jQuery AJAX Custom Header
I'm trying to perform a request to the iContact API which required me to use a custom header for authentiation (htt开发者_JAVA百科p://developer.icontact.com/documentation/authenticate-requests). This is my code:
$.ajax({
type: "GET",
url: "https://app.icontact.com/icp/a/",
contentType: "application/json",
beforeSend: function(jqXHR, settings){
jqXHR.setRequestHeader("Accept", "application/json");
jqXHR.setRequestHeader("Api-Version", iContact_API_version);
jqXHR.setRequestHeader("Api-AppId", iContact_appID);
jqXHR.setRequestHeader("Api-Username", iContact_username);
jqXHR.setRequestHeader("API-Password", iContact_appPassword);}
});
For some reason the request doesn't go through. However, when I perform the same request manually (using Chrome REST console) it works just fine. If I take out the custom headers (API-*), the request goes through but of course the authentication fails and I get back a regular HTML page.
I switched over to Firefox and checked Request/Response Headers:
Request:

Any ideas what's going wrong here?
Thanks!
The beforeSend hook is only available for $.ajaxSetup()
so if you want to add it only to the $.ajax()
you simply can go with the headers
property.
If you want to add a custom header (or set of headers) to an individual request then just add the headers property:
// Request with custom header
$.ajax({
url: 'foo/bar',
headers: { 'x-my-custom-header': 'some value' }
});
If you want to add a default header (or set of headers) to every request then use $.ajaxSetup()
:
$.ajaxSetup({
headers: { 'x-my-custom-header': 'some value' }
});
// Sends your custom header
$.ajax({ url: 'foo/bar' });
// Overwrites the default header with a new header
$.ajax({ url: 'foo/bar', headers: { 'x-some-other-header': 'some value' } });
If you want to add a header (or set of headers) to every request then use the beforeSend
hook with $.ajaxSetup()
:
$.ajaxSetup({
beforeSend: function(xhr) {
xhr.setRequestHeader('x-my-custom-header', 'some value');
}
});
// Sends your custom header
$.ajax({ url: 'foo/bar' });
// Sends both custom headers
$.ajax({ url: 'foo/bar', headers: { 'x-some-other-header': 'some value' } });
Edit (more info): One thing to be aware of is that with ajaxSetup
you can only define one set of default headers and you can only define one beforeSend
. If you call ajaxSetup
multiple times, only the last set of headers will be sent and only the last before-send callback will execute.

It's strange that you are getting a 302 (Redirectional) in the response. Have you tried logging error with the Ajax function, to troubleshoot the problem? Here is an example of something I used.
console.log(" call back url :"+ callBackURL);
$.ajax({
url: callBackURL,
type: 'post', //'GET' in your case
contentType: 'application/json; charset=utf-8',
dataType: 'json' , // explicitly mentioning datatype
success: function(json) {
console.log(" reponse :"+ json);
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
console.log("error :"+XMLHttpRequest.responseText);
}
});
please try this surely you can get the problem solve.
function FormSubmit()
{
$.ajax({
type: "POST",
url: 'index.php',
data: $("#form_main").serialize(),
async: false }).done(function( data ) {
$("#Response").hide();
if (isNaN(data)) {
dispmsg = "<div class='alert alert-danger' role='alert'>Oops..Something had gone wrong! Please try again!</div>";
$("#assess_me_response").html(dispmsg); setTimeout('ResetForm();',3000);
}
else {
dispmsg = "<div class='alert alert-success' role='alert'>Thank you for sharing the details. Our Consultant will contact you shortly!</div>"; $("#assess_me_response").html(dispmsg); setTimeout('Redirect();',3000);
}
return true;
});
}
