There are 4 different methods to get current directory in golang. Method-1: The os package and Executable() function Method-2: file/filepath and the Abs() function Method-3: Using the osext package Method-4: Get the source file location
1.1 GOPATH Go所有的模块是通过go get命令来下载的,在Go版本1.5之前,下载好的模块被保存在$GOPATH/src文件夹下面,在《网络工程师的Golang之路》系列的开篇里讲解如何安装Golang时我们已经提到过GOPATH,GOPATH的绝对路径可以通过go env命令查看,如下图所示。

若你的程序要连接大量的服务器,且每台服务器只请求一两次,那收到请求后直接关闭连接。或增加最大文件打开数fs.file-max的值。 37. 将 JSON 中的数字解码为 interface 类型 在encode/decode JSON 数据时,Go 默认会将数值当做 float64 处理,比如下边的代码会造成 panic: ...
