Django Web 应用程序的 Heroku 错误请求服务器错误 500答案

【问题标题】：Heroku Bad Request Server Error 500 for Django Web appDjango Web 应用程序的 Heroku 错误请求服务器错误 500
【发布时间】：2018-10-24 20:09:06
【问题描述】：

我正在 Heroku 上部署一个生产环境中的 Django Web 应用程序。在检查heroku logs --tail 后，我收到服务器错误 (500)。

我不确定如何消除可能导致问题的用户警告。

注意，我从 prod.py 文件运行应用程序，并将我的 wsgi.py 设置为：

wsgi.py

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings.prod") # mysite.settings.prod when in prod

application = get_wsgi_application()

requirements.txt

dj-database-url==0.5.0
Django==2.1.2
django-heroku==0.3.1
# psycopg2==2.7.5
psycopg2-binary==2.7.5
pytz==2018.6
whitenoise==4.1
gunicorn==19.6.0

编辑

Heroku CLI 的日志文件

我已在本地开发人员和生产环境之间调整 Heroku PostgresQL 版本，并在本地开发人员中添加了 PostgresQL 以更加一致。当我测试 DEBUG=True 时，该站点工作。我在 Chrome 控制台日志中找不到任何错误

当前 Heroku 日志是：

标签： django heroku production-environment

【解决方案1】：

我找到了解决办法。

第 1 步

将此添加到生产设置文件（this code is from here 的来源）：

# Logging

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'console': {
            'class': 'logging.StreamHandler',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['console'],
             'level': os.getenv('DJANGO_LOG_LEVEL', 'DEBUG'),
        },
    },
}

第 2 步

确保您在本地运行 python manage.py collectstatic --noinput 并使用 git push heroku master 将您的代码推送到 Heroku 服务器。在 Heroku CLI 中也可以使用 heroku run python manage.py collectstatic --noinput

第三步

使用heroku logs --tail 捕获任何将通过调用步骤 1 中的代码突出显示的错误。就我而言，我有：

ValueError: Missing staticfiles manifest entry for 'assets/css/main.css'

此外，我使用以下代码消除了有关 psycog 二进制库的警告。

conn = psycopg2.connect(DATABASE_URL, sslmode='require')

和import psycopg2 在我的基本设置文件中。

最后，在其他地方有一些关于 Whitenoise 和静态文件目录的讨论。

我使用了以下设置：

import os
import dj_database_url
import django_heroku
import psycopg2
# import sys
# from secrets import *

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
PROJECT_ROOT = os.path.dirname(os.path.abspath(__file__))

# Quick-start development settings - unsuitable for production
# See https://docs.djangoproject.com/en/2.0/howto/deployment/checklist/

# Application definition

INSTALLED_APPS = [
    # Disable Django's own staticfiles handling in favour of WhiteNoise, for
    # greater consistency between gunicorn and `./manage.py runserver`. See:
    # http://whitenoise.evans.io/en/stable/django.html#using-whitenoise-in-development
    'whitenoise.runserver_nostatic',
    'django.contrib.staticfiles',
    'landing',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
]

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'whitenoise.middleware.WhiteNoiseMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

ROOT_URLCONF = 'mysite.urls'

WSGI_APPLICATION = 'mysite.wsgi.application'

AUTH_PASSWORD_VALIDATORS = [
    {
        'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',
    },
]

# Internationalization

LANGUAGE_CODE = 'en-us'
TIME_ZONE = 'UTC'
USE_I18N = True
USE_L10N = True
USE_TZ = True

ADMINS = (('Webmaster','peterdoh@gmail.com'))
MANAGERS = ADMINS

# Change 'default' database configuration with $DATABASE_URL.
# DATABASES['default'].update(dj_database_url.config(conn_max_age=500, ssl_require=True))

# Honor the 'X-Forwarded-Proto' header for request.is_secure()
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/2.0/howto/static-files/

STATIC_ROOT = os.path.join(PROJECT_ROOT, 'staticfiles')
STATIC_URL = '/static/'

# Extra places for collectstatic to find static files.
# STATICFILES_DIRS = [
#     os.path.join(PROJECT_ROOT, 'static'),
# ]

# Simplified static file serving.
# https://warehouse.python.org/project/whitenoise/
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

# Activate Django-Heroku.
django_heroku.settings(locals())

最后，在 wsgi.py 文件中，确保此配置：

import os

from django.core.wsgi import get_wsgi_application
# Whitenoise should not appear here: http://whitenoise.evans.io/en/stable/changelog.html#v4-0

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings.prod") # mysite.settings.prod when in prod

application = get_wsgi_application()

【讨论】：

我按照您在此处列出的步骤来隔离我得到的 Django/Heroku 应用程序上的间歇性 HTTP 500 错误。我能够隔离并解决问题。感谢您发布此内容。
嘿，我也有同样的问题，请问你最后是怎么解决的？
