Question

You can use URL and refer to parse the content on the online PHP GET interface provided by other websites. You can also capture the packets directly on the web page. However, using the following PHP code returns 404. Is there something wrong with this header? <?php$ url='http://interface.yy.com/hls/new/get/54880976/54880976/1200?source=wapyy&callback=jsonp2';$refe
