First, IntroductionThrift is a software framework for the development of extensible, cross-language services. It combines a powerful software stack and code generation engine to build in C + +, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C #, Cocoa, JavaScript, node. js, Smalltalk, and OCaml the seamless and efficient service between these programming languages.Second, installation1.Http://www.apache.org/dyn/closer.cgi?path=/thrift/0.9.2/thrift-0.

Python has complete support for sockets. some of the APIS though have a different signature than the POSIX equivalents. it is therefore possible to write multicast servers and clients in Python. multicasting is the ability to send data to select set of hosts. broadcasting in a network is to send data to all the hosts, unicast is when data is transfered between two hosts (typical one-one communication ). mul
: This article mainly introduces how to count the ip traffic of the client based on nginx access logs in python. if you are interested in the PHP Tutorial, refer to it. Professional statistical websites, such as Baidu Statistics, Google Analytics, and cnzz, provide common statistical indicators for webmasters, such as uv, pv, online duration, and ip address, in addition, due to network reasons, I found that

Salt provides several entry points to the Python application interface, which are often referred to as the * client () API. Each client accesses different parts of the salt, whether from master or minion, each client is detailed as follows:1. Programmatic access to salt2. Salt can be used in CLI scripts or through the
Before writing a script, write a requirement analysisWill write more scripts later, will pay attention to this aspect of Prohibit HTTP requests? Requirements analysisCore Features:By modifying the Hosts file, users are forbidden to visit Baidu and other search enginesImplementation method:Overwrite the Hosts file requirements with the cmd console command copy:

The Ftplib module in PythonThe Ftplib module, which is installed by default in Python, defines the FTP class, where functions are limited and can be used to implement a simple FTP client for uploading or downloading filesFTP Workflow and basic operation can refer to protocol RFC959FTP Login ConnectionFrom ftplib import FTP #加载ftp模块Ftp=ftp () #设置变量Ftp.set_debuglevel (2) #打开调试级别2, show detailsFtp.connect ("IP
Use SocketServer in Python to implement non-blocking communication between the client and the server.
The SocketServer module is used to implement non-blocking communication between the network client and the server.First, let's take a look at the classes available for use in the SocketServer module:BaseServer: contains the core functions of the server and hooks
There is a need to set a field for a key to store timestamps, whenever there is new data, to determine whether the new data timestamp is > before the timestamp, if so, update the timestamp, due to rely on intermediate execution results, so use LUA to reduce the number of client and server-side communication#!/usr/bin/python#-*-coding:utf-8-*-ImportREDISR= Redis. Redis ("127.0.0.1") Lua="""Local key = keys[1
This example describes how Python implements a simple FTP client using Ftplib. Share to everyone for your reference. The implementation method is as follows:

This is the starting exercise on the Python Black Hat, and I have commented on the functions used in it so that it can be easily understood later.The program can access Baidu, return the response information.In addition, I note that there is also a subset of UDP client statements, TCP and UDP comparisons for easy memory.#-*-coding:utf-8-*-#create client, similar
"$push" to use "$addToSet", and if you need to add multiple values, you can use it with "$each" so that you can add non-duplicates, as follows: 1 >>> posts.update ({ _id :p ost[" ]},{" : 2 { " tags : {" $each : [ Python , " Each ]}}}) After the addition, the following is deleted, you can think of arrays as stacks and queues, using "$pop" to operate, such as the above: 1 >>> posts.update ({"_id":p ost["_id"]},{ "$pop": {"tags":
Python-based Tornado framework HTTP client tutorial, pythontornado
Because tornado's built-in AsyncHTTPClient function is too simple, I wrote an HTTP client library based on Tornado. Since I used this library in multiple places, I extracted it from the project, write a separate library tornadohttpclient
TornadoHTTPClient is an efficient asynchronous HTTP
UDP is widely used in network applications that need to transmit data to each other, such as the UDP protocol used by QQ. In the case of poor network quality, packet loss is very serious when using UDP protocol, but UDP consumes less resources, processing speed is fast, UDP is still the commonly used protocol for transmitting data.
Here is the code for implementing a UDP server with Python:
The code is as follows:
