Simple Log Service:Panduan Cepat Mulai SDK Python

Buat file SLSQuickStart.py. Skrip ini membuat proyek, Logstore, dan indeks, menulis log, lalu menjalankan kueri:

from aliyun.log import LogClient, PutLogsRequest, LogItem, GetLogsRequest, IndexConfig
import time
import os

# Contoh ini mengambil ID AccessKey dan Secret AccessKey dari variabel lingkungan.
accessKeyId = os.environ.get('ALIBABA_CLOUD_ACCESS_KEY_ID', '')
accessKey = os.environ.get('ALIBABA_CLOUD_ACCESS_KEY_SECRET', '')
# Titik akhir untuk Simple Log Service. Contoh ini menggunakan titik akhir untuk wilayah China (Hangzhou). Ganti dengan titik akhir aktual Anda.
endpoint = "cn-hangzhou.log.aliyuncs.com" 

# Buat client Simple Log Service. 
client = LogClient(endpoint, accessKeyId, accessKey)

# Nama proyek.
project_name = "aliyun-test-project"
# Nama Logstore.
logstore_name = "aliyun-test-logstore"
# Pernyataan kueri.
query = "*| select dev,id from " + logstore_name
# Konfigurasi indeks.
