跳转的页面进行参数接收

$process_id=input('process_id');
$bid=input('bid');

var process_id=$("#process_id").val();
//环境物品清单，去其他页面
if(process_id==1||process_id==3){
    var url="{:url('show/wupin_index')}?bid="+id+"&process_id="+process_id;
}else if(process_id==4){
    var url="{:url('show/bl_index_index')}?bid="+id+"&process_id="+process_id;
}
else{
    var url="{:url('show/edit_assist')}?bid="+id+"&process_id="+process_id;
}

跳转到的控制器进行接收URL

$process_id=request()->get("process_id");
$bid=request()->get("bid");
