CURL capture failure

Why can I ask a question if CURL capture fails ~
The data on this page cannot be captured using curl ~ How can this problem be solved?
Http://mybus.xiamentd.com/LineDetailQuery? LineId = 118 & direction = 1
Thx!

Adjust your program according to the returned header

$url = 'http://mybus.xiamentd.com/LineDetailQuery?lineId=118&direction=1';print_r(get_headers($url));

Adjust your program according to the returned header

The page seems to have no data even when the page jumps 302 continuously.

So you need to adjust your program
Set CURLOPT_FOLLOWLOCATION if 302 exists.
Set CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE if there is a cookie.

Can a living person be suffocated by the urine?

These two tried last night, but they didn't work.

$ Url = 'http: // mybus.xiamentd.com/LineDetailQuery?
