# 撰寫 SQLmap tamper 參數繞過腳本
### 腳本基本結構

#!/usr/bin/env python

def dependencies():
    pass

def tamper(payload, **kwargs):
    # have some code...
    return payload

### 簡易範例
假設寫一個叫做 test123<!-- -->.py 的腳本

#!/usr/bin/env python

# 如果使用此腳本的dbms不是mysql或mssql，就顯示警告訊息
def dependencies():
    from lib.core.enums import DBMS
    if conf.dbms not in [DBMS.MYSQL, DBMS.MSSQL]:
        logger.warn("This tamper script is mainly intended for MySQL or MSSQL.")

        
# 假設=被過濾，但是like沒被過濾
def tamper(payload, **kwargs):
    if payload:
        payload=payload.replace('=',' like ')
    return payload

寫完後把腳本放到 sqlmap 裡有個 tamper 資料夾，丟進入後，加上參數 `--tamper test123` 即可
