Infobip
此笔记本展示了如何使用 Infobip API 包装器发送短信和电子邮件。
Infobip 提供了许多服务，但此笔记本将重点关注短信和电子邮件服务。您可以在 此处 找到有关 API 和其他渠道的更多信息。
设置
要使用此工具，您需要拥有 Infobip 帐户。您可以创建 免费试用帐户。
InfobipAPIWrapper 使用命名参数，您可以在其中提供凭据
infobip_api_key- API 密钥，您可以在您的 开发者工具 中找到infobip_base_url- Infobip API 的基本 URL。您可以使用默认值https://api.infobip.com/。
您也可以将 infobip_api_key 和 infobip_base_url 作为环境变量 INFOBIP_API_KEY 和 INFOBIP_BASE_URL 提供。
发送短信
from langchain_community.utilities.infobip import InfobipAPIWrapper
infobip: InfobipAPIWrapper = InfobipAPIWrapper()
infobip.run(
to="41793026727",
text="Hello, World!",
sender="Langchain",
channel="sms",
)

发送电子邮件
from langchain_community.utilities.infobip import InfobipAPIWrapper
infobip: InfobipAPIWrapper = InfobipAPIWrapper()
infobip.run(
to="[email protected]",
sender="[email protected]",
subject="example",
body="example",
channel="email",
)

)
agent_executor.invoke(
{
"input": "Hi, can you please send me an example of Python recursion to my email [email protected]"
}
)

Invoking: `infobip_email` with `{'body': 'Hi,\n\nHere is a simple example of a recursive function in Python:\n\n```\ndef factorial(n):\n if n == 1:\n return 1\n else:\n return n * factorial(n-1)\n```\n\nThis function calculates the factorial of a number. The factorial of a number is the product of all positive integers less than or equal to that number. The function calls itself with a smaller argument until it reaches the base case where n equals 1.\n\nBest,\nCoding Teacher', 'to': '[email protected]', 'sender': '[email protected]', 'subject': 'Python Recursion Example', 'channel': 'email'}`
I have sent an example of Python recursion to your email. Please check your inbox.
