使用Dropzone

Question

我正在尝试使用Dropzone上传文件。上传调用是对Web Api服务的。但是，浏览器返回以下问题“的XMLHttpRequest无法加载http://localhost:444/api/Controller/Upload/xyz123无‘访问控制允许来源’标头出现在所请求的资源。起源‘http://localhost:53006’因此不允许访问。响应的HTTP状态代码为404。“。

下面列出了我的文件上传实施代码。任何建议都表示赞赏。

var myAwesomeDropzone = new Dropzone("#dropzoneForm", {
            acceptedFiles: "application/pdf",
            header: {
                'Authorization': authorizationToken,
                'Cache-Control': null,
                'X-Requested-With': null
            },
            init: function () {
                this.on("processing", function (file) {
                    console.log(app);
                    this.options.url = apiBaseUrl + "/Controller/Upload/" + id;
                });
                this.on("addedfile", function (file) {
                    console.log("added file");
                });
                this.on("success", function (file) {
                    console.log("successfully uploaded file");
                });
            }
        });

HTML code：

<form action="http://BaseUrl/Controller/Upload" method="post" enctype="multipart/form-data" class="dropzone" id="dropzoneForm">
        <div><span>Click here or drag files to upload</span></div>
        <div class="fallback">
            <input name="file" type="file" multiple />
            <input type="submit" value="Upload" />
        </div>
    </form>

服务器端代码：

    [System.Web.Http.HttpPost]
    public async Task<IHttpActionResult> Upload(Guid id)
    {
      // Upload file
    }
