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。
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。
