1，try…except…
try:
while True:
time.sleep(100)
except KeyboardInterrupt:
print('Got signal: SIGINT, shutting down.')
exit(0)
2, 信号处理
def handler(signal_received, frame):
# Handle any cleanup here
if signal_received == signal.SIGINT:
print('SIGINT or CTRL-C detected. Exiting gracefully')
exit(0)
if __name__ == '__main__':
signal.signal(signal.SIGINT, handler=handler) # ctlr + c
建议用try…except的方法，通用性强，代码易读性高。

当使用阻塞式UDP socket时无法执行多任务处理，也无法与用户交互，甚至不能响应ctrl+c中断。为了解决这些问题所以要用非阻塞式udp通信。
1，多线程法
import socket
import signal
import threading
import time
def handler(signal_received, frame):
# Handle any cleanup here
if signal_received == signal.SIGINT:
print('SIGINT or CTRL-C detected. Exiting gracefully')
exit(0)
def task(host, port):
print("udp server is listen on " + str(host) + ':' + str(port))
sock = socket.socket(socket.AF_INET, # Internet
socket.SOCK_DGRAM) # UDP
sock.bind((UDP_IP, UDP_PORT))
while True:
data, addr = sock.recvfrom(1024) # buffer size is 1024 bytes
print("from %s received message: %s" % (addr, data))
if __name__ == '__main__':
signal.signal(signal.SIGINT, handler=handler) # ctlr + c
UDP_IP = "0.0.0.0"
UDP_PORT = 5005
t = threading.Thread(target=task, args=(UDP_IP, UDP_PORT))
t.daemon = True
t.start()
while True:
time.sleep(100)
2, 协程法
官方文档说不要在应用中使用asyncio，而是应该在框架中用
import asyncio
class EchoServerProtocol:
def __init__(self, message, on_con_lost):
self.message = message
self.on_con_lost = on_con_lost
self.transport = None
def connection_made(self, transport):
self.transport = transport
def datagram_received(self, data, addr):
print('Received %r from %s' % (data.decode(), addr))
self.transport.sendto(data, addr)
def error_received(self, exc):
print('Error received:', exc)
def connection_lost(self, exc):
print("Connection closed")
self.on_con_lost.set_result(True)
async def main():
print("Starting UDP server")
# Get a reference to the event loop as we plan to use
# low-level APIs.
loop = asyncio.get_running_loop()
on_con_lost = loop.create_future()
message = 'Hello World!'
# One protocol instance will be created to serve all
# client requests.
transport, protocol = await loop.create_datagram_endpoint(
lambda: EchoServerProtocol(message, on_con_lost=on_con_lost),
local_addr=('127.0.0.1', 9999),
remote_addr=('127.0.0.1', 5005))
try:
while True:
await asyncio.sleep(10) # Serve for 1 hour.
finally:
transport.close()
try:
asyncio.run(main())
except KeyboardInterrupt:
print('Got signal: SIGINT, shutting down.')
exit(0)

正则表达式是在文本中寻找子字符串的一种模式。
Groovy中正则表达式定义是通过 ~'正则表达式'定义的
def regex =~'chese'
| 表达式 | 匹配意义 | 示例 |
|---|---|---|
| ^ | 常用正则表达式 | |
| $ | 行尾。与字符串的尾部或换行符之前的位置相匹配。不包括换行符本身 | |
| . | 匹配除换行符以外的任意一个字符 | |
| \w | 字母和数字 | [0-9A-Za-z] |
| \W | 非字母和数字。\w以外的单个字符 | |
| \s | 空字符 | [\t\n\r\f] |
| \S | 非空字符 | |
| \d | 数字 | [0-9] |
| \D | 非数字 | |
| [] | 指定字符范围 | 如：[0-9] |
| * | 前面元素至少出现0次 | |
| + | 前面元素至少出现1次 | |
| {m} | 前面的元素出现m 次 | |
| {m,} | 前面的元素至少出现m 次 | |
| {m,n} | 前面的元素出现至少m 次，至多n 次 | |
| | | 选择，匹配其中的任何一个 | (a|b)*指a或b出现任意次 |
| () | 正则表达式的群组化 | (ab)* 指ab出现任意次 |
| [\u4E00-\u9FA5] | 汉字 | |
| [^\u4E00-\u9FA5] | 非汉字 |
运算符
==~)用于检查字符串是否匹配 返回true或false
如：
if( "abc" ==~ /abc/)
{
println 'true'
}
else
{
println 'flase'
}
=~)用于在字符串中查找匹配的子字符串
def string = "id=12345"
def matcher = string =~ /id=/
def id = matcher.replaceAll('')
println id //运行结果为：12345

函数分两种一种是用户自定义函数，需要用Call命令调用，一种是回调函数，是在特定的事件后或前自动调用的，所有的回调函数都以圆点开头，所有可用的回调函数参考这里:https://nsis.sourceforge.io/Docs/Chapter4.html#callbacks
nsis变量用Var关键字定义，如：
Var varA;
然后在脚本中给变量赋值
Section Install
StrCpy $varA "123"
Section End
The program files directory (usually C:\Program Files but detected at runtime). On 64-bit Windows, PROGRAMFILES andPROGRAMFILES32 point to C:\Program Files (x86) while PROGRAMFILES64 points to C:\Program Files. UsePROGRAMFILES64 when installing 64-bit applications.
The common files directory. This is a directory for components that are shared across applications (usually C:\Program Files\Common Files but detected at runtime). On 64-bit Windows, COMMONFILES andCOMMONFILES32 point to C:\Program Files (x86)\Common Files while COMMONFILES64 points to C:\Program Files\Common Files.

A symbol that contains the path where NSIS is installed. Useful if you want to reference resources that are in NSIS directory e.g. Icons, UIs etc.
When compiled with support for keeping makensis and the data in the same place (the default on Windows), it is in the same place as makensis, on other platforms it is set at compile time (See the INSTALL file for info). In both instances you can modify it at runtime by setting the NSISDIR environment variable. See section 3.1.3 for more info.
The Windows directory (usually C:\Windows or C:\WinNT but detected at runtime).
The Windows system directory (usually C:\Windows\System or C:\WinNT\System32 but detected at runtime).

This constant is not available on Windows 95 unless Internet Explorer 4 is installed.
The directory that contains Send To menu shortcut items.
The directory that contains shortcuts to the user’s recently used documents.
The directory that contains shortcuts to the user’s favorite websites, documents, etc. The context of this constant (All Users or Current user) depends on the SetShellVarContext setting. The default is the current user.

This constant is available on Windows XP and above.
HWND of the main window (in decimal).
The path to a temporary folder created upon the first usage of a plug-in or a call to InitPluginsDir. This folder is automatically deleted when the installer exits. This makes this folder the ideal folder to hold INI files for InstallOptions, bitmaps for the splash plug-in, or any other file that a plug-in needs to work.
A handful of constants are available as aliases that are not affected by SetShellVarContext: USERTEMPLATES,USERSTARTMENU, USERSMPROGRAMS,USERDESKTOP, COMMONTEMPLATES,COMMONSTARTMENU, COMMONSMPROGRAMS,COMMONDESKTOP and COMMONPROGRAMDATA.
–INSTDIR
The installation directory (INSTDIR is modifiable using StrCpy, ReadRegStr, ReadINIStr, etc. – This could be used, for example, in the .onInit function to do a more advanced detection of install location).
Note that in uninstaller code,INSTDIR contains the directory where the uninstaller lies. It does not necessarily contain the same value it contained in the installer. For example, if you write the uninstaller to WINDIR and the user doesn’t move it,INSTDIR will be WINDIR in the uninstaller. If you write the uninstaller to another location, you should keep the installer’sINSTDIR in the registry or an alternative storing facility and read it in the uninstaller.
The current output directory (set implicitly via SetOutPath or explicitly via StrCpy, ReadRegStr, ReadINIStr, etc)
The command line of the installer. The format of the command line can be one of the following:
"full\path to\installer.exe" PARAMETER PARAMETER PARAMETER
installer.exe PARAMETER PARAMETER PARAMETER
For parsing out the PARAMETER portion, see GetParameters. If /D= is specified on the command line (to override the install directory) it won't show up in $CMDLINE.
The identifier of the language that is currently used. For example, English is 1033. You can only change this variable in .onInit.
