Question

我正在尝试实现简单的api客户端并面临非常具体的问题。试图在平面python代码中做一些简单的请求就可以了。但是，当我尝试将其全部包装到一个小类中时，它会返回一个带有403状态代码的响应。我尝试了不同的方法来解决这个问题，但到目前为止还没有。

Snippet＃1

import requests
import hashlib
import time

api_key = "my_api_key"
secret = "my_secret"
endpoint = "https://somecompany.com/some-api/1.0/status"

s = requests.Session()
s.headers['Accept'] = "application/json"
s.headers['Api-Key'] = api_key

def encode_signature(api_key, secret, time_secs):
    return hashlib.sha256(
        "{}{}{}".format(api_key, secret, time_secs)
        ).hexdigest()

def test_req(method, url, api_key, signature, **kwargs):
    r = requests.Request(method=method, url=url, **kwargs)
    prepped = s.prepare_request(r)
    prepped.headers['X-Signature'] = signature
    resp = s.send(prepped)
    return resp, prepped

if __name__ == '__main__':
    resp, req = test_req('GET', endpoint, api_key,
                         encode_signature(api_key, secret, int(time.time())))
    print resp.status_code

Snippet＃2（这个不起作用，但看起来和我类似）

import requests
import hashlib
import time

api_key = "my_api_key"
secret = "my_secret"
endpoint = "https://somecompany.com/some-api/1.0/status"

class Transport(object):
    """docstring for Transport"""
    def __init__(self, api_key, secret):
        self.api_key = api_key
        self.secret = secret
        self.conn = requests.Session()
        self.conn.headers['Api_Key'] = api_key
        self.conn.headers['Accept'] = 'application/json'

    @property
    def signature(self):
        return hashlib.sha256(
        "{}{}{}".format(self.api_key, self.secret, int(time.time()))
        ).hexdigest()

    def request(self, method, endpoint, **kwargs):
        r = requests.Request(method=method, url=endpoint, **kwargs)
        prepped = self.conn.prepare_request(r)
        prepped.headers['X-Signature'] = self.signature
        resp = self.conn.send(prepped)
        return resp, prepped

if __name__ == '__main__':
    tr = Transport(api_key, secret)
    resp, req = tr.request('GET', endpoint)
    print resp.status_code

正如我所想，我用这两个片段做了完全相同的事情只有区别：在session属性中存储会话而不是全局变量。有没有办法处理会话对象错误？我迫切需要帮助！
