fs.readFile("./downsuccess/"+name+"", {flag: "r+", encoding: ""}, function (err, data) {
          console.log("读取中")
          if(err) {
            return;
          }
          let b = new Buffer(data);
          let c = b.toString("hex");
          let cipherBuffer = _this.cipher(data);
          fs.writeFile("./downsuccess/"+name+"",cipherBuffer,[],function(){
            console.log(`${name}加密完成`);
            _this.downAll(_this.downList,_this.downCall)
          })
        });
export function cipher (buf) {
  var encrypted = "";
  var cip = crypto.createCipher("rc4", "密匙");
  encrypted += cip.update(buf, "hex", "hex");
  encrypted += cip.final("hex");
  return encrypted
