默认修改头像时如果上传的图片为png透明图片，生成的头像透明部分会变成黑色，修改了生成头像为png格式。可正常显示图片透明部分。

handleUpdate(row)方法中：this.form = response.data;语句
会导致【this.form.postIds = response.postIds;】和【this.form.roleIds = response.roleIds;】失效。
导致用户编辑对话框中，角色和部门多选框无法正常修改。
建议使用以下语句修改：
this.$set(this.form, "postIds", response.postIds);
this.$set(this.form, "roleIds", response.roleIds);
