nginx访问控制

阅读更多关于 nginx访问控制

Nginx的deny和allow https://coding.net/u/aminglinux/p/nginx/git/blob/master/access/deny_allow.md Nginx访问控制 —— deny_allow Nginx的deny和allow指令是由ngx_http_access_module模块提供，Nginx安装默认内置了该模块。除非在安装时有指定 --without-http_access_module。语法语法：allow/deny address | CIDR | unix: | all 它表示，允许/拒绝某个ip或者一个ip段访问.如果指定unix:,那将允许socket的访问。注意：unix在1.5.1中新加入的功能。在nginx中，allow和deny的规则是按顺序执行的。示例示例1： location / { allow 192.168.0.0/24; allow 127.0.0.1; deny all; } 说明：这段配置值允许192.168.0.0/24网段和127.0.0.1的请求，其他来源IP全部拒绝。示例2： location ~ "admin" { allow 110.21.33.121; deny all } 说明：访问的uri中包含admin的请求，只允许110.21.33.121这个IP的请求。

How would I use a pack uri resource with media player?

阅读更多关于 How would I use a pack uri resource with media player?

问题 I have some very simple code which just needs to play a sound with a specified volume, as follows : var mp = new MediaPlayer(); mp.Open(uri); mp.Volume = volume; mp.Play(); The problem arises because this is part of a Prism module. I don't know where the executing assembly is going to be so I can't use a relative Uri or siteoforigin and MediaPlayer doesn't understand the pack Uri syntax. I have a resource wav file at the root of my assembly called "notify.wav", but I have no way to pass it

Android 设置铃声

阅读更多关于 Android 设置铃声

在网上找了很多关于铃声设置的，不晓得怎么回事就是没测试通过，后来换了另外一种方式解决了。回过头来看了一下原理是一样的，于是就把两者合并到了一起。原理：首先根据传进来的绝对路径来查询传进来路径的歌曲是否存在，如果存在则得到id和uri，通过ContentUris.withAppendedId(uri,id),将uri和id拼接成一个新的Uri，然后将新的uri设置成想要的铃声即可。最主要的代码： RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE, newUri); 第一个参数表示上下文、第二个参数表示设置的铃声状态，第三个表示当前的歌曲uri。如果传进来的歌曲路径不存在，则直接调用系统的插入数据方法，得到一个返回的uri，这里得到的uri是不带id参数的，不晓得为什么，这样设置铃声是不成功的。我想到的笨方法是，在插入数据之后应该立即发送广播让系统扫描媒体数据，然后来查询得到新的uri，然后再来设置。不晓得哪位大牛有什么好的方法能够借鉴一下。 private void settingRingertone(String path2) { // TODO Auto-generated method stub ContentValues cv = new

Android Camera Video intent returns null URI

阅读更多关于 Android Camera Video intent returns null URI

问题 I recently got updated to Android 4.3 and the stock video camera started acting a little weird whenever I started it with an Intent from my app. At first it would just crash and say "Gallery stopped responding". After a little while, I was able to record a video, but clicking on done returned a null URI to my app, which made it crash! So I set out testing a 2.3.4 device with the same code. The video app returned a proper URI I could use on that device. The same code worked perfectly fine

Launching an application with an URI from winform

阅读更多关于 Launching an application with an URI from winform

问题 I have a URI that launches a default program and I'm trying to figure out how to launch it from a Windows Form application. All the results on Google are using the Windows Apps API to launch a URI, but I need to do it from a form. How can this be done? Here is the Apps version: System.Uri uri = new System.Uri("myprotocl://10.0.0.123"); var success = await Windows.System.Launcher.LaunchUriAsync(uri); 回答1: Assuming you have a 'handler' registered on your machine for 'myprotocl', you can launch

Ruby URI module produces illegal file-URI

阅读更多关于 Ruby URI module produces illegal file-URI

问题 This is a follow-up question to Converting file path to URI. Consider: require 'uri' uri = URI.join('file:///', '/home/user/dir1/dir2/dir3/name.ext') => #<URI::Generic:0x0000000263fcc0 URL:file:/home/user/dir1/dir2/dir3/name.ext> uri.to_s => "file:/home/user/dir1/dir2/dir3/name.ext" Isn't the result illegal? Shoudln't it be "file://home/..." , with a double slash? 回答1: No. file://home/... refers to a file on the host named 'home'. The full syntax is file:///home/... , with three slashes,

geographic location uri scheme

阅读更多关于 geographic location uri scheme

问题 I'd like to use a URI scheme to enable the users of one of my apps to share geographic locations. I don't want to invent my own URI scheme and "geo" seems the most appropriate but there are only two Internet Drafts on the subject (draft-mayrhofer-geo-uri-01, draft-mayrhofer-geo-uri-02), both expired and wildly different in the way they approach the standard. Is there an URI that's suited for encoding latitude and longitude and that made it as an RFC? Should I use a generic URI such as the tag
