Python 网络编程需要学习哪些网络相关的知识?

Jun 06, 2016 pm 04:22 PM
python

学习Python有很长一段时间了,可是一直感觉都没有啥子明显的进示。最近想了想,还是觉得自己目标不够明确,不清楚到底学了后能做些什么(业余人士,学编程就是爱好),因此什么都在看,但却什么都没成。总结了下,确定在网络编程方面的深入一下,麻烦大家指教下需要学些什么样的东西。

回复内容:

Python网络编程是一个很大的范畴,个人感觉需要掌握的点有:
1. 如何使用Python来创建socket, 如何将socket与指定的IP地址和端口进行绑定,使用socket来发送数据,接受数据,
2. 如何使用Python中处理线程,从而编写可以同时处理多个请求的web服务器
3. 如何使用Python来控制HTTP层的逻辑,包括如何创建http GET,POST,PUT,DELETE请求,如何处理接受到的HTTP请求,这些分别涉及python的httplib, basehttpserver等模块
4. 掌握一种基本的python的web开发框架,比如webpy, django,pylon
5. 了解非阻塞式的HTTP Server,比如tornado
6. 了解twisted, python编写的消息驱动的网络引擎

python 网络编程基础
1. python 网络编程 amazon.com/Foundations-
2. python socket编程的文档 docs.python.org/library
3. python httplib的文档 docs.python.org/library

python常用框架文档:
1. django 的官方网站 djangoproject.com/
2. twisted 的官方网站 twistedmatrix.com/trac/
3. tornado 的官方网站 tornadoweb.org/ 就我个人的经验,不妨:
1.写出基本的TCP连接,知道编写TCP的各个步骤,例如创建socket、绑定port、端口复用等,对TCP稍微做了解,知道协议的每个字段,了解三次握手。
2.了解基本的服务器并发模型,例如多进程、多线程、IO复用
3.了解一些网络库例如twisted

其实想研究深入还得去读《UNP》《TCPv1》之类的书籍,但是这类语言都是基于C的。
我是在Linux下编写C++程序的,我的感觉是要钻研的深入,一般都是用C来描述,
用python这种语言,抽象层次高,容易抓住重点,适合上手,但是同时也规避了很多问题 一般来说分为web编程和网络编程,所以最好分清两者的概念。前者更倾向于去学习一些主流的框架以及自己搭建站点,后者则是从更底层上去描述与实现。所以建议先找到感兴趣的,在好好研究。 可以参考下面这个答案,这个答案对英语不好如何看技术英文文档的问题也有参考性,对照源码读docs.python.org/2/libra对英文有帮助。

不清楚你具体指的是底层的网络编程,还是偏应用的web开发。如果是做网站的话,那是web开发,建议先去看python的web开发框架,推荐从Django开始,文档比较详细
Django:djangoproject.com/ Socket Programming in Python这里有个简单的教程 我也在学,第一感觉是先学好英语 学习完网络编程基础知识后. 强烈建议学习twisted.

Is the conversion speed fast when converting XML to PDF on mobile phone? Is the conversion speed fast when converting XML to PDF on mobile phone? Apr 02, 2025 pm 10:09 PM

The speed of mobile XML to PDF depends on the following factors: the complexity of XML structure. Mobile hardware configuration conversion method (library, algorithm) code quality optimization methods (select efficient libraries, optimize algorithms, cache data, and utilize multi-threading). Overall, there is no absolute answer and it needs to be optimized according to the specific situation.

How to convert XML files to PDF on your phone? How to convert XML files to PDF on your phone? Apr 02, 2025 pm 10:12 PM

It is impossible to complete XML to PDF conversion directly on your phone with a single application. It is necessary to use cloud services, which can be achieved through two steps: 1. Convert XML to PDF in the cloud, 2. Access or download the converted PDF file on the mobile phone.

What is the function of C language sum? What is the function of C language sum? Apr 03, 2025 pm 02:21 PM

There is no built-in sum function in C language, so it needs to be written by yourself. Sum can be achieved by traversing the array and accumulating elements: Loop version: Sum is calculated using for loop and array length. Pointer version: Use pointers to point to array elements, and efficient summing is achieved through self-increment pointers. Dynamically allocate array version: Dynamically allocate arrays and manage memory yourself, ensuring that allocated memory is freed to prevent memory leaks.

Is there a mobile app that can convert XML into PDF? Is there a mobile app that can convert XML into PDF? Apr 02, 2025 pm 09:45 PM

There is no APP that can convert all XML files into PDFs because the XML structure is flexible and diverse. The core of XML to PDF is to convert the data structure into a page layout, which requires parsing XML and generating PDF. Common methods include parsing XML using Python libraries such as ElementTree and generating PDFs using ReportLab library. For complex XML, it may be necessary to use XSLT transformation structures. When optimizing performance, consider using multithreaded or multiprocesses and select the appropriate library.

Recommended XML formatting tool Recommended XML formatting tool Apr 02, 2025 pm 09:03 PM

XML formatting tools can type code according to rules to improve readability and understanding. When selecting a tool, pay attention to customization capabilities, handling of special circumstances, performance and ease of use. Commonly used tool types include online tools, IDE plug-ins, and command-line tools.

It is not easy to convert XML to PDF directly on your phone, but it can be achieved with the help of cloud services. It is recommended to use a lightweight mobile app to upload XML files and receive generated PDFs, and convert them with cloud APIs. Cloud APIs use serverless computing services, and choosing the right platform is crucial. Complexity, error handling, security, and optimization strategies need to be considered when handling XML parsing and PDF generation. The entire process requires the front-end app and the back-end API to work together, and it requires some understanding of a variety of technologies.

How to open xml format How to open xml format Apr 02, 2025 pm 09:00 PM

Use most text editors to open XML files; if you need a more intuitive tree display, you can use an XML editor, such as Oxygen XML Editor or XMLSpy; if you process XML data in a program, you need to use a programming language (such as Python) and XML libraries (such as xml.etree.ElementTree) to parse.
