问题描述
好的，我刚刚有机会在Node.js中工作，我正在其中使用axios库从第三方URL中获取数据.
Okay, I just got an opportunity to work in nodejs, where I am using axios library to fetch the data from third party url.
在部署到ENV之前，一切工作都非常顺利.
Everything was working very smoothly until it was deployed to staging ENV.
在使用Rails时遇到类似的问题，发现的解决方案是使用
Similar issue I got while working with rails, and the solution I found was to use
@request['X-Forwarded-For'] = 'XX.YYY.Z.Z'.
现在来看这个问题，已经尝试了
Coming to the issue now, have already tried
options = { headers: { 'X-Forwarded-For': 'XX.YYY.Z.Z' } }，即使在本地env:/
options = { headers: { 'X-Forwarded-For': 'XX.YYY.Z.Z' } } and its not working at all even at local env :/
axios.get(URL, options);这就是我使用它来获取数据的方式，但是它一直在不断加载，
axios.get(URL, options);This is how I am using it to fetch the data, but it keeps loading and loading,
有什么我想念的东西吗?我可以尝试一下吗?
Is there anything I am missing or alternative of it so that I can try that instead?
推荐答案
从express创建应用程序后使用此中间件
use this middleware after creation of app from express
//CORS error solution
app.use((req,res,next)=>{
res.setHeader('Access-Control-Allow-Origin','http://localhost:3000');//your frontend origin
res.setHeader('Access-Control-Allow-Credentials', true);
res.setHeader('Access-Control-Allow-Methods','GET,POST,PUT,DELETE,PATCH');
res.setHeader('Access-Control-Allow-Headers','Content-Type ,Origin, X-Requested-With, Accept, Authorization');
next();
})
希望这会对您有所帮助.如果您有任何疑问，请告诉我.
Hope this will help you. if you have any query then let me know.
