| 四、进阶任务 |
| |
| import requests |
| |
| |
| |
| def http_post(url, js): |
| |
| headers = {'Content-Type': 'application/json'} |
| |
| resp = requests.post(url, jstr, headers=headers) |
| |
| print(resp.content) |
| |
| |
| |
| |
| |
| if name == 'main': |
| |
| url = 'http://localhost:8080/stats/flowentry/add' |
| |
| for i in range(1, 9): |
| |
| ​ with open('%s.json' % i) as f: |
| |
| ​ jstr = f.read() |
| |
| ​ http_post(url, jstr) |
| |
