Select is important in socket programming, but it is not very popular for beginners of socket programming.
Select write programs. They are just used to writing blocking programs such as connect, accept, Recv, or recvfrom,
That is, when the process
The wsaasyncselect model allows applications to receive network event notifications in the form of Windows messages. this model is set to adapt to the Windows Message Drive environment. Currently, many network applications with low performance
Classes defined in httpserver include httpserver, httpconnection, and httprequest. Httpserver is a very simple HTTP server. Its main function is to create a listening socket, set the read event hander of the listening socket (create multi-process
NIO:
A simple nioserver. Enter http: // localhost: 1234 in the browser. You can see the HTTP request.

The "complete port" model is the most complex I/O model so far. However, if an application needs to manage a large number of sockets at the same time, this model can often achieve the best system performance!
The httpclient version of the article is 3.
There are two methods to implement SSL access.
The first method is to export the required certificate through a browser and then apply the certificate to the code.
The second method implements SSL
Preface:
After a brief introduction to the network layer protocol and HTTP protocol in the previous topic, I believe that you have a general understanding of the protocols in the network. This topic will define a Web server for the HTTP protocol,
The system. sockes namespace implements the Berkeley socket interface. Through this class, we can implement message transmission and transmission between network computers. in this topic that I will discuss below, we will discuss how to use a set of
Review:
Simple and clear! Review Network Programming and learn python by the way.
I. Socket
A socket is a network application on a specific network protocol (such as TCP/IP, ICMP/IP, UDP/IP) suite.ProgramThe provider provides the

Currently, distributed computing Web services are prevalent, and the underlying layers of these network services are inseparable from socket operations. They all have a common structure:1. Read Request2. Decode request3. Process Service4. encode
The select function can communicate with multiple sockets in a non-blocking manner.ProgramIt only demonstrates the use of the select function. The function is very simple. Even if a connection is closed, the current number of connections is not
There are three types of sockets:1. Streaming socket (socket_stream)Provides reliable connection-oriented data transmission services. Data is considered as a byte stream with no length restrictions. For example, FTP uses this protocol.2. datagram
I have been learning PHP before, but I did not expect to study python .. I am sorry to have read some basic syntaxes and system programming, and the thread descriptions in Linux.
Question 1: The flag is base64 encoded and then encrypted to obtain
Due to the limitations of Poll () and select (), the 2.6 kernel introduces the event poll (epoll) mechanism. Although a little complicated, epoll solves their common basic performance problems and adds some new features.
Each call of Poll ()
The premise is that,
When receiving a receipt or reading data, take two steps.
1. Wait for the data to be ready.
2. Copy data from the kernel to the process.
For a network io (socket) (Here we use read as an example), it involves two system objects,
