为什么在向 Giphy API 发出请求时收到 HTTP 错误 403?

Why do I get a HTTP Error 403 when making a request to the Giphy API?

我正在使用 urllib2 向 Giphy API 发出请求,并且我正在使用 public API 密钥。完全相同的代码在 Google App Engine 上运行良好,但是当我尝试使用 Pythonanywhere 执行它时,我得到 "HTTPError: HTTP Error 403: Forbidden"。我已经尝试添加一些 headers.

WEBHOOK_URL = 'https://url/webhook'
GIPHY_API_KEY = 'xxx'
BOT_TOKEN = 'xxx'
GIPHY_HOST = "http://api.giphy.com"

app = Flask(__name__)
bot = telegram.Bot(token=BOT_TOKEN)

@app.route('/webhook', methods=['POST'])
def webhook_handler():
    if request.method == "POST":
        update = telegram.Update.de_json(request.get_json(force=True))
        chat_id = update.message.chat_id
        text = update.message.text.encode('utf-8')

        if text:
            values = text.split(" ", 1)
            command = values[0].lower()

            if command == '/gif':
                if len(values) > 1:
                    endpoint = GIPHY_HOST + '/v1/gifs/random'
                    data = {
                        "api_key": GIPHY_API_KEY,
                        "tag": values[1],
                    }
                    endpoint = endpoint + '?' + urllib.urlencode(data)
                    req = urllib2.Request(endpoint)
                    resp= urllib2.urlopen(req)
                    image_url = json.loads(resp.read())["data"]["image_url"]
                    bot.sendMessage(chat_id=chat_id, text=image_url)
    return 'ok'

@app.route('/set_webhook', methods=['GET', 'POST'])
def set_webhook():
    bot.setWebhook(WEBHOOK_URL)
    return "webhook set"


@app.route('/')
def index():
    return '.'
