AngularJS发送POST的OPTIONS请求，而不是 [英] AngularJS Sends OPTIONS request instead of POST

问题描述

我想上传图片到我的S3存储。我使用AngularJS v1.2.13。 当我使用的显示在他们的文档简单的情况下，一切工作正常（与动作标签提交表单）。不过，如果我想这样做与 NG-点击角的方式角发送选项的要求，而不是 POST 的要求。

I'm trying to upload a picture to my S3 bucket. I'm using AngularJS v1.2.13. When I use the simple case as displayed in their docs (submit form with action tag) everything works fine. However, if I want to do it the Angular way with ng-click Angular sends an OPTIONS request instead of a POST request.

以下是服务code，它首先进入的服务器，以获得一个签名（我知道，部分是罚款），然后尝试开机自检的一切。

The following is the Service code, it first goes to the server to get a signature (I know that part is fine) then tries to POST with everything.

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;
});

我是什么做错了吗？
