我在使用python日志记录的HTTPHandler将消息推送到客户django应用程序时遇到了一些问题。我有一个单独的守护进程，它是我的基础结构的一部分，我希望它将日志推送到django所以我有点在一个地方得到所有。
我正在使用： Ubuntu 10.04 Django 1.2.4 PostgreSQL 8.4 python 2.6.5
这是模型
from django.db import models
# Create your models here.
class application(models.Model):
app_name = models.CharField(max_length= 20)
description = models.CharField(max_length = 500, null=True)
date = models.DateField()
def __unicode__(self):
return ("%s logs - %s") % (self.app_name, self.date.strftime("%d-%m-%Y"))
class log_entry(models.Model):
application = models.ForeignKey(application)
thread_name = models.CharField(max_length = 200,null = True)
name = models.CharField(max_length = 200,null = True)
thread = models.CharField(max_length=50, null = True)
created = models.FloatField(null = True)
process = models.IntegerField(null = True)
args = models.CharField(max_length = 200,null = True)
module = models.CharField(max_length = 256,null = True)
filename = models.CharField(max_length = 256,null = True)
levelno = models.IntegerField(null = True)
msg = models.CharField(max_length = 4096,null = True)
pathname = models.CharField(max_length = 1024,null = True)
lineno = models.IntegerField(null = True)
exc_text = models.CharField(max_length = 200, null = True)
exc_info = models.CharField(max_length = 200, null = True)
func_name = models.CharField(max_length = 200, null = True)
relative_created = models.FloatField(null = True)
levelname = models.CharField(max_length=10,null = True)
msecs = models.FloatField(null = True)
def __unicode__(self):
return self.levelname + " - " + self.msg
这是视图
# Create your views here.
from django.shortcuts import render_to_response, get_list_or_404, get_object_or_404
from django.http import HttpResponse, HttpResponseRedirect
from django.views.decorators.csrf import csrf_protect, csrf_exempt
from inthebackgroundSite.log.models import log_entry, application
import datetime
@csrf_exempt
def log(request):
print request.POST
for element in request.POST:
print ('%s : %s') % (element, request.POST[element])
data = request.POST
today = datetime.date.today()
print today
app = application.objects.filter(app_name__iexact = request.POST["name"], date__iexact=today)
if not app:
print "didnt find a matching application. adding one now.."
print data["name"]
print today
app = application.objects.create(app_name = data["name"],
description = None,
date = today)
app.save()
if not app:
print "after save you cant get at it!"
newApplication = app
print app
print "found application"
newEntry = log_entry.objects.create(application = app,
thread_name = data["threadName"] ,
name = data["name"],
thread = data["thread"],
created = data["created"],
process = data["process"],
args = "'" + data["args"] + "'",
module = data["module"],
filename = data["filename"],
levelno = data["levelno"],
msg = data["msg"],
pathname = data["pathname"],
lineno = data["lineno"],
exc_text = data["exc_text"],
exc_info = data["exc_info"],
func_name = data["funcName"],
relative_created = data["relativeCreated"],
levelname = data["levelname"],
msecs = data["msecs"],
)
print newEntry
#newEntry.save()
return HttpResponse("OK")
这是在python代码中调用发送消息。
import os
import logging
import logging.handlers
import time
if __name__ == '__main__':
formatter = logging.Formatter("%(name)s %(levelno)s %(levelname)s %(pathname)s %(filename)s%(module)s %(funcName)s %(lineno)d %(created)f %(asctime)s %(msecs)d %(thread)d %(threadName)s %(process)d %(processName)s %(message)s ")
log = logging.getLogger("ShoutGen")
#logLevel = "debug"
#log.setLevel(logLevel)
http = logging.handlers.HTTPHandler("192.168.0.5:9000", "/log/","POST")
http.setFormatter(formatter)
log.addHandler(http)
log.critical("Finished MountGen init")
time.sleep(20)
http.close()
现在我第一次发送带有空表的消息。它工作正常，创建一个新的应用程序行并创建一个新的日志消息。但是我第二次打电话给我，

并且没有额外的行插入到log_log_entry表中。所以我真的不知道为什么会发生这种情况。
我环顾四周，显然Broken管道追溯不是问题，只是浏览器所做的事情。但我没有使用浏览器，所以我不确定问题是什么。
答案 0 :(得分：0)
可能是异常导致事务回滚并撤消更改。你在使用TransactionMiddleware吗？您可以在视图上尝试transaction.autocommit装饰器。
如果“破管”错误不断发生，那么值得找出原因。 HTTPHandler执行正常的POST并在其emit()调用中等待响应（“视图”中的“确定”），并且在此之前不应断开连接。
您可以尝试使用httplib和urllib作为HTTPHandler本身从测试脚本向您的视图发送等效帖子。基本上，只需对POST数据进行urlencode dict，就像它是LogRecord's dict一样。
