Highcharts导出图表exportSettings与svg文件

Question

我想用.Net Core项目在后面渲染地图文件

因此,目的是在Javascript中间件上执行Highmaps库,并将svg文件导出到"node-export-server".

我有一个API从客户端接收一些数据.我想用Highmap库生成SVG映射文件,然后发送到另一个API,它将包含一个中间件来执行PNG/JPG/...导出的节点模块.

将svg文件传递给"node-export-server"模块的方法是什么？我阅读了副文档,但我没有找到方法......(https://github.com/highcharts/node-export-server/blob/master/README.md)

我想通过此示例传递我的SVG文件.

//Include the exporter module
const exporter = require('highcharts-export-server');

//Export settings 
var exportSettings = {
    type: 'png',
    options: {
        title: {
            text: 'My Chart'
        },
        xAxis: {
            categories: ["Jan", "Feb", "Mar", "Apr", "Mar", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"]
        },
        series: [
            {
                type: 'line',
                data: [1, 3, 2, 4]
            },
            {
                type: 'line',
                data: [5, 3, 4, 2]
            }
        ]
    }
};

//Set up a pool of PhantomJS workers
exporter.initPool();

//Perform an export
/*
    Export settings corresponds to the available CLI arguments described
    above.
*/
exporter.export(exportSettings, function (err, res) {
    //The export result is now in res.
    //If the output is not PDF or SVG, it will be base64 encoded (res.data).
    //If the output is a PDF or SVG, it will contain a filename (res.filename).

    //Kill the pool when we're done with it, and exit the application
    exporter.killPool();
    process.exit(1);
});

好吧，这可能不完全是完整的答案，但它可能会引导您走向正确的方向：看看https://github.com/aspnet/JavaScriptServices，它提供了一种将代码传递给 Nodejs 的方法（尽管它是关于服务端渲染，原理类似）。然后，您可以将参数传递给 Nodejs，就像通过 CLI 传递参数一样。
