title: "REST" date: 2019-03-13T18:28:09-07:00 draft: false
Interact with the API server (e.g. submit a SQL query, list some S3 files in a bucket, search for a table...) with via a REST API.
Users authenticate with the same credentials as they would do in the Browser login page.
The API can be called directly via REST. Some calls, JavaScript and Python wrappers are not fully documented yet.
Default content type is form data, e.g.:
-H "Content-Type: application/x-www-form-urlencoded" -d 'username=demo&password=demo'
It is possible to submit data in JSON format:
-H "Content-Type: application/json" -d '{"username": "demo", "password": "demo"}'
Calling without credentials:
curl -X POST https://demo.gethue.com/api/query/create_notebook -H "Content-Type: application/json"
{"detail":"Authentication credentials were not provided."}
Authenticating and getting a JWT token:
curl -X POST https://demo.gethue.com/api/token/auth/ -H "Content-Type: application/json" -d '{"username": "demo", "password": "demo"}'

Re-using the token when making actual calls:

In this code snippet, we will use the requests library:
pip install requests
And then:
import json
import requests
session = requests.Session()
data = {
'username': 'demo',
'password': 'demo',
}
response = session.post("https://demo.gethue.com/api/token/auth", data=data)
print('Auth: %s %s' % ('success' if response.status_code == 200 else 'error', response.status_code))
token = json.loads(response.content)['access']
print('Token: %s' % token)
response = requests.post(
'https://demo.gethue.com/api/query/autocomplete',
headers={
'Authorization': 'Bearer %s' % token,
"Content-Type": "application/x-www-form-urlencoded"
},
data={'snippet': json.dumps({"type":"mysql"})}
)
print(response.status_code)
print(response.text)
In the meantime, with Axios:
<script src="https://unpkg.com/axios@0.21.1/dist/axios.min.js"></script>
<script type="text/javascript">
const API_URL = "https://demo.gethue.com";
axios.defaults.baseURL = API_URL;
axios.post('api/token/auth/', {username: "hue", password: "hue"}).then(function(data) {
console.log(data['data']);
// Util to check if cached token is still valid before asking to auth for a new one
axios.post('api/token/verify/', {token: data['access']});
axios.defaults.headers.common['Authorization'] = 'Bearer ' + data['access'];
}).then(function() {
axios.post('api/query/sqlite', {statement:"SELECT 1000, 1001"}).then(function(data) {
console.log(data['data']);
});
axios.post('api/connectors/types/').then(function(data) {
console.log(data['data']);
});
});
</script>
The API authenticates via the authentication backends of the server (same as going via the login page). This is consistent and users are free to interact via their browsers or API.
Then a JWT token is returned and needs to be passed as a bearer in the headers for all the API calls.
Wrong credentials: there is currently no error on bad authentication but instead a 302 redirect to the login page, e.g.:
curl -X POST https://demo.gethue.com/notebook/execute/v1/create_notebook -H "Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ0b2tlbl90eXBlIjoiYWNjZXNzIiwiZXhwIjoxNjIxNjM5NjMxLCJqdGkiOiI0NTY3NTA4MzM5YjY0MjFmYTMzZDJjMzViZWUyMDAyMCIsInVzZXJfaWQiOjF9.qrMNrr69eo38dOsV2aYp8k6WqBeyJZkbSuavxA_o_kM"

Provide login credentials and get a JWT token:

And keep the access tokent as the value of the bearer.
The validity (i.e. did it expire?) of an access token can be verified:
curl -X POST https://demo.gethue.com/api/token/verify/ -d 'token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ0b2tlbl90eXBlIjoiYWNjZXNzIiwiZXhwIjoxNjIxNjM4NTMxLCJqdGkiOiJhZjgwN2E0ZjBmZDI0ZWMxYWQ2NTUzZjEyMjIyYzU4YyIsInVzZXJfaWQiOjF9.dQ1P3hbzSytp9-o8bWlcOcwrdwRVy95M2Eolph92QMA'
Similarly, an access token validity can be extended via a refresh sending the refresh token obtained in the initial authentication.
curl -X POST https://demo.gethue.com/api/token/refresh/ -d 'refresh=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ0b2tlbl90eXBlIjoicmVmcmVzaCIsImV4cCI6MTYyMTcyNDYzMSwianRpIjoiOGM0NDRjYzRhN2VhNGMxZDliMGZhNmU1YzUyMjM1MjkiLCJ1c2VyX2lkIjoxfQ.t6t7_eYrNhpGN3-Jz5MDLXM8JtGP7V9Y9lacOTInqqQ'
Now that we are authenticated, here is how to execute a SHOW TABLES SQL query via the hive connector. You could repeat the steps with any query you want, e.g. SELECT * FROM web_logs LIMIT 100.
Selecting the Database to query via the dialect argument in /api/editor/execute/<dialect>:
For a SHOW TABLES, first we send the query statement:
curl -X POST https://demo.gethue.com/api/editor/execute/hive --data 'statement=SHOW TABLES'
{"status": 0, "history_id": 17880, "handle": {"statement_id": 0, "session_type": "hive", "has_more_statements": false, "guid": "EUI32vrfTkSOBXET6Eaa+A==\n", "previous_statement_hash": "3070952e55d733fb5bef249277fb8674989e40b6f86c5cc8b39cc415", "log_context": null, "statements_count": 1, "end": {"column": 10, "row": 0}, "session_id": 63, "start": {"column": 0, "row": 0}, "secret": "RuiF0LEkRn+Yok/gjXWSqg==\n", "has_result_set": true, "session_guid": "c845bb7688dca140:859a5024fb284ba2", "statement": "SHOW TABLES", "operation_type": 0, "modified_row_count": null}, "history_uuid": "63ce87ba-ca0f-4653-8aeb-e9f5c1781b78"}
Then check the operation (its value is history_uuid from the execute response) status until its result is ready to fetch:
curl -X POST https://demo.gethue.com/api/editor/check_status --data 'operationId=63ce87ba-ca0f-4653-8aeb-e9f5c1781b78'
{"status": 0, "query_status": {"status": "available", "has_result_set": true}}
And now ask for the resultset of the statement:
curl -X POST https://demo.gethue.com/api/editor/fetch_result_data --data 'operationId=63ce87ba-ca0f-4653-8aeb-e9f5c1781b78'
{"status": 0, "result": {"has_more": true, "type": "table", "meta": [{"comment": "from deserializer", "type": "STRING_TYPE", "name": "tab_name"}], "data": [["adavi"], ["adavi1"], ["adavi2"], ["ambs_feed"], ["apx_adv_deduction_data_process_total"], ["avro_table"], ["avro_table1"], ["bb"], ["bharath_info1"], ["bucknew"], ["bucknew1"], ["chungu"], ["cricket3"], ["cricket4"], ["cricket5_view"], ["cricketer"], ["cricketer_view"], ["cricketer_view1"], ["demo1"], ["demo12345"], ["dummy"], ["embedded"], ["emp"], ["emp1_sept9"], ["emp_details"], ["emp_sept"], ["emp_tbl1"], ["emp_tbl2"], ["empdtls"], ["empdtls_ext"], ["empdtls_ext_v2"], ["employee"], ["employee1"], ["employee_ins"], ["empppp"], ["events"], ["final"], ["flight_data"], ["gopalbhar"], ["guruhive_internaltable"], ["hell"], ["info1"], ["lost_messages"], ["mnewmyak"], ["mortality"], ["mscda"], ["myak"], ["mysample"], ["mysample1"], ["mysample2"], ["network"], ["ods_t_exch_recv_rel_wfz_stat_szy"], ["olympicdata"], ["p_table"], ["partition_cricket"], ["partitioned_user"], ["s"], ["sample"], ["sample_07"], ["sample_08"], ["score"], ["stg_t_exch_recv_rel_wfz_stat_szy"], ["stocks"], ["students"], ["studentscores"], ["studentscores2"], ["t1"], ["table_name"], ["tablex"], ["tabley"], ["temp"], ["test1"], ["test2"], ["test21"], ["test_info"], ["topage"], ["txnrecords"], ["u_data"], ["udata"], ["user_session"], ["user_test"], ["v_empdtls"], ["v_empdtls_ext"], ["v_empdtls_ext_v2"], ["web_logs"]], "isEscaped": true}}
And if we wanted to get the execution log for this statement:
curl -X POST https://demo.gethue.com/notebook/api/get_logs --data 'operationId=63ce87ba-ca0f-4653-8aeb-e9f5c1781b78'
{"status": 0, "progress": 5, "jobs": [], "logs": "", "isFullLogs": false}

Hue's File Browser offer uploads, downloads, operations (create, delete, chmod...) and listing of data in HDFS (hdfs:// or no prefix), S3 (s3a:// prefix), ADLS (adls:// or abfs:// prefixes) storages.

Then we submit via https://demo.gethue.com/indexer/api/importer/submit and provide the source and destination parameters. We get back an operation id (i.e. some SQL Editor query history id).
If the show_command parameter is given, the API call will instead return the generated SQL queries that will import the data.
