我正在通过 REST API 进行操作。两个问题

1）我想将一些现有数据推送到 Quickblox 自定义对象。我需要多少个 REST 调用？（我不太清楚涉及计算机安全的整个事件状态。）是否首先（a）获取会话令牌。然后就按照在这里创建新记录？

2）我正在尝试获取会话令牌，但我得到{"errors":{"base":["Unexpected signature"]}}了响应。这是我生成随机数、签名和获取会话令牌的代码：

# Of course these are not really 0, x, and y's.
appId = '0000'
authKey = 'XXXXXXXXXXX'
authSecret = 'YYYYYYYYYYYYYY'

def getNonce():
    import random
    return random.random()

def createSignature(nonce):
    import hashlib
    import hmac
    import binascii
    import time
    stringForSignature = 'application_id={id}&auth_key={auth_key}&nonce={nonce}&timestamp={timestamp}'.format(id=appId,
                           auth_key=authKey, nonce=nonce, timestamp=time.time())
    hmacObj = hmac.new(authKey, stringForSignature, hashlib.sha1)
    return binascii.b2a_base64(hmacObj.digest())[:-1] # -1 to get rid of \n

def getSessionToken():
    import time
    epoch = "%s" % int(time.time())
    nonce = getNonce()
    params = {'application_id': appId,
                    'auth_key': authKey,
                   'timestamp': epoch,
                       'nonce': nonce,
                   'signature': createSignature(nonce)}
    jsonData = json.dumps(params)

    httpHeaders = {'Content-Type': 'application/json',
                   'QuickBlox-REST-API-Version': '0.1.0'}

    r = requests.post('https://api.quickblox.com/session.json', data=jsonData, headers = httpHeaders)
    print 'status code:', r.status_code
    responseJson = r.text
    print responseJson
    response = json.loads(responseJson)

getSessionToken()

我想这是导致问题的生成签名的方式？

这是我的问题的答案。事实证明，timestamp 应该只是整数，hamc 应该使用密钥，并且应该使用https://api.quickblox.com/auth.json而不是 session。而且我没有为我的签名使用正确的编码。

我在您的代码中发现了以下问题：

  • 功能。RANDOM - 我们需要整数值（不在 0 和 1 之间）
  • 功能。时间戳。您计算“时间戳”两次。最好使用一次“时间戳”
  • (def createSignature) - 正如您已经知道的那样......您的代码使用了其他算法，而不是我们需要的。

我建议您使用以下代码，上面的错误已被修改。结果，您将获得以下身份验证： --------- 请求 ------------------------------- - --------- 请求用户授权 --------- --------- 请求设备参数 ----------
