如何为弹性 beanstalk Windows 应用程序设置文件夹权限? [英] How can I set folder permissions for elastic beanstalk windows application?

问题描述

我目前正在构建一个 C# WebApi 2 应用程序，我将上传到 Amazon Elastic Beanstalk 实例进行部署.到目前为止我已经成功了，在我的本地机器上，我刚刚完成了文件上传功能的测试，以便客户端上传图片.

I am currently building a C# WebApi 2 application that I will be uploading to an Amazon Elastic Beanstalk instance to deploy. I am having success so far, and on my local machine, I just finished testing the file upload capability in order for clients to upload images.

它的方式是我接受 Web Api 中的 multipart/formdata 并将临时文件(使用随机名称，如 BodyPart_24e246c7-a92a-4a3d-84ef-c1651416e667)保存到 App_Data 文件夹.临时文件被放入一个 S3 存储桶中，我在我的 SQL Server 数据库中创建了一个对它的引用.

The way it goes is I accept the multipart/formdata in the Web Api and save the temp file (with a random name like BodyPart_24e246c7-a92a-4a3d-84ef-c1651416e667) to the App_Data folder. The temporary file is put into an S3 Bucket and I create a reference in my SQL Server database to it.

在本地上传单个或多个文件时测试工作正常，但是当我将应用程序部署到 Elastic Beanstalk 并尝试上传时，我收到类似 找不到路径的一部分 'C:inetpubwwwrootsbeAPI_deployApp_DataBodyPart_8f552d48-ed9b-4ec2-9986-88cbffd673ee'" 或类似的人说访问被完全拒绝.

Testing works fine with single or multiple file uploads locally but when I deploy the application to Elastic Beanstalk and try to upload I get errors like "Could not find a part of the path 'C:inetpubwwwrootsbeAPI_deployApp_DataBodyPart_8f552d48-ed9b-4ec2-9986-88cbffd673ee'" or a similar one saying access is denied altogether.

几个小时以来，我一直试图在网上找到解决方案，但 AWS 文档到处都是，教程/其他问题似乎已经过时.我认为这与没有权限在 EC2 服务器上写入临时文件有关，但我不知道如何解决.

I have been trying to find the solution online for a few hours now, but the AWS documentation is all over the place and tutorials/other questions seem to be outdated. I believe it has something to do with not having permission to write the temporary files on the EC2 server, but I can't figure out how to fix it.

非常感谢.

推荐答案

这在 2013 年 4 月已经成为可能，另见 此处:基本上您需要执行的步骤如下:

This is already possible since April 2013, see also here: Basically the steps you need to perform are the following:

1. 通过解决方案资源管理器在项目的顶层创建一个名为 .ebextensions 的文件夹
2. 在此文件夹中添加您的配置文件，例如 myapp.config(将 myapp 替换为您的 Elastic Beanstalk 的应用程序名称)
3. 将下面显示的代码添加到您刚刚创建的配置文件中.将 MyApp 替换为您在 Visual Studio 中显示的项目名称(不是解决方案名称)

4. 一切就绪！！确保 App_Data 中有一个文件，否则 Visual Studio 不会发布它.

1. Create a folder called .ebextensions in the top-level of your project through the solution explorer
2. Add in this folder your configuration file e.g myapp.config (replace myapp with your Elastic Beanstalk's app name)
3. Add the code displayed underneath to this configuration file you just created. Replace MyApp with your project name (not solution name) displayed in Visual Studio

4. All set!! Be sure there's a file within App_Data otherwise Visual Studio won't publish it.

{
    "containercommands": {
        "01-changeperm": {
            "command": "icacls "C:/inetpub/wwwroot/MyApp_deploy/App_Data" /grant DefaultAppPool:(OI)(CI)"
        }
    }
}
