Uri: Uniform Resource Identifier, a unified resource identifier, used to uniquely identify a resource. URL: Uniform Resource Locator, a uniform resource locator. It is a specific URI, that is, the URL can be used to identify a resource and also specify how to locate the resource. URN: Uniform Resource name, which is used to identify a resource by name. Uri is an abstract high-level concept that defines a unified resource identifier, URL and

Uri:uniform Resource Identifier, Uniform Resource Identifier;Url:uniform Resource Locator, Uniform Resource Locator;Urn:uniform Resource name, Uniform resource names.Where Url,urn is a subset of URIs.The basic form of an address on the web is a URI, which represents the Uniform Resource identifier. There are two kinds of forms:URL: The most common form of URIs today is ubiquitous URLs or uniform resource locators.An updated form of Urn:url, the Unifor

Like a postal address, he uniquely identifies and locates information resources around the world. There are two forms of URIs. Is the URL, the urn, respectively.3.

Project, you need to export data from the query results to the client, the previous solution is to generate an Excel file on the server through the excel component, and then download it. It can be divided into sheet, but the export is very slow due to memory consumption. It takes 40 minutes to export data from 60 thousand rows and 10 columns. I have never tried it. The following two solutions were obtained after improvement. Both solutions can generate the above data stream within several second

, but DTD lacks the flexibility;● The syntax of XML Schema fully complies with XML specifications and can be used in combination with DOM technology. It has powerful functions, while the DTD syntax is self-contained and difficult to learn.Therefore, schema is likely to replace DTD as a new Standard for verifying the legitimacy of XML documents.3. Basic Elements of SchemaSchema has eight elements: 1. The schema file is very similar to other XML documents. The root element is Xmlns = "

this method is not concise enough to see the result:Xmlns: S = "UUID: BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882"Xmlns: dt = "UUID: C2F41010-65B3-11d1-A29F-00AA00C14882"Xmlns: rs = "urn: Schemas-Microsoft-com: rowset"Xmlns: z = "# rowsetschema"> Name = "row"Content = "eltonly"RS: commandtimeout = "30"> Name = "productname"RS: Number = "1"RS: writeunknown = "true"> DT: TYPE = "string"DT: maxlength = "40"RS: maybenull = "false"/> Name = "unitprice"R

, to make the transmitted data meaningful, you must use the application layer protocol. There are many application layer protocols, such as HTTP, FTP, and TELNET. You can also define the application layer protocol by yourself. The WEB uses HTTP as the application layer protocol to encapsulate HTTP text information, and then uses TCP/IP as the transport layer protocol to send it to the network. 2.URI,URL, URNDifference URI: Uniform Resorce Identifier, which is a unified resource Identifier.

specific location of the resource, The protocol used to obtain resources is also indicated. A full URL contains the protocol name, the host name (IP or domain name), the port number (port number is not written by default to 80 ports), the path, and the 5 parts of the query string. For example: http://www.microsoft.com:80/images/hello.png?type=png. Such a URL, the above 5 parts are: Network Transport protocol name: HTTP, host: www.mcrosoft.com, Port number: 80, Path: Images/hello.png query strin
