Phantom JS + Docker: 当从HTML转换时,不尊重html的font-family[英] Phantom JS + Docker: html font-family is not respected when converting from HTML

问题描述

当我在docker中运行phantomjs应用程序时,它可以正常工作(将html转换为jpeg).
但是,当我将其发布到Docker容器中时,字体名称不再受到尊重.

此应用使用HTML-Convert NPM将HTML转换为JPEG,PDF或其他媒体,这是Phantomjs

的包装器

dockerfile:

FROM node:latest
WORKDIR /app
COPY package.json /app
RUN npm install
COPY . /app
CMD node app.js
EXPOSE 8081

package.json

{
  "name": "htmlconverter",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "dependencies": {
    "body-parser": "^1.18.2",
    "ent": "^2.2.0",
    "express": "^4.16.3",
    "generator-azuresfcontainer": "^1.0.0",
    "html-convert": "^2.1.7",
    "html-entities": "^1.2.1",
    "memorystream": "^0.3.1",
    "phantomjs": "*",
    "phantomjs-prebuilt": "*",
    "picture-tube": "^1.0.0"
  },
  "devDependencies": {},
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": ""
}

app.js

var http = require("http");
var express = require('express');
var htmlConvert = require('html-convert');
var url = require('url');
var querystring = require('querystring');
var Readable = require('stream').Readable;
var bodyParser = require('body-parser');

var app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

app.post('/', function (req, res) {
    var html = unescape(req.body.html);
    var format = req.body.format;
    var orientation = req.body.orientation;
    var convert = htmlConvert({
        format: format,
        orientation: orientation
    });
    var s = new Readable();
    s._read = function noop() { };
    s.push(html);
    s.push(null);
    var result = s.pipe(convert());
    result.pipe(res);
});

var server = app.listen(8081, function () {
    var host = server.address().address;
    var port = server.address().port;

    console.log("Example app listening at http://%s:%s", host, port);
});

Postman(从HTML生成JPEG):

http://127.0.0.1:8081/

{
    "html": "<!DOCTYPE html><html><head><style>body {background-color: powderblue; font-family: 'Comic Sans MS';}h1   {color: blue;}p    {color: red;}</style></head><body><h1>This is a heading</h1><p>This is a paragraph.</p></body></html>",
    "format":"jpeg",
    "orientation":"Landscape"
}

在启动" node app.js"

之后,观察"漫画sans"字体工作

然后运行Docker,并观察使用默认字体:

docker build -t htmlconverter .
docker run -p 8081:8081 htmlconverter 

我在Windows 10

中运行此操作

有什么想法?

推荐答案

该字体不在node:latest图像中.您需要首先安装MS字体家庭.我无法将工作的Dockerfile放在一起,但是这些命令应该工作

  1. wget http://ftp.de.debian.org/debian/pool/contrib/m/msttcorefonts/ttf-mscorefonts-installer_3.6_all.deb
  2. dpkg -i ttf-mscorefonts-installer_3.6_all.deb
  3. apt-get install -f -y

第二个命令引发错误,这会导致docker映像构建失败.好吧,如果您找到了忽略此错误的方法,则应该能够在Dockerfile A中包含命令并使用MS字体构建它.

Please add the scripts to the Dockerfile:
RUN apk add fontconfig ttf-dejavu
RUN apk add --no-cache curl &&
cd /tmp && curl -Ls https://github.com/dustinblackman/phantomized/releases/download/2.1.1/dockerized-phantomjs.tar.gz | tar xz &&
cp -R lib lib64 / &&
cp -R usr/lib/x86_64-linux-gnu /usr/lib &&
cp -R usr/share /usr/share &&
cp -R etc/fonts /etc &&
apk del curl

I did it and it works well. (node:12.20-alpine3.12)

其他推荐答案

这就是我让我的应用程序与Puppeteer一起工作的方式.
注意:我切换到Chrome headless,因为Phantomjs是具有阴暗LIC协议的恐龙,没有体面的支持

FROM node:latest

# See https://crbug.com/795759
RUN apt-get update && apt-get install -yq libgconf-2-4

# Install latest chrome dev package and fonts to support major charsets (Chinese, Japanese, Arabic, Hebrew, Thai and a few others)
# Note: this installs the necessary libs to make the bundled version of Chromium that Puppeteer
# installs, work.
RUN apt-get update && apt-get install -y wget --no-install-recommends \
    && wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - \
    && sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list' \
    && apt-get update \
    && apt-get install -y google-chrome-unstable fonts-ipafont-gothic fonts-wqy-zenhei fonts-thai-tlwg fonts-kacst ttf-freefont \
      --no-install-recommends \
    && rm -rf /var/lib/apt/lists/* \
    && apt-get purge --auto-remove -y curl \
    && rm -rf /src/*.deb

RUN echo "deb http://httpredir.debian.org/debian jessie main contrib" > /etc/apt/sources.list \
   && echo "deb http://security.debian.org/ jessie/updates main contrib" >> /etc/apt/sources.list \
    && echo "ttf-mscorefonts-installer msttcorefonts/accepted-mscorefonts-eula select true" | debconf-set-selections \
    && apt-get update \
    && apt-get install -y ttf-mscorefonts-installer \
    && apt-get clean \
    && apt-get autoremove -y \
    && rm -rf /var/lib/apt/lists/*

WORKDIR /app
COPY package.json /app
RUN npm install
COPY . /app
CMD ["node", "app.js" ]
EXPOSE 8081
