Golang Interfaceis a collection of method signatures used by a Type to implement the behavior of objects. The main goal of Golang interface is to provide method signatures with names, arguments, and return types. It is up to a Type to declare and implement the method. An interface in Gol...

(Update: And doesn’t let you use the return value.) You could use the function’s result, but you’d just immediately start waiting for it, defeating the purpose (I wonder why Go allows this at all.) Instead, to provide a result, a Go program would use a Go channel. Go channels...
Put(e) return buf, nil } 从上面的Marshal()函数我们可以看到,数据结构序列化后返回的是字节数组,而字节数组很容易通过网络传输或写入文件存储。而且在Go中,Marshal()默认是设置escapeHTML = true的,会自动把 ‘<’, ‘>’, 以及 ‘&’ 等转化为" " , "\u003e"以及 “\u0026”。 结构体序列化 go...
