使用apache2和google-cloud-storage时出现内部服务器错误

Question

因此，我设法为谷歌获取了所有挂钩的up.The路径，并且设置apache2似乎运行得很好；我收到一个内部错误;/在server.In中，函数.However

storage_client= storage.Client()会导致错误

在函数测试中

storage_client= storage.Client()成功了，python能够找到secret.json，这对我来说很奇怪。

#__init__.py code
from flask import Flask
from google.cloud import storage

app = Flask(__name__)

@app.route("/")
def hello():
    #Does not work here
    storage_client= storage.Client()
    return "error"

#Works without @app.route("")
def test():    
    storage_client= storage.Client()
    # successfuly connects and prints
    print(storage_client) 

if __name__ == "__main__":
    app.run()

#wsgi code
#!/usr/bin/python
#!/usr/secret.json
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/html/FlaskApp/")
from google.cloud import storage
from FlaskApp import app as application

application.secret_key = 'Add your secret key'

这是日志，似乎在flaskapp.wsgi中有一个错误，但我不是很确定...

mod_wsgi (pid=23303): Target WSGI script '/var/www/html/FlaskApp/flaskapp.wsgi' cannot be loaded as Python module.

Answer 1

您需要提供计划使用的服务帐户的凭据。正如您在错误中看到的，您可以为此设置environment variable GOOGLE_APPLICATION_CREDENTIALS。

要实现这一点，请完成以下步骤：

• 为您计划使用的服务帐户下载JSON格式的。Windows
• (在Linux或MacOS上)运行：export GOOGLE_APPLICATION_CREDENTIALS="[PATH-TO-THE-KEY]"
• (on

)：$env:GOOGLE_APPLICATION_CREDENTIALS="[PATH-TO-THE-KEY]"

Alternatively，您可以在代码中通过pass the path连接到服务帐户密钥：

storage_client = storage.Client.from_service_account_json(
        'service_account_key.json')
