jQuery AJAX自定义标题

前端之家收集整理的这篇文章主要介绍了jQuery AJAX自定义标题前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我正在尝试对iContact API执行一个请求,这需要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,请求不会通过.但是,当我手动执行相同的请求(使用Chrome REST控制台)时,它的工作正常.如果我取出了自定义标头(API- *),请求就会通过,但是当然,认证失败,我收到一个常规的HTML页面.

我切换到Firefox并检查了请求/响应头:

请求:

Host    app.icontact.com
User-Agent  Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12

响应:

任何想法在这里出了什么问题?

谢谢!

解决方法

beforeSend钩子只能用于$.ajaxSetup(),所以如果你只想添加到$.ajax(),你可以使用headers属性.

如果要将自定义标头(或一组标头)添加到单个请求中,那么只需添加headers属性

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

如果要为每个请求添加默认标头(或一组标题),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' } });

如果要为每个请求添加标题(或一组标题),请使用带有$.ajaxSetup()的beforeSend钩子:

$.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' } });

编辑(更多信息):有一点需要注意的是,使用ajaxSetup,您只能定义一组默认标题,您只能定义一个beforeSend.如果您多次调用ajaxSetup,则只会发送最后一组标头,并且只会执行最后一个发送回调.
