In the development of the program we will assume that the external provided interface or data is not trustworthy. For example, the function is always to check the correctness of the parameters, in the unit test to the external interface provided by the shield off and so on. It's hard to make sure that you or someone else can provide an interface without any flaws. Since the interface is written by people, then there is a little bit of thinking about it, and when the interface is called, it is po

Introduction JSON format is one of our most commonly used serialization formats, the go language as a Google-developed, known as the Internet language of the C language, and naturally the JSON format support is very good. But the go language is a strong type language, the format requirements are very strict and JSON format, although there are types, but not stable, the go language when parsing the source of non-strongly typed languages such as PHP serialized JSON, often encountered some problems

Whether it is an array (arrary) or a linked list (list), it is indispensable in programming. Golang also has arrays, unlike other languages, Golang also provides slices (slice). Slices have better flexibility than arrays and have some dynamic chara
