Errror using API in chrome browser

I don't know how to fix this issue with using an API. It give me a browser error that says:
Access to XMLHttpRequest at
'file:///C:/Users/Gebruiker/Desktop/PokeMax/GET%20https://api.pokemontcg.io/v2/cards?s'
from origin 'null' has been blocked by CORS policy: Cross origin
requests are only supported for protocol schemes: http, data, chrome,
chrome-extension, chrome-untrusted, https. jquery-3.4.1.min.js:2 GET
file:///C:/Users/Gebruiker/Desktop/PokeMax/GET%20https://api.pokemontcg.io/v2/cards?s
net::ERR_FAILED
If someone knows what the issue is I would love to hear it!
code:
$(document).ready(function (e) {
$("#TheSubmitButton").on("click", function(event){
event.preventDefault();
var Pokemon = $("#search")
.val()
.trim()
console.log(Pokemon);
$.ajax({
url: "GET https://api.pokemontcg.io/v2/cards?" + Pokemon,
dataType: 'json',
method: "GET"
});
});
});
// for (var i = 0; i < response.cards.length; i++) {
// var pokemonCard = $("<img>");
// pokemonCard.attr("src", response.cards[i].imageUrlHiRes);
// $("#card-container").append(pokemonCard);
// }

GoogleDrive API (javascript): no file download because of CORS

With this code, before an year about i could get the file via XMLHttpsRequest.
Now this do not more work, because of the error:
Access to XMLHttpRequest at 'https://drive.google.com/uc?id=1zGxNBh-YTAXu74v855l2b_LPmLUaomqZ&export=download' from origin 'https://encrypt.pdfzorro.com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
Is there a way at now, to get the file via javascript. I can not use any server solution, the file should go direct from googleDrive to the browser from the user.. without go on a server (with php e.g.) first.
function downloadFileContent(fileId){
gapi.client.request({
'path': '/drive/v2/files/' + fileId,
'method': 'GET',
callback: function ( theResponseJS, theResponseTXT ) {
var myToken = gapi.auth.getToken();
var myXHR = new XMLHttpRequest();
myXHR.open('GET', theResponseJS.downloadUrl, true );
myXHR.responseType = 'arraybuffer';
myXHR.setRequestHeader('Authorization', 'Bearer ' + myToken.access_token );
myXHR.onreadystatechange = function( theProgressEvent ) {
if (myXHR.readyState == 4) {
// 1=connection ok, 2=Request received, 3=running, 4=terminated
if ( myXHR.status == 200 ) {
// 200=OK
cossole.log(myXHR.response);
}
}
}
myXHR.send();
}
});
}

Mapbox Geocoding API - 'Cross-Origin Request Blocked' error

I'm trying to call Geocoding API but I'm not having any luck. I keep receiving the following error.
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.mapbox.com/gecoding/v5/mapbox.places/fort%20coll…7nugng&autocomplete=true&bbox=-105.214,40.451,-104.85,40.841. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).
When I add the header it says it can't run the script. Not sure what else to do. My link is formated properly because it works in mapbox search-Playground
var searchId = document.getElementById('mySearch');
searchId.addEventListener('keyup', function onEvent(e) {
if (e.keyCode === 13) {
console.log(searchId.value)
var urlBase = 'https://api.mapbox.com/gecoding/v5/mapbox.places/';
var location = searchId.value;
var bbox = [-105.214, 40.451, -104.850, 40.841]
var query = urlBase + location + '.json?access_token=' + mapboxgl.accessToken + '&autocomplete=true&bbox=' + bbox;
$.ajax({
method: 'GET',
url: query,
success: function(data){
console.log(data)
}
})
}
});

Download Image Using Fetch In ReactJs

I'm trying to download an image using fetch in reactJS. But whenever I call the function, I face the CORS error.
var image_trade_license = new Image();
image_trade_license.crossOrigin = "anonymous";
image_trade_license.src = "https://via.placeholder.com/150/92c952";
// get file name - you might need to modify this if your image url doesn't contain a file extension otherwise you can set the file name manually
var fileName_trade_license = 'trade_license';
image_trade_license.onload = function () {
var canvas = document.createElement('canvas');
canvas.width = this.naturalWidth; // or 'width' if you want a special/scaled size
canvas.height = this.naturalHeight; // or 'height' if you want a special/scaled size
canvas.getContext('2d').drawImage(this, 0, 0);
var blob_trade_license;
// ... get as Data URI
if (image_trade_license.src.indexOf(".jpg") > -1) {
blob_trade_license = canvas.toDataURL("image_trade_license/jpeg");
} else if (image_trade_license.src.indexOf(".png") > -1) {
blob_trade_license = canvas.toDataURL("image_trade_license/png");
} else if (image_trade_license.src.indexOf(".gif") > -1) {
blob_trade_license = canvas.toDataURL("image_trade_license/gif");
} else {
blob_trade_license = canvas.toDataURL("image_trade_license/png");
}
$("#image1").append("<a download='" + fileName_trade_license + "' href='" + blob_trade_license + "'><button>Download Trade License</button></a>");
}
and I am facing this error (occured in browser Console) -
Access to image at 'https://via.placeholder.com/150/92c952' from origin
'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-
Allow-Origin' header is present on the requested resource.
via.placeholder.com/150/92c952:1 Failed to load resource: net::ERR_FAILED

First, Have you ever set mode: "no-cors" in fetch config? Like this:
fetch('https://via.placeholder.com/150/92c952', {
method: 'POST',
mode: "no-cors"
})
If you still receive CORS error. You can disable origin policy in Chrome to continue to call API that without CORS error with This Post
Or, This post could give you more knowledge about CORS in Web Browser.

Download Google Drive file from url and send with post to backend

I am trying to download a file from an url (chrome drive file) in javascript; and want to send it to my backend (php - laravel).
var url = file.downloadUrl !== undefined ? file.webContentLink : file.exportLinks['application/pdf'];
console.log(url) // if I go to url, it downloads the file
if (url !== undefined) {
var remote = new XMLHttpRequest();
remote.open('GET', url);
remote.setRequestHeader('Authorization', 'Bearer ' + gapi.client.getToken().access_token);
remote.setRequestHeader('Access-Control-Allow-Origin', '*');
remote.onload = function(e) {
vm.handle_download(remote.responseText, file, 200); // do something with the fetched content;
};
remote.onerror = function(e) {
vm.handle_download('error response', null, remote.statusText);
};
remote.send();
} else vm.handle_download('no downloadable url', {
file: null,
status: 'error'
});
and on handle
handle_download: function (content, file, status) {
if (status !== 200) {
console.log('error occured on status')
return;
}
}
Failed to load https://drive.google.com/uc?id=1D12321ofd4CNG-m9_Mp4aiDcnibNf&export=download: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://test.dev' is therefore not allowed access.

This is an intended behavior due to same origin policy in the web. Since you're doing this for testing purposes, try this Allow-Control-Allow-Origin chrome extension.
You can read more about how to implement this in Using CORS tutorial.
