1.
Golang工程调用另一个包的函数的时候，这个函数的首字母一定要是大写！
2.
构建工程之前，当前目录必须被添加到系统环境变量中的GOPATH中。
可以使用go install <packageName>来将这一个package添加到工程根目录的pkg文件夹中
（会生成一个和包名称相同的.a文件）
所以说，构建工程之前，需要先把src里面的所有包都go install 了，然后再对根目录进行go build
3. Test Related
go语言中的测试文件只需要写成XXX_test.go即可
测试的格式如下：
package test
import (
"testing"
//加上你要测试的库
)
func TestOk(t *testing.T) {
//进行测试， 如果有错误就t.Error(“XXXX”);报错
t.Error("sS")
}
And then perform in the root directory
go test -v ./...
You can run all the tests in the project file ...
4.travis-CI-related configuration
Two days out for a long time travis-CI's yml configuration.
At least I can read ...
Remember before_install inside the GOPATH into the $ HOME / gopath / src / + github repository
Reference: https://docs.travis-ci.com/user/languages/go/
Take a moment to engage in such a basically like this:
language:
- go
sudo: required
before_install:
- export GOPATH=$HOME/gopath/src/github.com/1171000106/SuitDatabase
script:
- cd src
- go install -a -v ./...
- cd ..
- cd test
- go test -v ./...
5.Golang file operations
I usually use is this
to read the file:
var f, err = os.OpenFile(filename, os.O_RDONLY, 0)
Write file:
f, err := os.OpenFile(filename, os.O_APPEND|os.O_WRONLY, 0755)
You can see the rest of this:
