 ## 使用方法
 
 ```shell
-python main.py --cookie[ --epochs[ --tasks-num[ --requests-num[ --wait[ --wait-epoch[ --print]]]]]]
+python main.py --cookie[ --epochs[ --tasks-num[ --requests-num[ --wait[ --wait-epoch[ --out[ --proxy]]]]]]]
 ```
 
 ```shell
-python rank.py --cookie
+python rank.py --cookie[ --once]
 ```
 
 ## 参数
 
+main.py
+
 * `-c` `--cookie` cookie
 * `-e` `--epochs` 重复次数
 * `-tn` `--tasks-num` task数量
 * `-rn` `--requests-num` 单个task循环请求次数,最好不要超过1000
 * `-w` `--wait` 单个task中每次请求后等待时间(s)
 * `-we` `--wait-epoch` 每次循环后等待时间(s)
-* `-p` `--print` 是否打印报文(y/n)
+* `-o` `--out` 是否打印报文(y/n)
+* `-p` `--proxy` 设置代理,格式为"ip:port"
+
+rank.py
+
+- `-c` `--cookie` cookie,同main.py
+- `-o` `--once` 只获取一次排名(y/n)
