当我在 Node 中的 docker 中运行我的 phantomjs 应用程序时，它工作正常(将 HTML 转换为 Jpeg)。
但是，当我将它发布到 docker 容器时，字体名称不再受到尊重。
此应用程序使用 html-convert npm 将 HTML 转换为 jpeg、pdf 或其他媒体，它是 phantomjs 的包装器
docker 文件:
FROM node:latest
WORKDIR /app
COPY package.json /app
RUN npm install
COPY . /app
CMD node app.js
EXPOSE 8081
包.json
{
"name": "htmlconverter",
"version": "1.0.0",
"description": "",
"main": "app.js",

应用程序.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”后，观察调用 POST 时“Comic Sans”字体的工作情况
然后运行 Docker，观察使用的默认字体:
docker build -t htmlconverter .
docker run -p 8081:8081 htmlconverter
我在 Windows 10 中运行这个
有什么想法吗？
最佳答案
检查以下链接以获取解决方案。 link
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)
