jQuery AJAX自定义标题

Question

我正在尝试对iContact API执行请求,该请求需要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,请求没有通过.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HTML页面.

我切换到Firefox并检查了请求/响应标头:

请求:

Host    app.icontact.com

Access-Control-Request-Me...    GET

响应:

任何想法在这里出了什么问题？

谢谢!

奇怪的是，您在响应中收到 302（重定向）。您是否尝试过使用 Ajax 功能记录错误来解决问题？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);
                    }


                });
