The Go language provides an HTTP package that makes it easy to develop an HTTP interface. The following is the sample code:Package Webserverimport ("Encoding/json" "FMT" "Net/http" "Time") func webserverbase () {fmt. Println ("This is webserver base!") The first parameter is the interface name when the client initiates an HTTP request, and the second parameter is a func that is responsible for processing the request. http. Handlefunc ("/login", Logintask)//server to listen on the host address an

Install fingerprint identification on X220/T530Ubuntu14.10/LinuxMint17.1 On Ubuntu, you can install fprint-demo and fingerprint-gui as the fingerprint recognition software for ThinkPad. I tried fprint-demo, which can be used with the Ubuntu SYSTEM account, but the recognition effect is poor. Fingerprint-gui runs as an independent fingerprint software, and the recognition effect is good. Therefore, finger

Bad2}Type Bad2 Interface {Listen to Bad1} Null interface (Empty interface)The null interface is special, and it does not contain any methods: Copy the Code code as follows: interface{} In the go language, all other data types implement an empty interface. Copy the Code code as follows: var v1 interface{} = 1var v2 interface{} = "abc"var v3 interface{} = struct{X int}{1} If the function intends to receive any data type, the reference can be declared as interface{}. The most typical exam

This is a creation in Article, where the information may have evolved or changed. Some understanding after reading this article 1 io. Writer interface Io. The writer interface is defined as follows Package IO Type Writer interface { write (P []byte) (n int, err error)}//According to the features of the interface in go, all implemented the type of the Write method, we say it implements IO. Writer interface. 2 SOMEPKG.ABC type implements the Io.writer interface Package Somepkgtype ABC

receive any data type, the reference can be declared as interface{}. The most typical example is the functions of the print and Fprint series in the standard library FMT package: func Fprint(w io.Writer, a ...interface{}) (n int, err error) func Fprintf(w io.Writer, format string, a ...interface{})func Fprintln(w io.Writer, a ...interface{})func Print(a ...interface{}) (n int, err error)func Printf(format

, 2, 3, 5, 8 ...Write a fib class in which Fib (10) represents the first 10 elements of the sequence, printFib prints the first 10 elements of an array, and Len (fib ) Returns the number of numbers 10 correctly.Code Listing 1: (reference Code)You can use STR () to convert an integer list to a string.Class Fib (object):def __init__ (self, num):a, b, L = 0, 1, []For n in range (num):L.append (a)a, B = b, A + bSelf.numbers = Ldef __str__ (self):Return STR (self.numbers)__repr__ = __str__def __len__

the next data needs to be returned.IteratorIt can even represent an infinitely large stream of data, such as the whole natural number. Using list is never possible to store all natural numbers.SummaryAny object that can be used for for the loop is a Iterable type;All objects that can be used for next() functions are Iterator types, which represent a sequence of lazy computations;Collection data types such as list , dict ,, and str so on are Iterable not Iterator , however, you can iter() get an
