服务器端的HTML到pdf转换？
[英]Html to pdf conversion at server side?
问题描述
we are creating a pdf file from the html file using the package princexml pdf converter. 
我们正在使用包princexml pdf转换器从html文件创建一个pdf文件。 For the Creation of the html file the data has given by the server. 对于创建html文件，数据由服务器提供。 In the browser using jquery the input string(html code) is created for the pdf creation. 在使用jquery的浏览器中，为pdf创建创建输入字符串（html代码）。 After receiving the input string from the browser, the server creates a html file which is the input to the princexml pdf converter for the pdf creation. 从浏览器接收到输入字符串后，服务器会创建一个html文件，该文件是princexml pdf转换器的输入，用于创建pdf。
Example for the input string
var sample = "<html>text</html>";//browser side
sample.html converted to sample.pdf //server side
Is it possible to do the same thing at server side without help of the browser ? 没有浏览器的帮助，是否可以在服务器端执行相同的操作？

You can use a headless browser like http://phantomjs.org/ . 您可以使用像http://phantomjs.org/这样的无头浏览器。 This allows to generate images from rendered pages. 这允许从渲染页面生成图像。 See also http://www.lelesys.com/en/media/technology/phantomjs-as-screen-capture-to-generate-image-pdf-files.html 另见http://www.lelesys.com/en/media/technology/phantomjs-as-screen-capture-to-generate-image-pdf-files.html
This allows you to use jquery and everything else - since it uses the acutal rendering engine. 这允许您使用jquery和其他所有东西 - 因为它使用了实际渲染引擎。 I guess you do not even need princexml then. 我猜你甚至不需要princexml。 There is also a faq page regarding capture: http://phantomjs.org/screen-capture.html 还有一个关于捕获的常见问题解答页面： http ： //phantomjs.org/screen-capture.html

I know this is a bit old question but since I found a great module I thought of sharing it with everyone. 我知道这是一个有点老问题但是因为我找到了一个很好的模块，我想与大家分享。
Module named Puppeteer that can make you run the Chrome in Headless mode and also interact with it via API. 名为Puppeteer的模块可以让您在无头模式下运行Chrome，并通过API与其进行交互。 So now you can create a template and take the values of the placeholders of that template via POST call and generate the PDF on the fly, in server . 现在，您可以创建一个模板，并通过POST调用获取该模板的占位符值，并在服务器中动态生成PDF 。
I created a small POC and here is the link to it: Demo-Puppeteer 我创建了一个小POC，这里是它的链接： Demo-Puppeteer
Let me do a bit explanation here: 我在这里做一些解释：
...........
const content = await compile(templateName, data);
/***
* Launched the headless chrome in memory.
*/
const browser = await puppeteer.launch();
/***
* Created a new page(tab)
*/
const page = await browser.newPage();
/***
* Set the content of the new page
*/
await page.setContent(content, { waitUntil: 'networkidle0' });
/***
* Telling chrome to emulate screen i.e how the page looks if
* it would have been rendered in the normal browser.
*/
await page.emulateMedia('screen');
const byteArray = await page.pdf({
format: "A4",
landscape: true,
scale: 1.29,
printBackground: true
});
const buffer = Buffer.from(byteArray, 'binary');
/**
* We don't need the acknowledgement of this call that is the
* reason we are not waiting for this call to return.
*/
browser.close();
return buffer;
.......
Now, this buffer is basically a binary data and you have to write it in a file using the file module of Node. 现在，这个缓冲区基本上是一个二进制数据，你必须使用Node的文件模块将它写在一个文件中。

You can do this without using a browser. 您无需使用浏览器即可完成此操作。 Currently you're using jQuery to generate the HTML content, so you need the browser because jQuery runs in the browser, right? 目前你正在使用jQuery来生成HTML内容，所以你需要浏览器，因为jQuery在浏览器中运行，对吧？
You can move the generation of the HTML code to the server side by writing a server side application which generates the needed HTML content, and sends it to the pdf converter. 您可以通过编写生成所需HTML内容的服务器端应用程序将HTML代码的生成移动到服务器端，并将其发送到pdf转换器。
Princexml can be called from many server side programming languages as you can see here: http://www.princexml.com/doc/9.0/ 可以从许多服务器端编程语言中调用Princexml，如下所示： http ： //www.princexml.com/doc/9.0/
Choice one server side language from the list, generate the HTML in that language and send the HTML to the pdf converter. 从列表中选择一种服务器端语言，以该语言生成HTML并将HTML发送到pdf转换器。 That's all. 就这样。
