下载失败 - 没有文件。 反应 JS，Spring 启动

Question

I have created an application where I use React JS as frontend language to upload the file and Spring boot as backend service to save the file into the local machine directory.

Eg: My path where the file I saved file in ubuntu is like /home/user/resume/resume.pdf

I'm trying to download the file from react js by the above path. When I click it shows failed and when I check the url it appends localhost like this http://localhost:3000//home/user/resume/resume.pdf .

I use this code

<a href={candidate.fileUrl} target="_blank" rel="noopener noreferrer" download>{candidate.fileName}</a>

candidate.fileUrl = /home/user/resume/resume.pdf but it shows onclick like this http://localhost:3000/home/user/resume/resume.pdf

Can anyone help me why it appends localhost before my path which results in downloading failed?

Answer 1

When you put in a tag the href parameter and you precede this with "/", the browser will concatenate this compliment as PROTOCOL://SERVER:PORT/

Well, it's how browsers works, so if you don't wanna this, you can append all the path like: "file:///home/user/resume/resume.pdf"
