问题
我们在开发过程中，为了快速验证接口，
经常采用postman或者Python代码先行验证的方式，确保接口正常，
在测试接口过程中偶尔会遇到接口异常，这时候要和打印完整的http请求，
帮助接口开发人员确认问题；
方法
仅仅是打印出这些信息，很简单：
|
1 2 3 4 |
import requests response = requests.post('http://httpbin.org/post', data={'key1':'value1'}) print(response.request.headers) print(response.request.body) |
或者：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
import requests
def pretty_print_POST(req): print('{}\n{}\r\n{}\r\n\r\n{}'.format( '-----------START-----------', req.method + ' ' + req.url, '\r\n'.join('{}: {}'.format(k, v) for k, v in req.headers.items()), req.body, ))
req = requests.Request('POST','http://stackoverflow.com',headers={'X-Custom':'Test'},data='a=1&b=2') prepared = req.prepare() pretty_print_POST(prepared)
s = requests.Session() resp = s.send(prepared) print(resp.text) |
但如果你想要在进行请求之前对http头和数据进行操作，也是使用prepare：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
from requests import Request, Session
s = Session()
req = Request('POST', url, data=data, headers=headers) prepped = req.prepare()
# do something with prepped.body prepped.body = 'No, I want exactly this as the body.'
# do something with prepped.headers del prepped.headers['Content-Type']
resp = s.send(prepped, stream=stream, verify=verify, proxies=proxies, cert=cert, timeout=timeout )
print(resp.status_code) |
python 的库的用法去对应的库的帮助文档里去找，更为方便些；
- Python requests - print entire http request (raw)?
