A Python client for the Dify API
Project description
Dify API Python
Dify API Python is a Python implementation for interacting with Dify's API. It provides an easy-to-use interface for making API calls, with support for both streaming and non-streaming responses. The library also includes a method to merge stream responses, making it convenient to use in scenarios where streaming is not well supported.
Installation
Install the package using pip:
pip install dify-api-python
Usage
Importing the Client
from dify_api_python import DifyClient
Initializing the Client
You can initialize the DifyClient in several ways:
-
Using parameters:
client = DifyClient(api_key='your_api_key', base_url='https://api.dify.ai/v1')
-
Using a default configuration file:
client = DifyClient()
-
Using a custom configuration file:
client = DifyClient(config_path='/path/to/your/config.ini')
The configuration file should be in INI format and include the following:
[DEFAULT]
API_KEY = your_api_key
BASE_URL = https://api.dify.ai/v1
Note: If you provide api_key or base_url as parameters, they will override any values in the configuration file.
Making API Calls
Chat Completion
For a chat completion request:
response = client.chat_completion(
query="Hello, how are you?",
user="user123",
inputs={},
stream=False
)
print(response)
For a streaming chat completion:
for chunk in client.chat_completion(
query="Tell me a story",
user="user123",
inputs={},
stream=True
):
print(chunk)
Text Completion
For a text completion request:
response = client.text_completion(
prompt="Once upon a time",
user_id="user123",
inputs={},
stream=False
)
print(response)
For a streaming text completion:
for chunk in client.text_completion(
prompt="Write a poem about",
user_id="user123",
inputs={},
stream=True
):
print(chunk)
Combined Chat Completion
For a combined chat completion (merges streaming response):
response = client.chat_completion_combined(
query="Explain quantum computing",
user="user123",
inputs={}
)
print(response)
Example Usage
Here's a complete example of how to use the Dify API Python client:
from dify_api_python import DifyClient
# Initialize DifyClient
client = DifyClient(api_key='your_api_key', base_url='https://api.dify.ai/v1')
def chat_with_dify(query, user_id="user123", inputs={}):
"""
Chat with Dify API
:param query: User's question or input
:param user_id: User ID, default is "user123"
:param inputs: Additional input parameters, default is an empty dictionary
:return: API response
"""
try:
response = client.chat_completion_combined(
query=query,
user=user_id,
inputs=inputs
)
return response
except Exception as e:
print(f"An error occurred: {str(e)}")
return None
# Example usage
if __name__ == "__main__":
user_query = "Please explain the basic principles of quantum computing"
result = chat_with_dify(user_query)
if result:
print("Dify's answer:")
print(result)
else:
print("Failed to get an answer")
Key Features
- Flexible client initialization (via parameters or config file)
- Support for both streaming and non-streaming API calls
- Method to merge streaming responses
- Easy-to-use interface for chat and text completions
