控制台输入以下代码

$.ajax({
type: "POST",
url: "/api/sharedownload?sign="+yunData.SIGN+"&timestamp="+yunData.TIMESTAMP,
data: "encrypt=0&product=share&uk="+yunData.SHARE_UK+"&primaryid="+yunData.SHARE_ID+"&fid_list=%5B"+yunData.FS_ID+"%5D",
dataType: "json",
success: function(d){
window.location.href = d.list[0].dlink;
}
});
