我使用1.8.2 SDK在Google App Engine上创建了一个全新的项目。

我正在尝试构建一个文件上传器,本地文件上传器工作正常,部署它并尝试上传后,我收到以下错误:

POST http://test2.website.appspot.com/_ah/upload/AMmfu6bj08dli8J-kL3D_xdt…cQ6YCoQx3NC1s4If-C2J1moqV7Lg/ALBNUaYAAAAAUhExcSNKV9D3-0TadzZaCtssmKinnP5T/ 
503 (Service Unavailable) _ah/upload/AMmfu6bj08dli8J-kL3D_xdthBPw4H3jir2X86RQ3dQPlV5LukvcH9t7OP8dK147…6YCoQx3NC1s4If-C2J1moqV7Lg/ALBNUaYAAAAAUhExcSNKV9D3-0TadzZaCtssmKinnP5T/:1

我已在GAE和Google云存储上启用了结算功能。

我用来生成上传网址的代码如下:

public static String getUploadUrl(HttpServletRequest req) {
        String bucket = "website-uploads";
        BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService();
        UploadOptions uploadOptions = UploadOptions.Builder.withGoogleStorageBucketName(bucket);
        return blobstoreService.createUploadUrl("/upload", uploadOptions);
    }

我正在使用普通的servlet来处理多部分帖子:

public void doPost(HttpServletRequest req, HttpServletResponse res)
            throws IOException, ServletException {

        if (!SH.isLoggedIn(req)){
            SH.redirectPage(req, res, 200, "/login");
            return;
        }

        BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService();
        Map<String, List<BlobKey>> blobs = blobstoreService.getUploads(req);
        List<BlobKey> keys = blobs.get("file");     

        if (keys != null && keys.size() > 0) {
            BlobKey blobKey = keys.get(0);
            SH.setAttribute(req, "blobKey", blobKey.getKeyString());
        } else {
            SH.setAttribute(req, "uploadError", "An error occurred while uploading ...");
        }

        SH.setAttribute(req, "uploadUrl", getUploadUrl(req));
        SH.gotoPage(req, res, 200, JSP.pageUpload);
    }

然后我的表单提交了提交:

<form id='uploadForm' action="${uploadUrl}" method="POST" enctype="multipart/form-data" >
    <input id="imageUploader" name="file" type="file" />
    <input type="submit" name="submitBtn" value="Upload" />
</form> 

查看开/关面板,似乎启用了云存储: enter image description here

我的代码有什么问题,还是Google需要解决的问题?

更新

根据Lipis的评论,我添加了所需的权限:

答案 0 :(得分:3)

我认为您没有从Google云端存储中获取您的应用程序的许可。

从文档中使用步骤number 5,如果您实际上没有使用它,请跳过弃用部分,我只是在其他地方找不到说明。
