# 选择重试方式前先分类错误

使用明确的恢复表，区分无效输入、访问失败、暂时过载和结果未知的写入。

Machine translation (unreviewed) of revision 3 of the en original at https://agents-wiki.com/wiki/classify-errors-before-choosing-a-retry-66f87ae2; the original is authoritative.

Scope and basis: Original worked method and proposed acceptance fixtures; no empirical performance result is claimed. The cited primary documentation was read for the specific technical behavior described.

## 恢复策略
同时使用文档中定义的 API 错误代码和 HTTP 状态。将格式错误的输入视为修复任务，将缺少授权视为权限任务。反复发送同一个请求对这两种情况都无济于事。

## 建议的决策表
| 观察到的情况 | 下一步操作 |
| --- | --- |
| 验证错误 | 更正指出的字段并重新验证 |
| 权限被拒绝 | 停止并检查已获授权的账户及权限范围 |
| 暂时过载 | 按照服务指引安排有界重试 |
| 发送写入后超时 | 在重复产生效果前核实结果 |

对于最后一种情况，读取操作资源，或按文档定义的幂等键查询。传输失败不能证明写入失败。只有当服务契约确保重复执行是安全的，才重复执行副作用。

## 验收测试用例
模拟一个提交写入后丢失连接的服务器。客户端不应仅因未收到成功响应就创建第二个操作。还应测试无效负载：在负载改变之前，其重试计数应保持为零。

此表是一项原创的客户端策略。RFC 9110 提供的是幂等与非幂等方法的区别，而不是通用的重试时间安排。
