AJAX函数w/Mailgun,获取"错误请求头字段授权不允许Access-Control-Allow-Headers"

Question

我正在努力制作一个发送电子邮件的Mailgun API的AJAX调用.Mailgun上的文档说,发布请求应该发送到" https://api.mailgun.net/v3/domain.com/messages ".我已经包含了mailgun指定的api密钥(他们指示使用'api'的用户名).由于这涉及CORS,我无法通过错误:请求头字段Access-Control-Allow-Headers不允许授权.

但是,我已经检查了网络选项卡中的请求/响应,并且来自Mailgun的响应中的"Access-Control-Allow-Origin"被设置为"*"...这应该表明它应该允许它？(请参阅下面的请求/响应):我已经编辑了实际的域和我的API密钥.

Remote Address:104.130.177.23:443
Request URL:https://api.mailgun.net/v3/domain.com/messages
Request Method:OPTIONS
Status Code:200 OK
Request Headersview source

我的ajax调用代码如下所示,其中我将我的凭据包含在标题中,并将域包含在帖子应该去的地方.不知道是什么导致这不起作用.是因为我正在本地主机上测试吗？我认为,由于响应头中的"访问控制允许原点:*",这会产生重大影响.任何帮助将不胜感激!谢谢.

function initiateConfirmationEmail(formObj){

  var mailgunURL;
  mailgunURL = "https://api.mailgun.net/v3/domain.com/messages"
  var auth = btoa('api:MYAPIKEYHERE');

    $.ajax({
    type     : 'POST',
    cache    : false,
    headers: {"Authorization": "Basic " + auth},
    url      : mailgunURL,
    data     : {"from": "emailhere", "to": "recipient", etc}, 
    success  : function(data) {
      somefunctionhere();
    },
    error  : function(data) {
      console.log('Silent failure.');
    }
  });
  return false;
}

Drazisil 上面是正确的。Access-Control-Allow-Headers: Authorization当您在请求中包含该标头时，响应需要包含该标头，而Authorization不是简单的标头。
