[英]Retrieve Azure environment variables in NodeJs
I have an app service set up in Azure with a static built NodeJS web application.我在 Azure 中设置了一个应用服务,其中包含一个静态构建的 NodeJS Web 应用程序。 The application runs fine and I want to move the api key and hostname of the api to variables in the environment.应用程序运行良好,我想将 api 的 api 密钥和主机名移动到环境中的变量中。
In Azure->Settings->Configuration->Application Settings I have added two environment variables and set a value for each.在 Azure->Settings->Configuration->Application Settings 中,我添加了两个环境变量并为每个变量设置了一个值。
In my Constants.js file I have在我的 Constants.js 文件中,我有
export const token = process.env.API_KEY;
export const host = process.env.API_HOST;
But process.env.API_KEY is always null.但 process.env.API_KEY 始终为空。
I have even tried :我什至尝试过:
export const token = process.env["API_KEY"];
To no avail.无济于事。 What am I doing wrong?我究竟做错了什么?
Both of the code you provided all work on my side.你提供的两个代码都在我这边工作。
export const token = process.env.API_KEY;
export const token = process.env["API_KEY"];

Update:更新:
const http = require('http');
//var APPINSIGHTS_INSTRUMENTATIONKEY= process.env.APPINSIGHTS_INSTRUMENTATIONKEY;
const server = http.createServer((request, response) => {
var a,b,c;
if(process.env.NODE_ENV === "production")
{
a= process.env.NODE_ENV ;
b= process.env.APPINSIGHTS_INSTRUMENTATIONKEY;
c= process.env.KEY_VALUE;
}
else if(process.env.NODE_ENV === "development")
{
a="Welcome";
b="testparams";
c="testvalue";
}
response.writeHead(200, {"Content-Type": "text/plain"});
response.end(a+" && "+b+"myCustomKey="+c);
});
const port = process.env.PORT || 1337;
server.listen(port);
console.log("Server running at http://localhost:%d", port);
I ran into this same issue and had the same env vars (mentioned in a follow up answer by the author) showing then finally found that the scripts used by create-react-app specifically expose those vars plus any beginning with REACT_APP_
.我遇到了同样的问题,并且有相同的 env vars(在作者的后续回答中提到)显示然后最终发现 create-react-app 使用的脚本专门公开这些 vars 以及任何以REACT_APP_
开头的REACT_APP_
。
I tweaked the logic to allow for additional env vars to pass through, or you could rename you're variables to use the above prefix.我调整了逻辑以允许通过其他环境变量,或者您可以重命名变量以使用上述前缀。
