Objective In this article and in the next article, we will study Golang's source code to explore how Golang implements HTTP URL matching, and compares the implementation of the MUX.I have limited level, if there are omissions and incorrect places, but also please enlighten me, thank you! Golang source based on 1.9.2 Bo

The native data types of Go can be divided into basic types and advanced types, the basic types mainly include string, bool, int and float series, the advanced type contains Struct,array/slice,map,chan, Func. Compared to the language of reference types such as Java,python,javascript, Golang has a relatively ancient character like the C-language pointer. But unlik

Programming interface Internal data structure Listener and TcpListener In simple terms, one is an interface, and the other is a concrete implementation. Because Golang support TCP, UDP and other protocols, natural use of Golang interface. Listener defines the various interfaces for the socket operation: type Listener interfac

After use, it's good to see, Let's share it with you. data type lua corresponds to the data type in Golang the author has already explained in the document, it is

read the official Google Golang document, finally got some clues. Concurrency is not equal to parallel Golang's core developer, Rob Pike, specifically mentions this topic (interested in watching this video or reading the original PPT) Although we used go to create a goroutine in the For loop, we thought that, of course, each time the loop variable was executed, Golang would definitely execute the goroutine

This article is from the Golang core Development group Andrew Gerrand in the Google I/O 2014 theme Sharing "Testing techniques", that is, the use of Golang development will use the test technology (mainly for Unit test ), including the basic technology, advanced technology (concurrency test, mock/fake, competitive conditions test, concurrency test, internal/external testing, vet tools, etc.), and so on, th

You can use time in Golang. The time data type to hold isodate times in MongoDB.GType Model struct {uploaddate time. Time ' Bson: ' uploaddate ' '}m: = model{}if Err: = C.find (nil). Select ({"_id": 0, "uploaddate": 1}).One (m); Err! = Nil {fmt. Printf ("Failed to find date, error%s\n", err) OS. Exit (1)}fmt. Printf ("%+v\n", m)From the output you can see that the time format of the Golang output is the CST

In order to be able to reuse the existing C language library, we will inevitably encounter go and C language mixed programming when using Golang development project or system, many people will choose to use CGO. Say CGO this thing can be considered to be a person to love and hate, the advantage is that it allows you to quickly reuse the existing C library, no need to re-build the wheel with Golang, and the
