使用我自己的型号forge autodesk显示自己的CSV数据

Question

希望大家一切都好。我在在Autodesk Forge参考应用程序中显示自己的FORGE数据遇到困难。我当前的.env文件如下。但是，每当我在http：// localhost中启动它时：9000/上传我所获得的一切都是空白的空屏幕。

if (process.env.ENV == "local") {
    require("dotenv").config({
        path: __dirname + "/../.env",
    });
}

Answer 1

因为有这条线 forge-dataviz-iot-iot-reference-app/server/router/index.js＃l25 ，您必须指定env = local在执行NPM运行dev之前。否则，它不会读取.env的内容。

if (process.env.ENV == "local") {
    require("dotenv").config({
        path: __dirname + "/../.env",
    });
}

或者，您可以将其更改为以下

require("dotenv").config({
        path: __dirname + "/../.env",
});

Answer 2

在您的目录中安装dotenv

npm install dotenv

创建config.js文件，然后添加以下代码；

const dotenv = require('dotenv');
dotenv.config();
module.exports = {
    // Set environment variables or hard-code here
    azure: {
        azure_conn_string: process.env.AZURE_IOT_HUB_EVENT_HUB_CONNECTION_STRING
    }
};

更新您的localser.js文件

const { app, router } = require("./app.js");
const config = require('./config');
app.use(router);
const server = require("http").createServer(app);

if (config.azure.azure_conn_string) {
    require("./RealTimeApi.js").createSocketIOServer(server);
}

const PORT = process.env.PORT || 9000;

async function start() {
    try { server.listen(PORT, () => { console.log(`localhost: ${PORT}`); }); } catch (error) { console.log(error); }
} start();
