Question

当我尝试使用POST方法使用表单时，我遇到了一个TypeError：无法将字节连接到str。这不仅发生在我使用表单时，而且当我输入管理面板的登录名/密码时。

Environment:

Request Method: POST
Request URL: http://photofresh.site/blog/post_new/

Django Version: 1.8
Python Version: 3.5.0
Installed Applications:

    ['django.contrib.admin',
     'django.contrib.auth',
     'django.contrib.contenttypes',
     'django.contrib.sessions',
     'django.contrib.messages',
     'django.contrib.staticfiles',
     'bootstrap3',
     'blog']

Installed Middleware:

    ['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']


Traceback:

      125. response = middleware_method(request, callback, callback_args, callback_kwargs)

      233. self._body = self.read()

      292. return self._stream.read(*args, **kwargs)

File "/usr/local/lib/python3.5/site-packages/django/core/handlers/wsgi.py" in read

      51. result = self.buffer + self._read_limited()

Exception Type: TypeError at /blog/post_new/
Exception Value: can't concat bytes to str

这是我的HTML表单。我知道使用Django Forms会更好，但是当我在计算机上使用runserver命令时，这个特殊的例子运行得非常好。

<form action="{% url 'blog:post_new' %}" method="post">
{% csrf_token %}
Name:<br>
<input type="text" name="name"><br>
Text:<br>
<input type="text" name="text">
<input type="submit" value="Submit">
</form>

view.py：

def post_new(request):
posts = Post.objects.all().order_by('-date')
_name = request.POST['name']
_text = request.POST['text']
_date = timezone.now()
p = Post(name=_name, text=_text, date=_date)
p.save()
return render(request, 'blog/base.html', {'posts': posts})

Post方法在Django 1.8，Python3 TypeError中不起作用：无法将字节连接到str
