POST方法向网站发送数据

server.py

import flask
app = flask.Flask(__name__)

@app.route('/', methods=['GET','POST'])
def index():
    try:
        province = flask.request.form.get('province')
        city = flask.request.form.get('city')
        note = flask.request.form.get('note')
        print(province, city, note)
        return province + "\n" + city + "\b" + note
    except Exception as e:
        print(e)

debug = True
if __name__ == '__main__':
    app.run()

client.py

import urllib.request
import urllib.parse

url = "http://127.0.0.1:5000"

province = "山东"
city = "青岛"
note = "青岛地处山东半岛东南部沿海，胶东半岛东部，濒临黄海，隔海与朝鲜半岛相望，地处中日韩自贸区的前沿地带； 东北与烟台毗邻，西与潍坊相连，西南与日照接壤； 青岛因地理位置优越继而1891年清政府驻兵建置，1897年德国租借建设港口和铁路，青岛因“一港一路”而兴，拥有国际性海港和区域性枢纽航空港，是实施海上丝绸之路、履行国家一带一路战略重要的枢纽型城市。"

# urllib.parse模块中的一个方法，用于将字符串进行URL编码,URL编码是将URL中的非ASCII字符和一些特殊字符转换成特定的格式
province = urllib.parse.quote(province)
city = urllib.parse.quote(city)
province = urllib.parse.quote(province)

pc = "province=" + province + "&city=" + city + "¬e=" + note

response = urllib.request.urlopen(url, data = pc.encode())
data = response.read()
html = data.decode("utf-8")
print(html)
