Question

我一直在尝试使用httplib2 Http类向Twilio发出API请求，无论我如何尝试设置请求，它都不会发送我的帖子DATA。我知道这一点，因为我发布到本地URL并且帖子参数是空的。这是我的代码：

_TWILIO_URL = 'https://api.twilio.com/2010-04-01/Accounts/%s/%s'
class Api(object):
    '''
    A Python interface to the Twilio API
    '''

    def __init__(self, AccountSid, AuthToken, From):
        self.AccountSid = AccountSid
        self.AuthToken = AuthToken
        self.From = From

    def _get_from(self, From):
        """Use the provided From number or the one defined on initialization"""
        if From:
            return From
        else:
            return self.From

    def call(self, To, Url, From=None):
        """Sends a request to Twilio having it call a number; the provided URL will indicate how to handle the call"""
        url = _TWILIO_URL % (self.AccountSid, 'Calls')
        data = dict(From=self._get_from(From), To=To, Url=Url)
        return self.request(url, body=urlencode(data))

    def request(self, url, method='POST', body=None, headers={'content-type':'text/plain'}):
        """Send the actual request"""
        h = Http()
        h.add_credentials(self.AccountSid, self.AuthToken)
        resp, content =  h.request(url, method=method, body=body, headers=headers)

        print content

        if resp['status'] == '200':
            return loads(content)
        else:
            raise TwilioError(resp['status'], content)

    def sms(self, To, Body, From=None):
        """Sends a request to Twilio having it call a number; the provided URL will indicate how to handle the call"""
        url = _TWILIO_URL % (self.AccountSid, 'SMS/Messages')
        data = dict(From=self._get_from(From), To=To, Body=Body)
        return self.request(url, body=urlencode(data))

我在google上找不到任何关于故障排除的内容

Answer 1

Twilio在their API docs concerning POST requests中提到了这个要求：

但请务必设置HTTP   Content-Type标题为
  “应用程序/ x WWW的形式进行了urlencoded”   如果你是你的要求   写自己的客户。

Answer 2

事实证明，'content-type'必须设置为'application / x-www-form-urlencoded'。如果有人知道原因，请告诉我。

Python httplib2.Http不发送post参数
