Question

我尝试使用phamton-html-to-pdf和ejs创建一个pdf用于模板化。设置工作在我的本地开发环境中有效，但不在生产中。问题是在我的服务器prod中创建了pdf，但它是空的。

＆＃13;

const ejs = require('ejs');
const fs = require('fs');
const conversion = require("phantom-html-to-pdf")({
		phantomPath: require("phantomjs-prebuilt").path
});



function createPdf  (data, template, directory) {

	var options = {};
	var html = ejs.renderFile(__dirname + `/template/${template}.ejs`,  {data: data}, options, function(err, str){
		if(err){
			return err
		}
	    return str
	});

	var filepath = null

	conversion({ html: html, printDelay: 5000}, (err, pdf) => {
	  	var output = fs.createWriteStream(`documents/${directory}/${data.Référence}.pdf`)
	  	pdf.stream.pipe(output);
	});
}

module.exports = createPdf;

我不知道在哪里寻找错误，请帮忙

Answer 1

您必须在服务器中安装“libfontconfig”。

macOS sierra update仅适用于phantomjs2。
linux可能还需要另外安装fontconfig包。
Centos - sudo yum install -y fontconfig
Debian / Ubuntu - sudo apt-get install -y libfontconfig

Answer 2

我的phantom-html-to-pdf（0.5.6）有此问题。就我而言，我的配置是：

const pdf = require("phantom-html-to-pdf")({
    // number of allocated phantomjs processes
    numberOfWorkers: 3,
    // timeout in ms for html conversion, when the timeout is reached, the phantom process is recycled
    timeout: 10000,
    // directory where are stored temporary html and pdf files
    tmpDir: __dirname + "/tmp/", 
    phantomPath: "/usr/bin/phantomjs"
});

但是我的phantomPath没用，因为在我的情况下，它们在 phantomPath 上无法执行（出于某些原因，我们有可能将其删除）。

const pdf = require("phantom-html-to-pdf")({
    // number of allocated phantomjs processes
    numberOfWorkers: 3,
    // timeout in ms for html conversion, when the timeout is reached, the phantom process is recycled
    timeout: 10000,
    // directory where are stored temporary html and pdf files
    tmpDir: __dirname + "/tmp/"
});

我的没有phantomPath的配置有效！
