【问题描述】：
我知道 Broken pipe 是由于请求冲突造成的，因此 POST 没有时间处理。
我在这里发送这两个请求：
- 阿贾克斯邮报
- 重定向到 /message.html
所以 event.preventDefault() 可能会解决这个问题。但是，当我添加 preventDefault() 选项时，我根本没有收到 POST 请求。 添加超时将是一个非常糟糕的解决方案，因为它会在每次请求时停止。
我得到的错误是：
[13/Apr/2016 10:36:38]"POST /secreturl HTTP/1.1" 500 12202
- Broken pipe from ('127.0.0.1', 51133)

我还要补充一件事，我也无法发送 csrf_token，因为我要去 JSON.stringify(data) django 无法从中提取 csrf_token，而且我'没有使用任何形式，所以无法使用：
<form></form> {% csrf_token %}
服务器端：
//views.py
def home(request):
print "Request has been received"
print request
context = {
'MEDIA_ROOT' : "//home//mayur//Documents//Gigit//Gigit//Gigit//static//images//",
'MEDIA_URL' : 'http://localhost:8000/static/',
}
return render(request, "index2.html", context)
def test(request):
print "POST works"
#return render(request,"", {})
def message(request):
print " message request received"
return render(request, "message.html", {})
def insertQuery(request):
print "Insert query received"
# resp = json.loads(request)
# print resp
print request
//models.py
class visitors(models.Model):
id = models.AutoField(primary_key=True)
email = models.CharField(max_length = 50)

【问题讨论】：
-
@Koterpillar 我认为服务器代码不会有帮助
-
管道中断是指请求被中间的客户端取消。当浏览器导航到 /messages 时，它会中止您的 ajax 调用。您要么需要在执行重定向之前等待 ajax 调用完成，要么将您的 ajax 参数传递给消息 url 并在消息视图中处理它们（可以在前面添加另一个中间页面来检查条件然后重定向到消息） .
-
@serg 即使它导致错误，我的代码也可以正常工作。我可以安全地忽略它还是会成为一个问题？
