Overview

This document describes how to batch apply for and download certificates using Tencent Cloud APIs.

Preparations

Create a sub-account and authorize it with all permissions associated with cloud APIs and SSL certificates.
Install the latest version of Python. Download the package via here if necessary.
Install the latest version of PyCharm. Download it via here if necessary.
Note:
To keep your account and cloud assets under it secure, properly keep and regularly update SecretId and SecretKey.
Create a sub-account as instructed in Creating and Authorizing Sub-account.

Directions

1. Open the command prompt window and view the Python script with the following command:
python -V
2. View installed third-party modules for Python with the following command:
pip list

Note:
For example, if requests is missing, install it with pip install requests.
3. Use pip to install Tencent Cloud Python SDK with the following command:
pip install -i https://mirrors.tencent.com/pypi/simple/ --upgrade tencentcloud-sdk-python
4. Download the latest code from Github repository or Gitee repository and decompress it.
5. Open PyCharm, import the latest code file, create a new .py file under the tencentcloud-sdk-python/tencentcloud/ssl directory, such as apply.py, add the following code in the file and run.
import json,base64
from time import time,sleep
from tencentcloud.common import credential
from tencentcloud.common.profile.client_profile import ClientProfile
from tencentcloud.common.profile.http_profile import HttpProfile
from tencentcloud.common.exception.tencent_cloud_sdk_exception import TencentCloudSDKException
from tencentcloud.ssl.v20191205 import ssl_client, models

start = time()
#SecretId: Your API SecretID; SecretKey: Your API SecretKey.
cred = credential.Credential("SecretId", "SecretKey")
httpProfile = HttpProfile()
httpProfile.endpoint = "ssl.tencentcloudapi.com"
clientProfile = ClientProfile()
clientProfile.httpProfile = httpProfile
domain_name = []
while True:
 domain = input('the domain for which a certificate is applied')#Enter the domain to be bound with the certificate you are applying for; if you don’t want to continue, press Enter.
 if domain == '':
     break
 else:
     domain_name.append(domain)

for i in range(len(domain_name)):
 client = ssl_client.SslClient(cred, "", clientProfile)
 try:

     req = models.ApplyCertificateRequest()
     params = {
         "DvAuthMethod": "DNS_AUTO",
         "DomainName": domain_name[i]
     }
     req.from_json_string(json.dumps(params))

     resp = client.ApplyCertificate(req)
     response = json.loads(resp.to_json_string())
     print('domain: {0}material submitted, auto-verification in 5s'.format(domain_name[i]))
     certid = response['CertificateId']
     sleep(5)
     try:
         req1 = models.CompleteCertificateRequest()
         params1 = {
             "CertificateId": certid
         }
         req1.from_json_string(json.dumps(params1))

         resp1 = client.CompleteCertificate(req1)
         response1 = json.loads(resp1.to_json_string())
         print('doman: {0}verified successfully. Prepare to download the certificate'.format(domain_name[i]))
         try:
             req2 = models.DownloadCertificateRequest()
             params2 = {
                 "CertificateId": certid
             }
             req2.from_json_string(json.dumps(params2))

             resp2 = client.DownloadCertificate(req2)
             response2 = json.loads(resp2.to_json_string())
             # print(response2['Content'])
             content = response2['Content']
             with open("{0}.zip".format(domain_name[i]), "wb") as f:

                 f.write(base64.b64decode(content))
                 f.close()
         except TencentCloudSDKException as err:
             print(err)
     except TencentCloudSDKException as err:
         print(err)
 except TencentCloudSDKException as err:
     print(err)
end = time()
print('This code execution takes', round(end - start, 2), 's')

Result display

1. Apply for certificates in batches.
2. Download certificates.
