Example sharing of how to export html to pdf using phantomjs
Recently we will build a PDF conversion function for our article service. After comparison, I think phantomjs is better at conversion. This article mainly introduces a summary of the method of exporting html to pdf with phantomjs. Friends who need it can refer to it. I hope it can help everyone.
Environment
centos x86_64
Download
You can download it from the official website: Official website
Or wget can also be used:
wget -P /tmp/ https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-linux-x86_64.tar.bz2
INSTALLATION
// 解压 tar xjf /tmp/phantomjs-2.1.1-linux-x86_64.tar.bz2 -C /usr/local/ // 重命名 mv /usr/local/phantomjs-2.1.1-linux-x86_64 /usr/local/phantomjs // 建立软连接 ln -s /usr/local/phantomjs/bin/phantomjs /usr/local/bin/ 现在可以在终端执行phantomjs --version查看是否安装成功
CONFIGURATION
It’s not enough now. If phantomjs is used for conversion, there will be some problems:
Chinese garbled characters
Inconsistent font thickness
Solution:
1: Chinese garbled characters
yum -y install bitmap-fonts bitmap-fonts-cjk
2: Inconsistent font thickness
This is the reason why fonts do not exist in centos, and fonts can be imported.
Install the font management tool: yum install -y fontconfig mkfontscale
Visit c:\windows\fonts and copy the required fonts. Then upload it to /usr/share/fonts on the server
and execute the three commands mkfontscale, mkfontdir, fc-cache -fv, and then restart the server (Reboot).
Code usage
Start now, you can write the code:
import phantom from 'phantom'; const pageToPdf = (url) => { phantom.create().then((ph) { ph.createPage().then((page) => { page.open(url).then((status) => { // 配置存储的pdf地址 page.render('存储的地址.pdf').then((status) => { console.log('Page rendered'); ph.exit(); }); }); }); }); }; pageToPdf('https://www.tongbanjie.com');
Result
ok, now you can deploy the code to try For a moment.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

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.
