Python实现接口签名调用

1、第三方接口签名调用

import json
import requests
import hashlib
import time
import hmac
access_key = 'xxxxxxxxxxxxxxx'
secret_key = 'xxxxxxxxxxxxxxx'
# 应用信息
def _wps4_sig(method, url, date, body):

    if body is None:
        bodySha = ""
    else:

    content = "xxx-4" + method + url + "application/json" + date + bodySha
    print(content)
    signature = hmac.new(secret_key.encode('utf-8'), content.encode('utf-8'), hashlib.sha256).hexdigest()

    return "xxx-4 %s:%s" % (access_key, signature)

    requests.packages.urllib3.disable_warnings()

    if body is not None and not isinstance(body, str):

    header['xxx-Docs-Date'] = date
    header['xxx-Docs-Authorization'] = _wps4_sig(method, uri, date, body)

    if headers != None:
        # header = {}
        for key, value in headers.items():
            header[key] = value

    url = "%s%s" % (host, uri)
    r = requests.request(method, url, data=body,
                         headers=header, cookies=cookie, verify=False)

    print(result[0])
    print(result[1])
edit()
