ajax.send("aid=2608&avatar=https://p9-juejin.byteimg.com/tos-cn-i-k3u1fbpfcp/a6f9e062e170420a8bef906fd117729e~tplv-k3u1fbpfcp-zoom-in-crop-mark:1512:0:0:0.awebp?"); 
ajax.onreadystatechange = function (){ 
    if(ajax.readyState==4&&ajax.status==200){ 
    var c = ajax.responseText; 
    console.log(c)
