儲到字典中。
2. 去網(wǎng)上找這么個(gè)字典。

換個(gè)思路通過忽略文件間接實(shí)現(xiàn)：單獨(dú)弄個(gè)文件，把想忽略的內(nèi)容放到里面，使用時(shí)代碼中引入文件內(nèi)容，gitignore 這個(gè)文件。

原型污染，一般不改變默認(rèn)方法執(zhí)行的話，危險(xiǎn)不是太大
如果改變了默認(rèn)方法，如果還有其他庫，則可能出現(xiàn)未知問題。

vue-cli 官方腳本搭建不是可以選擇是否要eslint嗎，選到的話直接幫你配置好了

思路是：在 QMainWindow 里面創(chuàng)建一個(gè) layout，然后把 GridLayout2 窗口加入 layout 里面（這個(gè)思路有點(diǎn)問題，我記錯(cuò)了）

在 PyQt4 里面，QMainWindow 自己本來已經(jīng)有一個(gè) layout 了，你只需要調(diào)用 setCentralWidget 給 QMainWindow 指定一個(gè) widget 就好了。

題外話：建議用 PyQt5 + python3 來做練習(xí)。PyQt4 已經(jīng)過去好久了，5 的資源應(yīng)該更多一點(diǎn)。

代碼如下：

import sys
from PyQt4 import QtGui
from PyQt4.QtGui import *


class GripLayout2(QtGui.QWidget):
    def __init__(self, parent=None):
        super(GripLayout2, self).__init__(parent)
        self.initUI()


    def initUI(self):
        title = QtGui.QLabel('Title')
        author = QtGui.QLabel('Author')
        review = QtGui.QLabel('Review')
        titleEdit = QtGui.QLineEdit()
        authorEdit = QtGui.QLineEdit()
        reviewEdit = QtGui.QTextEdit()
        grid = QtGui.QGridLayout()
        grid.setSpacing(10)
        grid.addWidget(title, 1, 0)
        grid.addWidget(titleEdit, 1, 1)
        grid.addWidget(author, 2, 0)
        grid.addWidget(authorEdit, 2, 1)
        grid.addWidget(review, 3, 0)
        grid.addWidget(reviewEdit, 3, 1, 5, 1)
        self.setLayout(grid)
        self.setWindowTitle('grid layout')
        self.resize(350, 300)


class Mainwindows(QMainWindow):
    def __init__(self):
        super(Mainwindows, self).__init__()
        self.resize(1024,768)

        self.subwidget = GripLayout2(self)
        self.setCentralWidget(self.subwidget)


app = QtGui.QApplication(sys.argv)
ui = Mainwindows()
ui.show()
sys.exit(app.exec_())
        

1. 不是，TeamViewer操控電腦用戶是知道的，這個(gè)暫且叫做前門
2. 后門一般是在目標(biāo)主機(jī)運(yùn)行一個(gè)常駐進(jìn)程的程序，一般是基于TCP的，當(dāng)TCP連接進(jìn)來后，分析傳來的數(shù)據(jù)包并執(zhí)行相應(yīng)的命令。

后門一般是打開郵件附件、亂打開了別人發(fā)你的可執(zhí)行文件,系統(tǒng)漏洞這幾種方式弄進(jìn)來的

你用的是：

        <dependency>
            <groupId>com.alibaba.spring.boot</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>1.0.2</version>
        </dependency>

這個(gè)版本吧？

很不幸，這個(gè)項(xiàng)目已經(jīng)被廢棄了，而新的 https://github.com/dubbo/dubb... 項(xiàng)目則不支持注解方式。

hexo generate有一個(gè)watch參數(shù)，source/_post中的md文件有改動，就會自動publish
hexo generate --watch >> /tmp/hexo_deploy.log 2>&1 &

沒問題啊，意思是“正確的Java版本”

js不支持positive lookbehind，覺得這樣的結(jié)果是因?yàn)檎齽t表達(dá)式對象無視了不認(rèn)識的(?<=)以及之后的所有表達(dá)式，所以只匹配了一個(gè)a

Laravel提供了中間件優(yōu)先級, 這是默認(rèn)的中間件優(yōu)先級, 其它的都要排在它們后面

//illuminate/Foundation/Http/kernel.php
protected $middlewarePriority = [
    \Illuminate\Session\Middleware\StartSession::class,
    \Illuminate\View\Middleware\ShareErrorsFromSession::class,
    \Illuminate\Auth\Middleware\Authenticate::class,
    \Illuminate\Session\Middleware\AuthenticateSession::class,
    \Illuminate\Routing\Middleware\SubstituteBindings::class,
    \Illuminate\Auth\Middleware\Authorize::class,
];

你可以在App/Http/Kernel.php中自定義你的優(yōu)先級:

protected $middlewarePriority = [
    \Illuminate\Session\Middleware\StartSession::class,
    \Illuminate\View\Middleware\ShareErrorsFromSession::class,
    \App\Http\Middleware\Cross::class,
    \App\Http\Middleware\Options::class,
    \Illuminate\Auth\Middleware\Authenticate::class,
    \Illuminate\Session\Middleware\AuthenticateSession::class,
    \Illuminate\Routing\Middleware\SubstituteBindings::class,
    \Illuminate\Auth\Middleware\Authorize::class,
];
