如何检查对象中是否存在对象

const obj = {
  key1: 'value1',
  key2: 'value2'
};

if (obj.hasOwnProperty('key1')) {
  console.log('key1 exists');
} else {
  console.log('key1 does not exist');
}

kubectl get pods

from tencentcloud.common import credential
from tencentcloud.cos.v20180528 import cos_client, models

cred = credential.Credential("secretId", "secretKey")
client = cos_client.CosClient(cred, "ap-shanghai")

req = models.HeadObjectRequest()
req.Bucket = "mybucket"
req.Key = "myobject"

try:
    resp = client.HeadObject(req)
    print("Object exists")
except Exception as e:
    print("Object does not exist")
