Ask the question about forced download of header

Ask a newbie about the mandatory download of the header. I have been studying for a long time and don't know how to solve it. please ask your predecessors to answer this question.

Error message: readfile (http://tsmusic24.tc.QQ.com/105588684.mp3): failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request

The browser can access the link normally, but cannot forcibly download the link using the header. try curl access and get the 400 status code.

I tried it. yes, no matter local or official domain name. Is it a configuration problem?

Can I post some of your function code? I tried not to run properly both locally and on the server.

You have downloaded the MP3 file directly by running your code locally.

No part of the code can be downloaded by directly copying the code. you do not need to check the code and start with other problems. for example, if some function libraries on the server are not available, or php Download Configuration, etc.

That is to say, what is the complete mp3 file downloaded?

Don't talk nonsense on the upstairs! Is this download?

Which of the following 203 bytes is MP3?

Open the link in the browser, and the resulting music file is complete (on M), and the header is forcibly downloaded to get an error message (203b)

You can use the text editor to open the downloaded titleworkflow and you will see some error messages.
Correct errors can be obtained.
