將環境建置完成後，再來要試著來處理 GET/POST 連線，
其實沒有真正要做什麼東西，只是想要玩玩看是否真的能成功來 post 資料並且顯示在 web 上，
目標如下：
POST
- 收到 POST 連線後，抓到 post data
- 將 data 內容 output 成一個文字檔
- 回傳收到的 data, time, from ip
GET
- 讀取文字檔內容
- 在 web 上顯示最新的 data 資訊
實作
import flask
import functools
import os
import datetime
import time
app = flask.Flask(__name__)
@app.route('/wtf', methods=['POST', 'GET'])
def wtf():
fileName = 'lastReceive.txt'
if flask.request.method == 'GET':
getFile = open(fileName, 'r')
text = getFile.read()
getFile.close()
spilt = text.split('$')
return '<br>' + 'Last Received POST Data is : "' + spilt[0] + '"' + '<br>' + 'From : ' + spilt[1]+ '<br>' + 'Date : ' + spilt[2]
elif flask.request.method == 'POST':
receivePost = flask.request.stream.read()
ip = flask.request.remote_addr
now = datetime.datetime.fromtimestamp(time.time()).strftime('%Y-%m-%d %H:%M:%S')
write = receivePost + '$' + ip + '$' + now
if not os.path.isfile(fileName):
tempFile = open(fileName, 'a')
else:
tempFile = open(fileName, 'w')
tempFile.write(write)
tempFile.close()
return '<br>' + 'Receive POST Data is : "' + receivePost + '"' + '<br>' + 'From : ' + ip + '<br>' + 'Date : ' + now
def main():
port = int(os.environ.get('PORT', 5000))
app.run(host='0.0.0.0', port=port)
if __name__ == '__main__': main()
