邮枪&x2B；AngularJS+；http post请求的身份验证

我正在尝试转换下面的示例代码

尝试添加 用户名：“api”， 密码：“yourapikey”

在你的标题请求中，我终于从本地机器上得到了它——从不同的帖子收集信息，并使用这个插件——我能够使它工作。那么这个插件做什么呢？我可以在我的post请求中这样做吗

没有这一点，我就会犯错误

XMLHttpRequest cannot load https://api.mailgun.net/v3/sandboxXXXXXXXXXX.mailgun.org/messages. Request header field Authorization is not allowed by Access-Control-Allow-Headers in preflight response.

• 我错过的东西
• 多部分
• 上下文类型
• encodedURIComponent-用于参数
• base64编码api密钥

var req={method:'POST'，url:url，用户名：“api”，密码：“api key”，数据：dataFields}

    var url = "https://api.mailgun.net/v3/sandboxXXXXXXXXXXXXXXXXX.mailgun.org/messages";
    var dataFields = {
        to: "verified recepient",
        subject: "subject",
        text: "text",
        from: "postmaster address of sandbox domain"
    }

    var req = {
        method : 'POST',
        url: url,
        headers : {
            'Authorization' : 'Basic api:key-XXXXXXXXXXXXXXXX'

    $http(req).then(function(data){
        console.log(data);
    }, function(data){
        console.log(data);
    })
