Add CORS header to an http request using Ajax












0















I have developed a Restfull application and I'd like to add another web application to consume its services so I make this Ajax call :



 $.ajax({
type: "Post",
async: false,
url: "ip_adress/Inviter/api/Account/Register",
data: donne,
headers: { "Access-Control-Allow-Origin:": "*"},
success: function (data) {
console.log(data);
var tab = ;
tab["username"] = username;
tab["password"] = pwd;
var isLogged = Login.CheckCredential(tab, username);
return isLogged;
},
error: function (xhr, status, error) {
console.log(xhr);
console.log(status);
console.log(error);
}

});


I get this exception :




Object {readyState: 0, status: 0, statusText: "SyntaxError: Failed to
execute 'setRequestHeader' …-Origin:' is not a valid HTTP header
field name."} error DOMException: Failed to execute 'setRequestHeader'
on 'XMLHttpRequest': 'Access-Control-Allow-Origin:
' is not a valid
HTTP header field name.




So I need to know :




  • How can I enable the CORS in this situation?


  • How can I fix my code?

    The server needs to set the header, as the server decides who's allowed to access and from where. So the answer to your first question is: Add the header to your server. This should make your second question obsolete.

    Access-Control-Allow-Origin is a http response header, returned by the server. See developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS for details.

You can't authorize yourself like that. It's a response header; details in the specification. The server you're sending the request to has to send that header back to let the browser know it's okay to allow your page to send an ajax request to that server. There's nothing you can do in your client-side code if the server you're trying to request from doesn't allow your origin.
