Transferred from: http://www.cnblogs.com/gaojing/archive/2012/02/04/2413626.htmlThese two days when writing code, because of the location of the resources involved, so you need to define some fields in the Java bean to represent the location of the resources, such as: Imgurl,logouri and so on. However, every time the definition of time, the heart is very tangled, is to use Imgurl or imguri it?Similarly, another question: String Httpservletrequest.getrequesturi (); and StringBuffer Httpservletreq
The definition of the URI is: Uniform Resource Identifier;For a URL, the definition is: Uniform Resource Locator.The difference is that the URI represents the path to the requesting server and defines such a resource. The URL also shows you how to access the resource

After a long vacation, I had some trouble returning to the company. I was interrupted in my previous study plan and work plan. I didn't even know what to do when I came back. So I ran to my colleague's blog and came back to read my previous notes. Now I will continue to learn JavaScript.
A valid uri (Uniform Resource Identifier) cannot contain certain characters, such as spaces. Therefore, the URI must be e
When a URI passes a parameter in CI, it appears: The URI you submitted have disallowed characters. Error.
Cause: This is because there are characters in the URI that are not allowed by CI.
Workaround:In the config/config.php file, locateCopy the Code code as follows:$config [' permitted_uri_chars '] = ' A-Z 0-9~%.:_/-i ';
Add the allowed characters to the inside
If a reserved character has a special meaning in a particular context (called "reserved Purpose"), and the character must be used for other purposes in the URI, the character must be a percent encoding. To encode a reserved character, you first need to represent the ASCII value of the character as a two 16-digit number, and then place the escape character ("%") before it, placing it in the corresponding position in the

Definition:The URI is a string format specification and does not specify its purposeA URL is a specification of a resource's location, including a naming scheme for accessing resources, a host name for a resource, and the name of the resource itself, represented by a path.A URI is a lower-level abstraction of a URL, a string literal standard.

BackgroundThe project needs to construct a URI Scheme for itself, but does not know what the URI is and how the scheme is named, so the following information is found.InformationThe URL is very well understood, because it is common to locate Web resources on the Internet, such as an image on the Web, an MP3, or an address for a H5 page.Example: Http://www.baidu.com/img/bdlogo.pngThe

The relationship between URLs and URIs is outlined in the second article in this series: Java Network---Basic web concepts.One thing to repeat here is that the URI contains the URL, or the URI is the parent class, and the URL is the concept of the subclass.This article will elaborate on these 2 concepts.One: URLJava/net/url.java Public Final classUrlImplementsSerializable {Private Static Final LongSerialver
two functions were introduced in Javascript1.5. But since Javascript1.5 is already very popular, there is no compatibility problem with encodeURI and encodeuricomponent in practice.Unicode characters are encoded differently these three functions are encoded in the same way as ASCII characters, and are represented by a percent + two-bit hexadecimal character. However, for Unicode characters, Escape is encoded in%uxxxx, where xxxx is the 4-bit hexadecimal character used to represent Unicode chara
Data URI scheme allows us to include data in a webpage using inline-code, which can be used in Html, CSS, and Javascript.
Data URI scheme is often used to embed images into webpages. It is used as follows:
The data URI scheme format is as follows:Data: [
The format is relatively simple. We can see that the above img is a jpg image encoded with base64.Embed this
Uri is a uniform resource Descriptor (Uniform Resource Identifier). It is a mechanism used to describe resources on the Internet. We know that each web server resource has a name, so that other clients can reference and obtain the resource when they need it. The URI is like a postal address on the Internet, information resources can be identified and located globally.
