Question

对于第三方API，我使用的是oauth2模块，我有以下代码：当我使用python run.py但在使用IOError配置时拒绝apache +mod_wsgi权限时，哪个效果很好。

这是错误：

ERROR: Traceback (most recent call last):

from flask import Flask, jsonify
from api_manager import APIManager
from settings import *
app = Flask(__name__)

@app.route("/")

    try:
        apiobj = APIManager()
        response = apiobj.get_api_content(CONSUMER_KEY, CONSUMER_SECRET, ACCESS_TOKEN, ACCESS_SECRET)
    except Exception, e:
        logerror("ERROR:", e)
        return jsonify({})
    return jsonify(response)

Apache WSGI配置：

<VirtualHost _default_:443>
  ...
   # Default other config goes here...
  WSGIScriptAlias / /home/trex/workspace/scripts/appwsgi.py
  WSGIScriptReloading On
  <Directory "/home/trex/workspace/scripts">
    <Files "appwsgi.py">
       Require all granted
    </Files>
  </Directory>
</VirtualHost>

如果有任何其他问题我可以告诉您详情。

我的virtualenv的权限存在问题。以下文件有权限问题。

myenv/lib/python2.7/site-packages/httplib2-0.9.2-py2.7.egg/httplib2/cacerts.txt

这个简单的修复解决了我的问题：

chmod  -R 755  /home/trex/workspace/myenv

与mod_wsgi + Apache一起使用时，oauth2.request的IOError
