Question

我已经在多个地方搜索过，并尝试了多种方法来找到解决方案。但是没有任何帮助，请您帮我提供解决方案。在Google App Engine灵活的环境中托管python flask应用程序变得异常困难。 Python代码：“ getresource.py”

Here是Google部署Python Flask应用程序的链接

这是简单的代码：

from flask import Flask, jsonify
from pymysql import connections, ProgrammingError, DatabaseError, MySQLError, DataError
from os import environ

DB_HOST = environ.get("DB_HOST")
USER = environ.get("USER")
PWD = environ.get("PASSWORD")
DATABASE = environ.get("DATABASE")

app = Flask(__name__)

dbconn = connections.Connection(
                                host=DB_HOST,
                                port=3306,
                                user=USER,
                                password=PWD,
                                db=DATABASE
                                )

@app.route("/getResource/<id>", methods=['GET'])
def getresource(id):
    result = ()
    select_sql = "SELECT `id`, `firstName`, `middleName`, `lastName`, `listOfTechWorkedOn`, `certifications`, `projects`, `applicationWorkLoadTypes` FROM `resource` WHERE `id`=%s"
    cursor = dbconn.cursor()

    try:
        cursor.execute(select_sql, (id))
        result = cursor.fetchone()

        response = {}
        response['id'] = result[0]
        response['firstName'] = result[1]
        response['middleName'] = result[2]
        response['lastName'] = result[3]
        response['listOfTechWorkedOn'] = result[4]
        response['certifications'] = result[5]
        response['projects'] = result[6]
        response['applicationWorkLoadTypes'] = result[7]

        return jsonify(response)

    except ProgrammingError as p:
        return 
    except DatabaseError as d:
        return d
    except MySQLError as m:
        return m
    except DataError as de:
        return de

    dbconn.close()

if __name__ == '__main__':
    app.run(host='127.0.0.1',port=8080, debug=True)

这是app.yaml文件

runtime: python
env: flex
entrypoint: gunicorn -b :$PORT getresource:app
service: getresource

runtime_config:
  python_version: 3

manual_scaling:
  instances: 1

env_variables:
  DB_HOST: "1.2.3.4"
  USER: "root"
  PASSWORD: "abcdefg"
  DATABASE: "abcd"

requirements.txt文件

Flask==1.0.2
gunicorn==19.9.0
PyMySQL==0.9.2

我收到以下错误：“ gcloud应用程序部署”

错误：（gcloud.app.deploy）错误响应：[13]部署期间发生内部错误。

我已经尝试了多种方法，例如更改python代码，将Google谷歌云库放入requirements.txt，更改端口，服务名称等。但是似乎没有任何效果。

令人惊讶的是，我在堆栈驱动程序日志中也没有得到错误跟踪。而且Google似乎没有适当的答案（至少从我做过的所有谷歌搜索中）

gcloud版本

Google Cloud SDK 222.0.0
bq 2.0.36
core 2018.10.19
gsutil 4.34

编辑：

**感谢您的答复。我尝试了所有选项，但是在以下调试消息中得到了相同的错误。我不能用它做任何事

感谢您的回复。我尝试了所有建议的选项，但得到相同的错误。以下是调试日志，我无法使用它进行调试。
