Http是常用的通讯协议，使用的对应Python库名为requests和Flask；
from flask import Flask,request,make_response
app = Flask(__name__)
@app.route('/', methods=['GET', 'PUT', 'POST'])
def index():
if request.method == 'GET':
if request.args['status'] == 'ok':
data = {"result": "success","msg": "welcome to use get."}
return data
elif request.method == 'PUT':
if request.form['User'] == 'FK2000':
if request.form['Password'] == '12345':
print(request.form)
data = {"result": "success","cookies": "9f6e7t3j5l1k2s0x"}
return data
elif request.method == 'POST':
if request.form['action'] == 'upload_log':
if request.cookies['cookies'] == "9f6e7t3j5l1k2s0x":
print(request.headers['mp3'])
data = {"result": "success","msg": "upload log ok."}
return data
elif request.form['action'] == 'upload':
if request.cookies['cookies'] == "9f6e7t3j5l1k2s0x":
print(request.files)
request.files['file'].save('./1024.mp3')
file_bytes = request.files['file'].stream.read()
data = {"result": "success","msg": "upload ok."}
response = make_response(data)
header_add = {'upload':'ok'}
response.headers = header_add
return response
if __name__ == '__main__':
app.run(host="127.0.0.1", port=5000, debug=True)上段为Flask服务器部分，下段为requests客户端部分；
