url_for with _external = True在heroku上不附加URL上的服务器名称 [英] url_for with _external=True on heroku doesn't append the server name on the URL

问题描述

  content = Content（text / html，verification_email.format（user [first_name]，
 url_for（register.display_register_form，
 token = token.decode utf-8），external = True）））
  

我的电子邮件是：

 的http：/// register_account / DnsJpXw_QIcPYeDHEg_fipB2kRiJBUj2RI6I9cI4Yl4w6K9ohbZRMVqBInuV0aOsBT4Zqt69X8MfhNfnys4s-DAQmgu1OPBwmSQnzAELvdcCyiZtkJGSY8_dQ799FOewtBDkvqR1D8XHmvVxgaVqbwSjdEBnvFsBBHMQCic％3D /验证外部=真
  

我遇到以下问题：

• 它不是https，应该是因为它是在heroku上的主机


• 服务器名称没有ar只在URL中 /// 如果服务器名称为空

我应该怎么做才能得到正确的URL https：// my-server-name / register_account ... ？

编辑

我尝试在config.py文件中设置以下变量：

SERVER_NAME = http://my-server-58140.herokuapp.com
$ b

它在我的路径中产生了错误，我无法访问任何URL，例如下面的一个可以访问，但是当定义我的它不再是：

$ p $ http：// my-server-58140 .herokuapp.com / home


编辑



我的应用程序配置为：



  SERVER_NAME = os.environ.get（'SERVER_NAME'） 
 DEBUG = True 
 BASE_DIR = os.path.abspath（os.path.dirname（__ file __））
  

其中environnement变量设置为 0.0.0.0:5000 在我的生产服务器上 my-server-58140.herokuapp.com






• > SERVER_NAME 添加到您网站的名称中，
  
• 和 PREFERRED_URL_SCHEME code> https 。

请参阅 url_for（） 和如何配置Flask应用程序。

编辑：此外， url_for 中的参数应该是 _external 而不是外部。

I have deploy an application on Heroku but the problem is when my application send email it doesn't append the name of my server in the URL:

content = Content("text/html", verification_email.format(user["first_name"],
                                                             url_for("register.display_register_form",
                                                                     token=token.decode("utf-8"), external=True)))

But the link I'm receiving in my email is:

http:///register_account/DnsJpXw_QIcPYeDHEg_fipB2kRiJBUj2RI6I9cI4Yl4w6K9ohbZRMVqBInuV0aOsBT4Zqt69X8MfhNfnys4s-DAQmgu1OPBwmSQnzAELvdcCyiZtkJGSY8_dQ799FOewtBDkvqR1D8XHmvVxgaVqbwSjdEBnvFsBBHMQCic%3D/verify?external=True

I have problems with this URL:

• It is not https and it should be since it's host on heroku
• The server name doesn't appear in the URL only /// like if the server name was blank

What should I do to have the correct URL https://my-server-name/register_account...?

EDIT

I tried to set in my config.py file with the following variable to:

SERVER_NAME = "http://my-server-58140.herokuapp.com"

It generated errors in my path and I couldn't access any URL for example, the following one could be access before but when defining my SERVER_NAME it didn't anymore:

http://my-server-58140.herokuapp.com/home

EDIT

My flask application is configured:

SERVER_NAME = os.environ.get('SERVER_NAME')
DEBUG = True
BASE_DIR = os.path.abspath(os.path.dirname(__file__))

Where the environnement variable is set to 0.0.0.0:5000 on my localhost and: my-server-58140.herokuapp.com on my production server

解决方案

To generate the correct URL, these two Flask configuration values need to be set:

• SERVER_NAME to the name of your website,
• and PREFERRED_URL_SCHEME to https.

See the documentation for url_for() and how to configure a Flask application.

EDIT: Additionally, the parameter in url_for should be _external and not external.
