代碼：

from flask import Flask, request
import json
import sys
defaultencoding = 'utf-8'
import logging

def tt(name, age):
? ? result_str = "%s今年%s歲" % (name, age)
? ? return result_str

app = Flask(__name__)

@app.route("/test_1.0", methods=["GET"])
def check():
? ? return_dict = {'return_code': '200', 'return_info': '處理成功', 'result': False}
? ? if request.args is None:
? ? ? ? return_dict['return_code'] = '5004'
? ? ? ? return_dict['return_info'] = '請求參數為空'
? ? ? ? quit()
? ? ? ? return json.dumps(return_dict, ensure_ascii=False)
? ? get_data = request.args.to_dict()
? ? name = get_data.get('name')
? ? age = get_data.get('age')
? ? return_dict['result'] = tt(name, age)

? ? return json.dumps(return_dict, ensure_ascii=False)

if __name__ == "__main__":
? ? app.run("0.0.0.0", port=5000, debug=True)

錯誤：

UnsupportedOperation: not writable

針對上述錯誤： 定位到D:\Soft-win10\Microsoft Visual Studio\Shared\Anaconda3_64\lib\site-packages\click\utils.py的函數echo，將參數file=None，改成file=sys.stdout

再次運行出錯：

針對上述錯誤： 定位到D:\Soft-win10\Microsoft Visual Studio\Shared\Anaconda3_64\lib\site-packages\click\termui.py中的函數secho，將參數file=None，改成file=sys.stdout

修改后，運行成功！！！
