Compiling Code

Read Compilation Result

Introduction

Read a compile packet job result.

Request

Read a compile result for a specific Project Id and Compile Id. The /compile/read API accepts requests in the following format:

ReadCompileRequest Model - Request to read a compile packet job.
projectId integer
required
example: 23456789
Project Id we sent for compile.
compileId string
required
example: c0edc6-49048b
Compile Id returned during the creation request.
Example 
{
  "projectId": 23456789,
  "compileId": "c0edc6-49048b"
}

Responses

The /compile/read API provides a response in the following format:

200 Success

CompileResponse Model - Response from the compiler on a build event.
compileId string
example: c0edc6-49048b
Compile Id for a sucessful build.
state string Enum
True on successful compile. Options : ['InQueue', 'BuildSuccess', 'BuildError']
projectId integer
example: 23456789
Project Id we sent for compile.
signature string
Signature key of compilation.
signatureOrder string Array
Signature order of files to be compiled.
logs string Array
Logs of the compilation request.
success boolean
Indicate if the API request was successful.
errors string Array
List of errors with the API call.
Example 
{
  "compileId": "c0edc6-49048b",
  "state": "InQueue",
  "projectId": 23456789,
  "signature": "string",
  "signatureOrder": [
    "string"
  ],
  "logs": [
    "string"
  ],
  "success": true,
  "errors": [
    "string"
  ]
}

401 Authentication Error

UnauthorizedError Model - Unauthorized response from the API. Key is missing, invalid, or timestamp is too old for hash.
www_authenticate string
Header

Examples

The following example demonstates creating, and reading a compilation job through the cloud API.

from base64 import b64encode
from hashlib import sha256
from time import time
from requests import get, post
BASE_URL = 'https://www.quantconnect.com/api/v2/'

# You need to replace these with your actual credentials.
# You can request your credentials at https://www.quantconnect.com/settings/
# You can find our organization ID at https://www.quantconnect.com/organization/ 
USER_ID = 0
API_TOKEN = '____'
ORGANIZATION_ID = '____'

def get_headers():
    # Get timestamp
    timestamp = f'{int(time())}'
    time_stamped_token = f'{API_TOKEN}:{timestamp}'.encode('utf-8')

    # Get hased API token
    hashed_token = sha256(time_stamped_token).hexdigest()
    authentication = f'{USER_ID}:{hashed_token}'.encode('utf-8')
    authentication = b64encode(authentication).decode('ascii')

    # Create headers dictionary.
    return {
        'Authorization': f'Basic {authentication}',
        'Timestamp': timestamp
    }

# Authenticate to verify credentials
response = post(f'{BASE_URL}/authenticate', headers = get_headers())
print(response.json())

# --------------------


# The project ID of the project to compile
project_id = 12345678

### Create Compilation Job
# Prepare data payload to create a compilation job
payload = {
    "projectId": project_id  # ID of the project to compile
}
# Send a POST request to the /compile/create endpoint to start compilation
response = post(f'{BASE_URL}/compile/create', headers=get_headers(), json=payload)
# Parse the JSON response into python managable dict
result = response.json()
# Extract the compile ID from the response
compile_id = result['compileId']
# Check if the request was successful and print the result
if result['success']:
    print("Compilation Job Created Successfully:")
    print(result)

### Read Compilation Result
# Prepare data payload to read compilation result
payload = {
    "projectId": project_id,  # ID of the project
    "compileId": compile_id  # ID of the compilation job
}
# Send a POST request to the /compile/read endpoint to get compilation result
response = post(f'{BASE_URL}/compile/read', headers=get_headers(), json=payload)
# Parse the JSON response into python managable dict
result = response.json()
# Check if the request was successful and print the result
if result['success']:
    print("Compilation Result:")
    print(result)
