基础语法
变量:常见变量类型包括int,float,bool等 声明如下两种:一种用var声明变量,另一种用:=自动识别类型
var a int
a:=1
if-else语句:和java,c语言差不多,不同之处在于if条件语句没有()
if 条件
else
go语言里面没有类似java,c里面的while,do..while,全部都用for代替
for{}
switch分支语句:go语言和其他不同在于可以在switch后不写条件,把判断条件放在case后面
数组:有固定长度的序列
切片:长度是可以变的,需要用make初始化,添加元素用append函数等其他方法
map:和java的hasmap差不多,即有key和v对应的value
range:可以用来遍历切屏等元素。

在线词典
我随便找了一个小众翻译软件,照着视频把对应的大部分流程走完,虽然没得到正确结果,但是在这途中学会一些知识并且了解到了两个实用网站 将url转为go Convert curl to Go (curlconverter.com)
将json转为go结构体 JSON转Golang Struct - 在线工具 - OKTools
