这篇文章 主要学习这两个模块的使用:
nodejs有个request模块,专门处理这些网络请求方面的。 就像.NET也有request,webclient,httpclient啥的。。。
nodejs的request使用方法在这,自己查一下:
而我喜欢用async和await的写法,因此我还引入了request-promise-native 模块, ,这个就相当于.NET中httpclient吧。
好了背景就讲这么多,我们就开始简单的使用request-promise-native,进行模拟提交。
我用淘宝镜像安装模块,会比较快比较快一些,注册淘宝镜像方式:
npm install -g cnpm --registry=
然安装模块:
cnpm install --save request cnpm install --save request-promise-native
我们登陆后 ,尝试发一篇文章,然我们分析一下提交的东西:
主要是 Cookie以及 FormData。
好了,然后我们写一个 cnblogs,来处理提交,代码:
const request = require('request-promise-native'); // const proxy = 'http://127.0.0.1:8888'; const url = 'https://i.cnblogs.com/EditPosts.aspx?opt=1'; class Cnblogs { static async save({ title, content, postdate }) { let response = await request({ url: url, method: 'POST', headers: { Cookie: '[隐私隐私隐私]', }, form: { __VIEWSTATE: '===========', __VIEWSTATEGENERATOR: 'FE27D343', Editor$Edit$txbTitle: title, Editor$Edit$EditorBody: `<p style="color: red; font-weight: bold;">原文发布时间为:${postdate} —— 来源于本人的百度文章 [由搬家工具导入]</p>${content}`, Editor$Edit$APOptions$Advancedpanel1$cklCategories$0: '1031596', Editor$Edit$Advanced$ckbPublished: 'on', Editor$Edit$Advanced$chkDisplayHomePage: 'on', Editor$Edit$Advanced$chkComments: 'on', Editor$Edit$Advanced$chkMainSyndication: 'on', Editor$Edit$lkbPost: '发布' } }); return response; } } module.exports = Cnblogs;
const cnblogs = require('./cnblogs'); const main = async () => { try { let response = await cnblogs.save('测试','测试内容','2018-01-01'); console.log(response); } catch (err) { console.error('[ERROR]', err); } }; main();

抓取文章也是很简单的,为了方便从response查找dom,我们可以用这个模块 cheerio : , 就类似于我们做.NET的时候会用 HtmlAgilityPack 来查找dom一样。
cheerio 可以去看看,他的语法跟jquery一样,使用起来很方便。
The above is the detailed content of Graphic and text code introduction to the knowledge of moving tools implemented by Nodejs. For more information, please follow other related articles on the PHP Chinese website!

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.
