Translation: AccessServer Handler cannot upload files.

[bogerj]

Description

I used the AccessServer's handler to receive requests from the frontend, but I found that the ContentLength of the received POST request is always 0, and there is no data in the body either.

前端通过 表单上传了一个文件，但是后台无法接受文件

To Reproduce

I created a form in the frontend to upload files, but the backend is not receiving the files.

Thanks for using Wails and reporting this issue.

Unfortunately this is a WebView2 issue with multi-part POST data, and beyond our control. Please see the tracking issue on the webview2feeeback repo: MicrosoftEdge/WebView2Feedback#2162

May I ask ， if there are any other ways to achieve the function of uploading files from web pages to specific interfaces

Use Go to do the job. We don't recommend using JS for anything other than view.
