 * `--form-keyword-values, -fkv` Customize the value of the form fill, set by keyword fuzzy match. The keyword matches the four attribute values of `id`, `name`, `class`, `type` of the input box label. For example, fuzzy match the pass keyword to fill 123456 and the user keyword to fill admin, `-fkv user=admin -fkv pass=123456`. (Default: Cralwergo)

 * `--filter-mode Mode, -f Mode`   过滤模式，简单：只过滤静态资源和完全重复的请求。智能：拥有过滤伪静态的能力。严格：更加严格的伪静态过滤规则。
 * `--output-mode value, -o value`   结果输出模式，`console`：打印当前域名结果。`json`：打印所有结果的json序列化字符串，可直接被反序列化解析。`none`：不打印输出。
 * `--output-json filepath` 将爬虫结果JSON序列化之后写入到json文件。
-* `--incognito-context, -i`   浏览器启动隐身模式
 * `--max-tab-count Number, -t Number`   爬虫同时开启最大标签页，即同时爬取的页面数量。
 * `--fuzz-path`  使用常见路径Fuzz目标，获取更多入口。
 * `--fuzz-path-dict`  通过字典文件自定义Fuzz目录，传入字典文件路径，如：`/home/user/fuzz_dir.txt`，文件每行代表一个要fuzz的目录。
