I'm building a react.js app and I think I have CORS issues but I can't create a server. I'm therefore using a proxy (such as this one https://cors-anywhere.herokuapp.com/${myApiEndpointHere}).
When I'm using Chrome, I'm able to successfully fetch the data. However when I'm using Firefox or Safari, I get these issues listed below. This CORS issue (on Firefox and Safari) seems also to only happen when the scroll is triggered because both for Firefox, Safari and Chrome, I'm able to get my content and log in to the console.
Firefox:

You should read this: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Allow-Headers
And add this header to the response from the proxy server: Access-Control-Allow-Headers: *
When making Axios GET call to retrieve an image from s3 bucket it creates a preflight check using OPTIONS method. Options method response includes the Access-Controll-Allow-Origin: * header with a wild card but the subsequent GET call fails to retrieve the image.
Browser console out put:
Access to XMLHttpRequest at 'https://example.com' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
Response headers from the OPTIONS call:

Go to bucket permission and configure cors [https://docs.aws.amazon.com/AmazonS3/latest/userguide/ManageCorsUsing.html][s3 cors documentation]
I'm trying to write a JSON file with my ionic 4 app
I tried the following path:
applicationStorageDirectory
cacheDirectory
dataDirectory
and it giving me the same error:
Access to XMLHttpRequest at 'file:///URL/my_file.json' from origin 'http://localhost' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, https
Here is my code for writing a file:
this.file.writeFile(this.file.dataDirectory + "json_data", 'test.json', JSON.stringify(cars_data), {replace: true});
I want to save the JSON data in the JSON file.
Im making an app, where I want to sent $http.get requests to duckduckgo's API but their requests are done over HTTP. Seeing my site is HTTP is get the following error:
angular.js:11756 Mixed Content:
The page at 'URL' was loaded over HTTPS,
but requested an insecure XMLHttpRequest endpoint 'http://api.duckduckgo.com/'.
This request has been blocked; the content must be served over HTTPS.
When I adding the s to my request, I obviously get the following (seeing the CORS isn't setup):
XMLHttpRequest cannot load:
https://api.duckduckgo.com/?q=Undulated%20Tinamou&format=json&pretty=1.
Response to preflight request doesn't pass access control check:
No 'Access-Control-Allow-Origin' header is present on the requested resource.
Origin 'https://URL' is therefore not allowed access. The response had HTTP status code 405.
My question: Is there any was for me to get the json and bypass one of the two stated above?
Edit1:
$http.get('https://api.duckduckgo.com/?q=' + birdname + '&format=json&callback=jsonp&pretty=1').then(function(res){
console.log(res.data);
});
I also tried the following:
$http.jsonp('https://api.duckduckgo.com/?q=' + birdname + '&format=json&callback=jsonp&pretty=1').then(function(res){
console.log(res.data);
});
With the second, I am getting the following error:
Uncaught ReferenceError: json is not defined
I couldn't call my service which gives an error
index.html:1 XMLHttpRequest cannot load http://localhost:14652/api/Employee. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:1873' is therefore not allowed access.
What should i do?
Your browser won't let you make this request because the Access-Control-Allow-Origin (necessary for a cross-domain request) is missing in the header of whatever send your api, if you just want to make some tests you can disable it on your browser by launching it with the following flags:
google-chrome --disable-web-security --allow-file-access-from-files
But you should really read this : http://www.eriwen.com/javascript/how-to-cors/ and have cors working on your server
