golang monitoring

The Golang itself does not provide a driver to connect to MySQL, but it defines a standard interface for Third-party development drivers. Here to connect MySQL can use Third-party libraries, third-party libraries recommend the use of Https://github.com/Go-SQL-Driver/MySQL this driver, update maintenance is better. The following shows the specific use, the complete code example can refer to the last. Download driver sudo go get github.com/go-sql-driv

Golang a lot of open source projects, but there are few official editions. Sometimes the choice is weak, choose a good popular components, can go a lot less detours. Organize some of the most famous and useful open source components (continuous update) 1.web Framework Beego Go get Github.com/astaxie/beego Http://beego.me2. Database MONGO (most likely to be the official pkg) Go get gopkg.in/mgo.v2 Http://labix.org/mgo Mysql Go get Github.com/go-sql-dri

function Declaration The function uses the FUNC keyword declaration, except that the type is post-built, and the rest is similar to the rest of the language. In particular, like variable declarations, if the type of a function parameter is the same, you can add the type only at the end. Func Add (A, b int) int { return a + b } function return value The Golang function can return multiple values, which are similar to the attributes of the return

follow the code to learn Golang language. Today we are studying the built-in data structure of the Go language: A dictionary (map). ----------------------------------------------------------------------------------------------------------- ----------------------------------------------------------------- dictionary (MAP) A dictionary (map) is a data structure built into the go language, a set of unordered sets of key-value pairs. Some places are calle

There are two ways to initialize a struct in **golang: 1. Declare the key of all fields, 2. Neither declares key, but value corresponds to the order one by one defined. Although mode 1 is cumbersome, anonymous fields may not have to be initialized when there is an anonymous field in the defined struct, and the anonymous field needs to be initialized in mode 2, otherwise the compiler will error (too few values in struct initializer)."Subclass" in

# #Golang unittest Unit Test Golang unit tests have strict requirements on file names and method names, and parameters. For example: 1, the file name must be named Xx_test.go 2, the method must be test[^a-z] Start 3, the method parameter must t *testing. T Before because the 2nd did not write right, led to find a half-day error. Now really memorable, ah, little things were not carefully read. Let's share

coverage testing in the Golang Golang provides a number of tool chains that can be used to facilitate unit testing, analyze performance bottlenecks, provide runtime information, and so on, all of which are useful. Go test This tool people should use more, I used to do mostly for unit testing, go to do unit testing is very convenient, but I ignored the coverage test. How much code does the unit test cover?

solving the problem of sticky packets in TCP transmission in Golang Author: Yu DongweiEmail:usher.yue@gmail.com What is a sticky bag. Recently in writing https://github.com/UsherYue/ActivedRouter (a HTTP/HTTPS reverse proxy service) encountered a sticky packet problem, If there is a network programming of the small partners should be aware of the sticky packet problem, for example: the client in the kimono Use JSON-formatted packets for communicatio

As a low-level technology, blockchain technology from the initial digital money to smart contracts to the current industry scenarios distributed application implementation, since 2008, 10 years ago, the blockchain from the original theoretical concept to today's actual scenario application landed, although questioned but have been hard to move forward. Especially in the last two years, the re-construction of the existing industry logic in blockchain has made it undisputed the next development of

bloated, and the lack of system programming genes, after all, it is enterprise development origin of the last I chose Erlang, because it is excellent in the network layer performance, At the same time fault tolerance and robustness are very good, its virtual machine is the only one comparable to the JVM, but also the OTP super-heavyweight weapons, almost can be a Kill network layer application, but according to my summary it has a mishap and a soft rib, this point behind the expansion, It can b
