错误：[Errno 32] 破损的管道django

Question

有时当我查看我的终端时，会看到以下错误，请问有人能告诉我它为什么会显示，并且如何避免它出现？

Exception happened during processing of request from ('127.0.0.1', 39444)

Answer 1

你得到该错误是由于以下两个原因之一。你也可能由于其他原因看到相同的问题。

1-在您的url末尾缺少“/”，您可以通过在所请求的URL末尾添加“/”来修复它。

2-您发出了一些请求，然后很快停止了。 例如调用一个url，然后取消调用并调用另一个url。检查您在哪里发起调用（JavaScript还是后端），并确保您调用url时没有将其取消。

Answer 2

这可能是因为您使用了两种方法将数据插入数据库，导致网站变慢。

def add_subscriber(request, email=None):
    if request.method == 'POST':
        email = request.POST['email_field']
        e = Subscriber.objects.create(email=email).save()  <==== 
        return HttpResponseRedirect('/')
    else:
        return HttpResponseRedirect('/')

例如，在上面的函数中，箭头指向错误之处。实现上述功能的正确方法是：

def add_subscriber(request, email=None):
    if request.method == 'POST':
        email = request.POST['email_field']
        e = Subscriber.objects.create(email=email)
        return HttpResponseRedirect('/')
    else:
        return HttpResponseRedirect('/')
