URL和URI的区别

初学java，最近被一个概念搞得头晕脑胀，就是url和uri的概念和区别，网上查了一大通，发现各种回答眼花缭乱，有百科直接粘贴的，有胡说八道的，有故意绕来绕去的，我估计他自己都没搞懂，按照马士兵的说法就是，通通都是一些冠冕堂皇的套话，说了等于没说，本来就是一个很抽象的概念，还用很抽象的的方式来答复，这不是让人虐心吗？经过我潜心研究了一番，把他们的区别分享给大家，我相信很多新手都不会一下子明白这两个概念的，老鸟勿喷！ 首先给大家举个例子，有一家公司的总经理，某天，给了我一张名片，上面写了他的头衔，北京XXX公司总经理 张三，还有他的办公室地址，北京市海淀区长安街35号北京XXX公司总经理办公室，那么，我以后给我的朋友吹牛，我认识北京XXX公司的总经理张三，我的朋友都知道北京XXX公司的总经理是一个叫张三的人，那么，这个头衔就和张三对应起来了，只要一说到这个头衔，大家都知道说的是张三，反应到网络世界，这个头衔就叫做URI，只要你给我一个URI，我就知道它代表了什么，比如，http://www.sina.com.cn代表了新浪网，admin@qq.com代表了某一个人的qq邮箱，你的qq号也是一个URI(腾讯服务器内可以识别就是你的QQ账户)，URI就是网络资源的头衔，通过URI标记可以把网络世界里面的每一个事物都加以标记并区分开来。 好的，现在出现了一个问题

Given a Uri and a UriTemplate, how to get template parameter values?

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-23 12:35:00
问题 If I have access to both a Uri and the UriTemplate on which is is based, what is the neatest way to discover the values that have replaced the parameters in the template? For example, if I know: var uriTemplate = new UriTemplate("/product-catalogue/categories/{categoryName}/products/{product-name}"); var uri = new Uri("/product-catalogue/categories/foo/products/bar"); is there a built-in way for me to discover that categoryName = "foo" and productName = "bar"? I was hoping to find a method

How may I bypass LWP's URL encoding for a GET request?

由 南楼画角 提交于 2019-12-23 12:28:46
问题 I'm talking to what seems to be a broken HTTP daemon and I need to make a GET request that includes a pipe | character in the URL. LWP::UserAgent escapes the pipe character before the request is sent. For example, a URL passed in as: https://hostname/url/doSomethingScript?ss=1234&activities=Lec1|01 is passed to the HTTP daemon as https://hostname/url/doSomethingScript?ss=1234&activities=Lec1%7C01 This is correct, but doesn't work with this broken server. How can I override or bypass the

Registering a custom URI protocol to handle custom resource loading from XAML

由 折月煮酒 提交于 2019-12-23 10:16:40
问题 I'm working on a project where loose bits of XAML (and some associated IronPython code) will be dynamically loaded and executed by a client application. The client will be using a custom WCF service (and some local caching) to retrieve the XAML, backing scripts, and related resources (icons, images, etc..). I would like to register a custom URI protocol/scheme to make it easier for the developers of the dynamic packages to reference their resources, like the following: <UserControl xmlns=

Can a path in a URI contain unicode?

由 北战南征 提交于 2019-12-23 09:29:23
问题 Is it possible for a valid URL to contain non-escaped Unicode characters? 回答1: Yes, the subset of ASCII (and therefore Unicode) that is allowed unescaped in URIs, such as letters and numbers. But the majority of the Unicode character set has to be percent-encoded. 回答2: URI and URL do not natively support unescaped non-ASCII Unicode characters, however many servers do allow percent-encoded UTF-8 or localized Ansi octets to be used (but no way of specifying which is actually used). For

Absolute URL from relative path

由 百般思念 提交于 2019-12-23 09:26:45
问题 I've got a base URL and some relative URIs in that document I want to have the absolute path of. E.g. base = https://example.com/some/path.html?query=string and relative URIs in that document: index.html → https://example.com/some/index.html .. → https://example.com/ ../../../../abc → https://example.com/abc abc/.. → https://example.com/some/ //example.org/ → https://example.org/ ftp://example.net/ → ftp://example.net/ In Java you have the class URL accomplishing that: URL abs = new URL(new

Should a given URI in a RESTful architecture always return the same response?

由 白昼怎懂夜的黑 提交于 2019-12-23 08:51:20
问题 This is kind of a follow-up question to this one. So is having a unique response for any given URI a core tenant of RESTful architecture? A lot of discussion here tends that direction, but I haven't seen it anywhere as a "hard and fast" rule. I understand the value of it (for caching, crawling, passing links, etc), but I also see things like the twitter API violate it (A request to http://api.twitter.com/1/statuses/friends_timeline.xml will vary based on the username given), and I understand
