We have a django app and I need to add some functionality with NodeJS. I've been following this example: http://www.maxburstein.com/blog/realtime-django-using-nodejs-and-socketio/ using socket.io and it works perfect on localhost. Now, the problem comes when moving the application to apache server. I need to send a POST request to django and all I get is a timeout response. Our django ap
我们有一个django应用程序，我需要为NodeJS添加一些功能。 我一直在关注这个例子：http://www.maxburstein.com/blog/realtime-django-using-nodejs-and-socketio/使用socket.io它在本地主机上工作得很好。 现在，将应用程序移动到apache服务器时出现问题。 我需要发送POST请求到Django，我得到的只是一个超时响应。 我们在apache上的django应用程序正在侦听端口80，并且节点正在侦听端口4000. http请求的配置如下所示： var
I've trying to get a loop in python to run as fast as possible. So I've dived into NumPy and Cython. Here's the original Python code: def calculate_bsf_u_loop(uvel,dy,dz): """ Calculate barotropic stream function from zonal velocity uvel (t,z,y,x) dy (y,x) dz (t,z,y,x) bsf (t,y,x) """ nt = uvel.shape[0] nz = uvel.shape[1] ny = uvel.shape[2]
我试图让python中的循环尽可能快地运行。 所以我已经潜入NumPy和Cython。 这是原始的Python代码： def calculate_bsf_u_loop(uvel,dy,dz): """ Calculate barotropic stream function from zonal velocity uvel (t,z,y,x) dy (y,x) dz (t,z,y,x) bsf (t,y,x) """ nt = uvel.shape[0] nz = uvel.shape[1] ny = uvel.shape[2] nx = uvel.shape[3] bsf = np.zeros((nt,ny,nx))
I want to get the total number of records in an aggregate cursor in pymongo version 3.0+. Is there any way to get total count without iterating over the cursor? cursor = db.collection.aggregate([{"$match": options},{"$group": {"_id": groupby,"count": {"$sum":1}}} ]) cursorlist = [c for c in cursor] print len(cursorlist) Is there any way to skip the above iteration? 您可以添加另一个组管道，您
我想在pymongo版本3.0+中获取聚合游标中的记录总数。 有什么办法可以在没有迭代游标的情况下获得总数？ cursor = db.collection.aggregate([{"$match": options},{"$group": {"_id": groupby,"count": {"$sum":1}}} ]) cursorlist = [c for c in cursor] print len(cursorlist) 有没有办法跳过上面的迭代？ 您可以添加另一个组管道，您可以在其中指定_id值None来计算所有输入文档的累计值，这是您可以从中获取总计数以及原始
I am trying to write python script to find out if a disk device exists in /dev, but it always yield False. Any other way to do this? I tried >>> import os.path >>> os.path.isfile("/dev/bsd0") False >>> os.path.exists("/dev/bsd0") False $ ll /dev ... brw-rw---- 1 root disk 252, 0 Nov 12 21:28 bsd0 ... This was not rigorously tested, but seems to work: impor
我正在尝试编写python脚本以查明/ dev中是否存在磁盘设备，但它总是会产生False。 任何其他方式来做到这一点？ 我试过了 >>> import os.path >>> os.path.isfile("/dev/bsd0") False >>> os.path.exists("/dev/bsd0") False $ ll /dev ... brw-rw---- 1 root disk 252, 0 Nov 12 21:28 bsd0 ... 这没有经过严格的测试，但似乎工作： import stat import os.stat def disk_exists(path)
I am looking to scrape data from this site's mma data and parsing a few highcharts tables. I am clicking a link with selenium and then switching to the chart. I go to this site and click on +420 in the Artem Lobov row for the Pinnacle column. This creates a pop out chart. Then I switch to the active element. I would like to capture the graph drawn by highcharts in response to the click.
我正在寻找从本网站的mma数据中提取数据并解析一些highcharts表格。 我点击了一个有硒的链接，然后切换到图表。 我去了这个网站，点击Artem Lobov排中的+420获得Pinnacle专栏。 这会创建一个弹出式图表。 然后我切换到活动元素。 我想要捕获高点图绘制的图表以响应点击。 我以如下方式使用硒： actions = ActionChains(driver) actions.move_to_element(driver.find_element_by_id(pin_id)) actions.click() actions.perf
