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 Accept text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language en-us,en;q=0.5 Accept-Encoding gzip,deflate Accept-Charset ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive 115 Connection keep-alive Origin http://184.72.61.244 Access-Control-Request-Me... GET Access-Control-Request-He... api-appid,api-password,api-username,api-version
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.
