HTTPResponse对象-JSON对象必须为str，而不是'bytes' [英] HTTPResponse object -- JSON object must be str, not 'bytes'

问题描述

我一直在尝试更新一个名为 libpynexmo 的小型Python库，以便与Python 3配合使用. /p>

我一直在使用此功能:

def send_request_json(self, request):
    url = request
    req =  urllib.request.Request(url=url)
    req.add_header('Accept', 'application/json')
    try:
        return json.load(urllib.request.urlopen(req))
    except ValueError:
        return False

当涉及到此内容时，json会回应:

TypeError: the JSON object must be str, not 'bytes'

我在一些地方读到，对于json.load，您应该传递附加了.read()的对象(在这种情况下为HTTPResponse对象)，但不适用于HTTPResponse对象.

我不知道下一步该怎么做，但是由于我的整个1500行脚本是新转换为Python 3的，所以我不想回到2.7.

解决方案

我最近编写了一个小函数来发送Nexmo消息.除非您需要libpynexmo代码的全部功能，否则这应该为您完成工作.而且，如果您想继续检修libpynexmo，只需复制此代码即可.关键是utf8编码.

如果您想随邮件一起发送其他任何字段，请参见nexmo出站邮件 Nexmo 出站(JSON):

def nexmo_sendsms(api_key, api_secret, sender, receiver, body):
    """
    Sends a message using Nexmo.

    :param api_key: Nexmo provided api key
    :param api_secret: Nexmo provided secrety key
    :param sender: The number used to send the message
    :param receiver: The number the message is addressed to
    :param body: The message body
    :return: Returns the msgid received back from Nexmo after message has been sent.
    """


    msg = {
        'api_key': api_key,
        'api_secret': api_secret,
        'from': sender,
        'to': receiver,
        'text': body
    }
    nexmo_url = 'https://rest.nexmo.com/sms/json'
    data = urllib.parse.urlencode(msg)
    binary_data = data.encode('utf8')
    req = urllib.request.Request(nexmo_url, binary_data)
    response = urllib.request.urlopen(req)
    result = json.loads(response.readall().decode('utf-8'))
    return result['messages'][0]['message-id']

I've been trying to update a small Python library called libpynexmo to work with Python 3.

I've been stuck on this function:

def send_request_json(self, request):
    url = request
    req =  urllib.request.Request(url=url)
    req.add_header('Accept', 'application/json')
    try:
        return json.load(urllib.request.urlopen(req))
    except ValueError:
        return False

When it gets to this, json responds with:

TypeError: the JSON object must be str, not 'bytes'

I read in a few places that for json.load you should pass objects (In this case an HTTPResponse object) with a .read() attached, but it doesn't work on HTTPResponse objects.

I'm at a loss as to where to go with this next, but being that my entire 1500 line script is freshly converted to Python 3, I don't feel like going back to 2.7.

解决方案

I recently wrote a small function to send Nexmo messages. Unless you need the full functionality of the libpynexmo code, this should do the job for you. And if you want to continue overhauling libpynexmo, just copy this code. The key is utf8 encoding.

If you want to send any other fields with your message, the full documentation for what you can include with a nexmo outbound message is here

Python 3.4 tested Nexmo outbound (JSON):

def nexmo_sendsms(api_key, api_secret, sender, receiver, body):
    """
    Sends a message using Nexmo.

    :param api_key: Nexmo provided api key
    :param api_secret: Nexmo provided secrety key
    :param sender: The number used to send the message
    :param receiver: The number the message is addressed to
    :param body: The message body
    :return: Returns the msgid received back from Nexmo after message has been sent.
    """


    msg = {
        'api_key': api_key,
        'api_secret': api_secret,
        'from': sender,
        'to': receiver,
        'text': body
    }
    nexmo_url = 'https://rest.nexmo.com/sms/json'
    data = urllib.parse.urlencode(msg)
    binary_data = data.encode('utf8')
    req = urllib.request.Request(nexmo_url, binary_data)
    response = urllib.request.urlopen(req)
    result = json.loads(response.readall().decode('utf-8'))
    return result['messages'][0]['message-id']
