Today, something suddenly finds a strange phenomenon:
When using the pile program (something. php), the progress bar is normal;
On the server, the progress bar changes at a certain time.
After debugging, it is found that the value of bytesTotal is changed to Infinity at that specific time, which must be caused by a divisor of 0.
After investigation, it is found that bytesTotal of LoaderInfo is obtained through the Content-Length field of the Header, and this field does not exist in the Header of the php file to be dynamically generated, resulting in bytesTotal being 0.
The solution is to pre-process the php client and use
Header ("Content-Length:"). $ content_length;

Manually set the Content-Length field of the Header
