I am trying to create a chrome extension which will look up the meaning of input vocabulary from this URL: http://hanviet.org/ajax.php?query=%E6%97%A5&methode=normal
I made an ajax call by using jquery but got an error because of the cross-domain issue: "No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access" . Ok, I guest that instead of make a request directly to the URL, I need to call it through a proxy pages as below:
$.get("/myproxy.php?query=日&methode=normal", function( data ) {
alert( "Load was performed." );
});
After doing a google search, there is another chrome extension named DHC to makes http request: https://www.sprintapi.com/dhcs.html . and It works perfectly!
I am wondering that does DHC tool also send a request through its proxy or there is another way to make a direct request that I dont know.
Thank you!
$.ajax({
type: "GET",
url: 'URL',
jsonp: 'callback',
dataType: 'jsonp',
data: {},
success: loginSuccess,
crossDomain: true,
error: ajaxFailed,
contentType: 'application/json',
async: false
});
function ajaxFailed(result) {
alert("Failed: " + result.status + ' ' + result.statusText);
}
function loginSuccess(data) {
alert('Result: ' + data.d);
}
If you use the developers tools of chrome on that site, on Network tab you will see that after pressing the send
button it loads the content from https://www.sprintapi.com/api/proxy
, so yes, it should be using a proxy.
Even more, as you say the Access-Control-Allow-Origin would'nt let they did it on another way I think.
