Question

我的Django应用出现500错误，打开调试模式时出现400错误代码。我使用Python 3.5

关于这个：

token = FacebookToken.objects.get(id=1).token

url = "https://graph.facebook.com/v3.2/lamontagnesolitaire?access_token="+str(token)+"&fields=posts{id}"

fb_query = urlopen(url).read().decode('utf-8')

查询工作正常，因为当我将“令牌”作为纯字符串放置时，我没有任何错误，并且可以正确读取URL。

我已经尝试过此方法或某些变体：

url = "https://graph.facebook.com/v3.2/lamontagnesolitaire?access_token=%s&fields=posts{id}" %token

fb_query = urlopen(url).read().decode('utf-8')

我仍然收到400错误消息。

“ token”变量返回了一个好变量：

token = 'EAAIgMT9IUZBIBAI7hKtwxZCIydOeAuZCr4ddw4aGRIZCvDJHQtt2yuGYRtZBAZBGK9LsMcZAGG3VFLRQVOQU2mGkL[....]'

我的模特：

class FacebookToken(models.Model):
    token = models.CharField(max_length=300, null=False, verbose_name="Token")
