How does the 'Access-Control-Allow-Origin' header work?

No 'Access-Control-Allow-Origin' header is present on the requested resource—when trying to get data from a REST API
(26 answers)
Closed 3 years ago.
I am connecting to a website via the following code using NodeJS:
request({
method: 'GET',
url: 'https://www.huffingtonpost.com/',
}, function(error, response, body) {
if(error) {
console.log(error);
}
huffpost(body);
});
When I run the code from my html file using Browserify, I get the following error in my Javascript console:
No 'Access-Control-Allow-Origin' header is present on the requested
resource. Origin 'null' is therefore not allowed access. If an opaque
response serves your needs, set the request's mode to 'no-cors' to
fetch the resource with CORS disabled.
I have seen other questions relating to this topic, and they all say to add a "header", but after looking for a while, I still don't understand.
Any and all help is appreciated, and I would be happy to provide any more info.

I have tried using headers with 'Access-Control-Allow-Origin' but this still return the same error. I have also tried using 'no-cors'. This works but then there is no body returned and I need the HTML for parcing.
I also have the below but it did not fix the issue.

I'm trying to run JavaScript as a snippet starting from one domain and do fetch request to a google search and I keep getting this error:
'Access to fetch at 'https://www.google.com/' from origin 'https://www.somewebsite.org' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
I tried many ways to fix it by passing headers and it did work. Not sure at this point what else I can do.`
It is the server (https://www.google.com/ in this case) of the requested resource that is responsible for and controls the CORS headers necessary. In order for you to be able to access the resource from your origin domain, the CORS policy that google serves will have to allow your website to request it.

I'm trying to use axios to make a post request to my backend. Every time I make the request I was receiving this error:
origin 'http://localhost:1234' has been blocked by CORS policy: No
'Access-Control-Allow-Origin' header is present on the requested
resource.
So I added the appropriate header:
const FRONTEND_URL = 'http://localhost:1234'
export async function connect( address:string | undefined, signature:string | undefined ) {
const url = `${SERVER_URL}/connect`;
return await axios.post(
url,
{ address, signature },
{
headers: {
'Access-Control-Allow-Headers': '*',
'Access-Control-Allow-Origin': `${FRONTEND_URL}`,
'content-type': 'application/json',
},
}
);
}
I still get the same error. Why isn't it detecting my Access-Control-Allow-Origin header? (I've restarted servers multiple times)

Since you are running the routes in development at it means using various ports you are running into error due to CORS policy.
You may look up to these answers as they are provided already with so much explanation enable cors.
Also, you may look at documentation of CORS package CORS

I am attempting to read a csv form the source https://stats.oecd.org/Index.aspx?DataSetCode=WILD_LIFE.
Let x be the url above.
<script type="text/javascript">
var data_threatened = d3.csv(x)
.then(function(data){
console.log(data);
})
</script>
However, when I run this script on my local host, I receive the following message:
Access to fetch at
'https://stats.oecd.org/Index.aspx?DataSetCode=WILD_LIFE' from origin
'http://localhost:8888' has been blocked by CORS policy: No
'Access-Control-Allow-Origin' header is present on the requested
resource. If an opaque response serves your needs, set the request's
mode to 'no-cors' to fetch the resource with CORS disabled.
Uncaught (in promise) TypeError: Failed to fetch
Is there a way around this block?
Fetching the file and serving it from the same origin as the script runs would be the most easy. eg. PHP cares little about CORS (assuming that this file occasionally changes). In case it doesn't change, even manually placing it there would suffice.
To let a server-side script fetch the file and then serve it as same-origin, without caching it:
<?php
$url = "https://stats.oecd.org/Index.aspx?DataSetCode=WILD_LIFE";
header("Content-type: text/csv");
echo file_get_contents($url);
?>
Any server-side scripting language should be capable of doing so; I used PHP just to provide an example. One could make WILD_LIFE a variable, so that it could be used to fetch any data-set.

I am working on Webinar Live Streaming Service.
I used Ant Media Server to transcode WebRTC to RTMP.
Now I am working on making new broadcasting instance.
this.antMediaService.createLiveStream('LiveApp',
this.newStream).subscribe((response) => {
this.streamId = 'test';
this.webRTCAdaptor.publish(this.streamId);
}, (error) => {
console.log('unexpected error', error);
});
But I faced such an issue
ailed to load http://domain:5080/LiveApp/rest/broadcast/create: Response to the preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4300' is therefore not allowed access.
How can I resolve it?
Thanks
