我的 python webhook 没有给我结果

Question

我一直在尝试编辑一个最初用于天气 API 的 webhook，以便与邮政编码/邮政编码 API 一起使用。原文件在这里：https://github.com/dialogflow/fulfillment-webhook-weather-python/blob/master/app.py 我不明白我的不同之处，当我用引号替换 urlencode 时，我以为我已经解决了它，但是唉，这还不够。 该问题不太可能与在 postcodeValue() 中收集邮政编码的源 json 请求有关。当您在浏览器中输入 api url 时，它会显示正确，并且显示得非常简单。 https://api.getaddress.io/find/SW11%201th?api-key=I98umgPiu02GEMmHdmfg3w12959 格式是否正确？也许我需要将它转换成更多的 JSON，然后它已经是。这个问题本质上是我希望有人可以拯救我的一天结束的大脑转储。

这里是你的代码更简洁的版本：

from urllib.request import urlopen
import os
from flask import Flask

app = Flask(__name__)

@app.route('/webhook', methods=['GET'])
def webhook():
    res = processRequest()
    return res


def processRequest():
try:
    result = urlopen("https://api.getaddress.io/find/SW11%201th?api-key=I98umgPiu02GEMmHdmfg3w12959").read()
    return result
except:
    return "Error fetching data"

if __name__ == '__main__':
    port = int(os.getenv('PORT', 5000))

    print("Starting app on port %d" % port)

    app.run(debug=False, port=port, host='0.0.0.0')

打开浏览器并转到http://localhost:5000/webhook，您应该会看到回复。
