常见问题

收到“禁止访问”错误。（即使刷新后，整个页面仍显示“禁止访问”）
- API 添加速度过快可能会导致您达到 API 的速率限制。（我的测试是在 10 页之后进行的，所以大约有 10k 个项目）。
- 等待约 10-20 分钟后继续。加载https://quixel.comCommon Fixes -> Restart script后请参阅继续执行。
脚本似乎已暂停/挂起
- 可能是日志记录太多了。尝试监控脚本，如果显示“END PAGE X”，记下页码（以备需要重新启动）并通过单击 devtools 中的“🚫”图标清除控制台。
- 参见Common Fixes -> Restart script修复。
获取错误**UNABLE TO ADD ITEM**
- 应该会有中显示的错误信息( )。如果是user already owns specified asset at a higher or equal resolution，则它已在您的帐户中。
获取错误cannot find authentication token. Please login again
- 清除浏览器 cookies 并重新登录 quixel。尝试手动添加 1 个项目。如果成功，则查看Common Fixes -> Restart script是否继续执行。

常见修复

重启脚本

注意它正在运行哪个页面
复制run.js脚本
startPage = 0将第一行更新为startPage = 10（假设第 10 页被挂起）

变更日志

初始脚本发布
更新以清除日志，减少卡住的机会
[当前] 跳过已获取的项目。减少日志输出。脚本完成后增加更多显示信息，显示已购买项目的数量。由于现在跳过了已购买的项目，实际上您不再需要指定开始页面。
