Connect with Dify via Custom Tool

[taowang1993]

Hi, I deployed both Flowise and Dify.

Both are awesome work, and each differs in strength.

Is it possible to create a connection between Flowise and Dify? Like this?

I tried the following code to create the custom tool, but it did not work.

const fetch = require('node-fetch');

// Dify API environment variables
const APP_ID = "xxxxxxxxxx";
const APP_KEY = "xxxxxxxxxxx";
const API_URL = "xxxxxxxxxxx";

// Flowise custom tool
module.exports = async function(context) {
try {
// Extract the required parameters from the context
const { query, user, files } = context.input;

// Prepare the API request body
const requestBody = {
  inputs: {},
  query: query,
  response_mode: 'streaming',
  conversation_id: '',
  user: user,
  files: files
};

// Make the API request to Dify
const response = await fetch(`${API_URL}/chat-messages`, {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${APP_KEY}`,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify(requestBody)
});

// Check if the request was successful
if (!response.ok) {
  throw new Error(`API request failed with status code ${response.status}`);
}

// Stream the response from Dify
const data = await response.json();
return data;

} catch (error) {
console.error('Error occurred while fetching data from Dify:', error);
return { error: error.message };
}
};

Here is Dify API reference

curl -X POST 'https://api.dify.ai/v1/chat-messages'
--header 'Authorization: Bearer {api_key}'
--header 'Content-Type: application/json'
--data-raw '{
"inputs": {},
"query": "What are the specs of the iPhone 13 Pro Max?",
"response_mode": "streaming",
"conversation_id": "",
"user": "abc-123",
"files": [
{
"type": "image",
"transfer_method": "remote_url",
"url": "https://cloud.dify.ai/logo/logo-site.png"
}
]
}'
