## 解决方案

1. **Wait for the rate limit window to expire (typically a few minutes).** (80% 成功率)
   ```
   Pause all Go commands for 5-10 minutes, then retry.
   ```
2. **Use a different proxy or direct source with GOPROXY=direct.** (90% 成功率)
   ```
   Set 'export GOPROXY=direct' to bypass the proxy and fetch directly from VCS.
   ```

## 无效尝试

- **Increasing parallelism in build with -p flag.** — More parallel requests will worsen the rate limit. (100% 失败率)
- **Using a different proxy without waiting.** — If the same IP is used, the rate limit may still apply. (50% 失败率)
