出现指定的状态码< RETRY_HTTP_CODES >时重试; 最大重试次数为< RETRY_TIMES >; 且重试请求可以调整优先级< RETRY_PRIORITY_ADJUST >; 默认不修改优先级
查看源码我们可以发现,对于返回http code的response,该中间件会通过process_response方法来处理,处理办法比较简单,判断response.status是否在retry_http_codes集合中,这个集合是读取的配置文件: RETRY_ENABLED = True # 默认开启失败重试,一般关闭 RETRY_TIMES = 3 # 失败后重试次数,默认两次 RETRY_HTTP_CODES = [500...
RETRY_HTTP_CODES Default: [500, 502, 503, 504, 522, 524, 408, 429] Which HTTP response codes to retry. Other errors (DNS lookup issues, connections lost, etc) are always retried. In some cases you may want to add 400 to RETRY_HTTP_CODES because it is a common code used to indica...
