Question

我一直在努力尝试编辑最初用于天气API的webhook，以便与邮政编码/邮政编码API一起使用。原始文件位于：https://github.com/dialogflow/fulfillment-webhook-weather-python/blob/master/app.py 我无法理解我的不同之处，我认为当我用引号替换urlencode时我已经解决了它，但唉，这还不够。问题不太可能与在postcodeValue（）中收集邮政编码的源json请求有关。当您将其输入浏览器并且呈现非常简单时，api url会正确显示。 https://api.getaddress.io/find/SW11%201th?api-key=I98umgPiu02GEMmHdmfg3w12959 它的格式是否正确？也许我需要将它转换为更多JSON然后它已经是。这个问题基本上是一天的脑溢流，我希望有人可以救我。

以下是您的代码的清洁版本：

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，您会看到回复。
