如何为Elastic beantalk Windows应用程序设置文件夹权限？

问题描述

我目前正在构建一个C＃WebApi 2应用程序，该应用程序将上传到Amazon Elastic Beanstalk实例进行部署。到目前为止，我已经取得了成功，在本地计算机上，我刚刚完成了文件上传功能的测试，以便客户端上传图像。

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.

接受Web Api中的multipart / formdata并将临时文件（具有诸如BodyPart_24e246c7-a92a-4a3d-84ef-c1651416e667的随机名称）保存到App_Data文件夹。将该临时文件放入S3存储桶，然后在SQL Server数据库中创建对该文件的引用。

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.

测试可以在本地单个或多个文件上传中正常运行，但是当我将应用程序部署到Elastic Beanstalk并尝试上传时，出现类似的错误路径 C：\inetpub\wwwroot\sbeAPI_deploy\App_Data\BodyPart_8f552d48-ed9b-4ec2-9986-88cbffd673ee的一部分，或者说完全拒绝访问。

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:\inetpub\wwwroot\sbeAPI_deploy\App_Data\BodyPart_8f552d48-ed9b-4ec2-9986-88cbffd673ee'" or a similar one saying access is denied altogether.

我已经尝试了几个小时的在线解决方案，但是AWS文档无处不在，教程/其他问题似乎已经过时了。我相信这与没有权限在EC2服务器上写入临时文件有关，但是我不知道如何解决它。

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online for a few hours now, but the AWS documentation is all over the place and tutorials/other questions seem to be outdated.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

自2013年4月以来这已经成为可能，另请参见：基本上，您执行的步骤需要执行以下操作：

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 （用您的Elastic Beanstalk的应用名称替换myapp）


3. 添加代码显示在您刚创建的此配置文件下方。将 MyApp 替换为在Visual Studio中显示的项目名称（而非解决方案名称）



4. 所有设置！确保 App_Data 中有一个文件，否则Visual Studio不会发布该文件。

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)"
        }
    }
}
