jQuery AJAX自定义标题

我正在尝试向iContact API发出请求,要求我使用自定义标头进行身份验证(http://developer.icontact.com/documentation/authenticate-requests)。这是我的代码:

$.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);}
});

由于某种原因,请求未通过。但是,当我手动执行相同的请求(使用Chrome REST控制台)时,它可以正常工作。如果我取出自定义标头(API- *),请求会通过,但当然身份验证失败,我会回到常规的HTML页面。

我切换到Firefox并检查了请求/响应标头:

请求:

任何想法在这里出了什么问题?

beforeSend挂钩仅适用于$.ajaxSetup(),因此如果您只想将其添加到$.ajax(),您可以使用headers属性。


如果要将自定义标头(或标头集)添加到单个请求,则只需添加标头属性:

// Request with custom header
$.ajax({
    url: 'foo/bar',
    headers: { 'x-my-custom-header': 'some value' }
});

如果您想为每个请求添加默认标头(或标头集),请使用$.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' } });

如果您想为每个请求添加标题(或标题集),请使用beforeSend$.ajaxSetup()挂钩:

$.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' } });

修改(更多信息):有一点需要注意的是,使用ajaxSetup时,您只能定义一组默认标头,而您只能定义一个beforeSend 。如果多次调用ajaxSetup,则只会发送最后一组标题,并且只会执行最后一次发送前回调。

您在响应中获得302(Redirectional)很奇怪。您是否尝试使用Ajax函数记录错误,以解决问题?这是我使用的一个例子。

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);
                    }


                });

请一定要试试这个问题。

  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;
        });
  }
