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：

3
4

6
7
8
9

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：

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)?
