AngularJS发送OPTIONS请求而不是POST

我试图将图片上传到我的S3桶.我使用AngularJS v1.2.13.
当我使用他们的文档中显示的简单情况(提交表单与动作标签)一切正常.但是,如果我想这样做,Angular的方式用ng-click Angular发送OPTIONS请求而不是POST请求.

以下是服务代码,它首先去服务器获取签名(我知道那部分是好的)然后尝试POST一切.

myServices.factory('s3', function($http) {
    var service = {};

    service.upload = function(fileName) {

        return $http(
            {
                method:"POST",
                url: "sign",
                data: { "fileName": fileName }
            }
        ).then(
            function(result) {
                // success
                //resolve the promise as the data
                var data = result.data;
                var url = "https://" + data.bucket + ".s3.amazonaws.com/";

                return $http.post(url, {
                    "key": data.key,
                    "AWSAccessKeyId": data.awsKey,
                    "acl": data.acl,
                    "policy": data.policy,
                    "signature": data.signature,
                    "Content-Type": "image/jpeg",
                    "success_action_redirect": "http://localhost:3000/s3Uploaded"
            }).then(
            function(response) {
                // success
                console.log("s3.upload, success: ");
                console.log(response);
            },
            function(response) { 
                // failed
                console.log("s3.Upload, fail: ");
                console.log(response);
            }
        );

    },
        function(response) { 
            // failed
            console.log("s3.sign, fail: ");
            console.log(response);
        }
    );
};

return service;
});

我究竟做错了什么?

我不知道这些资源是否会帮助你,但这听起来像是同样的问题:

HTTP POST turns into OPTIONS

OPTIONS preflight call preceding a $http.post request
