# dify-client
A Dify App Service-API Client, using for build a webapp by request Service-API
## Usage
First, install `dify-client` python sdk package:
```
pip install dify-client
```
Write your code with sdk:
- completion generate with `blocking` response_mode
```python
from dify_client import CompletionClient
api_key = "your_api_key"
# Initialize CompletionClient
completion_client = CompletionClient(api_key)
# Create Completion Message using CompletionClient
completion_response = completion_client.create_completion_message(inputs={"query": "What's the weather like today?"},
response_mode="blocking", user="user_id")
completion_response.raise_for_status()
result = completion_response.json()
print(result.get('answer'))
```
- completion using vision model, like gpt-4-vision
```python
from dify_client import CompletionClient
api_key = "your_api_key"
# Initialize CompletionClient
completion_client = CompletionClient(api_key)
files = [{
"type": "image",
"transfer_method": "remote_url",
"url": "your_image_url"
}]
# files = [{
# "type": "image",
# "transfer_method": "local_file",
# "upload_file_id": "your_file_id"
# }]
# Create Completion Message using CompletionClient
completion_response = completion_client.create_completion_message(inputs={"query": "Describe the picture."},
response_mode="blocking", user="user_id", files=files)
completion_response.raise_for_status()
result = completion_response.json()
print(result.get('answer'))
```
- chat generate with `streaming` response_mode
```python
import json
from dify_client import ChatClient
api_key = "your_api_key"
# Initialize ChatClient
chat_client = ChatClient(api_key)
# Create Chat Message using ChatClient
chat_response = chat_client.create_chat_message(inputs={}, query="Hello", user="user_id", response_mode="streaming")
chat_response.raise_for_status()
for line in chat_response.iter_lines(decode_unicode=True):
line = line.split('data:', 1)[-1]
if line.strip():
line = json.loads(line.strip())
print(line.get('answer'))
```
- chat using vision model, like gpt-4-vision
```python
from dify_client import ChatClient
api_key = "your_api_key"
# Initialize ChatClient
chat_client = ChatClient(api_key)
files = [{
"type": "image",
"transfer_method": "remote_url",
"url": "your_image_url"
}]
# files = [{
# "type": "image",
# "transfer_method": "local_file",
# "upload_file_id": "your_file_id"
# }]
# Create Chat Message using ChatClient
chat_response = chat_client.create_chat_message(inputs={}, query="Describe the picture.", user="user_id",
response_mode="blocking", files=files)
chat_response.raise_for_status()
result = chat_response.json()
print(result.get("answer"))
```
- upload file when using vision model
```python
from dify_client import DifyClient
api_key = "your_api_key"
# Initialize Client
dify_client = DifyClient(api_key)
file_path = "your_image_file_path"
file_name = "panda.jpeg"
mime_type = "image/jpeg"
with open(file_path, "rb") as file:
files = {
"file": (file_name, file, mime_type)
}
response = dify_client.file_upload("user_id", files)
result = response.json()
print(f'upload_file_id: {result.get("id")}')
```
- Others
```python
from dify_client import ChatClient
api_key = "your_api_key"
# Initialize Client
client = ChatClient(api_key)
# Get App parameters
parameters = client.get_application_parameters(user="user_id")
parameters.raise_for_status()
print('[parameters]')
print(parameters.json())
# Get Conversation List (only for chat)
conversations = client.get_conversations(user="user_id")
conversations.raise_for_status()
print('[conversations]')
print(conversations.json())
# Get Message List (only for chat)
messages = client.get_conversation_messages(user="user_id", conversation_id="conversation_id")
messages.raise_for_status()
print('[messages]')
print(messages.json())
# Rename Conversation (only for chat)
rename_conversation_response = client.rename_conversation(conversation_id="conversation_id",
name="new_name", user="user_id")
rename_conversation_response.raise_for_status()
print('[rename result]')
print(rename_conversation_response.json())
```
