正如DotNetNuke文档中所建议的那样,从UNC共享中运行IIS Web应用程序有什么不好?(What's so bad about running an IIS web application from an UNC share, as suggested in DotNetNuke docs?)

过去我曾教过,从UNC份额运行Web应用程序是不明智的。 我记得的原因是安全,权利和授权的麻烦和性能。 但是,在DotNetNuke文档中,它说

DotNetNuke最初支持的Web服务器场配置涉及两个或更多前端Web服务器(“网站负责人”),其IIS网站根目录映射到远程文件服务器上的公共UNC共享。 UNC共享包含应用程序源代码以及各个站点​​的任何静态内容。

不知何故,这听起来像一个穷人的配置,我觉得打开一个潜在的潘多拉盒子。 遵循DotNetNuke Corp的建议是否明智?


I've been taught in the past that it is unwise to run a web application from an UNC share. Reasons I remember are security, rights and authorization trouble and performance. However, in the DotNetNuke documentation it says:

The web farm configuration that DotNetNuke initially supports involves two or more front end web servers ("web-heads") whose IIS website root directories are mapped to a common UNC share on a remote file server. The UNC share contains the application source code as well as any static content for the individual sites.

Somehow this sounds to me like a poor-mans configuration and I feel like opening a potential Pandora's box. Is it wise to follow DotNetNuke Corp's suggestion here?

您发布的示例没有什么意义,并且它不允许任何合理的方式指定缺少的数据。 我在这里猜测,但你可能处理的唯一合理的事情似乎是这样的:

>>> lats = np.array([43.2, 43.2, 43.2, 45.5, 45.5, 45.5, 65.3, 65.3, 65.3])
>>> lons = np.array([5.5, 102.5, 116.2, 5.5, 102.5, 116.2, 5.5, 102.5, 116.2])
>>> vals = np.array([3, 4, 5, 6, 7, 7, 9, 1, 0])

如果vals[j]的值来自纬度纬度lats[j]和经度lons[j] ,但数据可能会混乱,如下所示:

>>> indices = np.arange(9)
>>> np.random.shuffle(indices)
>>> lats = lats[indices]
>>> lons = lons[indices]
>>> vals = vals[indices]
>>> lats
array([ 45.5,  43.2,  65.3,  45.5,  43.2,  65.3,  45.5,  65.3,  43.2])
>>> lons
array([   5.5,  116.2,  102.5,  116.2,    5.5,  116.2,  102.5,    5.5,  102.5])
>>> vals
array([6, 5, 1, 7, 3, 0, 7, 9, 4])

你可以按如下方式将它排列成一个数组:

>>> lat_vals, lat_idx = np.unique(lats, return_inverse=True)
>>> lon_vals, lon_idx = np.unique(lons, return_inverse=True)
>>> vals_array = np.empty(lat_vals.shape + lon_vals.shape)
>>> vals_array.fill(np.nan) # or whatever yor desired missing data flag is
>>> vals_array[lat_idx, lon_idx] = vals
>>> vals_array
array([[ 3.,  4.,  5.],
       [ 6.,  7.,  7.],
       [ 9.,  1.,  0.]])

The example you have posted makes very little sense, and it doesn't allow any reasonable way to specify missing data. I am guessing here, but the only reasonable thing you may be dealing with seems to be something like this :

>>> lats = np.array([43.2, 43.2, 43.2, 45.5, 45.5, 45.5, 65.3, 65.3, 65.3])
>>> lons = np.array([5.5, 102.5, 116.2, 5.5, 102.5, 116.2, 5.5, 102.5, 116.2])
>>> vals = np.array([3, 4, 5, 6, 7, 7, 9, 1, 0])

Where the value in vals[j] comes from latitude lats[j] and longitude lons[j], but the data may come scrambled, as in :

>>> indices = np.arange(9)
>>> np.random.shuffle(indices)
>>> lats = lats[indices]
>>> lons = lons[indices]
>>> vals = vals[indices]
>>> lats
array([ 45.5,  43.2,  65.3,  45.5,  43.2,  65.3,  45.5,  65.3,  43.2])
>>> lons
array([   5.5,  116.2,  102.5,  116.2,    5.5,  116.2,  102.5,    5.5,  102.5])
>>> vals
array([6, 5, 1, 7, 3, 0, 7, 9, 4])

You can get this arranged into an array as follows:

>>> lat_vals, lat_idx = np.unique(lats, return_inverse=True)
>>> lon_vals, lon_idx = np.unique(lons, return_inverse=True)
>>> vals_array = np.empty(lat_vals.shape + lon_vals.shape)
>>> vals_array.fill(np.nan) # or whatever yor desired missing data flag is
>>> vals_array[lat_idx, lon_idx] = vals
>>> vals_array
array([[ 3.,  4.,  5.],
       [ 6.,  7.,  7.],
       [ 9.,  1.,  0.]])
