import requests

response = requests.post('http://httpbin.org/post', data={'key1': 'value1'})
print(response.request.url)
print(response.request.body)
print(response.request.headers)

响应对象有一个.request属性，它是被发送的PreparedRequest对象。

import requests

response = requests.post('http://httpbin.org/post', data={'key1': 'value1'})
print(response.request.url)
print(response.request.body)
print(response.request.headers)

响应对象有一个.request属性，它是被发送的PreparedRequest对象。

更好的想法是使用requests_toolbelt库，它可以将请求和响应都转储为字符串，以便打印到控制台。它处理了上面的解决方案不能很好处理的文件和编码的所有棘手情况。

其实很简单:

import requests
from requests_toolbelt.utils import dump

resp = requests.get('https://httpbin.org/redirect/5')
data = dump.dump_all(resp)
print(data.decode('utf-8'))

来源:https://toolbelt.readthedocs.org/en/latest/dumputils.html

你可以通过输入:

pip install requests_toolbelt

下面是一个代码，它是相同的，但有响应头:

import socket
def patch_requests():
    old_readline = socket._fileobject.readline
    if not hasattr(old_readline, 'patched'):
        def new_readline(self, size=-1):
            res = old_readline(self, size)
            print res,
            return res
        new_readline.patched = True
        socket._fileobject.readline = new_readline
patch_requests()

我花了很长时间找这个，所以我把它留在这里，如果有人需要的话。

我使用以下函数格式化请求。它类似于@AntonioHerraizS，只不过它也会在主体中漂亮地打印JSON对象，并且它标记了请求的所有部分。

format_json = functools.partial(json.dumps, indent=2, sort_keys=True)
indent = functools.partial(textwrap.indent, prefix='  ')

def format_prepared_request(req):
    """Pretty-format 'requests.PreparedRequest'

    Example:
        res = requests.post(...)
        print(format_prepared_request(res.request))

        req = requests.Request(...)
        req = req.prepare()
        print(format_prepared_request(res.request))
    """
    headers = '\n'.join(f'{k}: {v}' for k, v in req.headers.items())
    content_type = req.headers.get('Content-Type', '')
    if 'application/json' in content_type:
        try:
            body = format_json(json.loads(req.body))
        except json.JSONDecodeError:
            body = req.body
    else:
        body = req.body
    s = textwrap.dedent("""
    REQUEST
    =======
    endpoint: {method} {url}
    headers:
    {headers}
    body:
    {body}
    =======
    """).strip()
    s = s.format(
        method=req.method,
        url=req.url,
        headers=indent(headers),
        body=indent(body),
    )
    return s

我有一个类似的函数来格式化响应:

def format_response(resp):
    """Pretty-format 'requests.Response'"""
    headers = '\n'.join(f'{k}: {v}' for k, v in resp.headers.items())
    content_type = resp.headers.get('Content-Type', '')
    if 'application/json' in content_type:
        try:
            body = format_json(resp.json())
        except json.JSONDecodeError:
            body = resp.text
    else:
        body = resp.text
    s = textwrap.dedent("""
    RESPONSE
    ========
    status_code: {status_code}
    headers:
    {headers}
    body:
    {body}
    ========
    """).strip()

    s = s.format(
        status_code=resp.status_code,
        headers=indent(headers),
        body=indent(body),
    )
    return s
