標準ライブラリのurllibか、サードパーティライブラリのRequestsを使う方法があるが、urllibの方でやってみる。

GET

get.py
import urllib.request
import json

url = 'https://petstore.swagger.io/v2/store/inventory'

try:
    with urllib.request.urlopen(url) as response:
        body = json.loads(response.read())
        headers = response.getheaders()
        status = response.getcode()

        print(headers)
        print(status)
        print(body)

except urllib.error.URLError as e:
     print(e.reason)

POST

post.py
import urllib.request
import json

url = 'https://petstore.swagger.io/v2/store/order'
req_header = {
    'Content-Type': 'application/json',
}
req_data = json.dumps({
  'id': 0,
  'petId': 0,
  'quantity': 0,
  'shipDate': '2020-04-10T10:11:13.419Z',
  'status': 'placed',
  'complete': True,
})

req = urllib.request.Request(url, data=req_data.encode(), method='POST', headers=req_header)

try:
    with urllib.request.urlopen(req) as response:
        body = json.loads(response.read())
        headers = response.getheaders()
        status = response.getcode()

        print(headers)
        print(status)
        print(body)

except urllib.error.URLError as e:
     print(e.reason)
